Abstract

Measurement of hydrodynamic conditions, sediment transport and bed morphology in a tidal inlet J.J. Williams, P.S. Bell & P.O. Thome Centre for Coastal and Marine Sciences, Proudman Oceanographic Laboratory, Bidston Observatory, Bidston Hill, Prenton CH64 7RA, UK Abstract In many tidal inlets strong tidal currents and/or large waves generally prevent the deployment of instrumentation using benthic frames or boats and consequently measurements of hydrodynamic and sediment parameters necessary for calibrating numerical models remain scarce. Recently a solution to this problem has been found using a multi-sensor instrument deployed from a small 'jack-up' barge. Observations demonstrating successfully the acquisition of a range of hydrodynamic and sedimentological data are presented. 1 Introduction As part of the International Project INDIA (Inlet Dynamics Initiative: Algarve), fieldwork has been undertaken in the Barra Nova tidal inlet located in southern Portugal (Figure 1),
