- Abstract:
-
Rational method is widely used as one of the most popular hydrological calculation methods.A deducing method of the hyetograph and hydrograph was introduced with a case based on rational method, and a calculation method of stormwater detention basin volume in urban planning stage was proposed. The key of the method depended on the reasonable determination of runoff coefficient, concentration time and the discharge limit value of the planned runoff peak flow rate, and the reliability of the method could be verified based on the measured data. The method is conducive to further promotion and application of the rational method, and can provide a reference for the reasonable determination of stormwater detention basin volume in drainage and flood mitigation planning and sponge city planning.
