Role of Water Resources in Determining Spatial Planning of Region
No full textIn 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

No full textThe objectives of this research were 1) to determine soil moisture regime based on rainfall and temperature data; 2) to make a correction of the first objective based on soil moisture surplus and deficit calulation; 3) to study the pattern of soil moisture regime distribution in the research area. The field sampling tehniques applied in this research was stratified proposed sampling. Landform unit was applied as strata. Soil depth and texture were considered during field soil sampling within the landform unit. Rainfall and air temperature data were analyzed using Newball Simulation Model (NSM) to determine a tentative soil moisture regime. The tentative soil moisture regime was corrected using calculation soil moisture regime of soil moisture surplus and deficit. The soil moisture surplus and deficit was calculated based on soil depth, soil texture, rainfall, and temperature data. The result of this research were 1) soil moisture regime estimated using NSM ranged from ustic to udic; 2) soil moisture regime corrected using surplus and/ or defiit alulation of soil moisture ranged from xeric to udic; 3) the pattern of soil moisture regime distribution in the reaserch area was not only controlled by the pattern of rainfall – air temperature distribution but it was also controlled by the pattern of soil – landform distribution. Under the some amount of annual rainfall, shallow and coarse texture soils have drier soil moisture regime than deep and fine texture soils

A concept of Surveying and Mapping Vulnerability and Flood Hazard (with Hydro-Geomorphological Approach)
No full textThe general event of natural process phenomena on lowland areas is flood as an effect of the overtooping stream water over natural levees and inundate the area of surrounding the river. Most of the lowland surround the rivers is used by man for settlements, agriculture land, high way, and other activities to support their life intensively. Therefore flood is not only the physical phenomena but also a socio – economic phenomena. One of the way to understand the spatial distribution of flood prone areas an be done by means of survey and mapping of the flood susceptibility and hazard using an hydro- geomorphological approach. The fluvial landform units on the lowlands reflect the effet of the geomorphological and hydrological processes in the past. Therefore those phenomena can be applied to explain the recent flood characteristics such as inundation area, depth and flood duration, as well as flood frequencies and sources of floods. This explanation can be used as the starting point of the existing information which an be used as a basic survey and mapping of the flood suspectibility and hazard. The exiting of the interaction between man and natural event (flood) information, can also be applied as a fundament to define the hazard levels of every landform units own flood susceptibility levels
