  abstract = {{T}he first large nearshore field experiment in the {G}ulf of {G}uinea was conducted at {G}rand {P}opo {B}each, {B}enin, in {F}ebruary 2013, on an open wave-dominated micro- to meso-tidal coast, located mid-way between {C}otonou and {L}ome harbours. {T}he overall project aims at understanding at multi-scale (from event to interannual) the causes of the dramatic erosion observed throughout the {B}ight of {B}enin, and caused by the interaction of a large littoral drift with human engineering works. {G}rand {P}opo 2013 experiment was designed to measure the processes over the short term and to test the ability of an installed video system to monitor the evolution of this stretch of coast over the longer tenn. {T}he beach, characterized by a low-tide terrace and a high tide reflective part, experiences a long swell ({H}s=1.6 m, {T}p=16 s, oblique incidence similar to 15-20 degrees). {T}opographic surveys showed a double beach cusp system interaction and repeated surf-zone drifter runs revealed high flash and swash rip activity driven by wave dissipation over the terrace and energetic swash dynamics at the upper reflective beach. {S}wash was measured over a cusp system at two locations using video poles. {W}ave reanalyses ({ERAI}nterim) were used to determine the wave climate and its variability, and to quantify sediment transport. {T}his robust methodology is thought to be replicated elsewhere in different coastal environments in {W}est {A}frica, in particular with the objective to monitor various sites within the framework of the new {W}est {A}frican {C}oastal {O}bservatory.},
