  Integrated Hydrological and Hydraulic Models for Investigation of Channel Morphological Change and River Bank Erosion: A Case of Mersa River, Ethiopia
  Author(s): Yonatan Tibebu*, Hussen Ali, Fikru Fentan and Yohannes Wodaje
  
  The land use/cover change and other natural and human factors in catchments result in changes in discharge and sediment supply. As a result, the river morphology becomes altered. Morphological change of natural rivers in terms of vertical adjustment and horizontal planform is an important indicator of true channel stability and has a significant effect on lateral bank retreats. The overall goal of this research is to look up the morphological change in rivers and the effect that occurred within the Mersa river. Two commonly used models: the HEC-RAS and SWAT models were used in combination. The first, model SWAT was used to analyze the hydrologic responses of the watershed. Subsequently, the SWAT model's outputs (streamflow and sediment) were then used as input into the hydraulic model HEC-RAS, for simulation of the hydraulics of the river along 2.1 km of the Mersa river to investi..
