Data on daily precipitation over about 80 years at 24 places in the Netherlands were available in two forms: in chronological order and per month as frequency distributions of precipitation amounts of one and more days.The negative binomial distribution was fitted to these frequency distributions and the trend of the parameters was related to the number of days and to the correlation coefficient of the successive amounts of precipitation. The usefulness of truncate negative binomial distribution was examined.The distribution of maximum precipitation in a period of 1, 2 and 3 days within a month accorded well with the double exponential distribution; the parameters within each month were related to distance from the coast.In an agrohydrological model with variable intensity of discharge and variable maximum moisture deficit, the differences were studied in some agrohydrological criteria calculated with the observed series of precipitation data or with the frequency distribution only.
