| Abstract | ||||
| New methods and earthen practices for rain-runoff water harvesting under sloping areas conditions to transform it from catchment areas into targeted areas at the same site and time to maximize the benefit from water runoff and store it in the same area for future cultivation to raise the productivity of water harvesting and optimal exploitation of a unit area by dividing these areas into several micro-catchment areas which were formed in different shapes by creating earthen barriers. The field experiment was applied at Wadi El Raml, Matrouh Governorate in the winter season of 2022/2023 under the following treatments: - three slopes (5, 8, and 13%) -(normal and compacted catchment area) and two shapes of micro catchments (W and reciprocal triangles). The results showed that treatment T11 which comprised a high slop of 13% with compacted catchment area and W shape for the divided micro-catchment achieved the highest values of runoff 7.7 m, runoff productivity 0.32.39 m3.fed-1 and water saving 0.279 liter.tree-1 respectively, while traditional treatment T0 and T2 which comprised the low slope of 5% with normal catchment area and triangle shape recorded the lowest values. In general, compacting high slope catchment areas and dividing them into micro catchments increases the productivity of water runoff harvesting and water saving for the target area. | ||||
