Abstract

The hydrological character of the rivers in Java has changed. The trend flow of upstream rivers in Java declined. Significance level of the trend decline in the upstream was large enough. This indicates that the basic flow (base flow) from these rivers has been reduced. The cause of the trend decline in river flow is strongly influenced by a combination of the effects of global climate change and the influence of anthropogenic. The influence of climate change is marked by decreasing annual rainfall. While anthropogenic influences include changes in land use, reduced water catchment area, increasing population pressures and settlements. To identify which factors are most influential between the two factors are very difficult to do because of limited data on land use change. Keywords: discharge, trend, climate change, landuse, anthropogenic

Abstract

Water supply for the domestics use of Central Java Province has been experiencing problems and challenging. With population of 35 million or 16% of Indonesia, it place the province as the third in national population. It have consequently, water need in the province is as such for use of domestics, irrigation/agriculture, industry, etc. Several counties within the province has experiencing water shortage. Particularly during dry season, defisits is inclining that results water use conflicts. Furthermore, conflicts occur not only in counties with water shortage but also in county with sufficient water supply. Conflict is generally triggered by weak management and allocation. This is a result of unlimited territorial sovereighnity of water resources and uncertainty of water rights. Unlimited territorial sovereighnity of water resource contain exclusive right to utilize tap water within the territorial right, in way that the territory hold the sole right to exploit the resource without compensation to neighbouring territory. Hence, water balance should be investigated better and comprehensively. Kata kunci: keseimbangan air, konflik, sumber daya air, Jawa Tengah.

Abstract

Flood that has occured in Jakarta in 27 January - 2 February 2002 was a result of heavy rain and impact of over discharge streams within its catchment area. Furthermore, occurence of low air pressure around northern Australia and Intertropical Convergence Zone (ITCZ) around Java Sea up to Banda Sea, has driven moists in the Asia into the area. Precipitation resulting flood is a return period about 1 to 1000. In Ciliwung watershed, mean rainfall of 142,5 mm/day and return period of about 100 years. This was bigger than mean rainfall during the period of 29 January 2002 about 110 mm/day that return period 200 years. Katakunci : hujan, banjir, periode ulang.
