sedimentary budget造句

• To assess the sedimentary budget the coast has to be divided into two separate morphologies, commonly known as littoral cells and compartments.
• When a coastal environment is in sediment deficit, anthropogenic sediment nourishment is one way in which a balanced sedimentary budget can be maintained.
• Sedimentary budgets are used to assist in the management of beach erosion by trying to show the present sediment movement and forecast future sediment movement.
• Models have been developed for measuring longshore drift which can assist in determining a sedimentary budget, if they are integrated over the correct timescale.
• Sediment supply is now almost zero which has produced a significant imbalance to the near shore sedimentary budget, creating major erosion and shifting of sediment along the coast.
• Anthropogenic activities can also influence sedimentary budgets; in particular damming of a river and in stream gravel mining of a river bed can reduce the sediment source to the coast.
• Nourishment of a coast can be regarded as a fast fix option to reversing a sediment deficit; however, it is important that nourishment is on-going in order to ensure the sedimentary budget remains balanced.
