Prediction of Seawater Intrusion in Laizhou Bay Area under Groundwater Pumping Activities

摘要

With the rapid development of society and economy in China, the demand for water resource is increasing with industry and agriculture activities. Due to the excessive exploitation of groundwater resource, and global climate change, the seawater intrusion had arisen at some coastal areas in China. In addition, the sustainable developments of local society, economy, ecology and environment are influenced by the harms caused by seawater intrusion. In this study, a typical seawater intrusion area in Laizhou Bay is used, and the numerical simulation model is constructed by using the code SEAWAT4. The temporal and spatial characteristics of the development of seawater intrusion is analyzed by considering two scenarios, one is the groundwater pumping keeps at current level, the other is the groundwater pumping increases by 50%. Based on the prediction results, some prevention and treatment measurements have been proposed for current seawater intrusion.
