Применение расчетного (энергетического) метода к оценке возраста береговой линии моря Лаптевых в Ванькиной губе

Аннотация

The moments, when the shoreline has not yet got and already got its present position, are assumed to be dated by age of spits situated within the bay and its inlets at various height from 0 to 10 meters a. s. 1. The spits age defined as time interval which is necessary for the spit accumulation was calculated on the base of the spit volume and energy, duration, and frequency of sediment-moving waves within the bay. The calculation was complicated by special hydrological conditions of the bay, by very high level of storm surges in particular. An uncontradictory time series has been deduced, its average values being from 7,5 to 1,5 thousand years. The reference sea level at the Vankina Guba bay rose for two meters within the time interval.
