МНОГОЛЕТНЯЯ ИЗМЕНЧИВОСТЬ МОРФОМЕТРИЧЕСКИХ ХАРАКТЕРИСТИК ЧАШИ НОВОСИБИРСКОГО ВОДОХРАНИЛИЩА

Аннотация

Erosion and abrasion play the main role in the relief formation and sedimentation in the basin of Novosibirsk Reservoir. These processes caused important changes of morphometric characteristics of the basin. For instance, the average thickness of accreted sediments has reached 0.94 m, the Reservoir total capacity has reduced by 1.02 km³, its average and maximum depth and water area have diminished notably, but average and maximum width have increased. The shoreline length, the number and area of island have changed too. The character of these changes is similar to changes in other reservoirs of this type.
