Preliminary findings• Tidal Basins are crucial for the Hari river• Only siltation is possible, no redirection• Increased siltation due to reclamation on new floodplains• What is Tidal River Management? – Water management? – Sediment management? – Flow velocity management? – Tidal volume management?
Leendert – research objectives• To map current water management practices in Hari-Mukteswari river.• To find how different stakeholders perceive “TRM”• To find current problems regarding water management in Hari-Mukteswari river.
99% of people want TRM& regard it essential to their livelihood
Communities and Institutions for Flood Resilience Turning Tides?
What happened?• BWDB & MPs at Kapalia to open tidal basin• Demonstrators prevented the opening• 12 cars burned• BWDB and govt. officials fled for their lives
Why?• Peripheral embankments construction• Compensation: – Bureaucratic procedure – Land inheritance – Enemy land• Beel Khuksia experience: – Initial plan: 3-4 years – Now: 6 years• Low trust in government
Common conclusions• Tidal basins are crucial for the Hari river• “Scaling” is essential in understanding “TRM”: – Focus on entire river and delta, not tidal basin• Challenges pertaining to TRM are political rather than physical
