Kerala: Dams Floods 2018: Follow Rule Curves to Avoid Flood Disasters

Unprecedented Kerala deluge[1] that swept through the coastal state on the day of Independence day 2018 was most disastrous flood incident in the year. It has also been termed as one the worst flood in the state and reminded the people of July 1924 and July 1962 flood calamities. Many experts, several reports and studies have established the role of dams in worsening the deluge. According to reports, 35 out of the 46 dams within the state were opened for the first time in history[2]. All 5 overflow gates of the Idukki Dam were opened at the same time, for the first time in 26 years.

State Government Accepts Dams Role

Kerala is usually considered a flood-proofed[3] state with its undulating terrain. For a state that receives an annual average rainfall of nearly 3,000 mm, its natural landscape protects it from recurrent floods. Indeed, the Kerala flood has highlighted our poor dam management[4] system. 

As per officials the crisis could have been contained[5] had the state “gradually released” water from at least 30 dams, in advance of high rainfall, adding that local authorities failed to foresee the imminent danger with high rain predictions. “Such floods have probably recurred after 100 years, exposing the State’s unprofessionally run reservoirs management system and unpreparedness on disaster mitigation and disaster resilience.

DRP News Bulletin 3 Sept 2018: CHINA HAS STARTED DECOMMISSIONING DAMS

In a mountain village in southwest China’s Sichuan province, authorities have demolished seven small dam projects this year along a river to clear illegal developments in a new nature reserve. The demolition is part of a nationwide programme to close hundreds of tiny and often ramshackle dams and turbines and bring order to China’s massive hydropower sector after years of unconstrained construction.

The dams sat on an unnamed tributary of the fierce and flood-prone Dadu river, which feeds into the Yangtze, Asia’s largest and longest river, where the government says the “irregular development” of thousands of small hydropower projects has wrecked the ecology. But green groups say the campaign will not necessarily save the environment because it will not affect big state hydropower stations, which they say have caused the most damage.

On the 48 km Zhougong, authorities have already demolished small projects built in nature reserves or encroaching upon new “ecological red lines” drawn up to shield a quarter of China’s territory from development.

The government says small dams have disrupted the habitats and breeding patterns of many rare species of fish, although green groups argue the damage wrought by bigger dams is more severe, with entire towns and ecosystems submerged in water, which they say increases the risk of earthquakes, landslides and even climate change.

DRP News Bulletin 9 July 2018: National Meeting on Inland Fishworkers in Delhi on July 10, 2018

The NATIONAL PLATFORM FOR SMALL SCALE FISH WORKERS (INLAND) is convening a Consultative Meeting on Livelihood Issues of Inland Small Scale Fish Workers 10thJuly 2018, Gandhi Peace Foundation, New Delhi.

The Invitation letter says: “India is gifted with vast and varied inland water bodies bearing rich fish resources.Rivers and canals, reservoirs, ponds and tanks, oxbow lakes, wetlands, backwaters and estuaries yield 7.21 million tonnes of fish which is more than 66% of total fish production of the country. The sector sustains about 4 million fish workers and a total population of around 2 crores.Fish provides good quality animal protein rich in minerals and vitamins. About 800 million Indians eat fish. After milk, fish is the largest source of our animal protein.These huge resources are under severe stress. Rivers are poisoned with heavy pollution. Diversion of water from rivers is harming their ecological flow.

NASA’s GRACE Mission: India on perilous Path of making millions of climate refugees

Massive human induced freshwater redistribution with profound consequences A 14-year (April 2002 – March 2016) NASA’s GRACE (Gravity Recovery and Climate Experiment) mission[i] has confirmed that a massive redistribution of freshwater is occurring across Earth, with middle-latitude belts drying and the tropics and higher latitudes gaining water supplies. The results, which are probably a combination of the effects of climate change, vast human withdrawals of groundwater, Dams and natural changes, could have profound consequences if they continue.  Continue reading “NASA’s GRACE Mission: India on perilous Path of making millions of climate refugees”

DRP News Bulletin 11 September 2017 (Why This Rally Won’t Help The Rivers?)

The news media is filled with this new kid on the block, trying to wake the nation about the need to save our rivers… amazing to see so many film stars, politicians, governments, and public personalities, many of them rather innocently joining the band wagon… some friends were pleading that see, he is able to take the message of rivers to so many people, including lakhs of children… let us try and see if there is something positive here… may be, may be this is just the entry point, but the guy and his team have bigger vision? May be we need to give him longer rope, be more charitable and not jump to negativity?

We have kept all this in mind while writing this.

We see nothing from the people who are leading the rally, or their websites or messages that they understand the real threats faced by and reasons for the state of our rivers, are ready to even list such causes or protest any further move to destroy our rivers. The website claims it is “a nationwide awareness campaign to revive our rivers”. Can missed call save our rivers?
