‘Unprecedented’ events and ‘unexpected’ impacts are commonly to blame after major floods and other disasters. While the realities of both disaster risk and climate change are that they are uncertain, many disasters have historical precursors and foreseeable impacts if careful attention is paid to the dimensions of risk including physical hazards and the exposure and […]
Pumpkin farming in Bangladesh helps some of the most vulnerable people to cope with floods & climate change and so escape poverty. This reveals critical lessons for some of the biggest problems our world faces.
The island of Rajapur is a place literally made by floods, created as the Karnali River drops sediment from the Himalayan foothills just a few kilometers north of the Nepal-India border. As the river loses momentum, it splits to form a large inland delta riddled with wandering channels and sandbars. Changeable landscapes like this are […]
In this blog post, Dr. Dilip Gautam (Senior DRR Consultant – PAC) considers sediment and flooding dynamics within the Karnali basin. In most of the current flood risk management practices, the role of sediment dynamics is not dealt with sufficiently. Sedimentation of river channel and floodplain has serious impacts on aggravating flood risks in alluvial […]
This blog post by explores the basin-scale water resource management of the Karnali River and critically examines how often the water resource development projects are undertaken in a coordinated way considering the ecological benefits of the river. He highlights the need of comprehensive river basin plans and thorough understanding of complex river dynamics for sustainable […]
This blog entry focuses on the challenges in the choice of model input parameters, terrain data and modelling software in flood modelling of rivers, especially those in Nepal. Her post tries to acknowledge the limitations of flood inundation maps generated through these models.

Flood-resilient toilets being tested in North-Western Bihar could make sanitation safe and secure for the many millions regularly affected by floods.
After a disaster, people talk about build back better. The flood disaster in the second week of August in Nepal told us to do better preparedness and ‘bring back better’.
