Abstract
The observed trends in moderate (25-50 mm per day) and heavy rainfall (50-75 mm, 75-100 mm and >
100 mm per day) events during southwest monsoon season and on annual basis in 26 districts of
Chhattisgarh state was worked out and Mann- Kendall test has been applied to understand the
significance the events. Results indicated that there is generally no significant trend of changes in the
events under moderate and heavy rainfall events in most of the districts during southwest monsoon
period as well on annual basis. However, significant increasing trend in 25-50 mm category has been
noted in Bemetara, Korba and Kondagaon districts. On annual basis, significant increasing trend is found
in Kawardha district while Balodabazar, Janjgir Champa, Koriya, Surajpur showed significant decreasing
tendency under 50-75 mm category. The trend in number of days with 75-100 mm rainfall showed
significant increasing trend in Bemetara and Mahasamund districts and significant declining trend is
observed in Janjgir Champa, Kondagaon and Surajpur districts. Significant increasing trend was observed
in Bemetara district under moderate and heavy rainfall events during southwest monsoon and on annual
basis and it is suggested that creating new drainage canals and community tanks / check dams may assist
the farming community to drain and to save the surplus rainwater during the heavy rainfall events.
