Hydrology

Air Laser Scanning Technology and its implementation by our company on the Polish market has caused a revolution in the field of hydrodynamic modelling. At a time when human safety and property protection from flooding has become a priority, the information about digital terrain model is one of the most important in the process of creating flood risk maps. It turned out that particularly important factors were the accuracy and timeliness of information about the natural topography which determines the direction of the water flow. In addition, the data from the air laser scanning in the form of point cloud allow the analysis of land cover characteristics that determine resistance to water flow presented in the form of the bedrock roughness maps. Standard aerial photographs are also useful during the inspection of the condition of river beds and inter-embankment zones.
