River Wise Rainfall in Monsoon 2019

Indian media never seems to report this, but IMD (India Meteorological Department) also provides river basin wise rainfall figures for South West Monsoon, also for other seasons. As in the previous years, here is an overview of the river basin wise rainfall during just concluded SW Monsoon 2019 (June-Sept 2019, though the monsoon started withdrawing only on Oct 9 and has not yet fully withdrawn from across India as I write this on Oct 15 2019), like the way we have been doing for the last three years[i]. Our earlier monsoon 2019 articles provided monsoon over view[ii], state wise rainfall figures[iii] and Marathwada specific situation[iv].

It’s not clear why Indian media does not report river basin wise rainfall figures, since that is arguably, the most appropriate way to look at the rainfall figures, since river basins are the hydrological units and the run off from the rainfall ends up in the rivers, and creates floods many times, as happened during 2019 monsoon. There could be issues of quality of the river basin wise rainfall figures, but that is true for all IMD’s rainfall figures at some level or other.

East India: 2019 Overview of CWC Flood Forecasting Sites 

Central Water Commission (CWC) is the only agency doing flood forecasting in India. CWC’s Flood Forecasting (FF) is available on its website[I]. 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 soon. East India includes five states: Bihar, Jharkhand, Chhatisgarh, Odisha and W Bengal.

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.
