Study on feature storage and storage capacity of underground reservoir based on GMS in MHS area of Beijing, China

摘要

An underground reservoir is an effective way to solve water resource problems, such as uneven water distribution and shortage. Based on the groundwater overdraft status in Beijing, the hydrogeologic conditions in Miyun-Huairou-Shunyi (MHS) area, and the excess water of Middle Route Project of South-to-North Water Transfers in Beijing, 3D strata spatial geological structure models are developed by software Groundwater Modeling System (GMS). Different types of water levels and their corresponding feature storage are illustrated to assess the storage capacity of the underground reservoir. The storage capacity is analyzed in the MHS area according to the models and water levels. The total storage is about 31.11 x 10(8) m(3). The dead storage is approximately 15.07 x 10(8) m(3), and the beneficial storage is approximately 16.05 x 10(8) m(3). Results present important reference for the construction of underground reservoir in Beijing. The construction is important in solving the serious water shortage problem in Beijing.
