Question

For enhanced flood protection, NDMA is collaborating with the Ministry of Water Resources (MoWR) / Central Water Commission (CWC) and which other agency for River Bathymetric Survey and Digital Elevation Models?

• A. National Institute for Disaster Management (NIDM)
• B. Geological Survey of India (GSI)
• C. Survey of India
• D. Indian Meteorological Department (IMD)

Answer 1

Answer:

C. Survey of India

This collaborative effort is a strategic initiative to improve flood management in India.

• River Bathymetric Survey: This is the process of mapping the underwater topography of a river, including its depth, shape, and slope. It helps to understand the river's carrying capacity and how it behaves during floods.

• Digital Elevation Models (DEMs): These are 3D representations of a river basin's surface. By combining bathymetric data with land elevation, they provide a complete picture of the terrain.

The Survey of India brings its expertise in geospatial data and mapping to this partnership. The joint effort aims to create accurate, high-resolution maps of flood-prone river basins. This data is critical for developing more precise flood forecasts and early warning systems, which are essential for mitigating damage and saving lives.
