Description :
The Fryberger model uses standardized wind data to estimate regional aeolian sediment drift potential (DP), which allows for interpretation and classification of aeolian dune landscapes. This paper identifies systematic frequency and magnitude biases in the model that result from : variations in wind direction sector range, and use of wind speed class mid-point values over more statistically representative values. The significance of these biases is tested using unclassified data from Stanhope, Prince Edward Island, Canada.
