Comment on 'Distributed Recharge Estimation for Groundwater Modelling Using WETSPAA Model-Gaza Strip, Palestine' by Adnan M. Aish, O. Batelaan and F. De Smedt

摘要

Groundwater recharge is an important component of water budget for any catchment. Quantification of recharge from rainfall is a big challenge for hydrologists, as there is no accurate and robust method to rely upon. Different methods can be found in the literature Xu and Beekman (UNESCO IHP Series No. 64, 2003), but the selection of the appropriate method depends on site characterisation and data availability. This short communication discusses the paper "Distributed recharge estimation for groundwater modelling using WETSPAA model-Gaza Strip, Palestine" by Adnan M. Aish, O. Batelaan and F. De Smedt, and the resulting groundwater recharge amount. A comparison of recharge amount and spatial distribution resulting from the paper and other studies from the literature has been made. This comparison shows that the resulting rainfall recharge of Aish et al. (Arab J Sci Eng 35(1B): 155-163, 2010) in some areas is almost double that found in literature.
