The Shiguanhe river basin is subjected to strong human pressure; it faces severe water management problems, concerning flooding and irrigation in particular. This basin is a complex hydraulic system, including many dams and irrigation channels. Here, an attempt at developing a complete water resources assessment is proposed. The tools for this assessment are described: they concern both hydrological modelling and remote sensing. A specific methodology has been adopted to represent the irrigation, in a three-step approach. Firstly the irrigation outside the basin, secondly the irrigation inside the basin, and lastly the rice farming techniques impacts on the basin's hydrological behaviour are taken into account. Finally, we obtained a good representation of the major hydrological processes taking place in such a complex human-modified system.
