The purpose of this research is to analyze the potency of land water in the post tectonic earchquake at Merapi slope in Klaten regency, Central Java. This research applies a survey method. The result of analysis is made based on the trilinier diagram, Stiff pattern, and the quality standard of drinking water. The collected data are in the form of land form, shallow land water data, suppressed land water, and well or spring. The results of the sesearch show that 1) the land form in Klaten is divided into four sets of landform, they are peak and slope of volcano, feet of volcano, fluvial palin under volcano, and a set of structural morphology. 2) The potency of land water can be tested based on the amount of land water and the quality of land water. The amount of land water in Klaten regency 260,502,274 m3/year or 727,618,722 liter/day. The amount of land water above is taken from free land water 73,301,436 m3/year, suppressed land water 34,138,520 m3/year, and land water taken from well or spring 153,062,784 m3/year. The quality of shallow land water in Klaten regency is proper to consume. 3) The distribution of upland water potency happens in the feet volcano land form, the potency of medium land water happens in the superficial of fluvial under volcano land form, and the potency of lowland water happens in the slope volcano land form and in the structural range of hills at Bayat subdistrict, 4) The tectonic earthquake gives serious effect toward morphological changes, land split, land subsident and the potency of land water in the fluvial plain of land form under volcano and structural range of hills in the area of Bayat subdistrict, and 5) In 2008, the needs of drinking water in Klaten regency is predicted around 1,164,000 people x 150 liter/day = 174,600,000 liter/day.

This research aims to analyse rain fluctuation and river morphology to flood concentration in Bengawan Solo River, Surakarta. The method of this research is field survey supported by secondary data analysis. The survey was conducted using GPS (Global Positioning System). The result indicates that high intensity rainfall in the research area happened during October till April. River flow in dry season generally decreased in accordance with the distribution of low rainfall (dry month). Whereas, river flow rates seen to increase along with the rainfall that occurs in the rainy season. Other result show that point 11-18 (location in Tanjung village district of Sukoharjo till Semanggi village district of Pasar Kliwon) very superficial which became impact of the river. The point represent floods concentration, therefore if there is rain with high quantity, the water will rise and overflow to surface, especially point 11, 13, and 16 (Tanjung, Kedunggudel, and Telukan village district of Sukoharjo). The processes that occurred at these sites are sedimentation, and lateral erosion (horizontal erosion).

This study aimed: (a) to determine the general water balance at the Upstream and Midstream of Bengawan Solo Watershed by using Thornthwaite-Mather model, and (b) to determine the fulfillment of domestic water demand in the Upstream and Midstream of Bengawan Solo Watershed. Prevailing climate change has affected the condition of water source in Upstream and Midstream of Bengawan Solo Watershed. One of the impacts was extreme fluctuation of meteorological water availability that might cause flood and drought. Survey was selected as the research method while descriptive quantitative method was used for data analysis. The findings indicated the difference between precipitation and corrected evapotranspiration (P-EP) at the Upstream and Midstream of Bengawan Solo Watershed was between (-11.19 mm) to (78.56 mm). The highest value was obtained by Bambang Sub-watershed and the lowest was Wiroko Temon Sub-watershed. Positive value indicated the water surplus while negative value indicated water deficit. Domestic water demand for local communities was in the range of 50,782,500 liters to 131,690,700 liters, and the level of water availability varied, namely fulfilled and unfulfilled.Â

Configuration of the earth surface is molded by the interaction of endogenous and exogenous forces. The outcome of the interaction usually has the shape of special charracter. Configuration charracter is then applied to grouping of more simple form called landform. It so happens that one of the landform function is to make geomorphology research more easier. Que of the earth surface configuration is molded by wind force the result of this activity is called the landform which is originally molded by wind process. There are two folds function of wind process i.l: erosion (= coracoid process and deposifronal force). Coracoid process usually takes place on vertical as well as horizontal plane. Coracoid on vertical plane will have the shape of yardang, while on horizontal plane has the shape of pillars, needless, and zenguen. It so happens that depositional wind will shape ripples, sanddunes, and loess.

In planning a spatial order in a territory , it is necessary to take acount of three aspects of natural resources, human resources, and living environment. Based on the reality, so it is necessary to think of two sides: potential human resources and environment and human resources. One of the resources that is absolutely needed by creatures is water. Concerning the spatial order, the water is greatly needed in a variety of life. As the other resources, the reserve of the water also get limited. Because of its limitation, it is necessary to control the potential water sources in a territory before determining a design of good spatial order. It means that in planning the spatial order must be based on the rule and regulation of preserving its resource.

As a natural resource land has a strategic position in various development progress mainly as an infrastructure and means of settlement. At present it seems that land demand is getting increase adjusts to population growth and development rate. In connection to this question land problem has a close linkage in clay mining to obtain raw material of brick and tile. Clay as a manufactured raw material is usually extracted out from soil of agricultural field. Apparently, the clay mining has much changed physical and non physical condition, among others; lowering of land surface, reduction of soil fertility, micro relief changes, area constraction of groundwater charge supply, and there will be a decrease of flora and fauna variation at the operation area of the clay mining.

This study is carried out in chacthment area of Bodri. The goals of this study are to kno the influence of economic social condition of population on the change of the kind of landuse and the influence of the change of the kind of landuse on the run-off area. This study uses survey method. The collected data are the economic social data of the population and the physical condition data in the research area. The result of the study shows that the economic social condition of the population in chatchment area of Bodri influences on the decrease of landuse. The decrease in landuse is 22.27% which used settlement, dry land cultivation (3.14%), yard (1.07%), plantation (0.44%), wet land cultivation (2.28%), embankment (0.25%), street and others (6.73%). The decrease in landuse causes peak discharge of Hydrograph in 1997, 1999, 2000, and 2001 increases respectively 87.32 m/second, 101.26 m/second, 58.37 m/second, 89.82 m/second, with each volume of direct flow 7.123.392 m, 6.011.604 m, 11.784.672 m, and 9.459.954 m. The run-off coefficient in 1992, 1997, 1999, 2000, and 2001 increase 7.7%, 13%, 19.8%, 23.2%, and 27.03%, with coefficient of annual flow 46.98%, 72%, 55.21%, 61,79%, and 75.55%. The increasing of the run-off coeficient and annual flow describes that the ratio both the discharge of maximum and minimum monthly flow becomes bigger. It means that in rainy season it will be flood immediately and in dry season it will be drought easily.
