MORPHODYNAMIC ANLYSIS OF WIND FACES USING SPATIAL SAND ROSE MODEL IN ZABOL AND ZAHAK REGION, IRAN
The majority of Iran’s area is covered by arid and semiarid climates. In these areas, wind causes more erosion compared to water. Therefore, determination of wind characteristics especially its velocity is very important. One of the simplest methods that can supply researchers with the origin of wind erosion in the shortest time is synthesizing sand rose model and interpretation of aerial photo...
متن کاملMorphodynamic processes in shallow estuaries: influence of tidal flats and channels on sand transport
Flood/ebb-dominance in net sediment transport of shallow sandy estuaries with tidal flats and channels (typical around the U.K.) is investigated using a 2D model (TELEMAC). The micro-tidal Dyfi Estuary is used as a case study. The along-estuary net sediment transport in the Dyfi has been predicted and characterised as ebbor flood-dominant. The simulations illustrated that shallow waters (inner-...
متن کاملTide-driven deep pore-water flow in intertidal sand flats
Sulfidic seeps with methane ebullition were observed at the low-water line of intertidal sand flats at a number of locations in the Wadden Sea. Bioturbating fauna was absent in the seep areas but abundant in the more central areas of the tidal flat. At one site, the vertical methane and sulfate distribution in pore water was determined along transects from the low-water line toward the interior...
متن کاملBiofilm origin of clay-coated sand grains
The presence of clay-sized particles and clay minerals in modern sands and ancient sandstones has long presented an interesting problem, because primary depositional processes tend to lead to physical separation of fineand coarse-grained materials. Numerous processes have been invoked to explain the common presence of clay minerals in sandstones, including infiltration, the codeposition of floc...
