Hydrulic Scientists believed that Major 3 factors are causes to braided river as follows . 1) Plenty fluctuation river dischange 2) Greatly bed load 3) Relative steep slope until don't meandening Accourding to these 3 factors in phase 1 project below cases by river behavier was study 1) Relation width to slope river. 2) Relation width to kind's of bank river & it's rate standing erosion against to flow . 3) The examination of relation flood fluctuation & river channel changes . 4) The examination of relation granulate sieve curves to channel changes that to be effected flood rating . That was result of above studies as follows . 1) To accompanying with increase width are decresing change fluctuations river slope . 2) Resistance changes bank river is causing that river either forming sinousity in length of channel has convergence & divergence that are convergences as control points in state flood acts for river downstream . 3) Flood hydrograph from determin flow direction in convergences upstream . 4) Granulate curve show that both banks sediment river in place sedmention deposit is difference from convergence , that result from river sedimention in different dischange . In supllementary projects also would study effect of land slides, intensity erosion of banks and influence of structures and pervious projects in this river .
