Regular monitoring of coastal areas is a prerequisite to evade any imminent erosive disaster. However, data-driven decisions become more uncertain when platform unable capture events certain frequency. Erosion along Ghana's coastline endemic as in most the Gulf Guinea countries West Africa. The current challenge how document and understand dimensions erosion despite limited human logistical capacity. In present study, shoreline change was assessed by an intensive multi-platform data...
The fiscal and social cost of ameliorating the impact coastal erosion resulting from climate change is an increasing burden for states, in developing nations physical interventions implemented may present a double agony - debt levels potentially obstructing livelihoods rural coasts. Against this background, study was conducted to explore hard-engineered protection on vulnerability community Ghana using combination Unmanned Aerial Vehicles (UAV), geographic information system tools survey....
Abstract There is a relative lack of research, targeted models and tools to manage beaches in estuaries bays (BEBs). Many have been highly modified urbanised, for example port developments coastal revetments. This paper outlines the complications opportunities conserving managing BEBs estuaries. To do this, we focus on eight diverse case studies from North South America, Asia, Europe, Africa Australia combined with broader global literature. Our key findings are as follows: (1) exist under...
Abstract Estuarine shorelines similar to marine coastlines are highly dynamic and may increase disaster risk in vulnerable communities. The situation is expected worsen with climate change impacts increasing anthropogenic activities such as upstream water management. This study assessed shoreline changing trends along the Volta river estuary Ghana well coastline using satellite imageries, orthophotos topographic maps spanning a period of 120 years (1895, 1990, 2000, 2005 2015). Linear...
In a context of global warming characterized by mean sea level rise and extreme meteorological events, the study causes for coastal flooding is essential to protect communities ecosystems. Densely urbanized, rather unprotected cities in developing countries such as historic Saint Louis city Senegal are particularly vulnerable hazards. From satellite-derived high resolution DEM ocean reanalyses, here we quantify water order identify neighborhoods places particular socio-economical interest...
Certain communities along the coast of Ketu South Municipality in south-eastern Ghana, remain vulnerable to coastal flood events from storm surges, high tidal waves, lagoon overflow, and heavy rainfall. However, local conditions that make these are poorly understood knowledge on which most is lacking. This study improves conceptual understanding different dimensions vulnerability exist across various levels each exposed community exhibits. The surveyed 354 household heads selected...
Like low-lying sandy coasts around the world, Ghanaian coast is experiencing increasingly frequent coastal flooding due to climate change, putting important socioeconomic infrastructure and people at risk. Our study assesses major factors contributing extreme water levels (ECWLs) from 1994 2015. ECWLs are categorized into low, moderate, severe corresponding 30th, 60th, 98th percentiles, respectively. Using these three over Pleiades satellite-derived digital elevation model topography,...
In today's context of rising sea levels and subsiding land topography, coastal flooding is a major concern for areas, both nationally, regionally, internationally. A detailed understanding these two phenomena prerequisite effective flood management. The main objective the present study to contribute impact subsidence sea-level rise on in Saint-Louis, particular Langue de Barbarie, by producing vulnerability map submerged surfaces. To this end, Synthetic Aperture Radar (SAR)...
Coastal erosion has become an issue globally. As the sea level continues to rise due global warming, projections are that would increase. To address sustainably, relevant scientific information such as sediment transport and shoreline dynamics is required at local scales. Over years, eastern coast of Ghana been mainly evaluated using low-resolution imagery challenges in retrieving high-resolution data nearshore region. An unmanned aerial vehicle (UAV) approach was used assess beach evolution...
Field measurements of longshore sediment transport have been performed in the surf zone along Denu Beach, located Volta Region Ghana, West Africa. This study consisted measuring rates by deployment modified versions Kraus streamer traps on a cross-shore distance, which was about half average width. In addition to measured rates, data waves, currents, and other morphological parameters were collected with simple low-cost instrumentation. total, 22 datasets obtained through several days...

<title>Abstract</title> Field observations along West Africa are of extreme importance for understanding rapid beach geomorphological changes. Here, we conducted comprehensive field surveys to understand the and hydrodynamic conditions Ghana's lower Volta Delta. Over five months, in situ data were collected 90 km coast, examining temporal bathymetry, profiles, width variations, waves, grain sizes. The primary objective was determine factors behind significant coastal erosion flooding,...
Erosion is a major global challenge facing coastal regions, and it projected to increase on regional scale as sea levels continue rise. Deltas, which are important ecosystems, particularly vulnerable due their low-lying nature, subsidence, reduction in sediment supply, population increase, exposure an increasing frequency of extreme events. The need for sustainable management these systems requires accurate estimates shoreline dynamics at the local higher spatial resolutions engineering...
The Volta delta(Ghana, West Africa) is increasingly impacted by sea level rise (SLR). SLR makes the delta mostly vulnerable to flooding, salinization of water resources and agriculture fields, permanent loss lands. This would potentially threaten present a growing risk its population, infrastructure economy, even worsen due land subsidence (LS). Relative (RSLR) in this study rate LS with respect SLR. It thus very important precisely quantify rates together as well planning assessment...
Although vulnerability assessments have been widely conducted along the coast of Ghana, they not focused on factors contributing to social households and communities disaster risks. Using an indicator-based approach, this study examines that affect exposure, susceptibility adaptive capacity in Volta estuary, Ghana. Results indicate all within area were exposed climate change related hazards. However, two communities, Azizanya Ada East District Fuveme Anloga District, highly with unweighted...
The study leverages Bayesian ontology to model consequences, uncertainty and expert judgment in quantifying risk with shoreline change at the Volta Delta. explores integration of networks opinions comprehensively assess address erosion threats, thereby contributing sustainable development environmental resilience. Modelling involves analysing variables, including potential occurrences, estimated likelihoods, judgments. creates a thorough appraisal structure for different erosion-related...
