Bathymetric & Hydrographic surveys of dams, rivers and reservoirs.
We are proud to be the only company in South Africa offering sub-surface sonar services utilising unmanned surface vessels (USVs).
This innovative approach not only enhances the precision of our bathymetric surveys but also significantly reduces operational risks by minimising human exposure in challenging marine environments.
Survey Types
Topographical Survey Underneath Water
We conduct detailed topographical surveys beneath water to map underwater features and terrain. Using advanced sonar and hydrographic equipment, we provide accurate data for dam construction, dredging, and environmental studies. These surveys are essential for understanding underwater conditions and planning aquatic or infrastructure projects.
3D Scanning of Surface
Our 3D surface scanning services capture highly accurate and detailed models of land surfaces. These scans are ideal for analyzing site conditions, monitoring changes, and visualizing complex landscapes. They provide critical input for engineering, construction, and environmental management.
Combine It with an Aerial Survey for Easy Reference and Display Purposes
We enhance our survey results by integrating 3D scanning and topographical data with aerial surveys. This combination provides a comprehensive view of the project area, offering easy reference and visually rich displays. It’s a powerful tool for presentations, planning, and stakeholder engagement.
Calculations Services Include:
Stage Discharge Relationship
We calculate the relationship between water stage (height) and discharge (flow rate) for streams, rivers, and reservoirs. This information is critical for managing water resources, flood control, and hydraulic engineering projects. Accurate calculations help optimize water management strategies.
Dam Level to Capacity
We provide precise calculations of dam levels in relation to storage capacity. This data is essential for managing water storage, ensuring safety, and planning for overflow scenarios. Our calculations help in decision-making for irrigation, hydroelectric power, and flood control.
Depth and Area of Dam to Overflow
Our services determine the depth and surface area of a dam at various levels, including the point of overflow. This helps predict overflow scenarios, manage capacity, and assess the dam’s performance under different conditions. Accurate measurements are crucial for operational safety and risk management.
Sludge/Sediment Content
We calculate the volume of sludge or sediment accumulated in dams, reservoirs, or ponds. This data helps plan maintenance, dredging, and capacity restoration efforts. Understanding sediment content ensures efficient management of water storage and quality.
Flow Rate for Discharge and Inflow:
Our team measures and calculates the flow rate of water entering and leaving a system, such as a dam or river. These calculations are critical for water balance assessments, flood predictions, and infrastructure design. Accurate flow rate data supports effective water resource management.
