Numerical Simulation Of Groundwater Flow In Zoige Wetland Protected Region

Zoige wetland natural protected region, with 166570.6hm2 area, which is characteristized by humid and semihumid monsoona climate of plateau, lacates in the eastern Qinghai-Tibetan Plateau at 3422m to 3697m. There are more lakes, rivulets, lower hills, meandering rivers and large meadow in the wetland. With the population increasing and economy deweloping, water table in the wetland descending rapidly.The groundwater flow in Zoige wetland been influenced by the National Way 213, which goes through Zoige grassland from Langm temple to ChuanZhu temple ,of which sixty kilometers hemes Zoige natural wetland protected region. To simulate the groundwater flow in the wetland ,a pumping test that three pumping wells and nineteen observation bores were designed was done in Axi grassland near the highway at K5+500 to K59+500 last year.According the hydrogeological conditions, a conceptional model of groundwater flow is set up for the research area that is divided three subareas. Based on the model with observation data from the pumping test, a mathematic model is established so that the numerical model is obtained by employing the Finited Difference Method(FDM). GMS, a wisual system of groundwater numerical model is used to identify aquifer parameters such as hydrautic conductivity(HC),specific yield(SY) and transmissibility coefficient(TC) and predict the groundwater flowfield...
