Description :
This paper assesses the contribution of 2 system variables (secondary airflow patterns and fetch distance) to medium-term (months to years) dune development. Three methods were employed. First, sand drift potentials were calculated using 2 years of regional wind data (site Magillan Strand, Northern Ireland) and a sediment transport model. Second, wind data and large trench traps were used to assess the actual sediment transport patterns over a two-month period. Third, a remote-sensing technique was utilized to gauge, qualitatively, sediment transport patterns over a one-month period.
