Service Details:

River Surveys are required by clients for various reasons examples flood relief schemes, cause of flooding and pipeline crossings. ASC Group have been involved in numerous river surveys and generally this involves surveying a river along a particular length and producing a topographical survey in plan plus cross-sections of the river profile at intervals determined by the client. We utilize Depth sounding equipment where depth is not calculable by traditional surveying methods.

Bathymetric Survey Services involve the measurement and mapping of underwater depths and seabed features of water bodies such as rivers, lakes, reservoirs, canals, harbors, and coastal areas. These surveys provide accurate information about underwater topography, sediment levels, and channel geometry, which is essential for planning, design, and maintenance of hydraulic and marine structures.

Bathymetric surveys are carried out using advanced echo sounders, GPS positioning systems, and data processing software to generate precise depth profiles and contour maps. The collected data helps assess water depth variations, siltation patterns, and potential obstructions below the water surface.

Applications:

• River, lake, and reservoir depth mapping

• Siltation and sedimentation studies

• Design and maintenance of dams, barrages, and canals

• Port, harbor, and jetty planning

• Navigation channel assessment

• Flood modeling and hydraulic studies

Techniques & Equipment:

• Single-beam or multi-beam echo sounders

• Differential GPS / RTK-GPS for accurate positioning

• Integrated hydrographic survey systems

• Data processing and contour mapping software

Benefits:

• Accurate underwater terrain mapping

• Non-intrusive and efficient data collection

• Supports dredging and desilting planning

• Enhances safety and navigation efficiency

• Provides reliable data for engineering and environmental studies
