The paper presents the lowland accumulations in Timiș County and the purpose for which they were executed. As a result of heavy rains and runoff on the slopes, in Timis County, dozens of settlements were affected by floods, people were evacuated, homes, yards, cellars, streets, roads and even agricultural land were flooded. In order to ensure better protection against floods, in order to be able to cope with the consequences of floods, both on agricultural lands and for settlements related to watercourses, lowland accumulations have been set up. The accumulations are non-permanent and are arranged on poorly productive land with the capacity to retain large volumes of water. Floods are a natural phenomenon, nowhere in the world is there a zero risk of flooding. Land improvement works, including those for flood protection and drainage, began about 150 years ago in the surrounding area of Timisoara and its rivers, which was mostly swampy and muddy. Starting with the 18th century, impressive hydrotechnical works were started for sanitation, dams (creation of lowland accumulations) and even drainage. In parallel with the flood protection works, activities were also conducted to improve navigation, to supply the city of Timisoara with drinking water, as well as for industrial purposes. Many of these hydrotechnical works were modern in their time, in which he collaborated with famous specialists of the time, including the Dutchman Maximilian Emmanuel de Fremaut. In the 1970s, a number of hydrotechnical structures were designed, consisting of low-lying accumulations to accumulate water during floods, lowering the level of flooding downstream, and thus reducing the destructive effects of flooding. The paper presents a part of the hydrotechnical structures from the Timiş County river basin, which includes the following structures: 9 permanent accumulations, 12 non-permanent accumulations, 3 transfer channels in the nearby basins, 970 km of dams of which: 824 km on Timiş and 146 km on Bega (as part of the Timiş - Bega interconnection), 4 polders, 1 hydrotechnical node (water distribution structure). Starting with the area from Lugoj, the character of Timiş changes from a steep slope river to a river with plain characteristics, also from here begins the dammed part of the river considerable damage is avoided.
