  abstract = {{I}n this study, we explore the potential of a nearshore video system to obtain a long-term estimation of coastal variables (shoreline, beach slope, sea level elevation and wave forcing) at {G}rand {P}opo beach, {B}enin, {W}est {A}frica, from {M}arch 2013 to {F}ebruary 2015. {W}e first present a validation of the video system with field data over a 10-day experiment conducted on {G}rand {P}opo beach in 2014. {S}econdly, 2-years daily and monthly timeseries are extracted and their variability is described as a function of regional forcing and climatic modes. {A}ll variables show large monthly variability. {T}he longshore sediment transport estimated locally from video is in agreement with that derived from {E}ra-{I}nterim wave data re-analyses. {R}esults show that the shoreline responds predominantly to tides at the event scale and to waves. {O}verall, this study suggests that video stations are efficient tools to monitor coastal processes over the long term, in complement with other conventional approaches. {A}lthough no clear conclusions can be drawn on inter-annual variability, the results show that it is important to build up extended coastal observation networks to address coastline changes over a wide range of scales.},
