Abstract
The article presents the concept, architecture and testing of mobile monitoring system of water reservoirs. Its main elements are a remotely controlled boat with a sonar, which additionally records GPS data. The developed system could be used in several configurations for the achievement of functions such as generating bathymetric maps or the current monitoring of the bottom of a water reservoir. The main functionalities of the system have been tested and presented with the results of the tests and their analysis, conclusions and plan of further development.
