The Europe floods this last week are unprecedented in so many respects. It has lead to close to 200 confirmed deaths so far, affected the Rhine basin areas of Germany, Belgium, Netherlands, Switzerland and Luxembourg. It is the result of worst recorded rainfall in a century, leading to unprecedented water levels that rose so suddenly that otherwise super alert and smart disaster management system could not neither accurately and in time predict the catastrophe nor remove these people from the path of the destruction. The climate scientists are seeing clear signature of climate change, though more studies are called for. The call for urgent and much more action to reverse the global warming are getting louder in a continent where possibly the climate action is most advanced.
As The New York Times reported on July 19, 2021 (Monday),
The authorities ordered new evacuations on Saturday, and heavy rains in the southern German region of Bavaria caused still more flooding on Sunday.
German meteorologists called the flooding the worst in 500 years, if not a millennium. The disaster thrust the issue of climate change to the center of pivotal elections this fall.
Belguim: Street pavements burst open, houses flattened, and entire villages were destroyed in what’s being described as one of the worst flooding disasters to hit Western Europe in more than two centuries. In Liège, Belgium’s third-largest city, water from the Meuse river overflowed Thursday evening into parts of the city center, prompting city officials to call for residents to evacuate the area or seek higher ground.
Countries like India should see this as a major and yet another wake up call to start taking action to reverse the global warming emissions. Much more can and should be done urgently.
1979 seems to be a watershed or may be bloodshed year about Dam Safety in India. That year, Central Dam Safety Organisation was for the first time set up in CWC (Central Water Commission). That was also a year in which over a 1000 delegates from all over the world gathered in Delhi under the aegis of ICOLD (International Commission on Large Dams). But the most important event or rather gruesome tragedy preceded both these developments. On Aug 11, 1979, the Machhu II dam disaster happened in Morbi in Saurashtra, Gujarat, that killed between 2000 (officially accepted by Central Water Commission) to 25000 people (local estimates).

On Aug 16, 2019, a news report[i] announced that Pune IMD (India Meteorological Department) will now (from Aug 1, 2019) provide to CWC (Central Water Commission) forecasts of water volume that may accumulate in river basins across the India “In a bid to ensure effective reservoir management.”
Pulak Guhathakurta, head, Climate Application and User Interface at Climate Research and Service at IMD-Pune was quoted saying, “We will make use of our forecasts and rainfall information to calculate the total volume of water expected to accumulate in every river basin and sub-river basin on the basis of its area expanse. This information will then be shared with CWC and other authorities, like the department of irrigation. It will be handy and can be decisive while deciding the release of water from time to time, especially during the monsoon.” This statement again emphasised that this was being done to help reservoir management. The news report than mentioned the Kerala floods in 2018 and role of dams therein. Continue reading “IMD forecast of Water Volume in River Basins: Can it help prevent Dam floods?”→
Blessings, like disasters, are complicated. Blessings come with a lot of attachments. And if you cannot manage them, you could invite disasters.
India is a blessed country in so many ways as far as water endowment is concerned. Our monsoons, rivers, aquifers, the Himalayas, the rich traditional techniques and management systems, to name a few. But the impacts of accumulated mismanagement over the last several decades are now coming out in the form of crisis in multiple ways. Continue reading “India’s Water Management Crisis”→
On Oct 29, 2018, another landslide dam blocked the path of Yarlung Tsangpo Dam, reportedly at the same location as the Oct 17,2018 landslide dam[i]. It breached on Oct 31, without any reported major calamity, but these repeated occurrences, twice in two weeks and third time in ten months (if we include Dec 2017[ii] landslides) raises a lot of questions. The silence of government of India institutions about the possible causes or other analysis, including by Central Water Commission, Union Ministry of Water Resources, National Disaster Management Authority or even National Remote Sensing Agency has, as expected, raised questions and speculations in Arunachal Pradesh. Continue reading “Another Landslide Dam on Yarlung Tsangpo raises more questions”→
ABSTRACT: Many independent observers have argued that dams have played a role in increasing the proportions of Kerala flood disaster during July-Aug 2018. This article shows that Kerala dams violated many basic norms and if operated prudently, could have helped. It shows how post dam floods are different than pre dam floods. It lists the steps that would help in future disasters involving dams. The lessons are useful for all large dams of India.
In theory, every dam can help moderate floods in the downstream areas, as long as and as much as the dam has space to store water. In fact, every action that helps to store, hold, recharge (to groundwater aquifer), delay flow of rainwater from the catchment to the river would help moderate flow and hence flood in the river. Our catchments are fast losing that capacity, with continued destruction of natural forests, wetlands, local water bodies and also soil’s capacity to hold water.

Central Water Commission is the only agency doing flood forecasting in India. As per CWC’s Flood Forecasting website[i] the Data Flow Map has information about 226 Flood Forecast Sites in the country comprising of 166 Level Forecast Sites and 60 Inflow Forecast Sites. It also monitors 700 other sites, information is made available through List Based Exploration and Hydrograph View, but no flood forecasting is done for these sites.

In order to better understand the CWC’s flood monitoring and forecasting work, in this article we have given an overview of CWC’s flood forecasting and monitoring sites in East India. It includes state wise list of CWC’s Level Forecast, Inflow Forecast and level monitoring sites in East India. Similar report has been published for North India[II] and North East India[III] and we hope to publish reports covering other regions of India too.
