The state of the lower Volta Delta Beaches in Ghana from field observations.

The continuous collection of data is important, particularly for developing models for local applications. It is also important to collect in situ data in this observation scarce region to improve our understanding of coastal evolution. The data presented here were planned and collected along a 90 km coastline. The experiment holds significant scientific value as it marks the first comprehensive data-gathering effort along the Volta Delta within the Bight of Benin, West Africa. Several projects, decision-makers, and scientists will make use of this data to calibrate their models. The study was executed in 2023, and it provides a comprehensive description of the morphodynamical characteristics of the study area and identifies the factors influencing the changes. The data include nearshore and riverine bathymetry, topography, sediment grain size distribution, and waves in the study area. The research experiment provides a foundation for future extensive and long-term investigations along the LVD and promotes localized investigations.
