| Zusammenfassung |
| Streamflow information is critical for addressing any number of hydrologic
problems. Often, streamflow information is needed at locations that are
ungauged and, therefore, have no observations on which to base water
management decisions. Furthermore, there has been increasing need for daily
streamflow time series to manage rivers for both human and ecological
functions. To facilitate negotiation between human and ecological demands
for water, this paper presents the first publicly available, map-based,
regional software tool to estimate historical, unregulated, daily streamflow
time series (streamflow not affected by human alteration such as dams or
water withdrawals) at any user-selected ungauged river location. The map
interface allows users to locate and click on a river location, which then
links to a spreadsheet-based program that computes estimates of daily
streamflow for the river location selected. For a demonstration region in
the northeast United States, daily streamflow was, in general, shown to be
reliably estimated by the software tool. Estimating the highest and lowest
streamflows that occurred in the demonstration region over the period from
1960 through 2004 also was accomplished but with more difficulty and
limitations. The software tool provides a general framework that can be
applied to other regions for which daily streamflow estimates are needed. |
