A sustainability study of the flow regulation impacts by dams in a carp breeding river using the hydrodynamic model and building block analysis
Published in SN Applied Sciences, 2019
The study addresses the threats to the Halda River, Bangladesh’s only natural carp spawning ground, due to human interventions and natural causes. These threats include pollution, infrastructural changes, and climate impacts. The study aims to assess the ecosystem, sustainable management, and flow regulation impacts of dams on the river. Using a hydrologic model (ArcSWAT) and a hydrodynamic model (Delft3D), the research simulates scenarios with and without dams to understand their effects on fish breeding conditions. The Tennant method is employed for environmental flow analysis, assessing impacts on fish habitats and spawning. The findings are further analyzed for velocity profiles to ensure sustainable aquatic habitats in the Halda River.
