Our water auditing application offers a solution for water managers tasked with checking water permit compliance in irrigation. Where permits are usually introduced in an effort to regulate water use, systems to monitor compliance are often absent or ineffective. The satellite based water auditing application monitors the volumes of water used in irrigated agriculture on a regular basis. It then automatically checks this against the permitted volumes, flagging non-compliance. It is field specific, can be applied for large areas and even international river basins. This tool gives water managers facts to base their practices on and enhances the effectiveness of their operations leading to more equal water distribution across the board. The Water Auditing application is developed in cooperation with Hydrologic and is available via HydroNET, Hydrologic’s web portal.
