WEST INDIA: Overview of CWC Flood Forecasting Sites

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 other sites, information is 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, in this article, we have given an overview of CWC’s flood forecasting and monitoring sites in West India. It includes state wise list of CWC’s Level Forecasting, Inflow Forecasting and level monitoring sites in 5 States in West India. Similar report has been published for North India[ii] and North East India[iii] and East India[iv] and South India[v]. This is the last part in the series. 

RAJASTHAN 

In Rajasthan, CWC has 33 sites including of 25 Level Monitoring and 8 Inflow Forecast sites. The state has no Level Forecast site. Out of 25 Level Monitoring site Mount Abu site is not active. Similarly HFL details and date is not given for 8 Level Monitoring sites though the hydrograph for the same sites are active.

The Bigod and Duplicate Old Bigod sites appear same. The hydrograph for Bigod is active and inactive for Duplicate Old Bigod. The HFL level for both sites is same but HFL date is different.  Similarly FRL and MWL information is incomplete for four Inflow Forecasting sites. The hydrographs for most Inflow Forecast sites have incomplete information.
