Abstract


Water flow rate is influenced by slope and thickness of the water running down the slope. Water erosion process which is triggered as follows: precipitation that fell on the soil surface are absorbed by the absorption capacity of the soil volume exceeded rainfall quantity, water will accumulate in micro-depressions. If rainfall continues to fall, stretches of water formed unite and form a continuous film of water begins to flow as rills or streams. Soil erosion is caused mainly by: relief, climate (air temperature, wind, rainfall, atmospheric pressure, humidity, duration sun radiation, cloud cover, weather phenomena), soil, rock soil formation, vegetation and land use. Creating GIS spatial analysis model required the following steps: creating the database, appropriate spatial modeling, model validation to quantify the risk.
