In this paper, models of wave formation and sediments transportation at the shoreline of Novosibirsk reservoir are presented. The models are utilized to calculate wave parameters for the four sections of the reservoir shoreline segment at p. Bystrovka, Iskitim district of Novosibirsk region. The average annual wind duration data for active rhumbs are obtained from Ordynskoe Hydrometeostation. Annual capacities of sand sediments flows are calculated for each site with different grain sizes and different values of longshore sediment flow specific deficit (proficit) for the period from 1990 to 2010. The calculations are performed in the application «Coastal Engineering Calculator» (developed in the Institute of Water and Environmental Problems SB RAS).
Results of the calculation are analyzed and compared with similar data for the period from 1959 to 1986. Average annual capacities of sediments flows for the period from 1959 to 1986 are reported to be several times higher and have the opposite direction than the calculated capacities for the period from 1990 to 2010. Analysis of the longshore sediment flow specific deficit dynamics demonstrates changes of the longshore coast from erosion to slight sediment accumulation. In the conclusion, slowing of morphodynamic processes at the shoreline of Novosibirsk reservoir near Bystrovka is outlined.
