Abstract: ： Since the lack of unified planning, continuous expanding development and utilization of shallow groundwater might resulted partial imbalance in Jiangyan district. Based on the hydrogeological conditions and the parameters from pumping tests, a mathematical model of hydrogeologic in Jiangyan district was established by using Visual MODFLOW software. After continous adjustion of the parameters, the model was proved to be reasonable and effective for its good fitness on water level simulating. It can truly reflect the local hydrogeological conditions, and could be used to predict the shallow the groundwater level in Jiangyan district, and further predict the exploitable amount in future 10 years with the water level as control index. The results showed that the exploitable amount of shallow groundwater in Jiangyan district is 4.670 4 million m³/a till 2030 if current exploitation conditions unchanged. Compared with the actual exploitation situation, the exploitation and utilization potential of shallow groundwater in the study area is 76.41, which was far greater than 1.2. It indicated that under the current mining conditions, the shallow groundwater in the study area still has a certain mining space. Therefore, it is necessary to guide the development and utilization on the shallow groundwater in the study area in strict accordance with the distribution map of the remained shallow groundwater, and arrange the wells scientifically and reasonably at the potential areas.
