Horizontal water trap for measurement of aeolian sand transport

Horizontal water trap for measurement of aeolian sand transport
A new type of horizontal trap was developed for measuring the aeolian sand transport rate on a flat surface. The trap consists of an adjustable frame that is embedded level with the sand surface, into which a plastic liner is installed and filled
with water to capture the blown sand. The water trap has high efficiency and does not disturb the wind field or induce upwind scour. Deployment on Padre Island, Texas, indicated that this portable and adjustable trap catches and retains all the sand blown

Trapping of airborne dust by mosses in the Negev desert, Israel

Trapping of airborne dust by mosses in the Negev desert, Israel
The AA. have chosen a site which is much drier (70 mm mean annual rainfall) than the main zone of loess sedimentation (Yaalon and Dan, 1974) to study dust trapping. The mosses grow over the particles covering them and trap additional dust

Reservoir trap efficiency in Erosion and sediment yield : some methods of measurement and modelling.

Reservoir trap efficiency in Erosion and sediment yield : some methods of measurement and modelling.
An explanation of what happens in agricultural reservoirs during an inflow event and, using a flow diagram, the various parameters that influence sediment trap efficiency.

Relations of sand trapping efficiency and migration speed of transverse dunes to wind velocity

Relations of sand trapping efficiency and migration speed of transverse dunes to wind velocity
A self-consistent model which describes transverse dune migration in equilibrium is introduced. It shows that an equilibrium expression for dune migration speed (Cd) must take into account sand trapping efficiency (Te), and that Te is strongly

Observations of trapped waves in the atmosphere and ocean along the coast of southern Africa

Observations of trapped waves in the atmosphere and ocean along the coast of southern Africa
The coastally trapped low pressure cell and associated shelf wave which travel eastward along the southern edge of the African continent are studied. Composite and case study analyses confirm a geographically anchored acceleration of the coastal low

Design and calibration of a recording bedload trap

Design and calibration of a recording bedload trap
This paper reports design modifications to the recording bedload trap developed by Reid et al. (1980), and rigorous calibration procedures followed both before and after installation. An unexpected temperature dependence of the trap and stage

Wind tunnel evaluation of a wedge-shaped aeolian sediment trap

Wind tunnel evaluation of a wedge-shaped aeolian sediment trap
A detailed set of tests in a wind tunnel investigated the characteristics of flow and sampling efficiency of a low cost sediment trap that can be used in wind tunnels and field applications. Results indicate that this trap, and others that have wide

Hydrodynamische Fallen-Erscheinungen und Ursachen. (Pièges hydrodynamiques-les phénomènes et leurs causes)

Hydrodynamic traps are characterized by low velocity of fluid filtrations in regions of relativily low pressure potentials and by not-horizontal contacts of oil and water or gas and water. Typical hydrodynamic traps are also those, which are to find
in the flanks of anticlines and monoclines or in structurally noses of terraces, holding by hydrodynamic forces. The research of such traps is only possible by use of a complex of special geological and hydrodynamical methods. Of course, here it is necessary
to combinated these methods with those for study of oil and gas reservoirs by petroleum engineering. In future the hydrodynamic traps will be have a great lot of oil and gas potential for the humanity. When the use of oil and gas in all countries is growing
in the same way how in past, so the hydrodynamic traps in far future can be to obtain the first place in the discovery of oil and gas fields.

Measured hillslope erosion rates in the wet-dry tropics of Cape York, northern Australia Part 1 : A low cost sediment trap for measuring hillslope erosion in remote areas — Trap design and evaluation

Measured hillslope erosion rates in the wet-dry tropics of Cape York, northern Australia Part 1 : A low cost sediment trap for measuring hillslope erosion in remote areas — Trap design and evaluation
The AA. present a design for a low budget and low maintenance hillslope sediment trap (HST) that has successfully been deployed to measure gross annual hillslope sediment production (suspended and bedload) across 2 wet seasons in the Normanby
catchment, Cape York, North Queensland. The trap is evaluated under laboratory conditions prior to deployment in remote rangelands. Results show that the traps can empirically evaluate modeled hillslope erosion rates.

Design and field test of a continuously weighing, tipping-bucket assembly for aeolian sand traps
for the full duration of wind events, without the need to halt measurements and empty traps during the event.

Coastally trapped disturbances in the lower atmosphere : dynamic commonalities and geographic diversity

Coastally trapped disturbances in the lower atmosphere : dynamic commonalities and geographic diversity
These disturbances are trapped by the existence of a subsidence inversion at a height below the crest of barrier-like coastal mountains and propagate alongshore with the coast on the right (left) in the Northern (Southern) Hemisphere. It is shown
