2. Work Content

A. Assemblage of comprehensive dynamical and sedimentary observational data sets
Starting point
Partners in this project have access to and will make readily available the following data sets for development of models both within this programme and (where required to) in other related European programmes.

North Sea scale
ZISCH . . . . . . . (Jürgen Sündermann to add)
NORTH SEA PROJECT. Fifteen months (1988-89) of moorings and monthly surveys (each 3000 km long and 100 stations), dynamics, SPM, nutrients, metals, chlorophyll and oxygen.

Coastal
HOLDERNESS. (Rapidly eroding glacial till coasts north of the Humber on UK east coast). Six months (1994-95) of moorings, monthly surveys, H.F. radar and air-borne remote sensing. Dynamics (unique inshore wave data set), SPM and bathymetric surveys.

Instrumentation deployed: in-situ current meters, wave buoys/pressure cells, ABS, OBS and transmissometers, meteorological buoys, air-borne CASI sensor, H.F. Radar, X-band radar, coast-surf zone monitoring, STABLE. (See Technical Annex 1.10 for further details)

NORTH FRISIAN Wadden Sea . . . . . . . (participants to add)

DUTCH COAST . . . . . . . (participants to add)

B. Existing dynamical pre-operational models
B1. Storm and tidal propagation models currently in use amongst the partners
Shelf/North Sea scale:

POL (Dr R. A. Flather)

IfM

Delft

MUMM

HYDROMOD

GKSS

B3. Turbulence Models

C. Rationalisation of existing models, development of interactions between models
POL, GKSS, K.U. Leuven, C.M., MUMM and Delft are all members of the WISE (Waves In Shallow Environments) group concerned with application of the above models in shallow water and the associated interactions.

The IfM has specialist experience in coupling current and turbulence models.

D. Sedimentation models
Random walk, Eulerian and semi-analytical sediment models have been developed by:

POL (J. P. McManus, 1994)

IfM

Delft

MUMM

E. Modelling
Simulations will be made extending over each of the three periods of the major observational exercises, namely:

1. Holderness UK, Oct 1994-Jan 1995
2. North Frisian Wadden Sea
3. Dutch Coast
4. Bilbao

Specifications for Operational Modelling
The degree of uncertainty produced in model output parameters as functions of uncertainty in model input parameters will be established, using variability from 6.2 as a basis for the ranges concerned.
