Engineering Experts on River Tapi Dredging near Hazira Mangroves

River Tapi Dredging I’m looking for expert engineering perspectives on a proposed River Tapi Dredging R&D Project near the Hazira Mangroves (≈161 acres). The project aims to address river rejuvenation, sediment redistribution, flood prevention, and backflow mitigation. Based on our hydraulic assessment, Monsoon discharge ≈11300 cusec, width (465 & 680 m), slope 1/2130, bed roughness 0.04, the flow-depth-width relationship suggests dredging may be necessary to maintain stable velocity and prevent backflow. Yet despite submissions, the project remains stalled. From an engineering standpoint, what could be the major blockers, sediment transport modeling gaps, EIA issues, river morphology uncertainties, siltation cycles, dredged material management, or regulatory constraints? Any insights or references to similar case studies would be extremely valuable.
