Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Model type Modular Model part of larger framework Note on status model Date note status model Spatial dimensions Spatial extent Model domain One-line model description Aggregate scale morphodynamic model of integrated coastal systems Extended model description A length-, and time-averaged representation of coastal system elements including the inner shelf, shoreface, surfzone, inlet, inlet shoals, and estuary channels and tidal flats. The multi-line nature of the morphodynamic model allows it to represent large-scale sediment transport processes with a combination time-average physics empirical relationships. A major use is to represent the interactions between system components to develop with changes in large scale forcing such as accelerated sea level rise, changes in river sediment input (ie. dams), changes in estuary tide prisms (ie. dikes) and the like.

Time histories of the inlet cross-section and the areas of bar, channels and tidal flats in the estuary Output format ASCII Other output format Pre-processing software needed? No Describe pre-processing software Post-processing software needed? No Describe post-processing software Visualization software needed? No If above answer is yes Other visualization software Describe processes represented by the model Time- and length-averaged sediment transport in shelf, shoreface and surf zone environments combined with morphodynamic-driven sediment flux through inlet, along ebb tide delta and with the bay or estuar. Describe key physical parameters and equations These are described in the extensive comments within the fortran program. Describe length scale and resolution constraints Typical applications involve coastal systems tens to hundreds of kilometers in extent. Very useful when there are many components in the coastal system. Although the gridded portion of the model usually use delta x and y values on the order of 100s of meters there is a sub-grid scale representation of the shoreline position with resolution of meters. Describe time scale and resolution constraints Averaging time is on the order of annual averages so that individual storm events are not represented. Problems usually are scaled for years, to decades all the way up to millenia. Describe any numerical limitations and issues Probably more than we know but none come to mind. Describe available calibration data sets Like most morphodynamical models the user is to supply long-term coastal change data from measured data. Upload calibration data sets if available: Describe available test data sets Several papers have been published that can be used in comparison tests (simply Google Niedoroda) Upload test data sets if available: Describe ideal data for testing User supplied time history of shoreline and depth changes over time with supporting long records of short-term wave and current measurements. Do you have current or future plans for collaborating with other researchers? This model continues to evolve. The users are encouraged to replace subroutine with very simplified representations of physics (eg. wave refraction and shoaling) with superior codes. They are requested to pass these back to the authors for inclusion in the new version. Similar requests are made of those using the model for interesting teaching situations. This model will form a basis of the SL-PR model now funded for development and use with coastal response to sea level rise problems. Is there a manual available? No Upload manual if available: Model website if any Model forum / discussion board Comments This model is actively under development as of the spring of 2009.
