Morphodynamics of a sandy beach during a one-year cycle at Sandbukt, Breivika, Troms, northern Norway
Six cross-shore beach profiles were monitored in a monthly interval at Sandbukt Beach at Breivikeidet, from October 2014 to October 2015, in order to study impact of storms on the beach profile and understand monthly, seasonal, and annual changes in the beach profile. Change in beach volume showed e...
