According to the previous studies of sediment carrying capacity, a new method of sediment carrying capacity on perturbed theory was proposed. By taking into account the average water depth, average flow velocity, settling velocity, and other influencing factors and introducing the median grain size as one main influencing factor in deriving the new formula, we established a new sediment carrying capacity formula. The coefficients were determined by the principle of dimensional analysis, multiple linear regression method, and the least square method. After that, the new formula was verified through measuring data of natural rivers and flume tests and comparing the verified results calculated by Cao Formula, Zhang Formula, Li Formula, Engelung-Hansen Formula, Ackers-White Formula, and Yang Formula. According to the compared results, it can be seen that the new method is of high accuracy.

Sediment Transport: Theory and Practice

Nearshore sediment transport is driven by the combined motions of water waves and currents. Due to the complications caused by orbital wave motion, methods developed for measuring sediment transport in largely unidirectional environments may not be applicable in measuring coastal sediment transport. To make matters even more complicated, the relatively orderly wave motion becomes disrupted by the extremely turbulent wave breaking at the transition between land and ocean, often referred to as the surf zone or breaker zone. In the following, the term nearshore is used in a general sense, representing a variety of coastal environments. Skip to main content Skip to table of contents.

Nearshore Sediment Transport Measurement

На высокой рабочей платформе-подиуме в центре комнаты возвышался Джабба, как король, отдающий распоряжения своим подданным. На экране за его спиной светилось сообщение, уже хорошо знакомое Сьюзан. Текст, набранный крупным шрифтом, точно на афише, зловеще взывал прямо над его головой: ТЕПЕРЬ ВАС МОЖЕТ СПАСТИ ТОЛЬКО ПРАВДА ВВЕДИТЕ КЛЮЧ_____ Словно в кошмарном сне Сьюзан шла вслед за Фонтейном к подиуму. Весь мир для нее превратился в одно смутное, медленно перемещающееся пятно. Увидев их, Джабба сразу превратился в разъяренного быка: - Я не зря создал систему фильтров.

Танкадо предложил бесценный математический метод, но зашифровал. Зашифровал, используя этот самый метод.

Однако номер пока не удалось узнать. - Двести два. Где это? - Где же на необъятных американских просторах прячется эта загадочная Северная Дакота. - Где-то поблизости от Вашингтона, округ Колумбия, сэр.
