Watercourse and Reservoir Management

We provide surveying and digitization of watercourses and hydraulic structures. We develop digital terrain models of river channels and reservoirs. We deliver modern tools and high-accuracy data for inventory, monitoring, and effective management.

Mapping and Digitization

Mapping of river channels and hydraulic structures using remote sensing methods

Bathymetric surveys of watercourses (SONAR)

Digital terrain models of river channels and hydraulic structures

Data for hydrographic surveys, volume calculations, mathematical modelling, and other analyses

We perform bathymetric surveys and mapping of underwater terrain using advanced laser and sonar technologies. The data is used for applications such as river channel modelling, sedimentation monitoring, sediment volume calculations, and the assessment of reservoir capacity and retention, as well as flood risk analysis. Our services support water managers, municipalities, designers, and water authorities in obtaining accurate data for the effective management, maintenance, and development of watercourses and hydraulic structures.

Monitoring and measurement of the waterbed

Bathymetric Survey of Watercourses and Reservoirs

We use advanced, highly efficient LiDAR scanning methods (Riegl VQ-840) to capture the surrounding terrain, current water surface levels, and the bathymetry of the riverbed or reservoir floor. This approach enables coverage of large areas with survey-grade accuracy while significantly reducing data acquisition time. Detailed mapping of the underwater terrain is complemented by bathymetric surveys using a modern sonar system (Baywei M1), providing point densities in the order of hundreds per m² and penetration depths of up to 200 metres below the water surface.

Digital 3D Model of a River Channel

Our detailed mapping, including subsurface data, serves not only as a basis for asset inventory, profile generation, cross-sections, and volume calculations, but also enables the creation of a geodetically accurate 3D model of a river channel or hydraulic structure. The model visualizes the course of the water flow, the riverbed, bank edges, and other related features. Based on the accurate 3D model of a river channel or reservoir, we carry out advanced analyses and modelling, including flood risk assessment, inundation mapping, flow modelling, and sediment analysis.

Waterworks passport

When digitizing a waterworks, a construction passport or documentation of the actual construction is created. The process also includes the processing of operating and handling regulations, the alignment of plots in the real estate cadastre and the updating of geodetic and hydrogeological data. The depth and sedimentation of the bottom of reservoirs and streams are measured using sonar.

Flood risk analysis

Flood risk assessment

The digital twin of a waterworks allows for the modeling of various flood scenarios and the evaluation of their impacts on floodplains.

Municipalities and river managers can thus better prepare flood and emergency plans and minimize the risk of damage to property and infrastructure.

Early warning system

As part of the programs of the Ministry of the Environment, we offer technologies to support flood and drought measures – warning systems, digital flood plans, and prediction models.

Digital flood plans

Digital plans facilitate crisis management, coordination of emergency response units, and provide clear, easily updateable information.

Sediment Analysis and Volume Calculations

The geodetically accurate 3D model of the current riverbed or reservoir floor, obtained through bathymetric surveying, is compared with original, design, or reference bed conditions. Based on the resulting elevation difference model, it is possible to identify sediment deposition, bed erosion, as well as changes in channel morphology. Using volumetric calculations derived from the 3D model, we determine sediment volumes, dredged material quantities, and reservoir capacity and retention.
