| Summary: | Infiltration is an important part of the hydrological cycle that describes the
movement of water from the surface into the soil. Two main factors that influence
infiltration include rainfall intensity and Antecedent Moisture Content (AMC). The
North Bandung area has diverse geographical and hydrological conditions that can
produce different infiltration and runoff processes. Therefore, this study aims to
determine the effect of various rainfall and AMC conditions on infiltration in
Cigadung.
The data used in this study are the research data of Hutasoit (2001) and BMKG
climatological data. The methods used are rainfall - infiltration model
configuration, model verification using Root Mean Square Error (RMSE) and
Nash-Sutcliffe Efficiency (NSE), scenario simulation based on the combination of
rainfall intensity with AMC, and analysis of the results of scenario simulation. The
results of this study show the influence of various rainfall intensities and AMC
conditions on infiltration in Cigadung. The amount and rate of infiltration
decreases as the AMC value increases under the same rainfall intensity conditions.
While under the same AMC conditions, the amount and rate of infiltration will be
higher as the rainfall intensity increases. |
