Assessing beach width dynamics through earth observations

Coasts are constantly under the pressure of hydrodynamic conditions such as waves, tides, and storms. In the Netherlands, sand nourishments are executed every few years in order to maintain the country’s sandy beaches for purposes of safety, recreation, and ecology. In order to determine where to carry out these nourishments, the whole sandy...

Satellite image processing for the coarse-scale investigation of sandy coastal areas

In recent years, satellite imagery has shown its potential to support the sustainable management of land, water, and natural resources. In particular, it can provide key information about the properties and behavior of sandy beaches and the surrounding vegetation, improving the ecomor-phological understanding and modeling of coastal dynamics....

Deriving Beach Grain Size from Satellite Imagery: A multimethod approach for deriving intertidal beach slopes and sediment grain sizes for different coastal environments

The world's coasts are at risk: an estimated 24% of the world's beaches are eroding. Extreme events such as storms continuously threaten the coastal region and pose a serious risk of coastal flooding. Under the influence of climate change, the seaward pressures are only expected to increase. Sea level rise is accelerating, storm intensities and...

Multi-case Evaluation of Empirical Methods for Satellite-Derived Bathymetry

Research on the physical, ecological and environmental processes in the coastal zone often rely on the availability of accurate bathymetric information. The traditional method to acquire these data is by conducting depth soundings from a vessel, which is a very accurate way for measuring bottom elevations in all kinds of water, but has as a...

Coastline evolution around African seaports: An evidence database from space

Seaports are important maritime commercial facilities and key hubs for national and global trades. There is a growing need for seaborne transport and, hence, seaport facilities, especially in emerging economies due to economic and population growth, such as in Africa. In sedimentary environments, port construction may induce coastal impacts...

The physical processes influencing morphodynamics in braided rivers: A case study on the Ayeyarwady River

The Ayeyarwady River is a river with large hydrological variations and an abundance of relatively fine non-cohesive sediment, causing the dynamic behaviour of the river with fast shifting channels. This dynamic behaviour, together with the large hydrological variations, is the source of a frequently flooding river with a moderate navigability....
