A framework of hydroclimate modeling and decision support tools for sustainalbe water resources planning in a changing climate

Abstract

Climate variability and change continue to threaten the sustainability of water resources around the world. Increasing temperature is likely to modify the timing, form, and intensity of precipitation events, which will alter regional and hydrologic cycles. Since drought, water shortages, and subsequent water conflicts may become an increasing threat in many international watersheds, sustainable water resources planning is critical to cope with climate change. In this study, the authors propose a framework of sustainable water resources planning based on coupled hydroclimate modeling and decision support tools to promote collaborative efforts against abrupt future climate change. A participatory modeling approach based on a stakeholder-driven decision support system will provide useful insights for water planners to pursue sustainable water resources under uncertain future climate. Additionally, the framework suggested by this study will facilitate multidisciplinary responses to future climate variability in the context of socioeconomic implications and policy decisions in human dimensions. © 2010 ASCE.
