Evaluation and comparison of the operational Bristol Channel Model storm surge suite

[摘要] A nested modeling system has been applied to Liverpool Bay to accurately simulate the circulation during the three month period January to March 2008. The model has been applied for a particle tracking study investigating the movement of 2 sediment mixes (70:30 silt to medium sand and 50:50 fine sand to medium sand) for 3 different deposit tonnages (10, 500 and 1500 Tonnes). The disposal sites are those already used for maintenance dredging within the Mersey Estuary: IS120 (close to the mouth), IS128 and IS110 (with increasing distance into the inner estuary). Following the release of sediment at the start of all the scenario simulations the majority (83% or more) of the deposited sediment remains within the Mersey Estuary after the 3 month simulation. A small percentage of fine particles (
