Flood mitigation is a related but separate concept describing a broader set of strategies taken to reduce flood risk and potential impact while improving resilience against flood events. As climate change has led to increased flood risk an intensity, flood management is an important part of climate change adaptation and climate resilience .
With the rainfall, flash floods almost always affect the floodplains in some way. However, in recent years, the damage from the floods has become much more severe, with 2006, 2011, 2012, and 2013 causing tremendous more damage than previously. [1] In 2006, the flooding was the most damaging flood in East Africa in 50 years. [6]
Disaster risk reduction (DRR) is defined by United Nations Office for Disaster Risk Reduction (UNDRR) as those actions which aim to "prevent new and reducing existing disaster risk and managing residual risk, all of which contribute to strengthening resilience and therefore to the achievement of sustainable development".
Scholars have studied the floods in Mumbai from the perspectives of climate change, disaster management / mitigation, urban health, vulnerability and adaptation, hydrology, environmental degradation and encroachment etc. Kapil Gupta (2007) assesses urban flood resilience, while Andharia (2006) contrasts the "widespread acts of generosity and ...
The flood reached the Teesta III Dam at Chungthang at midnight, before its gates could be opened, destroying the dam in minutes. [2] Water levels downstream in the River Teesta rose by up to 20 feet (6.1 m), causing widespread damage. [3] It was the deadliest flood in the area after the 1968 Sikkim floods when around 1000 people were killed. [4]
Structural measures consist of 81 dams, reservoirs and flood embankments. Non-structural measures include flood hazard mapping and landslide zoning, but larger scale maps are needed to develop effective mitigation plans. [64] [66] River discharge is monitored at 38 river gauging stations by the Central Water Commission. [67]
