The Optimization of Groundwater Dynamic Monitoring Network – An Example of the North Ordos Basin

Groundwater management is base on an sufficient dynamic monitoring network of groundwater depth and quality. Whil the monitoring network in Ordos Bain is insufficient due to the network is not been finished yet. Thus, in this paper, the dynamic type mapping method of groundwater based on GIS developing is used to optimize the distribution of dynamic monitoring positions. The purpose of the optimization is to observe reginal dynamics of groundwater with less monitoring wells. The reginal groundwater depth has a impact of hydroecology. Thus the optimization also consider the distribution of vegetations which are closely related with groundwater. The optimization shows that at least 28 new monitoring wells are needed depend on the existing groundwater monitoring network. The monitoring positions of 28 new wells are also estimated by the method.
