Research of Poyang Lake Conservancy Project Hub Influence to Iron and Manganese of Groundwater

Abstract:

The problem of iron and manganese in Poyang Lake groundwater is serious. The proposed Poyang Lake water conservancy hub project may influence to iron and manganese of groundwater. These means historical data, field survey, statistical analysis, numerical simulation and so on were adapt, and Gan River Delta was selected as typical research area to aim at Poyang Lake water conservancy hub project influence to iron and manganese of groundwater. A numerical model of flow and transport on the basis of regional hydrogeological condition and 83 borehole data was developed to evaluate the influence. The boundary conditions were determine on the basis of regional geological and hydrogeological data, dynamic relationship between groundwater and river, regional digital elevation model, the history of formation and evolution of Poyang Lake. Then the model was used to simulate the project impact to iron and manganese of groundwater in spatial and temporal trends under conditions of long-running according to the recommend dispatch program of Poyang Lake water conservancy hub project. The result was that the concentration of iron and manganese in groundwater heightened a little and the potential environmental problems were unlikely.
