Abstract

Palembang is a river city that its land is dominated by lowland. In its initial development, the settlement was built based on adaptation to the nature of lowland area such as riverbanks and marsh. Along with the increasing population, the settlements including housing area has spread from landed to lowland area. Many housing areas are developed on the reclaimed low lying land. The problem has arisen when the flood happened in this housing area. The flood has affected residents’ well-being and image of housing area as elite estate. The aim of this paper is to evaluate the preference of residents on the environment of housing on the reclaimed lowland area. To achieve this aim, the study examines the change of preference of residents on three aspects; housing attributes, renovation and infrastructure quality. The study used quantitative method. Data were collected by survey questionaire from 150 residents. Data were analyzed by using factor analysis. The results show that there is a change ofresident preference from housing attributes to the environmental aspects, particularly the quality of drainage system and the availability of water catchment area. This change appears after the flood happened recently in their housing area as an impact of the reclaimation. Study concludes that the water management system is the aspect for controlling the inevitable city development at lowland area.

Abstract

The watershed delineation process is needed and has an essential role in various water resource projects. This study aims to examine the GIS processing function embedded in the latest HEC-HMS software version 4.4 for the delineation of watershed and elements of the hydrological model. In comparison, watershed delineation was also carried out by using ArcGIS software. The area of study is the Bendung subbasin located in Palembang City, where terrain data used is a National DEM data with a spatial resolution of 8 m (0.27 arc-second). The results showed that the boundaries and area of the watershed produced by HEC-HMS 4.4 and ArcGIS showed the same characteristics. The river network produced by the two software shows a slight difference even though the flow patterns are similar. It shows that the level of accuracy and quality of the delineation produced by the HEC-HMS 4.4 is excellent. Besides, elements of the hydrological model can be generated automatically which is not found in previous versions. It allows users to more quickly simulate detailed hydrological models with a large number of elements. Therefore, the use of GIS functions in HEC-HMS 4.4 must be encouraged for various analysis purposes in water resources projects.
