The first blog on just concluded South West Monsoon 2019, gave the national picture and broad picture of month wise, state wise, sub division wise and river wise rainfall. This blog provides some details of rainfall in districts of each of the 36 states and Union Territories (UTs) of India. Continue reading “Monsoon 2019: State wise rainfall”
As even NITI Aayog report acknowledged in June 2018[i], there is consensus that India is facing dire water crisis, which will only get worse. This was also predicted by the World Bank way back in their 2006 report called “India’s Turbulent Water Future”. But do we have the institutions that are capable of taking us out of this crisis? Remember the current institutes are at the root of our water crisis.
Imagine you have to forecast flood using a mathematical model run on a Pentium processor; or manage your office with typewriters instead of a desktop! How frustrating isn’t it, to manage an office with the near obsolete typewriter or run a flood forecasting model using outdated Pentium processor? Continue reading “Can Outdated Water Institutes steer India out of dire crisis?”
SYNOPSIS: Everyone concerned agrees that India is facing unprecedented and worsening water crisis. Some of the key aspects of water sector challenges include: Lack of reliable water information, need for restructuring of institutions, groundwater lifeline in distress, politicians and institutions pushing more large dams when evidence shows they do not work, the need for attention to maintenance of massive water infrastructure, the increasing footprint of Urban water sector, State of our rivers in general and Ganga in particular, water management for agriculture, governance and changing climate, among others. Unfortunately, these challenges do not seem to get reflected as electoral issues and all parties are equally to be blamed for this. The current Union government has very poor report card on almost every one of the water sector challenges, and its seems like a series of missed opportunities.

Two artists are engrossed in some meaningful graffiti work at a public bus stand, on an otherwise laid back, colourless Sunday morning. A closer look and their strokes in fact seem to be urging the passerby to pay attention to rivers and water resources. There seems to be a message to all the drawings. It is not often that one comes across a sight like this in small town Chalakudy in Kerala. The artists have teamed up with the Chalakudy River Protection Forum under the umbrella of a State-wide campaign titled ‘Ozhukanam Puzhakal’ or ‘The Rivers Must Flow’. Continue reading “Ozhukanam Puzhakal: UNTO HER WE SHALL RETURN…”
Kerala – the God’s own country is in strong grip of unsustainable sand mining which has been happening for decades in the rivers and coastal areas of the state. The state has suffered hugely in 2004 Tsunami and 2018 Floods which, as several reports explain, were aggravated by illegal sand extraction. Yet nothing seems to have changed. Apart from violation of environmental norms, the extraction of finite mineral is going on, ignoring the nature’s warnings.

The state of Kerala experienced extreme precipitation events during the 2018 South West monsoon period with multiple episodes culminating in devastating floods across the state during 14th-18th August 2018. This year, with an early onset of monsoons that dovetailed with strong summer showers, the state received about 41% excess rainfall (2394 mm against the normal of 1700 mm) during the period June 1st to August 22nd . Almost all of its reservoirs were near full storage by mid-July.
The heavy downpour and the uncontrolled opening of the spillway gates of almost all reservoirs that inundated huge stretches of river banks and floodplains, along with massive landslides across the Western Ghats affected more than 1.5 million people, with close to 500 human casualties, immense losses to property, livelihoods and resource security apart from the extensive damage to forests, wildlife and biodiversity. Maximum destruction was observed along the rivers of Periyar, Chalakudy and Pamba, all having multiple dams on their tributaries. The debate is still on as to the various reasons, both manmade and natural, behind the floods and the resultant wide-ranging casualties [2,3,4,5,6]. Meanwhile things have taken a rather unexpected turn in the flood ravaged state.

An Old Story: I read an account about Netherlands in the journal, Annals of Botany (2010)[i] . This story dates from the 11th century. Many centuries ago, the coastal plain of the Netherlands consisted of a dynamic landscape of meandering river channels, extensive floodplains and large complexes of fens and bogs. Sediment deposition and peat formation kept pace with the gradually rising sea level, so that the level of the land remained well above the water for most of the time. Since 11th century, inhabitants of the low-countries started to modify the hydrology of their surroundings to create protection from flooding for their dwellings and agricultural fields. They built dikes and started to manipulate the water level. Continue reading “Ithikkara River in Kerala: Tampering with Nature – a recipe for negative NPV”
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.

2018 becomes fifth year in a row when India’s south west monsoon has been below normal. In the beginning of monsoon season, Indian Meteorological Department (IMD) has forecasted rains to be normal with rainfall equal to 97 percent of the long term average. However at the end of the season the overall rainfall turned out to be 91 percent, with deficit of 9 percent at national level. However, as we see in this overview, the situation as move from national to local figures, is much different, mostly much worse.
According to IMD’s State Rainfall Map (cumulative) dated 30 Sept. 2018, the country received 804.0 mm rains against 887.5 mm of normal average. Thus the south west monsoon 2018 had 9.4 percent below normal rainfall.
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.
