Abstract

This research was conducted in Kali Premulung Watershed which is one part of Bengawan Solo Watershed. This study aims to determine how much land use change and its effect on the coefficient runoff and peak discharge in Kali Premulung Watershed at 2006 and 2014. The research method used is the method of secondary data analysis. Secondary data obtained from Government Institutions in the form of rainfall data from 5 stations within 10 years, also map of soil type, slope, river network and land use. The analysis used in the form of descriptive analysis on the spatial distribution pattern of land use and its effect on the runoff coefficient in 2006 and 2014. From the research results show that Kali Premulung Watershed has an average rainfall area of 101.84 mm in 2006 and 60.78 mm in 2014. Changes in land use that occurred between 2006 to 2014 ie water pool decreased as much as 0.13 km2, gardens increased as much as 0.22 km2, settlements increased by 6.63 km2, grass decreased by 0.73 km2, rice fields decreased by 5.38 km2, rocky ground increased by 0.17 km2 and mooring area decreased by 0.75 km2. From the scoring results using the Cook Method in 2006 the runoff coefficient of Kali Premulung Watershed has a coefficient of runoff of 42.75, while in 2014 has a runoff coefficient of 43.14. It shows that the effect of land use change on the increase of runoff coefficient. The results of the peak discharge calculation using rational method in 2006 with rainfall intensity of 7.08mm / hour provides a peak discharge value of 64.52 m3 / sec, while in 2014 with rainfall intensity of 5.05 mm / hour provides the value of the discharge peak of 46.38 m3 / sec. An increase in runoff coefficient of 0.39 affects the increase in peak discharge amounts of 0.71 m3 / s if the intensity of rainfall in each year is calculated based on the average rainfall intensity during the research period which is 7.76mm / hour. However, due to the tendency of direction of rainfall intensity trend that decreased from 2006 to 2014, causing the estimated amount of peak discharge decreased by 18.14 m3 / sec.
