Dynamic simulation and overdraft evaluation of Huaibei karst water field

Based on the study of actual exploitation of fracture-karst water in Huaibei City, the water level dynamic simulation model is built up by using the coupling method of water level autoregression and multivariate regression. According to the dynamic simulation process and results of the actual levels in the period from 1997 to 2004, the coupling method can produce high calculation accuracy, and the advantages of the method are described. Based on the dynamic feature of the regional water levels, the causes of excessive extraction of fissure-karst water are analyzed.The determination method of a limiting water table is discussed from the perspective of fair water, and the dynamic simulation model is used to evaluate the extent of excessive extraction of water. Based on the dynamic features of regional water levels and the overdraft evaluation results, the technical scheme for pumping limitation in the study area is discussed.
