The spreadsheets associated with this metadata file represent: (Tab 1) Streamflow and drainage basin characteristics of selected gaged steams in Hawaii used to develop statistical models to estimate surface-water availability during low flow conditions and for varying rainfall conditions. For gaged streams on Maui, two sets of projected rainfall conditions for the late 21st century and associated estimates of changes in low flows and usable habitat for native stream fauna are also provided. (Tab 2) Drainage basin characteristics of ungaged streams on Maui used to apply the statistical models, two sets of projected rainfall conditions for the late 21st century, and associated estimates of changes in low flows and usable stream habitat. A list of the stream characteristics and study results are included in this metadata file as well as references for data sources. Refer to Bassiouni et al. (in press) for details of the methods and data sources used to determine these characteristics and results. Streams were classified based on the elasticity of low flows to rainfall and multiple linear regressions were developed using random effects panel regression methods as described in Bassiouni et al. (in press).
