Development of numerical software tools and procedures to help staff estimate the impact of groundwater abstractions on river flows.
The programme is entitled “Impact of Groundwater Abstractions on River Flows” (IGARF). The first phase of this programme has been completed, and a software tool has been developed by Environmental Simulations Limited which uses simple analytical solutions to the equations describing river-aquifer interactions, implemented in a user-friendly Excel spreadsheet. The second phase of the programme seeks to produce an approach and tool that has better capabilities to represent realistic river-aquifer interactions than is possible with the IGARF I tool. The contract to develop this tool has been awarded to the Water Resource Systems Laboratory (WRSRL), Department of Civil Engineering, University of Newcastle upon Tyne, and work started in December 1999.
