Detecting Water-Economic Interactions In Heihe River Basin Using Coupledgroundwater And Agent Model

Located in northwest China the second largest inland river HeiheRiverwhich is originated in the Qilian Mountains, flows throughAutonomous Region Qinghai, Gansu, Inner Mongolia It plays an extremely important position both in policy and in strategy. However, due to its natural conditions, geographical conditions, the ecological situation, hydrology and integrated governance and facing severe challenges, the Heihe River Basin water resources can not meet the middle and lower reaches of the basin with waterChinese government finally in August 2000 launched the implementation of national watershed scheme, put forward a new model of water allocation and water cycle call, but did not completely solve the problems.Based on the analysis, the use of Matlab and Modflowdetecting Water- Economic Interactions in Heihe River Basin using Coupled surface- groundwater and multi-agent modelThe basis of fully coupled surface groundwater on the establishment of basin water body model- economic interaction study successfully simulated depth, extraction, water runoff basin anhydrous transaction when other indicators, and compare the relationship between them reveals the whole river basin water basin have transactions under water users with water and transactions.Water trading enables water basin has been re-distribution, exploitation is shallow downstream water users increases, increase water users upstream and vice versa. While the water when the transaction due to its water-use efficiency is not high enough, low efficiency of upstream water users to reduce water use, or sell the water to get the best economic returns through water trading, water trading occurs in the case of water users always from the water Benefits Low transfer to high water-use efficiency of the user. These laws will provide decision support and management advice to governments and managers.
