Abstract: Tarim River is the longest continental river in China, and is essential to the oases in the watershed and of the "Green Corridor" in its lower reaches. The Tarim River watershed is characterized by the arid climate and the vulnerable ecological environment. This paper develops the models of one-dimensional unsteady current of groundwater movement in the vicinities along the river channel of stream water transportation for the "Green Corridor" in the lower reaches of Tarim River based on the hydrogeologic conditions of the aquifer and the practical recharge to the shallow groundwater during the stream water transportation to the stream water cut-off river section at the lower reaches of Tarim River. The models are solved by transforming the boundary conditions of both discharge of stream flow and the groundwater level during the stream water transportation. The status of the groundwater rising is analyzed by using the models under the intermittent stream water transportation to the stream flow cut-off river section at the lower reaches of Tarim River. The results can provide the theoretical bases for the quantitative evaluation of the ecological benefits and the policy-making of the stream water transportation to the lower reaches of Tarim River.
