Focusing on the innovation of the ecological compensation mechanism for the national water network project, this paper systematically identifies the multiple stakeholders in the water source areas and along the water transmission routes, with the ecological protection costs, benefits from ecological service value, and demands for rights and interests in regional development deeply analyzed. Meanwhile, a method for determining the ecological compensation standard based on game theory is proposed, which takes the total ecological protection cost of the water source areas as the lower compensation limit and the incremental value of ecological system services in the water source areas as the upper compensation limit. The bargain game model among multiple stakeholders is introduced to determine the final ecological compensation standard value. During the construction period of the project, the focus of the game is concentrated on the dispute over the discount rate of intertemporal cost sharing. During the operation period, the game equilibrium is complicated due to technological substitution and demand fluctuations. Therefore, a dynamic game mechanism is introduced to transform the process of determining the compensation standard into strategic interaction among multiple stakeholders. As a result, this ensures the basic ecological investment while stimulating the positive externality transformation of ecological protection, thereby promoting the Pareto improvement of ecological compensation and providing theoretical support and practical approaches for the sustainable operation of the national water network project. Additionally, it is recommended that an accurate cost accounting system should be established, the market-oriented path to realizing the value of ecological products should be investigated, and the coordinated evolution of water resource protection and regional development should be promoted by the establishment of a dynamic adjustment mechanism for ecological compensation standards.

ABSTRACT Water is the most important substance in nature and all known life forms on the planet depend on it. Among aquatic species, microalgae and cyanobacteria stand out as indicators of their quality, as their increase can be harmful for human consumption, and their concentrations should be monitored. This research aimed to identify reflectance patterns of the microalgae Chlorella vulgaris and Raphidocelis subcapitata that allow, through the creation of an algorithm, the estimation of their chl-a concentrations. The R software found that cell density and growth were higher in C. vulgaris Pearson correlation of 0.96 (p-value 0.000041) and Chl-a content was higher in R. Subcapitata Pearson correlation of 0.81 (p-value 0.013778). An algorithm made it possible to edit the dependent variable based on statistical models. The best readings for the microalgae used were in the spectral range of 524.84 nm in R. subcapitata and 671.13 nm in C. vulgaris. The use of the spectroradiometer for such an analysis, previously unprecedented, was due to the best cost-benefit for measuring the reflectance of Chl-a. It is expected that these two equations will be used in satellites to remotely check water quality through the incidence of these microalgae.

Contamination of water bodies by heavy metals is a continuously growing environmental issue. High concentrations of mercury (Hg) in river waters are a recognized environmental problem, because it is one of the most toxic heavy metal ions as it causes damage to the central nervous system. Its negative impact has led to the development of different methods for the treatment of effluents contaminated with Hg(II). The aim of this article is to evaluate the use of coffee ( Coffea arabica) residues as adsorbent of Mercury in an aqueous solution. Four kinetic models, including intraparticle diffusion, pseudo-first-order, pseudo-second-order, and Elovich kinetic models were applied to explore the internal mechanism of mercury adsorption. Results indicate that the pseudo-first-order and pseudo-second-order models could accurately describe the adsorption process. It means that chemical adsorption play an important role in the adsorption of mercury by activated carbon. Meanwhile, the external mass transfer process is more effective in controlling the activated carbon mercury adsorption according to the fitting result of the pseudo-first-order model. The fitting to Langmuir’s model suggested that the material surface is energetically homogeneous. The technique of contaminated biomass encapsulation proved to be safe for short-term disposal when metal recovery is not desired.

DEM is one of the most important digital twin basic data and has played a huge role in water conservancy planning,design,and engineering construction.However,the existence of various DEM errors greatly reduces the credibility of analysis and application results.In particular,the missing value after terrain conversion to DEM greatly limits subsequent DEM-based analysis.Based on the principle of raster calculation,this paper calls the corresponding tool of ArcGIS by Python to correct the missing value at the overlapped area of a certain terrain converted to DEM by using the mean of eight valued pixels around the pixel.The results show that the calculation method is highly applicable,reliable,and fast.The data of the corrected and compared values of 306 NoData pixels in the study area are close to the 1∶1 line;the maximum difference between the corrected and compared values is only 3.55 m,and the medium error value is 0.75,which is far below the standard error limit.Calling Numpy through Python greatly improves the calculation speed (10 s),and ArcGIS currently has no tool for directly correcting this method.In contrast,the DEM correction method proposed in this paper can be processed in batch,without processing failures due to memory limit,which greatly improves the work efficiency and has a strong application value for processing digital twin basic data.

ABSTRACT This study evaluated the water sources at the points of water collection for human supply, identifying conventional and emerging pollutants that could compromise the public supply of the municipality of Cuiabá-MT. Raw water was analyzed at three water pumping sites, using secondary (2014 to 2019) and primary (June and November 2019) data. The parameters described in current regulations were used to calculate the Index of Conformity with the Guidelines, which assesses the distance between planned quality and measured quality. Drugs were discussed based on ecotoxicological studies. There was a reduction in the quality of water sources in the urbanized area, with the disposal of in natura domestic sewage and surface runoff as the most important causes of this reduction. Measures are needed to expand and ensure adequate and efficient collection and treatment of effluents, preventing pollutants from reaching rivers.

In order to improve the evaluation system for the water conservancy photography creation base, evaluation indicators regarding the aspects of photographic resources, photographic elements, and water resources were selected to construct an evaluation index system, and the evaluation criteria for each index were provided. The optimal comprehensive weight for each evaluation index was determined following the moment estimation theory. The quantitative evaluation of the water conservancy photography creation base was carried out combined with the scoring standards for each index. The evaluation index system constructed here was then discussed in the application. This indicated that the evaluation index system is suitable for determining the construction status of the evaluated cases, thus verifying its rationality. The comprehensive weighting of the indicators based on the moment estimation theory made the evaluation method more scientific and the corresponding results more reliable. This enabled the entire evaluation system and method to provide the theoretical support for the scientific evaluation of the water conservancy photography creation base. HIGHLIGHTS The concept of water conservancy photography creation base is put forward for the first time.; Construction of the evaluation index system for the water conservancy photography creation base.; The application research on the evaluation index system is carried out.; Determine the comprehensive weight for each index by the moment estimation theory.; Use of two evaluation methods to validate the rationality of the evaluation results.;

Lake and its inflow rivers compose a highly linked river-lake system, within which sediment and water are also closely connected. However, our understanding of this linked and interactive system remains unclear. In this study, we examined bacterial communities in the sediments and surface waters in Poyang Lake and its five tributaries. Bacterial communities were determined while using high-throughput 16S rRNA gene sequencing. The results showed significant differences of bacterial communities between sediments and surface waters, as well as between Poyang lake and its tributaries, suggesting that the river-lake system of Poyang Lake provides diverse and distinct habitats for bacterial communities, including lake water, lake sediment, river water, and river sediment. These biomes harbor distinct bacterial assemblages. Sediments harbor more diverse bacterial taxa than surface waters, but the bacterial communities in surface waters were more different across this river-lake system than those in sediments. In this eutrophic river-lake ecosystem, nitrogen and phosphorus were important drivers in sediment bacterial communities. Nitrogen, phosphorus, and dissolved organic carbon, as well as their stoichiometric ratios affected bacterial communities in surface waters. Moreover, network analysis revealed that the bacterial communities in surface waters were more vulnerable to various disturbances than in sediments, due to lower alpha diversity, high complexity of network, and a small number of key taxa (module hubs and connectors). Nutrient variables had strong influences on individual operational taxonomic units (OTUs) in the network, especially in bacterial network in surface waters. Different groups of taxa responded differently to nutrients, with some modules being more susceptible to nutrient variations. This study increased our current knowledge of linked river-lake ecosystems and provided valuable understanding for effective management and protection of these ecosystems by revealing bacterial communities in sediments and surface waters in Poyang Lake and its tributaries, as well as their responses to nutrients variation.

A qualidade físico química da água subterrânea é importante uma vez que determinados tipos de uso dependem fundamentalmente desses parâmetros. O objetivo deste trabalho foi avaliar a qualid ade das águas subterrâneas de um conjunto de poços tubulares existentes no município de Marialva - PR, e por meio do agrupamento hierárquico avaliar as características iônica s das águas. Para isso, foram realizadas análises de condutividade elétrica, pH, temperatura e oxigênio dissolvido, dureza, sulfato, cloretos, nitrato, sódio, magnésio, cálcio e turbidez. A análise dos dados foi feita a partir do software livre QualiGraf, no qual foi elab orado uma análise de agrupamento hierárquico aglomerativo utilizando a distância euclidiana e o método Ward. Com os agrupamentos das variáveis analisadas nos poços form ou-se 4 grupos distintos de classificação de águas.

A eletrocinese é uma técnica de remediação emergente e vem sendo bem estudada com o objetivo de remediar áreas com contaminação de metais ou para auxiliar o transporte de espécies iônicas em outras técnicas de remediação. No entanto, existem outras formas de uso desta técnica pouco exploradas que também podem ser interessantes para a remediação e que, para tanto, foram testadas neste trabalho. Foram realizados ensaios em um modelo físico 2D utilizando a eletrocinese simples e associada à oxidação química com o oxidante persulfato visando a degradação do tolueno em um solo argiloso. Os resultados indicaram dessorção e degradação do contaminante com ambas as técnicas, ocorrência de fluxo eletroosmótico do tolueno em direção ao catodo, direcionamento e acumulação do oxidante devido à eletromigração e potencial de ativação do oxidante. Assim, foi possível concluir que a técnica eletrocinese apresenta versatilidade e pode ser aplicada de diversas formas na remediação.

While determining theoretical flood hydrographs, different methods of their construction are used depending on the needs of the problem or the scope of the project. It should be remembered that these methods differ mainly with the principle of the waveform averaging, which may be done either according to the flow or time. The hydrographs may be divided into nonparametric (determining on the basis of registered floods) and parametric (using mathematical description of the flood course). One of the analytical methods is Strupczewski method which has two parameters: responsible for the waveform and specifies the base flow, the flow above which values of hydrograph are calculated. The functional description uses the Pearson type III density distribution.

This paper establishes a three-dimensional maritime search and rescue plan by integrating a differential equation model, a global optimal model and an area partition algorithm. Based on the data of flight data and the loss time of communication for MAS MH370, we establish a differential equation model to determine the search scope of the sea area, and determine the place where the plane fall into water. After the plane falls into water, the plane will be moving in the water due to the effect of sustained ocean currents, thereby we establish a differential equation model. By solving this model, we obtain that the search scope is a circular area of 2000 square miles with a coordinate of circle center. Introduction With the development of economy, the plane has gradually become one of the convenient traffic. Plane flying does not be limited from the mountains, rivers, deserts, oceans and other geographical conditions, and can increase the number of plane according to the passenger source and the supply quantity. According to the statistics data from International Civil Aviation Organization, the average number of deaths in per one km is 0.04 people, and it is safer way than the train transportation. The plane’s disadvantage is expensive, and heavily influenced by weather. Although the plane accident rate is very low, once the plane crash happens, very few people survived or even no survivors. Therefore, maritime search and rescue is a very complex and vital activity. When distress target location is unknown, we must carry out maritime search and rescue. Search operation is the most expensive, the most dangerous and the most complex part in the whole search and rescue process, is also the only way to find and rescue the survivors. Making process of search action plan of the sea are generally considered more complex, so this paper takes a Boeing 737 crashed plane as an example, the searching process of sea action plan is divided into three steps: 1) Determine the specific scope of search area (i.e. to determine what kind of search power to participate in the action); 2) Determine the search partition and search way (i.e., to determine how these search powers act). And then we design a search plan after these three steps. The model In order to determine the specific scope of search area, the whereabouts process of plane is divided into two stages: (1) The falling process of the plane in the sky. In this stage, we will determine the place where fall into water. (2) The falling process of the plane in the water. Considering the sea buoyancy and the effect of ocean currents, we will determine the specific scope of search area. Due to too many indexes for crash problem of different type plane, in order to simplify the problem, we take the Boeing 737 plane as an example. Suppose that the plane lost power at one point from A to B over the sea, the airplane flying in the air and generate the resistance f with the opposite direction of its movement. Because of the Earth's gravity, the plane has the gravity G. And upper and lower wing surface flow velocity are inconsistent, so that the wing generates lift F. The projected point of the plane on the sea as the origin, northeast 45° is the X-axis, and the vertical direction is Y-axis. In 4th International Conference on Mechatronics, Materials, Chemistry and Computer Engineering (ICMMCCE 2015) © 2015. The authors Published by Atlantis Press 1384 this coordinate system the initial coordinates of the plane is (0,10000) , and the initial plane velocity is parallel to the X-axis direction. After plane lost power, speed and direction of movement, posture, air resistance and aerodynamic plane are changes over time change, so this is a typical problem of fluid dynamics. However, in order to simplify the model, we suppose that lift F is a given value, and the direction is always perpendicular to the direction of motion of the plane. Usually, when the object is not large and the moving speed is relatively low, we can suppose that the resistance is proportional to the speed if the object speed is less than 10 m/s, and in general within the range of considerable velocity and size of the object, it can be assumed that the resistance is proportional to the square of the speed from 10 m/s to approach or exceed the speed of sound. If the object speed exceeds the speed of sound, then a sharp increase in resistance, and the resistance is proportional to high power of the speed [1]. The relative literature data are listed in the following Table 1. Table 1. Air density data under certain altitude Altitude (m)
