Abstract
Groundwater is an important water resource and its management is vital for integrated water resources development in semiarid catchments. The
River Shiyang catchment in the semiarid area of northwestern China was
studied to determine a sustainable multi-objective management plan of
water resources. A multi-objective optimization model was developed
which incorporated water supplies, groundwater quality, ecology,
constraints. A calibrated groundwater flow model was supplemented by
grey simulation of groundwater quality, thus providing two lines of
evidence to use in the multi-objective water management. The response
matrix method was used to link the groundwater simulation models and
the optimization model. Multi-phase linear programming was used to
minimize and compromise the objectives for the multi-period,
conjunctive water use optimization management plan was able to meet
ecological, overall water deficit within the catchment.
