Summary

A water balance study in Yemen's mountainous region, with average annual rainfall ranging from less than 50 mm to over 800 mm, was conducted to develop statistical and rainfall-runoff models. The study revealed an unusual pattern of relationship between mean rainfall and runoff, suggesting that runoff coefficients do not decrease to zero as rainfall approaches zero, but rather reach a minimum value. The country's topography, geology, and climate, including the Red Sea Convergence Zone and the Intertropical Convergence Zone, affect the hydrology. Unique land use practices, such as bunding and terracing, permit rain-fed agriculture and delay runoff during intense storms, reducing total runoff and storm runoff.
