WebHydrological Theory. The synthetic hyetograph computed by the Chicago method is based on the parameters of an assumed Intensity-Duration-Frequency relationship, i.e. a,b,c = constants dependent on the units employed and the return frequency of the storm. The asymmetry of the hyetograph is described by a parameter r (where 0 < r < 1) which ... WebOct 12, 2005 · UHG provides the capability to generate, compare, and edit a variety of synthetic unit hydrographs for basins within the RFC area of responsibility.

WebChicago Storm Data. This method (Keifer and Chu, 1957) allows for determining a synthetic hyetograph starting from the empirical relationship of the IDF curves. Let us consider the general form of Talbot IDF formula: According to Debordes (1974) the coefficient r is evenly distributed across the interval (0, 1) so that the most probable value ... WebThe unit hydrograph represents the lumped response of the catchment to a unit rainfall excess of D-h duration to produce a direct runoff hydrograph. It relates only the direct runoff to rainfall excess. Hence the volume of water contained in the unit hydrograph must be equal to the rainfall excess. Since a rainfall excess of 1cm is considered ... hawks vs thunder history
