Abstract
Based on daily streamflow and suspended sediment load data from five gauging stations located on Wainganga basin, spatial and temporal variations in seasonal streamflow and suspended sediment load from 1969 to 2018 are investigated. The Mann–Kendall (MK) test, Spearman’s rank correlation and Innovative trend technique (ITA) are applied to detect the trend in seasonal streamflow and suspended sediment load. The Sen’s slope test is used to find the trend magnitude. MK test indicates increasing trend in streamflow at Kumhari and Rajegaon stations, whereas Spearman’s rank correlation test and Innovative trend techniques report decreasing trend for both the stations. Similarly, MK test reported increasing trend in suspended sediment load at Rajegaon and Satrapur stations. But, Spearman’s rank correlation test and Innovative trend techniques report decreasing trend for both the stations. Compared to MK trend test, ITA technique showed good agreement with Spearman’s rank correlation.
