Abstract:
... Recycling of dredged sediment (DS), derived from the routine dredging operation of rivers, lakes and seas, into construction materials represents an eco-friendly way to alleviate the burden on the environment. At higher incorporation dosages, however, DS causes a dramatic reduction in the mechanical properties of the host materials, which greatly stymies a broader application. In this study, DS fr ...

Abstract:
... The sulfate evaporite minerals (gypsum and anhydrite) and brines of Jizan sabkha cause corrosion of the steel reinforcement and deterioration of the concrete, and consequently hinder the development activity for building new urban communities and industrial zones in Jizan area, Red Sea coastal plain of Saudi Arabia. The sabkha evaporite minerals below the sediment surface are represented by displa ...

... The surface infiltration rates (SIR) of permeable pavements decline with time as sediment and debris clog pore spaces. Effective maintenance techniques are needed to ensure the hydraulic functionality and water quality benefits of this stormwater control. Eight different small-scale and full-scale maintenance techniques aimed at recovering pavement permeability were evaluated at ten different perm ...

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 ...

... Roadside soils are heavily loaded with reactive nitrogen due to vehicular emissions, and these loadings likely acidify near-road soils. Cationic metals are mobilized from acidified soils during exchange reactions. Depletion of soil cation pools is well documented in forest soils, but poorly understood in roadside soils despite heavy nitrogen loadings to roadside environments and the continued grow ...

The on-land areas affected by the landslide have been restored and evidence of the landslide is mostly gone, but huge structures that appear to be man-made have been observed by divers on the seafloor near the area of the landslide. We used a fish finder designed for leisure use and oth ...

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:
... Outdoor residual sprays are among the most common methods for targeting pestiferous ants in urban pest management programs. If impervious surfaces such as concrete are treated with these insecticides, the active ingredients can be washed from the surface by rain or irrigation. As a result, residual sprays with fipronil and pyrethroids are found in urban waterways and aquatic sediments. Given the a ...

Abstract:
... Anthropogenic surficial deposits are formed from Holocene and older deposits that have been so modified by human activity that their original form is unrecognizable. Because their characteristics are fundamentally different from those of natural origin, the creation of special stratigraphic categories seems justified. Two new material categories are proposed for the stratigraphic classification of ...

This paper describes a proof of ...
