What happened

Key facts

  • The Bihar Cabinet approved a proposal for an MoU between the state Water Resources Department and the National Institute of Hydrology in Roorkee for a flood-plain zone delineation study (per The New Indian Express).
  • The study is estimated to cost Rs 1.99 crore (per The New Indian Express).
  • The study will identify and map flood-prone areas along the Kosi, Gandak and Sone rivers (per The New Indian Express).
  • The study is intended to support sustainable development in flood-affected areas and minimise loss of life and property (per The New Indian Express).
  • Cabinet Secretariat Department Additional Chief Secretary Arvind Kumar Chaudhary said the study would support balanced development in changing environmental and socio-economic conditions (per The New Indian Express).
  • The Bihar Cabinet also approved a scheme estimated at Rs 8.39 crore to assess the safety and condition of 24 dams under the Dam Safety Act, 2021 (per The New Indian Express).
  • The New Indian Express reported that floods had affected 15 Bihar districts after heavy rainfall in neighbouring Nepal, affecting more than 50 lakh people, with floodwaters entering homes and damaging standing crops (per The New Indian Express).

The brief

The Bihar Cabinet approved a proposal for the state Water Resources Department to sign a memorandum of understanding with the National Institute of Hydrology in Roorkee for a flood-plain zone delineation study. The New Indian Express reported that the study is estimated to cost Rs 1.99 crore and will identify and map flood-prone areas along the Kosi, Gandak and Sone rivers.

The study is intended to support sustainable development in flood-affected areas and minimise loss of life and property. Cabinet Secretariat Department Additional Chief Secretary Arvind Kumar Chaudhary said it would help guide balanced development in light of changing environmental and socio-economic conditions.

The report also described the proposal as serving the public interest. The Cabinet approved a separate scheme to assess the safety and condition of 24 dams under the Dam Safety Act, 2021. The scheme is estimated to cost Rs 8.39 crore, and the government has set a target of completing it within eight months, according to The New Indian Express.

The newspaper placed the Cabinet decisions in the context of recent flooding in Bihar. It reported that floods affected 15 districts after heavy rainfall in neighbouring Nepal. More than 50 lakh people were affected, the outlet said, with floodwaters entering homes and damaging standing crops.

The Cabinet’s approvals therefore include both mapping flood-prone river areas and inspecting existing dams. The account links the river study to development planning and reducing losses, while describing the dam scheme as an assessment of safety and condition; it does not provide further implementation details for either project.

The National Institute of Hydrology, Roorkee, is the proposed partner for the river study, while the Water Resources Department is the state department named in the proposed MoU. The reported approval is for the proposal to sign the agreement, not a statement that the study has already been completed.

The dam scheme has a stated completion target, but the account gives no comparable schedule for the river mapping study.

Why it matters

  • Floodwaters entered homes and damaged standing crops in Bihar; The New Indian Express said more than 50 lakh people across 15 districts were affected.
  • The proposed Rs 1.99 crore study focuses on mapping flood-prone areas along the Kosi, Gandak and Sone rivers, with the stated aim of supporting development and reducing loss of life and property.
  • The Rs 8.39 crore dam scheme covers safety and condition assessments of 24 dams under the Dam Safety Act, 2021.

What to watch next

  • Whether the Bihar Water Resources Department signs the proposed MoU with the National Institute of Hydrology in Roorkee.
  • Whether the river delineation study maps flood-prone areas along the Kosi, Gandak and Sone rivers as described.
  • Whether the dam-assessment scheme is completed within its stated eight-month target.

How we got here

The Kosi breach near Kusaha, Nepal, on 18 August 2008 redirected the river through an old course and caused widespread flooding in north Bihar.

The breach followed years of pressure on the river’s embankments and difficulties maintaining them across the Nepal–India border; the Kosi project was governed by agreements between the two countries, including the 1954 Kosi Agreement and its 1966 revision. Bihar’s flood risk is shaped by rivers that rise in Nepal and flow across the state’s low-lying northern plains.
