North Water Transfer Project of Xiangfan city simulation and prediction of the impact of groundwater


intheurbanwhenfiverwaterdown0.52m1. Falling water tables contours (figure decreased value, unit: m); 2. Analog range boundaries. 5 the impact of falling groundwater levels due to falling water tables, will be mainly caused by the negative impact of the following two aspects: First, reduce the amount of groundwater resources. According to preliminary projections, the simulation area a terrace unconfined aquifer pore volume storage capacity will be reduced by 2.503 billion cubic meters. According to the survey,tods shoes outlet, there are Xiangfan City West Industrial Zone Fan and Zhang Xiao Wan Wan, two due to excessive exploitation of underground water to form the cone of depression, after declining groundwater levels, groundwater resources, further reducing the amount of some over-exploitation of groundwater has to Xiangfan City that will undoubtedly be worse, it must be further reduced extraction; second is caused by extraction of groundwater along a terrace of motor-pumped well water pumping costs increase, the individual with the current water table depth less motor-pumped well and may even scrapped. 6 Conclusion Water Transfer Project is running, Dan reservoir discharged flow reduction,herve leger toronto, under the Han River water level (in Xiangfan City, for example) will inevitably decline with the pore water is closely linked to groundwater level has decreased in varying degrees, and the resulting reduce the amount of groundwater resources, motor-pumped well water pumping costs increased, individual motor-pumped wells may be scrapped.
