Abstract: The Littoral Environment Observation (LEO) program uses volunteer observers recruited to obtain daily visual observations of such coastal variables as breaker height, wave period, direction of wave approach, wind speed and direction, longshore current velocity, and beach slope. Observers obtain the data using simple, inexpensive equipment and in some cases, like wave height and direction, are asked to simply record a visual estimate. The LEO program has been ongoing since 1968 and observations have been made at over 200 sites along the coasts of the United States. The information collected has been placed in a computer data base and is available to the coastal community. Refs.
