Description
For many design purposes, it is necessary to determine the maximum depths of precipitation(P) within a given sorm for various areas(A) and durations(tT).
Over the Hi River basin(914 sb. km), in this paper, the maximum depths of precipi tation were analyzed by using storm records from 11 stations as shown in Fig. 1.
The relations between P and A were well described by following formulas ;
P/(P_0) = e^<-αA^β>, P/(P_0) = a/((A+b)). P/(P_0) = a/A^n, and P/(P_0) = a/((√<A+b>)).And the most accurate method for computing P was the use of P/(P_0) = e^<-αA^β>. However, the parame ters of α, β, a, b, and n in fomulas varied with storms and their durations.
P = a/((T^b+A^c+d)) was proposed as the formula containing a term, T, but the accuracy was not satisfactory.
