Rizhao Coastal Area Of Shallow Groundwater Control Research

Groundwater is an important part of water resources is a valuable resource for life on one, it is a complex ecological system composed of a sensitive factor, the change will often affect the natural ecological environment of the system equilibrium. Excessive exploitation of groundwater will lead to a series of geological environment, on people's lives in different degrees. How rational exploitation of groundwater resources and scientific management, is directly related to the harmonious development between man and nature issues.Rational development and utilization of groundwater resources, scientific management, mainly administrative, economic and technical measures. Administrative measures by formulating a series of laws and regulations and management of groundwater exploitation shall limit the economic measures listed are subject to water resources through fee collection and control groundwater exploitation and irrational use of technical measures by regional groundwater resources investigation and assessment, development of optimal exploitation of groundwater program to achieve optimal exploitation of groundwater resources. This paper is the perspective and technical measures to optimize water resources exploitation Bu program, through the groundwater flow simulation, comparative analysis of the various underground mining program to protect the geological environment as the starting point of optimal exploitation of ground water work on the study program.This article is based on groundwater mining technology proposed to optimize the program procedures and methods, mainly including the exploitation of groundwater optimization model and optimization program of groundwater exploitation. First, the study area by building a multi-simulation model of groundwater flow, including three-dimensional conceptual hydrogeologic layer model and numerical simulation of mathematical models, to lay the groundwater exploitation Optimization basis of the analysis. Firstly, the software module to establish a study area of three-dimensional model of the hydrogeological layer so as to facilitate the accurate and comprehensive generalization of the local hydrogeological conditions provide a good platform to establish the hydrogeological conceptual model, the established mathematical model of the study area through the correction method, the model is identified, then select a number of time the water level in the measured data verify the model was verified to validate the establishment of the hydrogeological conceptual model and mathematical model of rationality.Validated simulation model of groundwater flow calculation program developed groundwater exploitation to different mining groundwater flow field under the program to predict the trend of water level in the model calculations the changes and the trend of flow of groundwater exploitation in all programs Science and rationality was analyzed and evaluated and reached the groundwater exploitation optimization program, so as to study the rational development and utilization of groundwater for reference.
