Numerical modeling of the severn river bore propagation process

摘要：

　　Tidal bore is a series of waves propagating upstream with a sudden increase in flow depth that may form during spring conditions when the tidal range exceeds 4-6m.The Severn River bore is one of the most famous fluvial landmarks in Europe.This paper concentrates on numerical modeling of the Severn River bore propagation process.A hybrid of the two-dimensional Boussinesq-type model and the shallow water model is applied to simulate the Severn Bore, which is solved using a shock-capturing TVD (Total Variation Diminishing) Lax-Wendroff scheme.The numerical results are validated by some existing measurement data.The sensitivity of the Severn River propagation process to the river flow rate is studied.
