Abstract

Improving development usually change pervious to impervious land. The change concequence increasing surface runoff. Increasing surface runoff can be flood risk. Infiltration unit used to decreasing or delayed discharge surface runoff so able flood risk. Research infiltration process performed to prepared unit model made for wood dimension 100x100x100 cm3. Unit mentioned involve gravel-sand layer, precipitation pipe, and subdrain pipe. Unit model with two parameter that is vacuous land and (Mk) with vegetation (Mt). Input data for discharge Qb=0,44 liter/second, and Qk=0,24 liter/second. Data take discharge infiltration, time, height pond, and height water layer. Result research get for Qb = 0,44 liter/second with (Mk) by average decreasing 0,28 liter/second (Mk) during 28 menit and 0,21 liter/second (Mt). Whereas dewatering process during for 37 menit (Mk) and 29 menit (Mt). Keywords : surface run off, infiltration, model
