Description:

This study aims to investigate the rainfall-runoff relationships and the main controlling factors affecting it using microscale wadies in Wadi Kafrein/ Jordan. Micro scale wadies are monitored using automatic pressure transducers and tipping bucket rain gauges. This study showed that runoff generated in these micro scale wadies is affected mainly by the rainfall intensity and duration, additionally; the land use play a significant role in this process, as cultivation and vegetation captures most of the precipitated rain. The altitude doesn’t seem to have a direct impact on runoff generation. The annual area rainfall average over Kafrein catchment is 411 mm/year, but the precipitation during the study period was found to be under the annual average by 40-45% in the winter year 2007/2008 and 67% until 18.02.2009 for the winter year 2008/2009. Consequently no runoff was generated in most of the micro scale wadies.
