Model Hubungan Hujan dan Runoff (Studi Lapangan)
Abstrak: This research present
the model study on the relation between rainfall pattern and surface run off flows of a small catchment
area. The influences of catchment area characteristics such as land use, soil
behavior, topography condition and other related physical condition was
investigated. Surface runoff flow and peak discharge assessment was done at
each sub catchment area by using Rasional method. Application of this model was
to make predictions about the large pattern and surface runoff flow discharge
on the channel modeling that occurs due to rain. Results of studies that have
been done on modeling the river flow showed that the variables that most
influence was the runoff coefficient based on land use and rainfall patterns
will affect other parameters such as the time the water flows from the
catchment area to the drainage chanel modeling and drainage characteristic.
Close agreement between model result and rasional method is shown on surface
run off flow and peak discharge. This inaccuracy could be minimized not only by
improving the model but also using a better data calibration, such as highly
correlated rainfall and river discharge data with catchment area land use
condition.
