The Design Efficiency of Stormwater Management Area for Development the Urban Construction Project.

Abstract

Nowadays, Nan becomes one of the tourist provinces that raise more popularity than in the past; therefore, there is a number of improvements and the expansion of urbanization. Accordingly, the development plan for the specific area, Phu Phiang is established to be the initial area to support the amount of tourism and to develop the quality of local people. It is located at Nong Nam Krok which was formally used as the area to prevent a flood of Phu Phiang district, Nan province. This area will be replaced by concrete pathways and constructions. Consequently, if the high amount of rainfall affected the decreasing quality of water intake, the area will become the flooding area or the unavoidable runoff. Therefore, the objective of this research was to study the method to improve the efficiency of the runoffs per construction cost for the development in the specific area, Mueang Phu Phiang, Ban Muang Tuet, Moo 4, Phu Phiang District, Nan Province. The method of studying was integrated the knowledge between engineering and architecture which used as a model for designing dedicated to store, control and drain surface water or according to the model of Water Sensitive Urban Design (WSUD), Low Impact Development (LID) and the method of Best Management Practices (BMPs). The design of the physical state of soil and the selection of efficient absorb materials can increase the capability of taking runoffs per reasonable construction cost. Moreover, this is the method to prevent and reduce flooding areas to be a sustainable area where to prevent the runoffs.
