The entire HIS for the Heihe River Basin adopts the ODM (Observation Database Model), WebGIS and Web service using the watershed science data from the Heihe River Basin. Therefore, a hydrologic information sharing was established with such functions as hydrologic observed data retrieval, browsing, online service and analysis by an application case in the Heihe River Basin, a typical inland river in the northwest China.","PeriodicalId":6394,"journal":{"name":"2012 International Symposium on Geomatics for Integrated Water Resource Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87507864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The kinetics and equilibrium of biosorption were examined in detail. Three kinetic models (pseudo-first order, pseudo-second order, and internal diffusion order model) were used to connect data and to determine the kinetic parameters. Two well-known adsorption isotherms were chosen to describe the biosorption equilibrium. The experimental data were analyzed using two two-parameter models (Langmuir and Freundlich). The equilibrium biosorption isotherms showed that peanut shells possess high affinity and sorption capacity for Acid Red, maximum biosorption capacities of 9.8232mg/g. All results showed that peanut shells biomass is an attractive, alternative low-cost biosorbent for removal of heavy Acid Red from aqueous media.","PeriodicalId":6394,"journal":{"name":"2012 International Symposium on Geomatics for Integrated Water Resource Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89270629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The water quality data of 34 sites for five indicators, Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD5), Total Nitrogen (TN), Total Phosphorus (TP), and Dissolved Oxygen (DO) between 2001 and 2010 were analyzed. The spatial trends of water quality for the 2000s were presented. An interpolation approach based on the distance along river network was used to reveal the spatial variation of water quality in year 2010. A non-parametric seasonal Mann-Kendall's test was employed to determine the significance of temporal trends for each parameter of each site. Basically, the water quality of the Min River basin is good and most of the segments can satisfy the national environmental standards of Class III. Moreover, certain spatial and temporal patterns can be discovered through the analysis. The best water quality is in the Dadu River, the Qingyi River, and the upper parts of the Min River. The water quality of the Fu River is the worst in the basin. The middle parts of the Min River are worse than the lower parts and better than the Fu River. From temporal perspective, COD showed significant upward trend, whereas BOD5 showed significant downward trend. TN and TP showed increasing trends in a similar spatial manner, which exhibits the signs of degradation in water quality. Particularly, the concentration of TN exhibited significant upward trend. Nevertheless, DO showed some upward trends. The reasons of the spatial-temporal characteristics were also discussed and some water management strategies were recommended.","PeriodicalId":6394,"journal":{"name":"2012 International Symposium on Geomatics for Integrated Water Resource Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91533448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper is to achieve an all-win situation in use of Mekong water resources through cooperation. A game named “The Mekong Game” was designed for those Ph.D. students and resource persons to play on the PROSPER.NET's workshop. For a hypothetical case in Mekong Game, the Shapley Value Method's results were given, which could be regarded as one of equitable results in theory, and the Mekong Game's process and outcomes are introduced in this paper. Participants were divided into six groups representing six involved “countries”. The process of meeting an agreement with an all-win idea was simulated through three round-table negotiations. The results reveal: although it is harder to get theoretical optimal aftermath considering other complicated factors than those which can be calculated, the all-win situation is still possible through bargaining and negotiation processes, which should be much better than all-lose situation such as the current one.","PeriodicalId":6394,"journal":{"name":"2012 International Symposium on Geomatics for Integrated Water Resource Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80859021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
