Krishna Prosad Mondal There is no direct satellite or remote sensing data that provides river depth measurements (also known as bathymetry) with high accuracy, especially for smaller rivers or complex, dynamic river systems like those in Bangladesh. However, several approaches utilize satellite data combined with other techniques to estimate river depths indirectly: 1:Satellite-Derived Bathymetry (SDB) 2: SAR (Synthetic Aperture Radar) 3: Altimetry Satellites (e.g., Jason-3, SWOT) 4: LiDAR (Light Detection and Ranging) 5: Multi-Sensor Approaches ,, Therefore, For accurate and detailed river depth data in Bangladesh, traditional methods like echo sounding or other in-situ techniques are still the most reliable. Satellite data can complement these methods by providing large-scale environmental context, monitoring changes over time, and helping to model depth variations indirectly.

If you're specifically interested in the potential applications in Bangladesh, you might look into ongoing projects or collaborations between local institutions and international bodies that are focused on using these technologies to monitor and manage river systems.
