Abstract: In the past two decades major advances have been made which have enabled us tounderstand more clearly the physlcal processes which affect river regime[1,2,3,4].Previously the subject of river regime was treated purely empiricallyand relationships defining equilibrlum channel dimensions and slope were based onobservations of sand bed canals mainly in the Indian sub-continent [5,6].Morerecent studies of the equilibrium characteristics of alluvial channels haveenabled us to develop techniques,based on an understanding of the physicalphenomena,which predict the size and longitudinal slope of such channels interms of sediment size,sediment supply and water flow characteristics.This newanalytical approach,being based on sound physical principles,can be appliedover a wide range of conditions in terms of channel and sediment size.
