Short summary
Most farmers' fields do not have data on runoff while soil and rainfall characteristics differ from those experienced at fields where experiments could have been done. This study found established that information from experimental fields can be used to determine the soil moisture benefits of rainwater harvesting by contour ridges using a combination of fuzzy logic techniques and an understanding of the processes taking place. The method developed can be used to help determine suitable sites.
