摘要

In the digital age, spatial databases are the main source of information on the hydrographic network. However, the main challenge remains the need for frequent updates alongside the accurate presentation of current and potential coverage. Modern geo-information tools based on the processing of remotely sensed materials allow precise modeling of places where reservoirs historically occurred or are predisposed to form. The restoration of reservoirs is significant in the context of flood protection, the improvement of retention conditions, and the development of blue-green infrastructure. It is also much more economically viable than preparing sites for new construction. The missing element in the systematic use of the aforementioned materials and tools for these purposes is methodology. For this reason, in this article, based on images and a point cloud acquired during a photogrammetric aerial flight, five methods are tested, and the most effective method is identified, depending on the intended application.
