Abstract

The relevance of this study is due to the increasing man-made stress on water bodies and the land resources connected with them within the urbanized territories, as a result, changes in the morphology and dynamics of river channels and floodplain. It leads to the need for an integrated environmental assessment of floodplain-riverbed complexes, especially small rivers within urbanized areas. The purpose of the study is an integrated environmental assessment of floodplain-channel complexes of small rivers in the city of Novosibirsk to substantiate the recommendations of engineering measures to reduce environmental tensions. The research results showed that the Yeltsovka and the Plyushchikha rivers belong to the group with weak environmental intensity, the Tula, the Yeltsovka-2, the Kamenka, the Kamyshenka are of medium environmental intensity, the Yeltsovka-1 is with strong environmental tension. Significance of the study is that the integral assessment of the floodplain-channel complex of small rivers in the city of Novosibirsk can be used to substantiate the recommendations of engineering measures to reduce environmental tensions, which should be selected based on the obtained integral points, as well as to prevent accidents at various facilities or communications during engineering construction or water engineering design, construction and operation.
