Today at a glance — things to remember
Nadi Sanjeevani: river silt to be used in Bihar highways; MoU between NHAI and Bihar (3 Nov 2026).
Bihar claims to be the first state with a comprehensive silt management policy (2026).
Four Bihar road projects worth ₹49,751 crore have cleared PPPAC; now await CCEA.
Patna-Purnia greenfield expressway is the biggest at ₹31,987 crore.
Four-line rail bridge over the Sone at Koilwar approved, estimated at ₹3,500 crore.
On 3 Nov 2026 in New Delhi, an MoU between NHAI and the Bihar government was signed in the presence of CM Samrat Choudhary and Union Minister Nitin Gadkari to dredge river silt and use it in highway construction.
Key facts
About 83.5 million cubic metres of silt to be used across 27 road projects in Bihar.
24.3 million cubic metres to be given free of cost to 16 ongoing NH projects.
Linked to the Bihar Water Source Restoration and Silt Management Policy 2026; Bihar calls itself the first state with such a policy.
CM said silt deposits are up to 10 metres thick; Ganga widens to 38-40 km near Katihar-Bhagalpur.
39 NHAI projects (about 1,561 km, ₹58,340 crore) are under way in Bihar.
Way forward
Pair desilting with scientific sediment budgeting, river-wise dredging plans and ecological safeguards so that channels regain carrying capacity without harming aquatic life.
Concept
Silt raises river beds, shrinks channel capacity and worsens floods. The Kosi ("Sorrow of Bihar") carries one of the highest sediment loads. The Chitale Committee (2016) studied desiltation of the Ganga up to Farakka.

8. State of the Cryosphere 2026: overshooting 1.5°C risks permanent ice loss
Released on 2 Nov 2026 by ICCI and UNEP ahead of COP31 (Antalya, 9-20 Nov), the reports warn that even a temporary overshoot of 1.5°C may cause irreversible damage to ice.

Q. Silt is the hidden multiplier of floods in Bihar. Critically examine how the Bihar Water Source Restoration and Silt Management Policy 2026 and the 'Nadi Sanjeevani' initiative can help flood management in the Kosi-Gandak-Ganga basin. (BPSC Mains GS-II, 38 marks)
Hint / approach
Intro: Bihar's flood-prone area and Himalayan rivers from Nepal. Body: silt (Kosi, Farakka backflow, 10 m deposits), policy features (83.5 mn m³ silt in 27 road projects), benefits (channel capacity, cheaper roads, land reclamation), concerns (ecology, sand mining misuse, Nepal cooperation). Way forward: sediment budgeting, Chitale Committee ideas, India-Nepal basin management.
