Abstract: | In this paper, we describe the development of a simulation framework for allocating water from different sources to meet the
environmental flows of an urban river. The model permits the development of a rational balance in the utilization of storm
water, reclaimed water from wastewater treatment plants, and freshwater from reservoirs with consideration of the limited
capacities of different water resources. It is designed to permit the full utilization of unconventional water sources for
the restoration of river water quality by increasing river flow and improving water quality. To demonstrate practical use
of the model, a case study is presented in which the model was used to simulate the environmental water allocation for the
Liming River in Daqing City, China, based on the three water sources mentioned above. The results demonstrate that the model
provides an effective approach for helping managers allocate water to satisfy the river’s environmental water requirements. |
