    Abstract

    The floods and inundation phenomenon always happened every year at rain season in a considerable part of Indonesia region, especially in urban area. The event occurs also in Surakarta city, where flood and inundation almost occurred when the rainfall intensity are quite high. This is due to rapid increased on land use change in Surakarta from open space area to development area. Based on that reason, this research is carried out to analysis the influence of land use changes in North-West region of Surakarta city (i.e., watersheds of Gatak area) on increasing of surface runoff in which the discharge has been flowing down into Surakarta city. The result show that land use of Gatak watersheds has been rapidly changed from year 2001 to 2007. During this period the land use changing is about 9,95% from the catchment total area of 1152,97 ha. The land use change caused increasing surface flow coeffecient (C), from 0.286 on 2001 to be 0.307 on 2007. Moreover, analysis of maximum discharge by using Rational Method and also field observasion showed the same trend, where in the simimilar rainfall intensity events between year 2001 and 2007 results greater number of discharge flow in 2007 than those in 2001. The increasing of discharge is also showed by occurring of flood and inundation on the recent years, compared on early year 2000 which was no flood happen on that time. Keyword : Land use change, runoff coefficient, flood and inundation
