State wise rainfall Pre Monsoon 2020 & Post monsoon 2019

India Meteorological Department (IMD) divides a water year (June 1 to May 31) into four seasons: Monsoon: (June 1 to Sept 30), Post monsoon (Oct 1 to Dec 31), Winter (Jan 1 to Feb 28/9) and Pre Monsoon (March 1 to May 31). For rainfall during all these seasons, IMD’s hydro-meteorological website[i] provides a lot of data on daily basis, including daily district wise rainfall, state-wise, sub division wise and river wise daily rainfall maps among many other weekly, monthly and seasonal products. However, one problem with it is that none of this information is achieved. So if you missed seeing or downloading available data on any date, there is no way to look at it even next day. This is even true of the seasonal rainfall maps, unfortunately.

Most observers look at the monsoon rainfall data, which is clearly the most important season, without doubt. However, the rainfall in other seasons is also very important from a number of perspectives.

Here we are giving a detailed account of the pre-monsoon season rainfall that India received in the season just ended on May 31, 2020, including state wise, sub division wise, river wise and also district wise figures. Along with it, we also provide the figures of post monsoon figures for the just concluded water year. For the winter season (Jan-Feb 2020) we have only the figures for Jan 2020 since we missed downloading the Feb 2020 figures. We had already provided the monsoon 2019 figures through two blogs in October 2019[ii].

Chandigarh: Faidan Pind Drain Shows Ugly Side of ‘City Beautiful’

Union Territory of Chandigarh enjoys ‘City Beautiful’ tag for better planned urban development. Undoubtedly the city has wide roads, abundant green patches, well planned residential sectors, public amenities, cyclist tracks etc.; however dumping of solid waste and untreated sewage around its periphery shows that the city performs poorly in managing its water and natural sources.

The story of Faidan Nizampur also known as Faidan Pind drain near Airport is an apt example showing that while city manages to get beautiful tag, the rivulets and lives of people around it have turned miserable by increasing pollution load and other issues.

Satluj Basin

Shivalik Streams Going Going……..?

Several streams of Ghaggar and Sutlej river basins originate from Shivalik foothills lying in Haryana, Punjab state and Chandigarh union territory.  These rivulets along with main rivers have been facing threat from ever increasing industrial effluents and sewage loads. Moreover the degradation of catchment has transformed them from perennial to seasonal rivers.

Here is a short pictorial report showing pathetic situation of Markanda, Tangri, Sukhna, Kaushalaya and Patiala Ki Rao streams feeding Ghaggar and Sirsa river (a tributary of Sutlej) which over past few decades are abused as dumping ground of untreated industrial and domestic waste. At the same time there are revival hopes, if sincere restoration efforts are made.

CWC - Central Water Commission

Overview of CWC Flood Forecasting Sites 2019: North India

Flood forecasting is an important activity during monsoon, considering the huge and increasing flood prone area, flood frequency, intensity and flood damages. Accurate and timely flood forecasting can hugely help reduce the damages due to floods. Central Water Commission (CWC) is the only agency responsible for flood forecasting in India. To understand the CWC’s flood forecasting better, we have compiled the list of the various flood, inflow forecasting sites and flood monitoring sites in India.

In this compilation, we have given state wise list of CWC’s flood forecasting, flood monitoring and inflow forecasting sites in North India, comprising of states of Jammu & Kashmir, Punjab, Haryana, Himachal Pradesh, Uttarakhand, Uttar Pradesh, Delhi and Chandigarh. It includes available details like name of river, sub basin, Warning level (WL), Danger Level (DL), High Flood Level (HFL), Full Reservoir Level (FRL), Maximum Water Level (MWL), as applicable. As we see below, there are many gaps in this basic information for the sites that are part of CWC’s list. A similar zonewise overview of CWC’s sites was compiled in 2018, which can be seen here. Overview of CWC Flood Forecasting Sites 2018: North India. We have brought this updated compilation for 2019 as there are large number of changes as ou can see.

Chandigarh Water Sources; Streams: The City Not So Beautiful

Chandigarh is widely known for its well-designed urban areas and associated amenities. No doubt, the city is relatively congestion free and cleaner. The roads are wider, sideways have adequate space for walkers and cyclists and they are mostly covered under thick tree canopy earning its tag of ‘City Beautiful’.

However less is known about and rivers. This pictorial account tries to throw some light on present day situation of water sources like wells, ponds and rivers in and around Chandigarh town.
