N2 - Rapid urbanization and population growth have increased around the world’s natural water resources more than ever. The changes in land use due to increased urbanization cause impervious surfaces leading to extreme to severe urban flooding and deterioration in water quality. The aforementioned issues can be minimized by employing Nature Based Solutions (NBS). In recent decades, NBS have been adapted for urban drainage in developed countries, mostly having temperate climate while there is a need to develop similar sustainable measures for urban drainage in tropical regions as currently there are no guidelines for their implementation in tropical climate. In this study multi criteria decision analysis (MCDA) approach was utilized to identify the best site for NBS in Asian Institute of Technology (AIT), Thailand. The NBS type used in this study was Bioretention system and the number of alternatives is three. To select one alternative among three Analytical Hierarchy Process (AHP) method was adapted. Ten criteria were determined as suitable, based on different dimensions of sustainability including economic (Design and capital costs), environmental (Stormwater quality indicators), technical (Soil parameters, catchment size, contributing structures and physical restrictions) and Social (Aesthetics). The results strongly suggested that Site-2 is a suitable alternative having maximum value of overall priority calculated by AHP process. The present study will provide a guideline for deciding the most suitable site for the operation of bioretention system for urban water management in tropical climate. Moreover, the results obtained in this research will be used for further design and execution of NBS project in AIT.
