Frequent 2024 Floods in Bhagalpur-Bihar
Guest Article by: Dr. Ruchi Shree
In 2024, Bihar received 19 percent less rainfall than the normal rainfall and one of its districts named Bhagalpur even lesser with 29 percent. From 1 June to October 21, this district of South Bihar situated on the banks of the Ganga received merely 713.8 mm rain while the expectation was 1054.3 mm according to India Meteorological Department figures. It is the third consecutive year when Bihar has received lesser rainfall than expectation[i] and it is likely to worsen the water scenario in the coming years. On the other hand, Bihar faced severe flood this year and Bhagalpur was one of its worst affected districts due to a rise in the level of the Ganga. In a span of around 45 days i.e. from mid-August to end of September, Bhagalpur faced floods four times. This writing is based on my observation of three locations in Nathnagar block of Bhagalpur — two villages named Dildarpur and Biharipur and the Tilka Manjhi Bhagalpur University (TMBU) premise (administrative wing and Lalbagh Professors’ Colony). TMBU is quite close to Dildarpur village (situated on the Diyara land between Champa Nalla/River and river Ganga).

(Feature Image: Yamuna river at Mawi site in Kairana, UP in Sept. 2024)
After remarkable deluge in 2023, the upper segment of Yamuna river has seen no significant flood spell all through the just concluded southwest monsoon 2024. This is unusual as the river generally witnesses at least a couple of low or medium flood spells in this segment every year.
However, this year the discharges from Hathnikund Barrage (HKB) in Haryana did not cross 1 lakh cusec figure even a single time. The peak discharge from the barrage was 87,017 cusecs at 06:00 hour on 26.09.2024.

(Feature Image: File photo of Yettinahole Project. Source: Daijiworld)
The Yettinahole project has seen protests and question marks right from the time when the project was proposed, none of them have been convincingly answered. As the Karnataka Chief Minister and his deputy commissioned a small part of it, those question marks remain as relevant today, including its hydrological viability, environmental impact assessments and sustainability, with hugely weakening of the western ghats by such major interventions without any credible impact assessments. (see: https://sandrp.in/2013/09/18/yettinahole-diversion-an-imprudent-rs-100-billion-proposition/)
It is good to see CWC and MoEF have also raised some questions and asked report even at this stage. One however expects CWC to raise such questions much earlier in the project cycle and before the project becomes fait accomplice. Else, it seems more like politicking. MoEF could have raised issues of violations before the violations happened on ground and should have refused to provide piece meal forest clearances as it has alleged.

The Union Government plan to spend Rs 2517 Cr in 2 years in seven metro cities to mitigate floods is certainly welcome announcement. The key component of the plan, conservation and improving capacity of urban water bodies is noteworthy along with storm water drainage. Does it mean that the River Front Development projects that actually reduce the flood carrying capacity of the rivers will be closed, since one does not expect govt to be working at cross purposes in different schemes.
In fact, Urban Water Sector as a whole needs attention with National Urban Water Policy as a first step. This is because the groundwater aquifers that are fast being emptied out, can be least cost option for storing the excess rain water, serving the purpose of reducing storm water drainage load and also improving water conservation. There is huge scope for this in all the seven metros listed in the scheme as also in many other cities.

Tripura is facing one of its worst floods, possibly worst since 1983, affecting all districts, at least since 19th August. South Tripura, Gomati and Unakoti are worst affected districts. According to latest estimates, at least 24 people have lost life with two more missing, 65400 people are in 450 relief camps, landslips at 2032 locations, 1.25 lakh ha crops submerged among other extensive damage. Total of around 1.7 million people or about 40% of state pulation are affected. 3 columns of army, 11 NDRF & 26 SDRF teams, 4 MI 17 helicopters and other emergency service teams are involved in rescue and relief works. The actual rainfall that started on Aug 19 gave enough warning for the state to prepare for the approaching disaster, but once again disaster management has failed to respond using this warning.

One of the heartening development this week is from Kerala, where Chalakudy river community held a satyagraha to demand proper integrated dam management plan in the Chalakudy River basin to minimize flood risks. It is rather rare that communities come out for such a demand. It was also great to see that the satyagraha was supported by Chalakudy Puzha Samrakshan Samiti, Chalakudy municipal chairman and also environmentalists.
The satyagraha in fact had specific demand for each of the dams included in the Paramibikulam Aliyar Project, including in Kerala and upstream Tamil Nadu. We hope the Kerala government positively responds to these demands at the earliest.
