- 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
