Abstract
The effect of land-use exchange not best provide a few advantage to network but can also motive hassle, particularly: erosion, sedimentation, flooding and other. Erosion will reason silting of reservoirs, reducting irrigation channel capability, and disrupt electric power technology structures. excessive erosion, flooding inside the wet season no longer simplest have a poor effect on the biophysical components of natural assets and the environment however also the social aspects of the monetary effect on the community. several instances of adjustments in land use in a few watersheds in Indonesia is presented with a discussion of the causal courting of hydrological elements, mainly regarding the sporting ability of the watershed and the frequency of flooding. Hydrology and run off characteristics of a number of number one rivers in Indonesia (Java) supplied by way of using of land that growth timely. related with that case the studies could be taken. The objective is, to analisys affect of land use exchange to hidrological factors. at Mahat Hulu watershed, placed in the Lima Puluh kota district that 15 years antique (1995-2010) deforestation has taken significantly. In 1995 Watershed has woodland place approximarely 50.nine% and in 2010 decrease into 28% or from 14523 ha (1995) decrease to 7981 ha (2010) however blend garden increased from 17.1% (1995) to 43.8% (2010) or 4889 ha (1995) to 12508 ha (2010), therefore, which include runoff elevated, flooding, and drought in the course of the dry season, high erosion and sedimentation as well as a decline in productivity and earnings of farmers. In this case, special component that research, were the have an effect on of land use adjustments on the hydrological components along with coefficient of annual and seasonal runoff, and fluctuations. The method used quantitative and multiple regression check. result of evaluation are deforestation will increases coefficient run off, and fluctuations discharged. Coefficient runoff from 20% within the 1999-2002 to 24% in 2007-2010 and fluctuation of discharged (KRS) additionally extended from 2.four-five.5 (1999-2002) to five.9-10.7 (2007-2010) indicating DAS is critics. results of a couple of regression test showed a near correlation among the variables (0.nine) the method is C (%) = 975 - 11.2 htn - 15.three kbn cpr - 10.nine smk blkr + zero.forty three tgln dan R-Sq = 42.4%, for the stepwise regression test showed that wooded area area affect to run off. it is able to be showed from the equation is CRO = 31.5 - zero.370 htn, , R-Sq = five.3% Its mean, run off will extended cause by using forest location decreased. Keywords--- Hydrology, Erosion, Sedimentation, Runoff
