| Abstract: | Reliable field data for all hydrologic parameters are often unavailable for watersheds even for those intensively monitored. In the absence of reliable such data, verified mathematical relations for an area can be used for other areas with same hydrologic and climatic regimes. The objectives of this research were: 1) to assess the total runoff and sediment loss, and 2) to develop rainfall, runoff and soil loss relations for four prominent landuses (including degraded, pasture, forest and agriculture lands) in the Hilkot watershed (Pakistan). Four experimental natural runoff plots were established on the landuses (degraded, pasture, forest and agriculture land). The field study and data collection were conducted in the Hilkot watershed from 1999 to 2005. Regression analysis was conducted to establish relations among rainfall, runoff and soil loss for all landuses using. Regression analysis indicated good correlation with field data. |
