A comparison of one- and two-dimensional model simulation of the Clyde Estuary, Glasgow
This paper evaluates one- and two-dimensional numerical models for the simulation of estuary hydrodynamics, in this case for the Clyde Estuary, Glasgow. The evaluation is based on identification of the relative strength and limitations of two commercial numerical models, namely ISIS 1-d and MIKE21. The estuary dynamic is analysed on meso-scale domain and over a few tidal periods. On such spatial and temporal scale, the water body is under dominant influence of tidal waves and surface runoff, but also affected by wind shear and atmospheric pressure. The Clyde estuary has a meso-tidal range and long-term average river inflow of 110 m3/s. Upstream of the city of Glasgow the estuary is fluvio dominant, but tidally dominant in the city centre and downstream of the city. The upstream reach is meandering in plan, and the downstream reach has a funnel shape of increasing width. Numerical simulations are conducted for several historical events. The relative influence of tides, storm surge, river inflow, precipitation, wind shear and air pressure is analysed. Predictions of water levels by numerical models are inter-compared and also compared to the recordings on several water gauging stations. A sensitivity analysis on the various tidal shapes, fresh water inflows, wind shear and air pressure are conducted.
