Abstract


Accompanied by social and economic development and human resources development and utilization activities unreasonably out now Weihe River saltwater intrusion disaster in the region , which greatly damaged the local social , economic and ecological environment has seriously hampered the region 's socio-economic sustainable development. This paper analyzes the study area, saltwater intrusion and groundwater dynamic variation mechanism on the basis of scientific and feasible saltwater intrusion on dynamic monitoring network monitoring tools and the layout are discussed, and preliminary design of a dynamic monitoring system for saltwater intrusion . Full mainly includes three parts: First, the development of saltwater intrusion zone changes and groundwater dynamic law analysis . Since the study area fourteen years of continuous drought, caused by rapid economic development of the sharp increase in water demand , a large number of over-exploitation of underground freshwater, saltwater intrusion induced serious development . Through the saltwater intrusion zone groundwater table dynamics and groundwater chemical type and chemical composition analysis of the dynamic changes , we can fully understand and monitor the dynamics of saltwater intrusion zone developments and trends . Second, the layout of saltwater intrusion monitoring network . Based on the study area, the water supply and demand balance analysis and groundwater , water quality and formation resistivity variation of brackish water interface research and analysis , in order to carry out dynamic monitoring saltwater intrusion has laid a theoretical foundation, but also pointed out the monitoring of the technical approach and accordingly constructed three -level monitoring system : ( a ) macroeconomic analysis and groundwater supply and water balance negative area change monitoring ; ( 2 ) groundwater levels , changes in water quality monitoring ; ( 3 ) the development and changes of geophysical saltwater intrusion monitored. Third, saltwater intrusion detection system preliminary design . To make saltwater intrusion monitoring information to the full, systematic and scientific management and analysis , and applied against saltwater intrusion problem, we constructed a database as the core of saltwater intrusion detection systems . The system uses an object-oriented program design be prepared by a number of forms , classes , reports, and a main menu composed by the Project Manager unified management of all program writing and debugging. Users can call the system via the main menu functions.
