Coastal Engineering Special Issue on CoastView Coastal Engineering Special Issue on CoastView
ObjectiveObjective
The main aim is to illustrate The main aim is to illustrate howhow video-derived CSIs can be video-derived CSIs can be used to help coastal managers for better beach planning used to help coastal managers for better beach planning /exploitation /management for recreational purposes./exploitation /management for recreational purposes.
When the When the beach is used for recreational purposes, the beach is used for recreational purposes, the beach (and the manager) has to provide (and to manage):beach (and the manager) has to provide (and to manage):
• resourcesresources (beach surface, environmental quality,...) (beach surface, environmental quality,...)
• servicesservices (accesses, showers, ...) (accesses, showers, ...)
• safsafetyety (hazardous conditions, lifeguard services,..) (hazardous conditions, lifeguard services,..)
