Abstract The arid coasts of North Africa, extending over 4633 km from the Gulf Tunis to Nile Delta, are undergoing pronounced shoreline retreats and coastal floodings that reported as a consequence ongoing sea level rise resulting global warming. Of particular interest abnormal dynamics for deltaic sandy beaches, which severely impacted by abrupt decadal variabilities in both climatic anthropogenic drivers their increased vulnerability disturbances hazards. Unfortunately, evolution,...
Abstract The low‐lying, arid coastal regions of the Southern Mediterranean Basin, extending over 4,600 km, face daunting sea level rise and hydroclimatic changes due to shifting weather patterns. impact these factors on urban buildings infrastructure must be better understood. Alexandria, a historic densely populated port city in Egypt representative several towns Mediterranean, has experienced 280 building collapses along its shorelines past two decades, root causes are still under...
Shoreline retreat along extended semi-arid areas of North African coasts are indicative the imbalance coastal sedimentary processes due to modern abrupt changes in precipitation patterns and urban growth. Monitoring diachronic shoreline position land-use from 1952 2018 coast Hammamet Bay central-east Tunisia, using both aerial orbital photogrammetric scenes Digital Analysis System 1887 2018, suggests rates ranging −1.3 −5.6 m/yr. Such abnormal when compared average −0.07 m/yr suggested by...
Abstract Sandy beaches in Southern California are experiencing rising coastal erosion due to changes precipitation patterns and urban growth. As a result, beach nourishment is necessary for mitigation. In our study, we forecast the rates of shoreline retreat required volumes sand mitigate it coming decades. We employ photogrammetric multi-decadal positioning Digital Shoreline Analysis System methods measure predict evolution Gulf Santa Catalina California. This region hypothesized be...
The Flow Regimes from International Experimental and Network Data (FRIEND-Water) is the oldest UNESCO Flagship Initiative within Intergovernmental Hydrological Programme (IHP).  Active since 1985, it seeks to facilitate, promote foster collaborations across borders between scientists (hydrologists related disciplines) conduct studies on shared river basins. programme has evolved over time focus four key themes relating (i) data collection sharing, (ii) impacts of global change...
Port areas, located at the land-sea interface, are crucial coastal socio-ecosystems exposed to local pollution and terrigenous inputs from watersheds. Silting sedimentation in ports pose complex management challenges. It is essential understand port environments, which requires regular monitoring of water sediment quality. In-depth knowledge, especially under varying hydroclimatic conditions, helps better manage effects dredging operations, including potential reuse sediments based on their...
In the context of rapid increase climate change stressors, Mediterranean coastal areas are threatened by declining biodiversity and degradation natural landscapes. The IPCC 2014 report identified Sea as a hot spot region from human-driven global warming estimated to +2°C for 2050. However, heatwave’s frequencies Surface Temperatures (SST) during last summer reveals that this situation is underestimated with SST 2024 anomaly record +5.9°C (Copernicus Marine).

The aim of this study is the reconstitution recent morpho-sedimentary evolution Medjerda River delta. We examine spatio-temporal shoreline between 1936 and 2016 using satellite images, complemented by sedimentological geochemical analyses 210Pbex 137Cs radiometric data. general tendency shows an increasing progradation (300 ± 12 m) 2016. Yet mesoscale Net Shoreline Movement position (NSM) End Point Rate (EPR) reveal erosion pattern estimated to be −20 m 0.15 m/yr during period 1988–1999....
Abstract. Recent sedimentary and morphological changes at the new mouth of Medjerda-River (Gulf Tunis) are investigated using a multiproxy approach sediment cores complited by 210Pbex 137Cs method dating. The subject study is to focus on surveying evolution Medjerda-Raoued Delta caused human intervention in management main tributaries (artificial channel Henchir Tobias). Sediment (CEM-1 CEM-3) were subjected both approaches (Grain size, geochemical analysis dating radiometric 137Cs)....
Abstract. Due to pronounced hydroclimatic fluctuations and rapid urban growth, coastal lagoonal systems in the Southern Mediterranean semi-arid areas undergo shoreline retreats increased floodings. The socioeconomic impacts of these alarming changes remain poorly uncharacterized. To address this deficiency, we calculate Socioeconomic Vulnerability Index (SVI) based on decadal retreat land use occupation considering study case lagoon Ghar El Melh Tunisia which is representative several...
The low-lying, arid coastal regions of the Southern Mediterranean basin, extending over 4600 km, face daunting sea level rise and hydroclimatic changes due to shifting weather patterns. impacts above on urban buildings infrastructure still need be more qualified understood. Alexandria, a historic densely populated port city representative several cities in Mediterranean, has experienced 280 building collapses near its shorelines past two decades, with root causes being investigated. We...
Abstract. The aim of this study consists in testing the effectiveness satellite data order to monitoring shoreline and sedimentary features changes, especially rapidly changing Gulf Tunis coast. area is located western bay (Southern Mediterranean Sea) which characterized by sandy beaches Ghar Melah Raoued (Medjerda Delta area). aerial photographs imageries were used for mapping evolution shoreline. Diachronic (satellite imagery, photography topographic maps) monitor quantify, coastal areas....
Abstract. The sedimentary contributions of the Medjerda to coastal zone are poorly measured, and there is no chronicle observations. In this context, sediment monitoring appears indispensable for quantification transport at outlet. This study focuses on largest watershed in Tunisia, Wadi (23 600 km2). main objective work assess reduction following anthropogenic intensification basin, especially since construction many large dams. order collect information actual deposits over several years,...
Abstract. The FRIEND-Water program (FWP) is the oldest and most transverse (i.e. Flagship Initiative) within Hydrological Intergovernmental Program (IHP) from UNESCO. FRIEND means “Flow Regimes International Experimental Network Data”. FWP dedicated to allow large communities of hydrologists associated disciplines collaborate across borders on common shared data scientific topics which are addressed through world regions. has evolved in its 35 years existence. There 8 regions gather tenths...
