Flow Algorithm

This paper describes recent developments related to a new return flow algorithm built into the Water Resources Management Model (WRMM) of Alberta Environmental Protection. An earlier return flow allocation method which was used in the WRMM did not always give satisfactory results. It was essential to fix this problem, since correct modelling of the return flows in overall river basin management is of crucial importance. The new return flow algorithm offers more reliable return flow allocation without detrimental effects on the overall model solution. This model is a major river basin planning tool in western Canada used to analyze responses of a river basin to varying operating policies or structural developments. It is a simulation model with a nested optimization subprogram. As a deterministic, steady state, and surface water allocation model, it normally relies on the estimates of natural flows and water demands throughout the river basin. The WRMM can provide quick simulations of any river basin with any number of components within a microcomputer environment. The model is used in ongoing river basin management studies in Alberta and other western provinces in Canada. Key words: water management, computer modelling, simulation, optimization, irrigation.

This paper puts forward and studies the concept, features as well as regulation process of real-time dispatch of basin water resources. The real-time regulation of basin water resources features temporal regulation system of multiple time-step nesting, dynamic balance regulation system of self-adapting demand-supply, dynamic information-based feedback regulation system, and three-element regulation system in combination of reservoir dispatch, river reach water distribution and flow forecast control. With example of lower Yellow River reaches below Xiaolangdi, a real-time regulation model of water resources in river basin with multiple time-step nesting and scrolling-amendment has been developed. The developed model has been put into actual practice and resulted in the safety of water supply and avoid of dry-up in consecutive low flow yeas of Yellow River Basin.
