Unconventional High Precision Micronetwork Determination for the Needs of the Monitoring of the Riverbed Model Changes Caused by the Water Flow

Popis výsledku v původním jazyce

The article presents a design of the geodetic measurement, measurement itself, the results and their interpretation for the specific water management experiment. The experiment consists of the monitoring of the changes of the riverbed caused by the water flow with maximum permissible error 2 mm. For purposes of the research project “Improvement of navigation conditions on the Labe between Ústí nad Labem - state border CR / FRG - Navigation Step Děčín” was built a model for the water of the Elbe River with a total length of 7 km at a scale of 1:70 in outdoor areas of the Water Research Institute T.G.M. Prague (Czech Republic) in 2015. The length of the model is 100 m. The ultimate goal of the project is the design and realization of the river regulation to improve the navigation conditions, the impact of adaptations will be tested on the specified physical model first. The model is concrete, the riverbed itself is modeled from the sand with grain size corresponding to the real bottom cover (in scale 1:70). Whole model is covered by the wooden roof from above and by the dense mesh-work from the sides to avoid the damage of the riverbed by the weather or small animals. The watercourse is considerably tortuous and measurement situation is thus approaching to the measurements in a narrow tunnel (width of about 2 m). The task of the presented geodetic measurement is to determine the coordinates of spherical control points for subsequent 3D scanning with a standard deviation in each coordinate better than 0.4 mm. Changes in the riverbed are then monitored by the 3D scanning method. The objective was successfully achieved by a special shape surveying network designed a priori in precision planning software PrecisPlanner 3D and using high-precision instrument and equipment.
