A recharge assessment method combining daily soil moisture balance and well hydrographs was adapted. Its applicability to Canadian climatic conditions was tested in the Portneuf deltaic sand unconfined aquifers, where well hydrographs have been recorded at four sites for more than 10
years. Recharge from soil moisture balance is converted to changes in groundwater level using specific yield Sy and hydrograph recessions are considered, thus providing a synthetic groundwater level. Adjustments of hydrologic parameters allow the match of synthetic water level to well hydrographs.
This approach efficiently provides representative recharge estimates for unconfined aquifers.
