|Title||Optimizing environmental water release decisions in river systems|
|Presenter||Simranjit Kaur (The University of Melbourne)|
|Session||Operations Research and Optimisation|
The ecological conditions of rivers across the world are getting deteriorated due to an increase in extraction of water to meet the increasing irrigation and human consumptive demands. To protect river ecology, Australia has introduced legal water rights for environment, where a parcel of water is allocated to the environment every year that can be released into the river from different storages/reservoirs associated with the river to maintain/increase the health condition of various species in the river. An environmental manager for a river system is responsible to make decisions around the timings, locations and volume of environmental water releases in order to gain maximum benefit to the river ecology. Complexity of these decisions gets escalated by several factors including the existence of a large number of species to protect (which can possibly have conflicting flow demands) and a limited volume of water availability for the environment. In this talk, we present a mixed integer programming based optimization tool that can assist environmental managers in making such complex decisions.
