Researchers for this study will develop statistical methods to assess the impacts of climate change on surface water availability in Hawaii. The objectives of this study are to (1) develop statistical methods to estimate natural low flows at ungaged sites for current conditions and (2) evaluate the applicability of the developed statistical methods to estimate natural low flows for future conditions. Methods are illustrated in a case study to estimate changes in natural low flows of selected streams at gaged and ungaged basins on the island of Maui and associated impacts on habitat area for native aquatic fauna using available high-resolution projected climate information for the late 21st century.
