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
