The use of imaging systems to monitor shoreline dynamics [PDF]

, 2005
The development of imaging systems is nowadays established as one of the most powerful and reliable tools for monitoring beach morphodynamics. Two different techniques for shoreline detection are presented here and, in one case, applied to the study of ...

Flash Drought Assessment: Insights from a Selection of Mediterranean Islands, Greece

Hydrology
Flash droughts are a significant natural hazard, characterized by rapid onset and potential to cause substantial economic and environmental impacts. This study utilizes ERA5 soil moisture data to identify and define historical flash drought (FD) events ...

The Role of Waves, Shelf Slope, and Sediment Characteristics on the Development of Erosional Chenier Plains

Geophysical Research Letters, 2018
Cheniers are sandy ridges parallel to the coast separated by muddy deposits. Here we explore the development of erosional chenier plains, which form by winnowing during storms, through dimensional analysis and numerical results from the morphodynamic ...

A simple model for the formation of vegetated dunes

, 2000
A simple model for the dynamics of dunes associated with vegetation is proposed. Using the model, formation processes of transverse dunes, parabolic dunes and elongated parabolic dunes according to two environmental factors: i)the amount of sand at the ...

On modeling the variability of bedform dimensions [PDF]

, 2005
: Bedforms are irregular features that cannot easily be described by mean values. The variations in the geometric dimensions affect the bed roughness, and they are important in the modeling of vertical sorting and in modeling the thickness of cross ...

Expert opinion: uncertainties in hydraulic roughness [PDF]

, 2005
Water level predictions in rivers are used for a variety of purposes in water management. For example, designing flood defence measures and evaluating natural rehabilitation in flood plains, cannot be done without water level predictions.

Semicircular Coastal Defence Structures: Impact of Gap Spacing on Shoreline Dynamics during Storm Events

Journal of Marine Science and Engineering
Coastal erosion poses significant challenges to shoreline management, exacerbated by rising sea levels and changing climate patterns. This study investigates the influence of gap spacing between semicircular coastal defence structures on shoreline ...

MORPHODYNAMICS OF THE CHIRLEŞTI MUDFLOW (BUZĂU MOUNTAINS) [PDF]

Revue Roumaine de Géographie, 2012
The paper undertakes a morphological and morphodynamic assessment of a 1,350 m-long mudflow, followed up in various phases since its occurrence that poses a great danger to one of the main Trans-Carpathian roads in Romania.
