In this paper, I present the ratio of "C" which is the ratio of intensity between daily rainfall and arbitrary duration rainfall in six districts; Taejon, Gongju, Nonsan, Hongsan, Geumsan and Hongseong in Chung-nam district, and determine probable daily rainfall by the method of statistical treatment by theory of probability, and then climinate previous improper maximum daily rainfall in river plan "C" formula in chung-nam district is c=b/(a+t) in which, t=duration of rainfall, a and b=constant. These types of formula and constant are determined by choosing the value of the maximum daily rainfall of every year as a data in the meteorological stations of six districts mentioned above, and applying the Mononobe's formula to it. According to the records of fundamental materials for twenty-five years, if the values of calculating the probab'c daily rainfalls are indicated in percentages to the values of previous maximum daily rainfall, they are as follows:the value of ten years is 75%;twenty years 87%;fifty years 100%; one hundred years 110%; two hundred years 120-130%. For the most part, if the previous improper maximum daily rainfall is taken as the probable daily rainfall, it is applicable to the value of 30~60 years and the second rank is applicable to the value of 10~30 years.
