A new paper from AMGRAF UPGro Catalyst (which has continued with support from the REACH programme).

Walker, D. , Parkin, G. , Schmitter, P. , Gowing, J. , Tilahun, S. A., Haile, A. T. and Yimam, A. Y. (2018), Insights From a Multi‐Method Recharge Estimation Comparison Study. Groundwater. https://onlinelibrary.wiley.com/doi/10.1111/gwat.12801

Key Points:

  • A recharge assessment was conducted at a study site in Northwest Ethiopia (Dangila woreda)
  • 9 groundwater recharge estimate techniques were used with a total of 17 variations were applied to a shallow aquifer
  • These gave a wide range of values from 45mm/year to 814 mm/year
  • The most reliable estimates for reliable recharge are in the range of 280 – 430 mm/year, however the outliers to provide some useful information that helps understand the aquifer
