The erosion generated by water, called synthetically water erosion, especially caused by the stream of water induces, the continuous change of the watercourse with significant imbalances of form and path, but also if it is the aquatic ecosystem, or a series of many others negative changes in the riparian areas of the minor riverbed, with material damage and sometimes clear loss of human lives. In time, constructive measures have been developed and applied, located in the riverbeds, to manage and minimize the impact of this phenomenon. The monitoring of the behavior of these works shows the beneficial effect on the limitation of erosion, but it also reveals the negative effects of the hydrodynamic action of the water on their structure and stability, eventually on their durability. The present paper proposes a synthetic analysis of the causes and ways of degradation of the main types of works used in engineering practice to limit the erosion of the watercourses. The analysis is based on an extensive documentary and field study carried out on concrete cases, on a series of rivers in the river basins of Moldova. The causes that led to the observed degradation are highlighted, respectively the solutions by which these shortcomings could be avoided in the future. It highlights the increased efficiency and the longer life of the new types of works used for this purpose, respectively the works based on the use of geocontainers.
