The project contents includes: （1）finishing one delineation of cross border river （Huang River）and 11 counties/ cities bulletin drafts about river water zones; （2）investigation and evaluation of pollutant and the amount of pollution of impaired of water bodies; （3）delineation improvement strategies of impaired water bodies quality; and （4）investigation and survey the status of using water bodies of 17 delineated river water zones, and reviewing the adjustment of water zones also the bulletin matters.
In order to facilitate the delineation works of river water zones, this project takes the relative research results of river water delineation in recent years inside country as references, also takes the United States and EU’ s water zones delineation and using water bodies as considering factors. After experts and scholar consultation meetings, decided the “Bulletin Working Procedures of River Water Delineation” and the “Delineation Principals of River Water Zones” drafts. The former one includes: （1）basic information collection and analyzing; （2）sites exploring; （3）water bodies classification review; （4）study meeting, drafts declaration and public hearing; （5）procedures declaration etc. The latter one includes: （1）according with the classification of water bodies usages; （2）protection the status quo of water quality and （3）considering the characteristics of natural water bodies and water quality repairing reachability.
For finishing one delineation of cross border river （Huang River）and 11 counties/ cities bulletin drafts about river water zones, we should collect basic data and analyzing it, such as river basin, land using survey, water using survey, pollutant and the amount of pollution survey and estimation, 1Y75（75% water sample qualified standard in a year） of water quality evaluation results within 10 years. Also conduct 12 river site exploring works for understanding the status quo. According to the collection data and the exploring results, proposes 12 draft suggestions of river water bodies classification. Through the consultation meetings of experts and scholars, decided 12 bulletin drafts of river zones before study meeting and after illustration meeting.
To sift 12 new delineation river water zones and bodies out of impaired reaches and quality, the project is going to use 1Y75（75% water sample qualified standard in a year）, 5Y75（75% water sample qualified standard in 5 years）, C75（75% percentile concentration qualified standard in 5 years）to evaluate the water quality in recent 5 years, so that to judge the impaired reaches and quality items. Also consider the polluted level and usages to decide which should be the priority improvement, and make whole polluted improvement strategy for the reach in short term, middle term and long term. Completion of compiling of “Improvement Strategy Planning Reference Guild of Impaired Water Bodies Quality” and manage “Improvement Strategy Planning Reference Guild Workshop of Water Zones Delineation and Impaired Water Bodies Quality” as propaganda for policies and environmentalists education training tools.
To review the 17 delineated river water zones of water zones also the bulletin matters, the project investigates all bulletin matters of 17 delineated river water zones, in order to unified the forms and enhance the integrity to comply with existing state. To redraw the bulletin water zones and to survey the quality standard water body usage, segmented point and administrative division of each reach, so as to propose adjustment suggestions and revision the declaration contents of bulletin matters.
For the purpose of predominating the relative information of water zones for users, the project uses Google Earth API to build a internet GIS platform for water zones delineation（http://140.116.249.139/epa/index.php）. In the aspect of water zones sphere and water bodies usages, the platform contains water systems, catchment area, sub-catchment area, sewage collection area, land usage（existing state）, non-city using zones（planning）, main roads and water intakes. On water quality aspect, the system including regional geology, faults, satellite images（landforms and vegetation）, topography（gradient shadow）, water quality monitor stations, flow stations, and rainfall stations. Interest in the relationship on water usage, including water rights information, village borders, main roads, water quality protection area, reservoir and restrict developing area. On the aspect of water quality standard and remediation strategies, the platform serves the estimate of water quality（report documents）, bulletin drafts（report documents）, classification demarcation points（represent by colors）, regulated pollutants, and water quality monitor stations. Through the aforementioned platforms, cam make direct authorities much more understands the water zones delineation and basic information, also uses the same platform to make river water delineation decision.
