Beaches attract people (leisure, recreation and sport activities) and are business entities for the tourism industry.
Beaches possess elements of hazard for human beings and for the tourism industry.
Via scientific ergonomics approach we are studying the beach and surf as the workspace of lifeguards and trying to optimize its functions.
Ergonomics (or human factors ) is the application of scientific information concerning humans to the design of objects, systems and environment for human use and study human capabilities in relationship to their work demands.
The scientific results are to be integrated into a Beach Safety Management (BSM) system (as part of CZM).
Illuminance is the total luminous flux incident on a surface, per unit area. It is a measure of the intensity of the incident light, … to correlate with human brightness perception.
Luminance is a photometric measure of the density of luminous intensity in a given direction. It describes the amount of light … or is emitted from a particular area, and falls within a given solid angle.
Reflectance is defined as the ratio of incident luminous flux on a sample surface to reflected flux from the surface.
Contrast is the difference in visual properties that makes an object distinguishable from other objects and the background. In visual perception of the real world, contrast is determined by the difference in the color and brightness of the object and other objects within the same field of view.
Industrial engineering tools such as Ergonomics are crucial for modern Beach Water Safety Management which plays an important role in modern tourism industry.
Parameterization of lifeguard's, swimmer's and environmental morphodynamic factors and modelling of the results can illuminate the working-space: the beach, and make the whole work "drowning prevention and lifesaving" more efficient .
Implying professional Industrial Engineering tools and methodologies can save many lives and be cost effective .
