Flood Forecasting (FF) is one of the important activities of Central Water Commission (CWC), which is undergoing expansion and improvement, but there is still a huge scope for improvement. 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 South India, the last region to be covered for 2019 flood season. It includes state wise list of CWC’s Level Forecast, Inflow Forecast and level monitoring sites in South Indian states of Andhra Pradesh, Telangana, Karnataka, Tamil Nadu, Puducherry (no FF sites) and Kerala. Similar report has been published for North India[i] and North East India[ii], East India[iii] and West India[iv].
ANDHRA PRADESH In 2018, CWC’s FF website had 42 sites from Andhra Pradesh comprising of 11 Level Forecasting, 18 Level Monitoring and 13 Inflow Forecasting sites. The CWC has added 13 more sites including 12 Level Monitoring and 1 Inflow Forecasting site. So, now the state has 52 Flood Forecasting sites of which 10 are Level Forecasting, 31 are Level Monitoring and 11 Inflow Forecasting. The total count excludes Rajahmundry Level Forecasting and Srisailam dam, Prakasam Inflow Forecasting sites as these are repeated, out of which Rajamundry and Srisailam were counted twice last year, now it is counted once. Polavaram site was listed as Inflow forecasting site, it has now been listed as level monitoring site.
HFL date for 4 Level Forecast (Godavari Bridge, Chinturu, Avanigadda and Nellore Anicut) and 2 Level Monitoring sites (Vijaywada and Keesara) is not mentioned though HFL level is given. HFL level and date has been now mentioned for Atreyapuram Level Forecast site. Similarly HFL level has been given for Chinturu Level Forecast site but date is still missing. Hydrographs for 2 Inflow Forecasting sites Indira Sagar Project and Priyadarshini Jurala Project are inactive.

Sakmur/Sirpur and Sirpur (T) sites appear same as HFL level for both are same. While Sakmur/Sirpur is Level Monitoring site, Sirpur (T) is Level Forecast site. Hydrograph for Sirpur (T) is inactive but active for Sakmur/Sirpur site.
Sangam and Sangam (Kinnerasani) sites appear same. Both have same HFL level and date with active hydrographs but are shown on different rivers.
HFL detail and date have been included for Sakmur/Sirpur and K. Agraharam sites now. Wadenepally Level Monitoring site has HFL level but date is still not there. Sripada Yellampalli Project Inflow Forecast site lacks FRL, MWL detail with hydrograph also inactive; whereas 3 other sites Sripada Yellampalli Project, Koddam dam and P.D.

KARNATAKA In 2018, CWC’s FF website had 59 sites from Karnataka comprising of 1 Level Forecasting, 46 Level Monitoring and 12 Inflow Forecasting sites. In 2019, 18 sites has been added by CWC. These include 10 Level Forecasting (these 10 sites were basically Level Monitoring sites which are now turned into Level Forecasting with DL, WL details), 6 Level Monitoring and 2 Inflow Forecasting sites. Overall, there are 67 sites from Karnataka including 11 Level Forecasting, 42 Level Monitoring and 14 Inflow Forecasting sites.
CWC has not added HFL date for 4 Level Forecasting and 5 Level Monitoring sites though HFL is given for all these sites. Honnali Level Monitoring site on Tungabhadra river has been removed now.
MWL detail is missing for 5 Inflow Forecasting sites. 3 Inflow Forecasting sites namely Upper Tunga Project repeated as Airani, Narayanpur Dam and Tungabhadra dam are repeated hence excluded from overall tally in analysis.
Tributaries of Krishna and Cauvery has crossed HFL at many sites e.g. THORESHETTAHALLI, T.K. HALLI in 2019 monsoon. Names of several districts are mentioned twice under List Based Selection category.
Screen shot shows names of repeated districts in the state.

KERALA In 2018, CWC FF Website had no Level or Inflow Forecasting sites. There were only 22 Level Monitoring sites. In 2019, CWC has added 4 Level Forecasting sites; 3 of which NEELEESWARAM, KUMBIDI, MALAKKARA were earlier Level Monitoring sites. 16 new Level Monitoring sites and 2 Inflow Forecasting sites has also been added in the state. Now CWC has 41 sites from Kerala, including 4 Level Forecasting sites, 35 Level Monitoring sites and 2 inflow forecasting sites.
Out of total 39 Level Forecasting and Monitoring sites, for 21 new HFL was attained in Aug. 2018. Out of total 35 Level Monitoring sites 14 sites lack HFL detail including 4 sites which have HFL level but not the attaining date. Rivers names for 3 sites ARKKANNUR, Nellipalli and MOTTAPURAM are not mentioned. Hydrographs for both Inflow Forecasting sites are not updated properly.
New HFL details for PUDUR site is given as 65.14 dated 16-08-2018 which is less than 65.55 m mentioned earlier.

Slideshow on inactive, incomplete hydrographs from Kerala state.
Tamil Nadu In 2018, CWC’s FF Website had 65 sites from Tamil Nadu comprising of 3 Level Forecasting, 48 Level Monitoring and 14 Inflow Forecasting sites. In 2019, CWC has included 5 Level Forecasting sites (of which 2, BILIGUNDULU and URACHIKOTTAI were earlier Level Monitoring sites), 11 Level Monitoring sites in the state.
CWC has removed 2 Level Monitoring Lower Anicut, ASHRAMAM and 1 Inflow Forecast site Sathanur dam (which was repeated). Similarly Balasamudram (new added), KALLIDAIKURICHII, IRRUKKANKUDI Level Monitoring and Gomukhi Dam Inflow Forecasting sites are repeated. Hence these are not included in final counting.
So, now there are a total 74 sites including 8 Level Forecasting, 54 Level Monitoring and 12 Inflow Forecasting sites.
In Level Forecasting sites, HFL date for 3 sites BILIGUNDULU, PALLIPALAYAM and BHAVANI BRIDGE are not given. In Level Monitoring sites, Hydrographs of 7 sites are inactive while 5 sites with HFL detail lacks HFL date. Similarly HFL details of 5 sites NELLITHURAI, SEVANUR, THENGUMARAHADA, ELUNUTHIMANGALAM, THOPPUR has been changed. GUMMANUR site HFL details has been removed and HFL details for 2 sites MURAPPANADU and KUZHITHURAI has been included. LAKSHMANANPATTI site river name is changed from Moyar to Kodavanar while river name for THIRUVATTAR site is not mentioned.
Among Inflow Forecasting sites, MWL detailed is given for only 1 site out of 12 and 4 sites even lack FRL detail. As usual names of most of the districts are repeated unnecessarily and hydrographs from most of the Inflow Forecasting sites are not updated.
Screen shot shows names of repeated districts in the Tamil Nadu state.
