Study of bank protection structures on the Kuma river in Stavropol Territory

Purpose: substantiation of the required width a stable channel while carrying out bank protection works on Kuma river near town Zelenokumsk Stavropol Territory. The analysis feeding conditions in design area is carried out, main reasons for erosion-accumulative processes central part Zelenokumsk, Territory are considered. Materials and methods. considered basin located two natural zones – foothills North Caucasus steppes Ciscaucasia, that affects groundwater feed flood regime warm season due to heavy rainfall. Spring not observed here gradual snow melting along high-altitude zones, therefore, there transition from winter runoff low period high-water-flood period. As result double feeding, originality water rivers formed, which spring floods, multi-peak summer floods autumn-winter low-water combined. Results. was checked by Altunin's recommendations, fastening options based available morphometric characteristics were assigned. Conclusions. gabion structure has an excellent quality stability, is, can help plant fixation or vegetation reproduction within structural frame. Root growth actually helps become more stable. Consequently, operation process such structures improves ecosystem. Besides, construction regulates environment terms climate humidity. A good effectively regulate velocity flowing water, increasing roughness, thus minimizing probability flooding.
