SPECIALIZED ENGINEERING APPLICATION

Cross-Section Survey (River/Channel)

Channel Profile Mapping: Measuring underwater bathymetric profiles and above-water bank elevations at defined cross-section intervals along rivers, canals, and drainage channels. Hydraulic & Flood Modeling Support: Gathering accurate geometric profile datasets required for hydrodynamic river flow modeling, flood risk assessment, and capacity analysis. Navigational Channel Audits: Measuring operational channel width, minimum draft clearance, sedimentation buildup, and bank slope stability for safe vessel navigation. Dredging & Erosion Volumetrics: Computing precise cross-sectional area changes to determine sediment siltation rates, bank erosion, and accurate dredging cut volumes.
