Abstract:

Concern has been expressed regarding the impacts of climate change on river ice and ice jam formation in cold regions. Ice jams are easily initiated in bends and narrow channels and cause disasters. In this study, observations and remote sensing monitoring are used to study the freeze-up ice jam formation of bends. Sediment transport and freezing process of the river interact, influencing bed changes profile and sedimentary budget. River ice processes, channel evolution, ice hydro-thermodynamics, and ice jam accumulation are explored. The results show that the channel topography determines the

Abstract:

AbstractAlthough the hydrodynamics of river meanders are well studied, the influence of curvature on flow in estuaries, with alternating tidal flow and varying water levels and salinity gradients, is less well understood. This paper describes a field study on curvature effects in a narrow salt-marsh creek with sharp bends. The key observations, obtained during times of negligible stratification, are 1) distinct differences between secondary flow during ebb and flood, with helical circulation as in rivers during ebb and a reversed circulation during flood, and 2) maximum (ebb and flood) streamw

Abstract:

Trees have been used extensively by river managers for improving the river environment and ecology. The link between flow hydraulics, bed topography, habitat availability, and organic matters is influenced by vegetation. In this study, the effect of trees on the mean flow, bed topography, and bed shear stress were tested under different flow conditions. It was found that each configuration of trees produced particular flow characteristics and bed topography patterns. The SR (single row of trees) model appeared to deflect the maximum velocity downstream of the bend apex toward the inner bank, w

Profiles of salinity, temperature, and turbulent kinetic energy dissipation (ε) were collected for a tidal cycle across the estuary with a microstructure profiler.

Abstract:

Among all the means of transportation, road has been described as the most important, probably because of its flexibility and its low cost in terms of construction, maintenance and usage. However, in Nigeria, road is considered to be the most dangerous means of transportation because of their bad nature such as sharp bends, narrow bridges, steep slopes and other related problems which are associated with the terrain where these roads are constructed. Road transportation therefore needs proper planning and development through the use of geo-information technologies that would ease accessibility

Abstract Flow dynamics and sediment transport in a river bend have recently been studied using experimental and numerical investigations. A three-dimensional numerical modeling model named NaysCUBE was used in this study to describe the flow pattern and process of sediment transport in a sharp river bend as a complement to the prior work of the physical hydraulic model. The model uses the RANS equation to simulate flow where a fully complex 3D flow is governed. Despite the limitations of the RANS model, NaysCUBE well reproduces the flow pattern and turbulence phenomena in a movable bed channel

Abstract:

Abstract The peculiarity of small rivers is the dependence of erosion-accumulative processes in their beds on the intensity of soil erosion in the catchment area: the smaller the river, the greater the contact with the catchment area of its channel, where mineral particles, washed off from its area, directly enter it. Soil erosion leads to the entry of an excessive amount of them into the channel of a small river, as a result of which sediment accumulation begins in it, siltation of the channel occurs. It leads to changes in the water regime of small rivers - a decrease in inter-soil runoff (u

Abstract:

Water transport, both sea and inland, is the cheapest, least invasive, and safest option for non-standard loads; hence, it is important to increase the percentage share of inland waterway transport on the rivers of Central and Eastern Europe. Transporting cargo is particularly difficult on shallow waterways because rivers overloaded with sediment determine the vertical parameters on inland waterways. A ship’s safe manoeuvrability depends on the available water depth of the navigational area concerning the vessel’s draught. The draught is related to channel depth and sediments. The paper presen

The optimization of M-Sand with silica fume as a partial replacement for natural sand is discussed in this work. Compressive and split tensile strengths of concrete mixtures were assessed.

Abstract:

The analysis of satellite imageries and topographic maps of different dates revealed that the Narayani River near Mangalpur migrated about 32 km to the west. Its westward shift is also clearly evidenced by the continuation of wetlands parallel to the main river course. The interpolated contours of 2 m interval obtained from the topographic map of 1:25,000 scale also revealed many parallel depressions. These depressions belong to an old abandoned channel, and are closely associated with a sharp bend of the Narayani River. There is a high possibility of breaching a weak and unconsolidated natura

Abstract:

Abstract The ‘Bajo Grande’ Wastewater Treatment Plant has a design capacity of 2.78 m3/s, and discharges into the Suquia River (Córdoba, Argentina). The river has an average flow rate of 10 m3/s, with lower values during the summer. Currently, the treatment plant does not have an accurate discharge-measurement system prior to the discharge into the river, which makes it difficult to evaluate the dosing of the disinfection treatment. The outflow rate is measured in a straight flume. However, at the inlet section of the flume, a 180° sharp bend induces a complex turbulent flow with instabilities

Abstract:

In the Kharidhunga-Thokarpa area, the rocks of Lower Nawakot Group are exposed. The lowermost unit of the study area is the Kuncha Formation. It is composed of a more than 2,500 m thick monotonous sequence of grey to green phyllite, quartzite, and 'gritty' phyllite. Green-grey quartzite is seen in the upper part of the formation. Small (0.5 mm) garnets of brown colour occur in the upper part of the formation. The Fagfog Quartzite has a sharp contact with the underlying Kuncha Formation and consists of fine- to coarse-grained pure white quartzite with thin to very thin bands of grey and green p

Abstract:

We take as our subject what many would deem a waste of good celluloid: the degraded cultural form of the stoner film. Stoner films plot the experiences of the wasted (those intoxicated on marijuana) as they exhibit wastefulness—excessiveness, improvidence, decay—on a number of fronts. Stoners waste time in constantly hunting for pot and in failing to pursue more productive activity whilst wasted. Stoners waste their minds, both literally, if we believe contested studies that indicate marijuana smoking kills brains cells, and figuratively, in rendering themselves cognitively impaired. Stoners w
