Estimation of Groundwater Recharge Based on the Corrected Remote Sensing Data:A Case Study of the Taigemiao Mining Area in Ordos Basin
摘要
Abstract
The groundwater recharge acts as a decisive factor affecting the groundwater resources in the Yellow River Basin.Accurate calculation of the net groundwater recharge is of great importance for the rational develop-ment and utilization of regional groundwater resources and for regional hydrological cycle.At the point scale,equipment such as lysimeter can be used to directly monitor groundwater recharge,however,it is difficult to use this method to obtain the groundwater recharge at the regional scale.This calls for a simple method to quantify groundwater recharge at the regional scale.In this study,we proposed a new method to calibrate remote sensing data and estimate the multi-year groundwater recharge at the regional scale.We applied this proposed new method to the Taigemiao mining area in Xinjie,Ordos Basin,located in the middle reaches of the Yellow River.Based on the screened multi-source precipitation data and the corrected evaporation remote sensing data,we cal-culated the accurate mean annual net groundwater recharge in the mining area.The Hydras-1D numerical simu-lation based on measured data further verifies the effectiveness of the proposed evaluation method.The result in-dicates that the precipitation data from TPDC is more accurate in term of reflecting the spatial distribution of pre-cipitation in the study area.The MOD 16 remote sensing data underestimated the actual evapotranspiration in the mining area,which is 1.41 times of the MOD16 data.The mean annual net groundwater recharge ranges from-65.70 mm to 73.93 mm and the net groundwater recharge of more than 80%of the area ranges from-30 mm to 30 mm.The groundwater recharge estimated by the new method is consistent with the numerically simula-ted results based on the measured data,indicating that the method can be used in the prediction in areas where there is lack of surface runoff or detailed observation data of surface runoff.关键词
