A 1-dimensional (cross-sectionally averaged) model for application to : tidal- propagation, salinity intrusion, sediment and tracer distributions in estuaries.
CONCEPT/APPROACH Uses explicit finite-difference numerics , based on axial sections, to solve 1-D dynamical , continuity and conservation equations.
TIME-SPACE ENVIRONMENT APPLICABILITY Courant condition (Dx/Dt>(gH)½ ) for tidal propagation,Peclet condition (Dx/Dt>U) for conservation. Minimal computation effort allows simulations from days to centuries.
Best suited to meso/macro tidal estuaries (not stratified), finer suspended sediments, and tracers with flushing times/ half-lives > 6 hrs.
Intercomparisons wit analytical,2-D and 3-D simulation in EstProc (add ref)
DATA REQUIREMENTS Boundary Conditions:
Seawards : tidal heights Concentrations for marine tracers
Tidal limit: river flow Concentrations for fluvial tracers
Coefficients: Bed Friction, half-lives for tracers, erosion and deposition rates, axial dispersion rates
Validation, tidal heights/currents; salinity distribution,bathymetric adjustment rates
