• Beach morphology is the surface shape of the beach.
• Eustatic sea level change is the global change to sea level
• Geology is the structure and arrangement of a rock
• Grading is the layering of sediments based on their size
• Integrated Coastal Zone Management (ICZM) are large sections of a coastline (sediment cells) which are managed with one integrated strategy. Management occurs between different political boundaries
• Impermeable is rock that does not allow rainwater to pass through
• Isostatic sea level change is a change in local coastline or land height relative to sea level
• Permeable is a rock that allows rainwater to pass through it
• Cost-benefit analysis is the evaluation of a coastal town's economic value, compared to the cost of the management required. Costs are tangible and intangible and can be economic or other costs such as visual impact
• Shoreline management plan (SMP) identifies all of the activities, both natural and human, which occur within the coastline area of each sediment cell and then recommends a combination of four actions for each stretch of that coastline: hold the line, advance the line, managed realignment and no active intervention
• Till is the deposits of angular rock fragments in a finer medium
