CEGIS Services

River Management

CEGIS is the unique institution, which has developed extensive knowledge base on the river morphology in Bangladesh and provides solutions to issues related the river management. The rivers are alluvial, frequently shifting their courses and are required to carry flows and sediments and, unlike other rivers of the world, to build lands. Stabilizing the river courses as well as for any intervention in the flood plains requires deep understanding of the geo- and river morphological dimensions. For this purpose, the morphological analysis of time-series data and data collected from physical survey are routinely analyzed and the changes in the river courses are monitored and forecasted. Over the years, CEGIS has generated considerable knowledge and experiences to understand the river morphology as well as its role in delta building process. The following models are developed and being perfected:

• Erosion Prediction Tool
• River Morphology Model
• Delta Development Model
• Conceptual Model on Evolution of Rivers in the Haor Areas
