Estuary schematisation in behaviour-oriented modelling

Estuary schematisation in behaviour-oriented modelling
Estuary schematisation in behaviour-oriented modelling
ASMITA (Aggregated Scale Morphological Interaction between Tidal basin and the Adjacent coast) is a
behaviour-oriented modelling approach which represents estuarine systems schematically. It was originally
developed for ‘classic’ tidal inlets such as those found in the Dutch Wadden Sea and Venice lagoons, where
schematisations of two or three interacting elements (e.g. flat, channel and possibly an ebb-tidal delta) are
appropriate. However, estuaries show a much wider range of form and human interference than these cases.
This paper presents results for two UK estuaries with differing morphologies and management histories. The
Ribble Estuary and Southampton Water are poorly represented by standard two and three element
schematisations, and required novel schematisations which considered the dominant processes shaping the
two estuaries. The new schematisations gave model predictions that (1) are better than the baseline
assumption of no change through time, (2) are better than standard schematisations and (3) are physically
reasonably whilst retaining simplicity. These results demonstrate a possible generic methodology to test
different schematisations using simple models to characterise estuarine morphodynamics as a preliminary
stage of estuary assessment.

Abstract

ASMITA (Aggregated Scale Morphological Interaction between Tidal basin and the Adjacent coast) is a
behaviour-oriented modelling approach which represents estuarine systems schematically. It was originally
developed for ‘classic’ tidal inlets such as those found in the Dutch Wadden Sea and Venice lagoons, where
schematisations of two or three interacting elements (e.g. flat, channel and possibly an ebb-tidal delta) are
appropriate. However, estuaries show a much wider range of form and human interference than these cases.
This paper presents results for two UK estuaries with differing morphologies and management histories. The
Ribble Estuary and Southampton Water are poorly represented by standard two and three element
schematisations, and required novel schematisations which considered the dominant processes shaping the
two estuaries. The new schematisations gave model predictions that (1) are better than the baseline
assumption of no change through time, (2) are better than standard schematisations and (3) are physically
reasonably whilst retaining simplicity. These results demonstrate a possible generic methodology to test
different schematisations using simple models to characterise estuarine morphodynamics as a preliminary
stage of estuary assessment.
