intro story Coast / Estuary

Coast / Estuary

Coastal systems are among the most dynamic physical systems on earth and are subject to a large variety of forces. The morphodynamic changes occurring to coastlines worldwide are of great interest and importance. These changes occur as a result of the erosion of sediments, its subsequent transport as bed load or suspended load, and eventual deposition. 
Estuaries are partly enclosed water bodies that have an open connection to the coast. Estuaries generally have one or more branching channels, intertidal mudflats and/or salt marshes. Intertidal areas are of high ecological importance and trap sediments (sands, silts, clays and organic matter).
Within the Delft3D modelling package a large variation of coastal and estuarine physical and chemical processes can be simulated. These include waves, tidal propagation, wind- or wave-induced water level setup, flow induced by salinity or temperature gradients, sand and mud transport, water quality and changing bathymetry (morphology). Delft3D can also be used operationally e.g. storm, surge and algal bloom forecasting.

Coupling multiple TPAR files / Boundaries

Hello Delft3D Community,
Im working with  Flow (for sediment transport) coupled with wave. Till now i have used the TPAR.bnd file to change the wave direction by only using one boundarie orientation (South).
Now im trying to set up a model with changing boundariers from first orientation South to orientation North.  I created two TPAR files ( TPAR01.bnd for South and TPAR02.bnd for North) files attached to the boundaries.
When running the simulation there will be no waves simulated.
I put you the TPAR and Wave Print - Screenshot in the attachments.
It would be nice if somone has experience with this kind of problem and give me a hint.
