Abstract (English) :
Hydrological characteristics, such as water discharge or runoff, is related to actual land use and land cover at watershed area. Present information on land cover can also be used for many purposes, e.g., land evaluation project, environment, hydrological, regional planning studies. To obtain actual information on land cover could be used Landsat TM image. It has been widely used for land cover evaluation and mapping. This study was conducted by using Landsat 7 ETM + image (year of 2000) to evaluate the present condition of permanent vegetation (forest area) and non-forest area in the Wanogiri Dam Catchment Area (WDCA). The results indicate that 1) forested area at WDCA in 2000 covered 25 % and non-forested area covered 75 %; 2) Solo Hulu watershed has the widest forest area (54 %), followed by Wiroko (51 %), Unggahan (36 %), Keduang (26 %), Wuryantoro (23 %), Alang (12 %), and the smallest in Temon (11%); 3) Keduang watershed with young volcanic geologic formation has a significant ratio between % forest cover and runoff coefficient as 26 % and 26 %; 4) Temon and Wuryantoro watersheds with mix of old volcanic and limestone geologic formations give the ratio between % forest cover and runoff coefficient, of which the values of runoff coefficient (C) of both watersheds would be 1.4-2.5 times of each % forest cover; 5) Alang watershed with limestone geologic formation has a value of runoff coefficient (C) to be 1.3 times of % forest cover.
