In order to reduce coastal erosion, beach nourishment plays an important role in coastal protection around the world. Many countries spend a lot of money in relation to these activities in spite of economical, social and environmental consequences. Despite existing researches on nourishment efficiency, there are some technical aspects that have not been still researched. With the aim of studying the sand volume variation after beach nourishment works, a fast and novel application has been described herein in order to measure sand beach density in-situ through a nuclear densimeter. In the same way, grain size analysis and topographic levelling have been performed at different beaches in the province of Cadiz (SW of Spain). After the nourishment activities, significant differences of levelling have been registered due in part to density and porosity sand variations. From a technical and economical point of view, the applicability of the methods and results published in this paper can be very useful to estimate an accurate sand volume for other similar beach nourishment projects.
