| Description | We study the cutoff Strážnický meander on the river Morava. Research is mostly based on continual groundwater level measurement. We focus deeply on this part from the methodological point of view and specific algorithm is presented, that can be used as an example for similar research in other localities. We analyze, how often the cutoff meander is connected to the active river channel and for how long part of a year is the meander connected at both ends, allowing water to flow freely in the abandoned channel. Due to a relatively dry period, that was observed in the locality in the last year, this did not happen very often. Further research was focused on estimating the sedimentation rate by generating cross sections from digital surface model in the interval of two years and also generating cross-sections with other geodetic measurements. The digital surface model was created by using the standard photogrammetric methods. The dominant process in the Strážnický meander is sedimentation, which however happens selectively, depending on the location in the meander. By analyzing sedimentary samples, the character of sedimentation was determined with regard on the specific location in the meander. |
