Abstract: In practice, runoff peak flow rates are typically estimated by the rational method, a design storm unit hydrograph (UH) method, or a statistical regression equation. In this technical note, the balanced design storm UH ...

Abstract: Given a set of realizations of error data (i.e., the difference between model runoff estimates and stream gauge data) from rainfall-runoff hydrologic models, it is possible to generate a set of error transfer function ...

Abstract: There is no agreement on the best way to develop flood frequency curves and synthesize runoff peak flow rate data, and no precise procedure which applies to all cases of flood frequency statistics. Consequently it is prudent ...

Abstract: A method of approximating the solution of the Laplace equation in two‐dimensions is presented. The numerical approach is to determine a complex variable polynomial which satisfies the specified boundary conditions along a ...

Abstract: The rational-method equation for estimating peak flow rates for storm-water runoff is derived from the balanced-design storm unit hydrograph approach presented in the U.S. Army Corps of Engineers HEC Training Document 15. ...

Abstract: The diffusion equation is a simplification of the two‐dimensional continuity and momentum equations. This simpler dynamic model of two‐dimensional hydraulics affords the hydrologist a means to quickly estimate floodflow ...

Abstract: A mathematical model is developed to describe changes in ice volume in the cryosphere. Modeling the cryosphere may be useful in assessing future climate impacts currently captured by global circulation models (GCMs) by ...

Abstract: This paper focuses on the development of simplified mathematical models of the cryosphere which may be useful in further understanding possible global climate change impacts and in further assessing future impacts captured ...
