  abstract = {{T}he morphology of sandy beaches is highly dynamic. {T}hey are influenced by the geology of the coastal area and external hydrodynamic forcing. {O}n long timescales (years to decades), it is more efficient and convenient to monitor beach evolution through remote sensing technics rather than through direct field measurements. {E}rosion is a major problem along the coastline of {G}hana with over 25 erosion hotspots, including {J}ames town. {H}ere, tides, {ECMWF} {E}ra{I}nterim re-analysis wave data and images covering the beach area have been obtained for the 2013-2014 period. {T}his paper presents preliminary results of the first efforts in processing video-derived observations of waves and shoreline change in {G}hana. {T}he pilot application shows a strong potential of the video system in providing fair quality wave data for beach management purposes where video wave characteristics are in good agreement with {E}ra{I}nterim global reanalysis (daily {RMSE} = 0.8 m and 0.7 m for {H}-b and {T}-p, respectively). {S}horelines extracted from video suggest large monthly variability driven by wave seasonality while shoreline change shows a subsequent erosion/accretion cycle.},
