Importance of record length with respect to estimating the 1-percent chance flood
Toby D. Feaster
2010, Conference Paper, 2010 South Carolina Water Resources Conference
U.S. Geological Survey (USGS) streamflow gages have been established in every State in the Nation, Puerto Rico, and the Trust Territory of the Pacific Islands. From these st reamflow records, estimates of the magnitude and frequency of floods are often developed and used to design transportation and water- conveyance structures...
Map correlation method: Selection of a reference streamgage to estimate daily streamflow at ungaged catchments
Stacey A. Archfield, Richard M. Vogel
2010, Water Resources Research (46)
Daily streamflow time series are critical to a very broad range of hydrologic problems. Whereas daily streamflow time series are readily obtained from gaged catchments, streamflow information is commonly needed at catchments for which no measured streamflow information exists. At ungaged catchments, methods to estimate daily streamflow time series typically...

Sandra K. Poppenga, Bruce Worstell, Jason M. Stoker, Susan Greenlee
2010, Conference Paper, Remote sensing and hydrology
The methods to extract surface flow from coarse elevation data are well documented; however, the methods to extract surface flow from high-resolution, high-vertical accuracy digital elevation models (DEMs) derived from light detection and ranging (lidar) are less documented, but yet more complex. As lidar data are increasingly used to generate...
