|Flood hydrograph development
A procedure is advanced for constructing a flood-hydrograph prior to occurrence by analysis of three specific elements or factors that produce the hydrograph. 1) The outflow from surface runoff (snowmelt, rainfall), 2) the outflow from sub-surface storage, 3) the outflow from ground-water storage, and the introduction of a factor named loss characteristics for the particular basin under consideration. Portions of numerous hydrographs of past records are used to set up the cause and effects of the subdivisions of the hydrographs. Rainfall and snow melt enter the problem as snow storage. Graphs are exhibited and explained in the text together with the computed hydrograph and the actual hydrograph superimposed for comparison.
