The ongoing rise in sea level affects tidal propagation and circulation estuaries, these changes can have far reaching consequences on the sediment dynamics, water quality extreme levels. This study aims at anticipating evolution of dynamics Tagus (Portugal) 21st century, particular due to (SLR). existence a resonance mode about 8 hours this estuary, that selectively amplifies both semi-diurnal quarter-diurnal constituents, makes response estuary SLR unique. was conducted with shallow model,...
Abstract The Anthropocene has been proposed as a profound, globally synchronous rupture in the history of Earth System with its current state fundamentally different to that Holocene and driven by geological force human activity. Here, we show how stratigraphy is being made lake heavily impacted upon climate change activities. For one largest inner-Alpine catchments European Alps, draw attention sedimentation rates are product non-stationary, reflexive, actions. In Lake Geneva, identify both...
Abstract Recent climatic warming and associated glacial retreat may have a large impact on sediment release transfer in Alpine river basins. Concurrently, the transport capacity of many European streams is affected by hydropower exploitation, notably where flow abstracted but supply downstream maintained. Here, we investigate combined effects climate change abstraction morphodynamics Borgne River, Switzerland. From photogrammetrically derived historical Digital Elevation Models (DEMs), find...
Abstract Deltas are important coastal sediment accumulation zones in both marine and lacustrine settings. However, currents derived from tides, waves or rivers can transfer that into distal, deep environments, connecting terrestrial depozones. The system of the Rhone River Lake Geneva is composed a sublacustrine delta, deeply incised canyon distal lobe, which resembles, at smaller scale, deep‐sea fan systems fed by high discharge rivers. From comparison two bathymetric datasets, collected...
Abstract. Suspended sediment export from large Alpine catchments (> 1000 km2) over decadal timescales is sensitive to a number of factors, including long–term variations in climate, the activation–deactivation different sources (proglacial areas, hillslopes, etc.), transport through river system, and potential anthropogenic impacts on flux (e.g. impoundments flow regulation). Here, we report marked increase suspended concentrations observed close outlet upper Rhône River Basin mid–1980s....
Silva, T.A., Freitas, M.C., Andrade, C., Taborda, R., Freire, P., Schmidt, S., Antunes, 2013. Geomorphological response of the salt-marshes in Tagus estuary to sea level rise.Salt-marshes are highly valuable ecosystems due their role supporting aquatic and bird life. Furthermore, many anthropogenic activities such as agriculture, salt production or aquaculture targets these areas. They also act protective barriers shores, given ability dissipate most wave current energy high tide. Sea rise...
Salt marshes are highly valued coastal environments for different services: coastline protection, biodiversity, and blue carbon. They vulnerable to climate changes, particularly sea-level rise. For this reason, it is essential project the evolution of marsh areas until end century. This work presents a reduced complexity model quantify salt marshes’ in rise (SLR) context through combining field remote sensing data: SMRM (Simplified Marsh Response Model). two-dimensional rule-based that...
