Abstract

Bosten Lake is located in Yanqi Basin of Xinjiang. A working area in the southeast of China is influenced by the regulation of Bosten Lake, and the transitional zone of climate in the north and south of Xinjiang, forming a climate of large evaporation, dry and little rain, and groundwater is a very important fresh water resource. In order to find out the composition of groundwater resources in the working area, the groundwater steady flow model is established by using the data of borehole, well, pumping test and so on, and the groundwater resources in this area are evaluated. The groundwater exploitation mode in the simulated area is evaluated. The results show that: the exploitable groundwater resources in the simulated area is about 22.045 million m3/a. Changing the mode of agricultural water use under the existing groundwater equilibrium condition can effectively reduce the waste of groundwater resources.

Highlights

  • With the development of industry and agriculture and the improvement of people's living standard, the demand for water resources is rapidly expanding

  • The output of MODFLOW operation results is in a text file, and the output of the model is the total amount of each source sink term, which needs to be restored according to the method used in the input of the model data, and the composition of groundwater resources in the simulated area is obtained by calculation

  • Recharge resources: by using the parameters corrected by the numerical model, according to the average precipitation and the leakage of the flood current, according to the calculation results of the water balance in Fig. 9, the rainfall infiltration recharge in the studied area is 33.164 million m3/a

Summary

Introduction

With the development of industry and agriculture and the improvement of people's living standard, the demand for water resources is rapidly expanding. Numerical simulation of groundwater is a common method to predict and evaluate groundwater resources. It is necessary for people to reveal the laws of hydrogeology and evaluate and manage groundwater resources by establishing reasonable numerical models [1]. Based on the groundwater exploration project in the southeastern part of Bosten Lake, a series of parameters are obtained by collecting historical data of geological and hydrogeological work carried out in the early period, field investigation and pumping test. The stable flow model of southeastern region of Bosten Lake was established by GMS, and the groundwater balance was calculated during the simulation period [3]. The model can basically reflect the distribution and movement law of groundwater in the study area and provide scientific basis for the development and management of groundwater resources in this area
