(some col.) Many cities are facing many water security issues that are increasing severely along with the pressure on the natural water resources . Therefore, putting the concept of water security into practice should be given more attention to achieve water resources managem ent. This research endeavored to devel op the water security framework at city scale and apply the framework for the Bangkok city . Water security definition of this study had combi ned integrated aspect that is: e very person at household level can access ea sy piped water supply with sufficient quantity to meet basic needs and be of acceptable safe quality, Water productivity of economic activities in the city should be measured, Water - bodies in the city must not be effected from pollution and contamination that are generated by the city, Acceptable level of water - related disaster to people in the city that consider urban flood damage and rainfall variation and Governance related to water should be more effective of water use and capacity of management. The water security framework has been developed as a composite index, involving twelve indicators, ten variables and five dimensions. The five dimensions of this framework are domestic, economic, environmental, water - related disaster and governance and managem ent. For developing water security framework, DPSIR framework and SMART criteria were used for identifying and selecting the composite of indicators. The estimat ion of the overall water security index was done applying an equal weight for indicators, varia bles and dimensions . The developed fram e work was applied in the Bangkok city. Based on the data availability, these case study area was divided into two spatial (Eastern and Western). Also, this study selected five districts (Sathon, Lat Phrao, Nong Chok, Bangkok noi and Nong Kheam) in Bangkok to quantify the WSI at different spatial scales . Temporal scale of this study was a period eight years between 2007 and 2014. Finally, the result of application of the framework shows the overall WSI in Bangkok has ac hieved moderate level over 8 years. For district scales, the overall WSI in selected districts has also achieved moderate level over 8 years but a little higher than the overall WSI in Bangkok.
