Abstract

The forest degradation rate reached 2,83 million ha every year. From the total forest area of 120,5 million ha, about 59 million ha were critical areas. Besides, the critical Watersheds ini Indonesia increased. The watershed conservation efforts had brought motivation to develop the erosion estimation technologies that could assist in solving the erosion rate estimation problems spatially. The study was carried out at Tilong Watershed, Kupang Regency of NTT Province. The results showed that the value of erosion rate in Tilong Watershed area with existing (year 2010) land utilization condition was 25.428,155 ton/year where the Tilong Watershed total wide was 4.948,75 Ha. Whereas the sediment potential was 7.319,524 ton/year. The Erosion Danger Level was 74,62 %. One of the assumptions why the land erosion rate was very high was because of the misuse of the land in that area. To control the erosion rate, focussed to the recommendation of land utilization direction that referred to The Soil Conservation and Rehabilitation Program (ARLKT) and building of 8 check dam. Meanwhile, the land utilization should notice The RTRW and the cooperation between local inhabitant and the government was needed indeed in the soil conservation and land rehabilitation efforts.Key Words : Erosion, Sediment, Check Dam, GIS

Abstract

Drought is a natural hazard which is characterized by the scarcity of water. Drought disaster management with non-structural approach through drought monitoring with drought spatial information in monthly drought index map and temporal information for each region in sub-watershed. The location of research is Upstream Brantas River Basin which is divided into 3 (three) sub catchments supplemented with 12 (twelve) selected rainfall stations capable of sending real-time daily rainfall data. The analysis of this drought uses Thornthwaite and Mather’s (1957) method, which is an index to inform the drought rate of a region by using water balance parameter. Result of study indicates that the biggest drought index is found in years of 1991, 1994, 1997, 2002 and 2008 (during the happening of El-Nino) from July to October. This high drought index seems following the decrease of the discharge at Gadang AWLR in those years.Keywords: Drought Index, Thornthwaite, El-Nino, Water Balance, Climate Change

Abstract

Infiltration process is one of the important processes in the hydrological cycle due to infiltration of determining the amount of rain water that seeped into the soil directly. This study aims to obtain mapping potential infiltration and recharge area. The approach used is KINEROS model, where the model was calibrated with field measurements using a turf-tec infiltrometer and tested with NSE statistical methods. Calibration results obtained after trial and error changes on three basic parameters in the model KINEROS, namely K (hydraulic conductivity of the soil), Gs (impulse capillary) and Por (porosity), also on the parameters of the Manning coefficient. After a change of 50% Manning coefficient and 75% value K, Gs and Por, test results obtained NSE = 0.460 which means that the model results are acceptable, and can be followed by a map showing the infiltration rate for and is used to determine the condition of the watershed Bodo.Key words: Infiltration, KINEROS, calibration.
