- Abstract:
- ... Around 0 AD, the Rhine-Meuse estuary in the southwest of the Netherlands was a typical coastal plain estuary. Drainage of peatland and land subsidence behind the dunes later caused the sea to penetrate into the land. Most of the peat was eroded, and by 1000 AD the so-called Delta area had turned into a landscape of large estuaries and intertidal zones. Rotterdam developed from a small fishing vill ...

- Abstract:
- ... River incision into bedrock drives the topographic evolution of mountainous terrain and may link climate, tectonics, and topography over geologic time scales. Despite its importance, the mechanics of bedrock erosion are not well understood because channel form, river hydraulics, sediment transport, and erosion mechanics coevolve over relatively long time scales that prevent direct observations, an ...

- Abstract:
- ... Biodiversity loss is a global problem with freshwater bivalves considered among the most endangered biota. The freshwater pearl mussel, Margaritifera margaritifera, is declining throughout its range owing to habitat degradation and overexploitation. In most of its range, populations are regarded as reproductively non‐functional, which has led to the development of captive breeding programmes. A no ...

- Abstract:
- ... Solidification is a very effective way to alleviate heavy metal impacts to the environment. In this paper, an improved method was adopted herein for the solidification/stabilization (S/S) of sediments with cement-based additives and low content of cement in S/S materials. Sediments in Xiangjiang River, containing high concentrations of Cu, Cd, and Pb, were solidified/stabilized by binders of cemen ...

- Abstract:
- ... Since the Neolithic, humans have gathered along coastal plains, where they had to face sea level rise and subsidence without the technology to oppose these processes. When sea level stabilized, approx. 6.000 yr. B.P., coastal colonization was allowed, but where mountain deforestation was carried out river sediment input increased tremendously: settlements were disconnected from the shore and harbo ...

- Abstract:
- ... The concrete walls of check dams are considered a physical barrier for aquatic and semiaquatic animals that inhabit mountain streams. Traveling behaviors around concrete check dams by the Japanese water shrew Chimarrogale platycephalus, a semi-aquatic mammal, were directly observed via radio-tracking in Kamikoshi Stream in central Honshu, Japan. Traveling behaviors were mainly observed on the wet ...

- Abstract:
- ... Large quantities of contaminated river sediment is dredged continuously worldwide, which is generally dumped in landfill areas resulting in land occupation and soil-groundwater pollution. An innovative approach is demonstrated in this study to transform contaminated sediment into eco-friendly foamed concrete by adding cement, foam and silica fume without heating and pressure. With the foam percent ...

- Abstract:
- ... Ultra-lightweight foamed alkali-activated concrete based on river sediment-metakaolin blends was prepared by the mixed foaming method of chemical foaming. Polluted river sediment is transformed into eco-friendly foamed concrete without heating and pressure. The results showed that ultra-lightweight foamed concrete presented its dry density between 100 and 600 kg/m³, the thermal conductivity betwee ...
