For recent years Land Use in DPS Way Sekampung has been changing in function for a gradual speed which is from 1995, 1998, 2000 and 2005, it has made a significant change in transformation of physical properties such as flow properties run-off coefficient (C) and amount of flow rate which is available or flood flow rate, and this changing has made scientist worried. Transformation value analysis run-off coefficient (C), according land use from 1995, 1998, 2000 and 2005, shows that each value in those years are 0.5, 0.58, 0.6, 0.6. Based on value of C the . sensitivity of transformation not significant or not sensitive (2.3% - 4.11%). Although those value transformations of C is not sensitive but it followed by available flow rate that is sensitive that is 3.20 – 43. 16%. Return periods of changing in land use which is in a short term (2 – 5 years) has brought a sensitive impact to amount of flow rate whether available flow or flood flow rate.
