Coastal Soil Stabilization and Erosion Control

Course Description:

This course presents a comprehensive, forensic-level framework for analyzing, designing, constructing, and managing coastal soil stabilization systems across a wide range of environments—from estuarine marsh shorelines to open-ocean barrier islands. The curriculum progresses logically from fundamental coastal processes through advanced stability modeling and AI-assisted predictive management.

Learning Objectives:
 

Upon completion of this course, the participant will be able to:

1. Analyze coastal hydrodynamic processes including wave transformation, storm surge, wave setup, tidal fluctuation, and longshore sediment transport, and explain how these processes drive erosion and soil instability.
2. Evaluate coastal erosion mechanisms such as toe scour, rapid drawdown, cyclic pore pressure buildup, bluff retreat, dune scarping, and sediment budget imbalance.
3. Develop comprehensive geotechnical investigation programs for coastal environments, incorporating marine drilling methods, CPTu interpretation, cyclic strength evaluation, hydrogeologic assessment, and subsurface modeling.
4. Assess liquefaction potential and cyclic degradation risks in saturated coastal sands and soft clays subjected to wave and storm loading.
5. Design hard stabilization systems including revetments, seawalls, bulkheads, and sheet pile walls using appropriate hydraulic loading criteria, embedment depth calculations, filter compatibility requirements, and corrosion allowances.
6. Perform global stability and seepage analyses under static, transient, and rapid drawdown conditions using limit equilibrium and numerical modeling approaches.
7. Design and evaluate geosynthetics in marine applications, including filtration, separation, reinforcement, geotextile tube containment, and durability under UV, abrasion, and saline exposure.
8. Apply ground improvement techniques such as deep soil mixing, jet grouting, and densification to enhance bearing capacity, reduce settlement, and improve coastal slope stability.
9. Engineer nature-based and hybrid stabilization systems by quantifying wave attenuation, vegetation reinforcement effects, sediment accretion potential, and foundation settlement impacts.
10. Assess construction-stage risks and quality control requirements for marine installation of stabilization systems, including embedment verification, anchor testing, drainage installation, and geosynthetic survivability.
11. Design and implement monitoring programs incorporating instrumentation, bathymetric surveys, shoreline mapping, and time-series performance analysis.
12. Interpret post-storm forensic evidence to diagnose failure mechanisms and recommend technically sound remedial measures.
13. Integrate sea level rise projections and climate variability into long-term shoreline stabilization and resilience planning.
14. Apply AI-assisted predictive modeling tools to forecast shoreline retreat, identify erosion hotspots, detect anomalous structural behavior, and optimize phased stabilization investments while maintaining engineering oversight.
15. Develop adaptive management strategies that translate monitoring data into targeted maintenance and reinforcement actions to extend system service life.
