The water exploitation index plus (WEI+) aims to illustrate the percentage used of the total renewable freshwater resources available in a defined territory (basin, sub-basin, etc.) for a given time step (e.g., seasonal, annual). The WEI+ is an advanced version of WEI with geo-referenced information. It quantifies how much water is monthly or seasonally abstracted and how much water is returned after the use to the environment in basins. The difference between water abstraction and return is regarded as water consumption and defined as water use.
