Webb14 apr. 2024 · Glacierized coastal catchments of the Gulf of Alaska are undergoing rapid hydrologic fluctuations in response to climate change. These catchments deliver dissolved and suspended inorganic and organic matter to nearshore marine environments, however, these glacierized coastal catchments are relatively understudied and little is known … WebbThe Rational Method remains one of the most widely used approaches for estimating peak discharge in small catchments. In one widely used interpretation of the Rational Method, the maximum possible peak discharge produced by a storm with a given return period is predicted by setting the storm duration equal to the time of concentration.

In southern Europe flood trends are generally negative.
Webb1 jan. 1998 · A major advantage in studying small catchments is that spatial extrapolations from point measurements can be made with a greater degree of confidence than for large catchments. However, that does not necessarily mean that these extrapolations are … WebbFigure 6 clearly shows that the catchments with relatively small β values (0.01–0.5) have flat slopes, and these catchments are mostly located in Great Plain the interior region of the CONUS. This means the flatter catchments tend to generate relatively dampened flood peaks, as indicated by smaller β values.
