| Anotation | The aim of the project is the development and validation of methods and techniques for effective combination of terrain measurements together with the measurement data of the surface water bodies (channels and reservoirs morphology) so that there is as accurate and comprehensive data on the use in the area of environmental protection and population, and socio-economic infrastructure protection including areas of emergency planning and management. There is now no doubt that GIS tools and mathematical modeling support activities such as the creation of flood plans, water management systems, operational hydrologic forecasting service (HPPS CR) or water erosion analyses more effective. Nevertheless, the quality of these outputs for decision support in emergency situations, among others, is directly proportional to the quality and timeliness of input data. Bathymetric data obtained from field measurements are at significantly lower density and actuality due to the dynamics of the river channels bottom, have a low interoperability and as such, adversely affect the accuracy of the GIS and models outputs. The project aims to test various types of measurements to obtain morphological and other information on water bodies, development of procedures and methods for their combination with other available data sources, and furthermore their verification using hydraulic models using industrial standards and finally visualization of results. The resulting geodata help reduce uncertainty in GIS and hydraulic models simulations, and also contribute to understanding the dynamics of bodies in the temporal and spatial context. In this regard, an important attribute is therefore the use of these devices and methods, to obtain large amounts of data in short time horizons and with the rational economical costs. Another important aspect is the possibility of combining these data with traditional geodetic methods of river channels which haven't been routinely used and documented yet. |
