Abstract
Existing boat-based methods are unable to measure current fields with sufficient spatial coverage for accurate modelling of hydrodynamic processes in estuaries. This means that present models are limited in their ability to predict the dispersion of pollution and sediment. Remotely-sensed data offer more extensive spatial coverage. However, previous studies based on conventional optical, thermal and radar imaging sensors have failed to obtain sufficient temporal coverage in order to map the details of the current field. The new technique of along-track interferometry (ATI) is attractive because it can estimate the instantaneous surface flow from a single pass over a whole estuary. Here we present some observations over the Tay Estuary, Scotland, which illustrate the benefits of this technique. The results demonstrate the potential for enhancing existing hydrodynamic models of this region.
