| Popis: | To ensure navigable depths in the problem area Gorodets - Nizhny Novgorod, significant dredging is required to develop almost all the riffles in the area. However, the sandy soils that make up the channel will lead to a significant sinking of the soil into the shipping channels, which will require additional dredging during the summer-autumn period when the water is low. Factors influencing a significant change in the site are: 1) exhausted hydraulic capacity of the river; 2) the influence of features associated with the location of the site within the lower pool of the Nizhny Novgorod hydroelectric power station. The transferred calculations based on channel survey plans and the analytical method give comparable results. |
