Effect of Water Allocation of the Heihe River and Water-saving and Rebuild Project on Ground Water Level of the Middle Reaches of the River——A Case Study in Ganzhou District of Zhangye City
Dynamic transformation of groundwater level reflect effect of the climate、the irrigation and the geology.In order to study the effect of water allocation of the Heihe river to the ground water level,the monitoring data and the prediction data of one area during the same period were compared and analyzed.The method not only can evaluate true effect of water allocation of the Heihe river and water-saving and rebuild engineering,but also provide useful advices for next project.
