Abstract

In the hydrogeological unit, quantity of water that replenishes groundwater beneath the water table, expressed in mm/yr. Recharge is usually calculated using hydrology balance, integrating information from precipitation, hydrology data, drainage, soil properties, evapotranspiration, etc. The result is a raster dataset in which each cell has a given value for the recharge of the aquifer. It can be calculate using HELP software, developed by the US EPA. The methods used to create the dataset are described in the metadata associated with the dataset. The dataset represent a raster in which each cell has a mean value describing the global annual recharge of the hydrogeological unit.

Process step

Sources

The datasets were extracted from all projects constituting this series.

Groundwater mapping projects.

The original recharge shapefile showed cells with recharge value of 0 mm/yr surrounded by uniform recharge value. The values of these cells were changed for the uniform value of the surrounding cells. To do thus, the cells were manually selected and the recharge value was changed by using « Field Calculator ». The recharge shapefile was then converted to a raster. The recharge values were modified from decimal numbers to whole numbers. To do thus, a new numeric without decimal field was added to the attribute table. The recharge values were added though ""Field Calculator"", requesting that the recharge values equal the original ones. The shapefile was then converted to a raster using the ""polygon to raster"" tool with a cell assignement type of Maximum_Area and a cellule size of 70.
