Clarity before a decision is made
The Littoral Processes and Shoreline Dynamics Model Module is an integrated modeling package designed to simulate non-cohesive sediment transport associated with waves and currents, littoral drift,…
This module uses a deterministic modeling approach. It allows multiple physical factors to be included as model variables, including processes that are often not represented in simplified semi-empirical formulas.

Decision Supported
Define when and how to use littoral processes and shoreline dynamics, including required data, configuration, validation, and scenarios.

Risk Controlled
Non-representative models, insufficient data, weak validation, and over-interpretation.

Success Criteria
Transparent, validated models that respond to scenarios at the decision scale.

Full technical basis and contextOpen this section to read the complete source technical narrative.
The Littoral Processes and Shoreline Dynamics Model Module is an integrated modeling package designed to simulate non-cohesive sediment transport associated with waves and currents, littoral drift, shoreline evolution, and beach profile formation.
This module uses a deterministic modeling approach. It allows multiple physical factors to be included as model variables, including processes that are often not represented in simplified semi-empirical formulas. For example, when an energy-flux approach is applied to complex coastal structures with different sediment particle-size distributions, model stability problems may occur and the simulation may fail. This module provides a more robust framework for handling such complex coastal conditions.
The module supports decision-making for environmental engineers, coastal managers, and coastal planners by improving the effectiveness of coastal design, restoration, and protection strategies.
This submodule solves diffusion equations over the intra-wave period to provide a detailed representation of non-cohesive sediment transport driven by waves, breaking waves, and currents.
Share the need, location, available data, and the decision to be supported.
The CORZ team will review the objective, scope, data availability, risk level, schedule, and required outputs to prepare a proportionate approach.
