Water balance in urban drainage includes rainfall, runoff and infiltration. Rainfall, Runoff and infiltration are hydrology system units. They are processes which happened together; when rain falls, water will flow overland as runoff and the water that is lost infiltrates into the ground. The occurrence will involve several parameters, variables and treatments. Because the infiltration rate needs to be inquired from rainfall and runoff processes, the experiment was done using soil media with soil density and landslope variation. Meanwhile, the tool used for this experiment is Advance Hydrology of Rainfall Simulator. To determine the infiltration rate model, Horton's and Kostiacov's formulas were used. A positive correlation (R2 = 0.91) of results for Horton formula was found, and a positive correlation (R2= 0.813) was found in Kostiakov formula, demonstrating that the Horton and Kostiakov formulas were comparable to the observation of infiltration rate. Based on the observation result in laboratory, landslope and density are influential variable for infiltration rate. Infiltration rate will get smaller in the same density with increase landslope variation and it will also get decrease when soil density get higher. In contrary, decreased soil density creates increased infiltration rate.

Abstract


Water balance in urban drainage includes rainfall, runoff and infiltration. Rainfall, Runoff and infiltration are hydrology system units. They are processes which happened together; when rain falls, water will flow overland as runoff and the water that is lost infiltrates into the ground. The occurrence will involve several parameters, variables and treatments. Because the infiltration rate needs to be inquired from rainfall and runoff processes, the experiment was done using soil media with soil density and landslope variation. Meanwhile, the tool used for this experiment is Advance Hydrology of Rainfall Simulator. To determine the infiltration rate model, Horton's and Kostiacov's formulas were used. A positive correlation (R2 = 0.91) of results for Horton formula was found, and a positive correlation (R2= 0.813) was found in Kostiakov formula, demonstrating that the Horton and Kostiakov formulas were comparable to the observation of infiltration rate. Based on the observation result in laboratory, landslope and density are influential variable for infiltration rate. Infiltration rate will get smaller in the same density with increase landslope variation and it will also get decrease when soil density get higher. In contrary, decreased soil density creates increased infiltration rate.
