2022: CWC Flood Monitoring Sites in East India

Flood forecast and monitoring is essential part of Central Water Commission’s (CWC) work. Presently, the agency claims[I] issuing flood forecasts at 332 sites including 133 Inflow Forecast (IF) sites and 199 Level Forecast (LF) sites. Since 2018, SANDRP has been presenting critical analysis of CWC’s flood forecast website[II] in region wise manner.

In 2022 SW monsoon season, we have already published the overviews for North[III] and North East[IV] regions of the country. This third part in the series covers the states in East India including Bihar, Jharkhand, Chhattisgarh, Odisha and West Bengal (Ganga Basin).

DRP NB 120922: Decisive judicial action dire necessity for wetlands

( Feature Image:- Satish Acharya’s illustration on Bengaluru floods: Whose land is it anyway? 07 Sept. 2022)

The wetlands reports tell us a lot, but the key point is that decisive judicial action is necessary if our wetlands are to have any future. The directions of the Tamil Nadu High Court to geo reference all wetlands of Tamil Nadu, including small (Less than 2.25 ha area) is good beginning, but the court will need to ensure continuous monitoring and ensure implementation. Because the past shows that the government and other stakeholders have collectively failed to take any decisive action to save our wetlands. The disastrous results are evident at so many places, this week it is most clear from the flooding of Bangalore, mainly due to encroachment of lakes, wetlands, water channels and their catchments.

Monsoon 2022: CWC Changing HFLs in Ad-hock Manner

During monsoon season, Centre Water Commission’s (CWC) carries flood monitoring and forecast work through a network of 332 stations[i] covering 20 major river basins. The stations are comprised of Level Forecast (LF), Level Monitoring (LM) and Inflow Forecast (IF) sites. The LF sites have Warning Level (WL), Danger Level (DL), Highest Flood Level (HFL), date of HFL information while LM sites maintain HFL and HFL date records. At IF sites flood level for respective dams/ barrages with inflow, out flow figures are measured and forecast is issued accordingly.

However, there are plenty of concerns plaguing CWC’s flood forecast and monitoring work across country for years. In this 2022 SW monsoon season, the agency has exhibited one more problematic tendency which exhibits not only its careless approach vis-a-vis keeping accurate information of HFL breach events, but it also seems strange that it realises it has giving wrong HFL level and date information mostly only after crossing the HFL now.

During monsoon CWC (Central Water Commission) monitors water level at several hundred sites in the county and publishes this information on its Flood Forecast 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 listed on the website.

Since 2018, SANDRP has been analyzing CWC’s flood forecast website in zone wise manner.
