On the role of biomass on coastal morphodynamics in natural and urban Mediterranean beaches
… and natural forcings. The evolution of the geomorphological setting of the urban coastal belt of Cagliari was also carried out through a sea-land approach and a multidisciplinary and multi-temporal investigation summarized in a geomorphological map. Furthermore, the results of the water …

HIDDEN IN THE COAT: GEOMICROBIOLOGICAL INVESTIGATIONS OF ROCK ART ECOSYSTEMS AND CHALLENGES FOR THEIR SUSTAINABLE PRESERVATION
… a complicated issue that needs expertise in both geology and biology, therefore we combined interdisciplinary methods in geochemistry, molecular biology and bioinformatics to further understand how microbial communities are involved in the formation of rock art coatings. In the last part of this …

Bio-physical controls on tidal network geomorphology
… insights into the bio-physical controls on the geomorphology of tidal networks. To this end, a combination of remote sensing, modelling and field activities was employed. A geo-spatial analysis was performed at Queen Mary, University of London (UK), to address the variability of tidal network …

Global development, acoustic and emissive consequences of hydropower
… for decades. However, the lack of coordinated, georeferenced databases has hindered catchment decision making, and limited the development of regional and global research in particular. In Chapter 1, the primary objectives were to create a high resolution, georeferenced database of hydropower …

Controls on and Morphodynamic Effects of Width Variations in Bed-load Dominated Alluvial Channels: Experimental and Numerical Study
… erosion and accretion of banks, within various geomorphic, environmental and anthropogenic contexts, which set the most relevant factors controlling the morphological dynamics of the river corridor. In turn, changes in channel width imply alterations of the river channel morphodynamics at a …

Classifying Single-thread Rivers: A European perspective
… involves subdividing rivers along a continuum of geomorphological characteristics to assign river reaches to geomorphologically-meaningful classes according to their channel dimensions and forms, and floodplain characteristics. The classification was developed and tested through three research …

Morphodynamics and driftwood dispersal in braided rivers
… dynamics. In-channel large wood has a relevant geomorphic and ecological role as it enhances morphological diversity and creates a variety of physical habitats that sustain high biodiversity. Its presence can also increase flood risk and therefore wood is often removed from streams especially in …

Meandering rivers morphodynamics - integrating nonlinear modeling and remote sensing
… is nowadays employed in a wide range fields in geophysics; for this reason, the past years have seen the prolific development of numerous algorithms for remote sensing analysis. However, remote sensing of meandering river morphodynamics has not been consistently integrated with morphodynamic …

River temperature behaviour in changing environments: trends, patterns at different spatial and temporal scales and role as a stressor
… quality parameters as it controls several key iogeochemical, physical and ecological processes and river ecosystem functioning. Thermal regimes of several rivers have been substantially altered by climate change and other anthropogenic impacts resulting in deleterious impacts on river health. …
