Study on Ground Water Level & Water Balance Influence under Different Water Compensation Schemes of the Yellow River Delta
According to the study on factors of weather, hydrology, and geology of the Yellow River Delta, screen and identify three factors of river feeding, precipitation supplement and evaporation capacity which impact much on the Yellow River Delta ground water level, and establish reliable groundwater model in virtue of software Visual Modflow. Through simulating the status (selecting 2004), further define the influence degree of the river feeding, precipitation supplement, and evaporation capacity on ground water from the aspect of water balance. Seen from analysis on water balance in 2004, groundwater cannot maintain balance and supplement capacity cannot meet the evapotranspiration demand of vegetation, therefore it is necessary to adopt man- made water compensation to improve the water balance of this region. According to wetland composition while building the nature reserve of the Yellow River Delta wetland and its present actual situation, define the water compensation area and preliminarily select water compensation scheme, which are 278 million m3, 349 million m3, 396 million m3 respectively (proposed) and study the influence of different water compensation schemes on ground water level and water balance. Study and analysis shows that there still exist deficiencies in the present water compensation scheme. Deeper study on water compensation schemes is needed to improve ground water situation.
