Environmental Restoration: Microcatchment Water Harvesting
To determine expected yields from microcatchments three rainfall characteristics must be evaluated: the average annual rainfall, peak rainfall intensity, and the minimum expected annual precipitation. Consideration ... basin can be estimated. Microcatchments are of course only effective when rainfall is sufficiently intense to generate surface flow. To improve catchment efficiency under ...
