| dc.description.abstract | The study was conducted at some watersheds (Temon, Wuryantoro, Alang, and Keduang sub
Watersheds), in Wonogiri District. These four sub Watersheds are main river whose outlets go into
Wonogiri Dam. The study will calculate of water availability and the need of water for various uses at
four sub Watersheds. The Thornwaite and Mather method was used to calculate the of water availability.
The results indicate that : (1) The water availability at Temon Sub Watershed) 35.435.875 m3 and
the need of water per year sebesar 51.053.247 m3, the water minus 30,59% per year; (2) The water
availability per year Wuryantoro sub Watershed 17.788.417 m3 and the need of water per year
22.413.430 m3, the water minus 20,64% per year; (3) The water availability per year at Alang sub
Watershed 31.372.317 m3 per year and the need of water per year 69.566.500 m3, the water minus
54,90% per year; (4) The water availability per year geological at Keduang sub Watershed 438.527.889
m3 and the need of water per year 452.611.219 m3, the water minus 3,11% per year; (5). Watershed
having condition needs improvement especially an effective water resourcesplan, allocating, and distributing
of water according to priority establishment, e.g., water pond, revegetation with low evapotranspiration
potential, developing infiltration well, protecting water spring from disconcerting, and construction of
water reservoir. | en_US |
