Hydroclimatology of the continental United States
[1] The overall water balance and the sensitivity of watershed runoff to changes in climate are investigated using national databases of climate and streamflow for 1,337 watersheds in the U.S. We document that 1% changes in precipitation result in 1.5–2.5% changes in watershed runoff, depending upon the degree of buffering by storage processes and other factors. Unlike previous research, our ap...
متن کاملAnnual hydroclimatology of the United States
[1] An overview of the annual hydroclimatology of the United States is provided. Time series of monthly streamflow, temperature, and precipitation are developed for 1337 watersheds in the United States. This unique data set is then used to evaluate several approaches for estimating the long-term water balance and the interannual variability of streamflow. Traditional relationships which predict...
متن کاملMultidecadal streamflow regimes in the interior western United States: Implications for the vulnerability of water resources
[1] In the interior western United States, increased demand for water coupled with the uncertain nature of anthropogenic and natural hydroclimatic variations add challenges to the task of assessing the adequacy of the existing regional water resources systems. Current availability of relatively short instrumental streamflow records further limits the diagnosis of multidecadal and longer time va...

15 صفحه اولSpatial scaling properties of annual streamflow in the United States
The spatial scaling properties of annual average streamflow is examined using records from 1 433 river basins across the continental United States. The log-linear relationship ln(E[Q']) = a + brln(A) is representative throughout the United States, where E[Q:] represents the expectation of the rth moment of annual streamflow at site i, and Â, represents drainage area. The scaling model parameter...
