Abstract

Rainfall characteristics of the Chambal catchement were studied. Wide and irregular variations in the total number of ralay days were observed over the catchment. Frequency of maximum twenty four hours rainfall was also worked out. It varies from 85 mm to 323 mm in the catchment.

Abstract

Analytical presentation of 75 years of rainfall data of Kota has been attempted in this paper. Variability of annual rainfall, its trend, annual and monthly distribution together with the maximum intensity of different storms ranging from 5 minutes to 60 minutes duration have been presented. The analysis indicates a slight increasing trend in the annual precipitation. While there is a wide variability in rainfall from year to year and from month to month, the study reveals a better consistency in the distribution of rainfall during Kharif season, while during Rabi season the variability in distribution is much more. There appears to be no hope for increasing production without adequate measures for conserving water and without providing irrigation facilities in the region.

Abstract

Rainfall frequency data over a period of 12 years from 1956 to 1967 of an automatic recording raingauge at the Soil Conservation Research, Demonstration and Training Centre, Kota, have been analysed and discussed in this paper. The curve indicating the rainfall-intensities and durations have been drawn after analysing the data which yield a family of parallel curves. The general equation representing the curves for the region is given by: I = K/(t+a)^d; where, I = Rainfall intensity in inches/hr. t = Duration in minutes; and, K, a and d are constants. The values of K, a and d have been worked out for different frequency periods.
