Abstract

The water demand increases in line with the growths of population, industry and business, but the water availability is ascertained to satisfy those needs continuously. Therefore, it is necessary to analyze water availability in a specified watershed integrated with various aspects in hydrology. The objective of this study were (1) to identify of landuse at Prumpung watershed,(2) to determine water availability in Prumpung watershed by analyzing the relationship of rainfall and river discharge using the Soil and Water Assessment Tool (SWAT) and (3) to influence government policies relation with urban planning of Tuban Regency. The watershed is located in Tuban Regency and based on urban planning of Tuban Regency 2012-2032 which is covering 22,319.14 ha. Input data were Digital Elevation Models, land use, and soil map. The procedures were including collection and process of climate data, trend analysis of water availability, discharge measurements, discharge analyze and calibration using SWAT. The results of existing landuse showed that the minimum water discharge was 0.338 m3/s to the maximum 5,945 m3/s with groundwater availability was maximum until 3,070 mm on July to September 2014. SWAT has generated 27 HRUs that described the spatial condition of the whole watershed. Calculated discharges with SWAT compared to the measured discharges having The NashSutcliffe Efficiency (NSE) of 0.77 and correlation coefficient of 0.79. Conservation scenario has been conducted at several landuses for water availability and based on conservation area. The results showed that the minimum water discharge was 0.334m3/s to the maximum 4.842 m3/s with groundwater availability was maximum until 3,140 mm. There were no significant change of groundwater based on urban planning and scenario at Prumpung watershed, Tuban Regency.Identification of Prumpung watershed produced relatively small water discharge compared than water demand based urban planning of Tuban Regency. A plan of water management for exploiting of high rain fall in rainy season will contribute in consideration of the appropriate water supply/demand balance in dry season.

Abstract

Estimation of surface run-off in karst watersheds has not been widely carried out and the estimation method is generally developed for non-karst watersheds. This study aims to analyze the accuracy of estimation of river discharge at the outlet of the Karst Biringere Sub-watershed using the modified Soil Conservation Service Curve Number (SCS-CN) method and analyzed the impact of land use change on river discharge at the outlet of the Karst Biringere Sub-watershed. Modification of the SCS-CN method in estimating direct flow at the outlet of the Beringere Sub-watershed is influenced by the similarity of rainfall and direct flow fluctuation of river discharge. The modified SCS-CN method provides satisfactory direct flow estimation when rainfall with observed direct flow of river discharge forms a linear relationship with a strong correlation. Changes in land use with reduced forest cover into mining areas result in increased run-off and reduced storage, the larger the forest land becomes mining areas, the greater the increase in run-off and reduction in storage. Reclamation of the former mining area to be a forest reduces run-off and increases water storage.
