Overview of CWC’s Flood Forecasting Sites 2019: North East India

Central Water Commission (CWC) monitors water level at several hundred sites in the country during monsoon every year. It publishes this information on its Flood Forecast (FF) website[I]. The website has three ways to get this information: Data Flow Map, List Based Exploration, and Hydrograph view. The Hydrograph view provides information for past 72 hours, supposed to be updated every hour. This is in addition to the list of current forecasts.

The CWC’s FF website had in 2018 monsoon, information about 226 Flood Forecast Sites in the country comprising of 166 Level Forecast Sites and 60 Inflow Forecast Sites. It also monitors 700 Flood sites, information made available through List Based Exploration and Hydrograph View. As reported below, the number of sites have gone up during 2019 monsoon, which is welcome. However, most of the new sites, along with some old ones do not have key information.

North East India Sand Mining 2018: Emerging threat to Rivers

Thoubal River 

Manipur DFO bans mining in Thoubal river Showing serious concerns to the degradation of the Thoubal River as well as its environment, a team of state police and Forest department officials led by District Forest Officer (DFO) RK Amarjit paid surprise visit at Moirang Purel and Itham area under Andro Assembly constituency where sand mining was underway at mass scale. During the inspection visit the govt official saw illegal excavation of soil from nearby hills of the area and dump it at Thoubal River for extraction of red sand.

As the mining of sand not only endangered the forest area of the surroundings but also degrades the condition of the Thoubal River, the DFO put immediate ban on the sand mining as well as excavation at hills of the surroundings. He also ordered ban on transportation of red sand in Thoubal and Kakching district. http://kanglaonline.com/2017/11/dfo-thoubal-swings-into-action-bans-sand-mining-at-thoubal-river/ (21 Nov. 2017)

HFL crossing flood events during India SW Monsoon 2018

Even as the rainfall during South West Monsoon of India during June Sept 2018 was 9.4% below normal, a number of HFL (Highest Flood Level) crossing flood events were recorded on CWC’s (Central Water  Commission) Flood Forecasting (FF) website[i]. Since CWC’s FF site does not provide archived information or comprehensive list of such events, we are here putting together a list of such events that we had noted during the SW monsoon, for future records and also understanding trends of high floods.

Overview of CWC Flood Monitoring Sites 2018: INDIA

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 Flood sites, information 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, SANDRP has published report of CWC’s Level Forecast, Inflow Forecast and level monitoring sites in 5 zones of North India[ii], North East India[iii], East India[iv], South India[v] and West India[vi].  Through this report, we have presented all the data at one place with links to separate zone wise reports with detailed description.

Monsoon

The mirage of normal monsoon

According to IMD, India is having normal monsoon this year, so far, as per rainfall till date (Sept 1, 2018). Against normal rainfall of 721.1 mm, India has received 676.6 mm rainfall, which is 6.2% below normal, considered within normal rainfall definition as per IMD. So India is having normal monsoon rainfall, says IMD. Let us check this against some ground realities.

However, East and North East India, one of the four regions for which IMD provides rainfall data, has so far had 27% below normal rainfall, while South India had 9% surplus rainfall.  Thus, while at all India level, what seems all normal, is average of different, though serious departures from normal rainfall. Let us say this is first level of mirage of normal rainfall. Continue reading “The mirage of normal monsoon”

In order to better understanding the CWC’s flood monitoring and forecasting work, in this article we have given state wise list of CWC’s Level Forecast, Inflow Forecast and level monitoring sites in North East India. For better understanding, we have also included part of West Bengal that is in Brahmaputra basin here, in addition to the 8 North Eastern states. Similar report has been published for North India[II] and we hope to publish reports covering other regions of India too.

Floods in Tripura, Mizoram, Barak Valley in June 2018

The second wave of floods (first wave came in around May 20-24) this year inA North East India is affecting Tripura, Mizoram and mainly Barak Valley in Assam. Worryingly, while CWC flood forecast site shows water level reaching unprecedented levels in Manu river at Kailashahar in North Tripura District, CWC seems to have NO flood forecasting site in Mizoram. At Matizuri site in Hailakandi district in Barak Valley in Assam, the Katakhal river also approaching its highest ever flood level. In Bangladesh too sites like Amalshid have crossed the HFL.  Continue reading “Floods in Tripura, Mizoram, Barak Valley in June 2018”

Analysis MoWR’s Advisory Committee’s Decisions for Northeast – January 2009 to Dec 2013

This is analysis of the decisions of the Advisory Committee in the Union Ministry of Water Resources for consideration of techno-economic viability of Irrigation, Flood Control and Multi Purpose Project Proposals (TAC in short) for North East India[1] from 95th meeting of January 2009 to 122nd meeting held in December 2013. In our last analysis of TAC minutes we have covered the decision taken for NE states from July 2011 to December 2013 which  is available at – https://sandrp.wordpress.com/2014/03/19/lack-of-transparency-and-accountability-remains-the-norm-of-functioning-for-mowrs-advisory-committee/. In this analysis, we have covered the same for an extended period. In these five years TAC has accepted project proposals worth of 5515.46 crores. In calculating the total cost of the projects considered we have considered only the projects whose proposals were given clearance by TAC. In these five years, some of the projects also made two appearances with revised costs. In such cases the higher revised cost has been taken into consideration, e.g. Khuga Multipurpose Project and Dolaithabi Barrage Project, both located in Manipur were accepted by the committee in its 100th meeting (held on 9th October 2009) with revised cost of Rs 381.28 crore and 251.52 crore respectively. In the 115th meeting (held on 24th July 2012) of the TAC, these two projects were considered again where the cost for Khuga Project was Rs. 433.91 cr and for Dolaithabi Project it was Rs. 360.05 Cr. The same is the case for the Thoubal Multipurpose Project which appeared in 101st and 115th meeting of the TAC.

Within these five years, TAC has given financial clearance to 26 flood and erosion control projects and majority of these projects are from Assam. The committee gave the clearance to 6 irrigation projects, 3 barrage projects and 3 multipurpose projects.[2] The committee also gave clearance to a strom water drainage improvement project below Greenfield Airport at Pakyong in Sikkim within this period.

In this period, largest no of considered (25) and approved (20) projects were from Assam. Assam also has the maximum cost of projects among all states (Rs. 2631.99 Cr). Highest number of projects were considered (16) and approved (14) in the year 2009, with total cost of Rs 2321 Crores, which too was highest among all the years.

As found in our previous analysis, in the last five year from 2009 to 2013 TAC has not rejected a single project. Five projects had been deferred but were approved in the subsequent meetings within the same period. In the 108th meeting (held on 4th January 2011), the TAC did not discuss two projects on the Brahmaputra river stating “It was observed that the flood control and anti erosion scheme of Brahmaputra Board are implemented through Central Fund, which do not require investment clearance from the Planning Commission. Therefore, these schemes need not be put up to the Advisory Committee. However, the technical aspect of such project may be looked into by Central Water Commission as per past practice.”  But both these projects were reconsidered in the 110th meeting of TAC (held on 20th July 2011) and were cleared by the committee.

So this seems like a rubber stamping committee, clearing everything that comes to it. Reading of the minutes of the meetings also reveals that there are hardly any critical questions asked on merits of the questions for the massive delay and cost escalations that most of the projects suffer. Nor is there an discussion about the performance of the projects.

As we noted earlier, this committee functions in most non transparent, non participatory and unaccountable way. Neither the minutes nor the agenda notes of the meetings are in public domain. Following our letters along with TAC analysis in April 2011, addressed to Planning Commission, Union Ministry of Water Resources, Central Water Commission and members of the National Advisory Council, for the first time, TAC minutes were put up on CWC website (see: http://www.cwc.gov.in/main/webpages/TAC%20minutes.html). However, the last uploaded minutes were for the 115th meeting held in July 2012, after which minutes have stopped being uploaded. Secondly, some of the links are not working and all the files are unnecessarily large PDF files since only scanned pages of the minutes are put up, in place of the PDFs of normal word files, which would be of much smaller size. The TAC also has no independent, non government members, all the members are government officials. As we wrote to MoWR and Planning Commission in April 2011 and again in March 2014, there is urgent need for TAC to have  such members so that they provide objective perspective about the projects that come up before TAC.

The importance of functioning of this committee cannot be over emphasised. As we  wrote  in our letter to MoWR and Planning Commission, TAC “considers dozens of such projects with huge economic, social, environmental and other implications for the country in every one of its meetings. All of these projects are supposed to be public purpose projects, and are taken up using public resources. The Planning Commission accords investment clearance to the projects only after the TAC clearance. This Committee’s decisions are perhaps the ones which impact on India as a whole the most – as they relate to land and water – which are the basic life sustaining and livelihood providing resources for the people.”

It is high time that first effective steps are taken to ensure that the functioning of this committee becomes more transparent, participatory and accountable.
