Water is one of the necessities for supporting the life and improvement of society. Water is an extremely valuable endowment of nature to humankind. The significant wellspring of water is precipitation and for a large portion of the hydrological models, precipitation is utilized as one of the principal components to gauge the spillover interaction. The precipitation overflow model is a numerical model portraying the precipitation spillover relations of a waterway bowl or watershed. Precipitation information is questionable and overflow is one of the significant hydrologic factors utilized in water assets the executives and arranging. Rainstorms create overflow and its event and amount are subject to the attributes of the precipitation occasion. In any case, there are numerous watersheds or catchments that are unchecked; Thus, exact formulae were valuable for assessing overflow volume. This paper depicts the assessment of overflow utilizing observational conditions like Khuzla’s equation, English and Desouza recipe, Indian Irrigation Department, and Khosla’s recipe. For this reason, the Hoshangabad area is chosen and the yearly precipitation information from 1981 to 2017 has been gathered. Furthermore, the appropriateness of the model has been assessed by contrasting the overflow information and one another. After comparing the result of annual runoff calculated by using those formulas, we can observe that in all the years values of the Khosla formula and Khuzla formula are showing similar results, but in the English and Duez formula the value of runoff is too high. The runoff values calculated from the English and Duez formulas are nearly 7 times the actual value obtained from the other three formulas. So, it is not acceptable for the Hoshangabad region.
