QUATERNARY FLUVIAL SYSTEMS IN UPLAND MAHARASHTRA

Detailed geomorphic, stratigraphic and chronologic data reveal that ma jor aggradational episodes in the Upland Maharashtra were associated w ith flow-regime changes. Four major alluvial formations and one colluv ial formation reflect the spectrum of fluvial activity at different di scharge stages of the Upland rivers during the Quaternary period. The alluvial sequences exhibit signatures of changing fluvial regime from meandering to non-meandering channels or from bed-load to suspended-lo ad channels. The fluviatile evidence points to a synchronous pattern o f depositional events associated with the Quaternary climatic changes for these geomorphologically stable channels, during the last 1.4 m.y.
