Examining the Impact of Daily Mean Intensity of Precipitation on Direct Runoff in Catchment Areas
Abstract
This study used a descriptive-evaluative method of research to explore the factors influencing direct runoff and develop model equations for predicting a day ahead power forecast of mini hydropower plants. The research utilized data from the Hydroelectric Development Corporation (HEDCOR) on rainfall, runoff observation, and flow discharge, as well as catchment characteristics provided by the Geoscience Division of the Department of Environment and Natural Resources (DENR-CAR). Intensive variables were obtained from military maps digitized with AutoCAD software. The findings of this study provide valuable insights into the factors influencing direct runoff in catchment areas and contribute to the development of accurate power forecasts for mini hydropower plants. This study sheds light on the link between daily mean rainfall intensity and direct runoff in catchment regions. The findings indicate that the intensity of rainfall is an important element in influencing the incidence of surface runoff. When the intensity of rainfall is less than the infiltration capacity of the soil, there is no surface runoff because the earth absorbs all of the water. Surface runoff occurs when the intensity of rainfall exceeds the infiltration index of the soil. Furthermore, the study emphasizes the impact of different catchment area features on direct runoff.
