Purpose and Background
These presentations were recorded at the International Conference on Coastal Engineering 2026.
Analysis of Shoaling and Maintenance Dredging for Navigation Channel (16 minutes)
This presentation examines sediment shoaling processes and maintenance dredging challenges in major navigation channels. Participants will learn how sediment accumulation affects channel reliability, vessel operations, and dredging requirements. The speaker discusses methods used to analyze shoaling patterns, including dredging records, survey data, and predictive tools for future channel performance. Attendees will explore how deepening projects can influence future sedimentation rates and maintenance needs. The presentation evaluates alternative dredging strategies and advanced maintenance concepts to improve navigation efficiency while controlling costs. Lessons learned from channel management are presented through case studies from the Houston Ship Channel and related waterways. Participants will gain practical insight into long-term sediment management and navigation infrastructure planning.
Variability of Mangrove-Induced Resistance Coefficient on Wave Attenuation (18 minutes)
This presentation investigates how mangrove vegetation characteristics influence wave attenuation through variations in resistance coefficients. Participants will learn about the hydrodynamic processes involved when waves propagate through mangrove forests. The speaker evaluates drag and inertia coefficients associated with mangrove structures and examines how they affect wave energy dissipation. Attendees will explore the challenges of representing complex mangrove root systems within numerical models. The presentation compares laboratory observations with numerical simulations to better understand uncertainty in wave attenuation predictions. Results illustrate how vegetation geometry, water depth, and wave conditions can influence model performance. Participants will gain a deeper understanding of wave-vegetation interactions and coastal protection provided by mangrove ecosystems.
Corpus Christi Ship Channel Deepening and Lessons Learned from Beneficial Use Construction (10 minutes)
This presentation reviews the implementation of beneficial use projects associated with the Corpus Christi Ship Channel deepening program. Participants will learn about the engineering, construction, and adaptive management challenges encountered during large-scale sediment placement projects. The speaker discusses lessons learned from island creation, marsh development, and shoreline protection measures constructed using dredged material. Attendees will explore how unexpected geotechnical conditions, ship wake impacts, and design assumptions influenced project performance. The presentation highlights the importance of monitoring, flexibility, and field feedback during construction. Participants will gain insight into practical challenges associated with beneficial use implementation and coastal habitat creation. The session provides valuable lessons for future large-scale sediment management projects.
Experimental Investigation of the Effects of Boat Wakes and Wind Waves on Shoreline Erosion (11 minutes)
This presentation explores how boat wakes and wind-generated waves contribute to shoreline erosion through controlled laboratory experiments. Participants will learn about large-scale physical modeling techniques used to simulate wave-induced sediment transport. The speaker compares the erosive effects of recreational vessel wakes and naturally occurring wind waves under equivalent conditions. Attendees will examine how wave characteristics such as steepness and energy influence shoreline response. The presentation highlights differences in sediment transport patterns produced by boat-generated and wind-generated waves. Results provide insight into the relative importance of vessel traffic as a driver of shoreline change. Participants will gain a better understanding of erosion processes and how they can be incorporated into shoreline management strategies.
