Abstract

The objectives of the research were (1) to explore theories related to landscape principles and models for enhancing water retention, (2) to study physical characteristics and which model is appropriate for urban area, and (3) to analyze collected data for further summary and proposing the suggestions for area improvement. The results showed that Prawet District, Bangkok is geographically characterized as a lowland that absorbs water. In the past, it had many number of brooks, canals, and spaces without severe flood problem and flood caused economic damages. Later, the growth rate exceeds the urban planning's acceptable standards of land use and public utilities, drainage measures, and flood protection. The main causes include deteriorated natural drainage conditions, constructed roads and buildings that obstructs water flow, environmental destruction, especially urban areas where housing development projects have been increasing. In addition to natural causes, human-made causes result in flood in urban area. After exploring the setting of a case study, physical data were gathered and it was found that the land invasion along two sides of the canals and wastes in the canals negatively affect the quality of life of the residents and also lead to repeated floods, especially, floods around Srinakarin road and housing estate area.
