Controls on aeolian sand sheet formation exemplified by the Lower Triassic of Helgoland,d. Preservation of the aeolian deposits records the overall low-energy of the littoral processes, and early cementation. The aeolian deposits define sedimentary cycles of various thickness, and it is suggested that the cyclicity records Early Triassic orbital climatic forcing.作者: averse 時間: 2025-3-22 15:18 作者: 受辱 時間: 2025-3-22 18:36 作者: legislate 時間: 2025-3-22 21:50 作者: Hormones 時間: 2025-3-23 04:25

The grain size 400 μm is a threshold: the upper limit of actual, average aeolian deflation..This area, which previously had a positive sediment balance, during the last drought combined with agricultural overuse became an area of sand and dust removal with a negative sediment balance.作者: 榨取 時間: 2025-3-23 09:06
Controllership im internationalen Vergleich. The present rate of coastal retreat is about 1 to 2 m a year. The coastal erosion rates now observed can be used to estimate the rate of intrusion of sand inland from the coast. Measurements with sand traps and by cartographic comparison give an eastward aeolian flux estimated of between 15 and 30 m. a year per m length of foredune.作者: 排斥 時間: 2025-3-23 12:57

Distributional shape triangles with some applications in sedimentology, hyperbolic shape triangle and the beta shape triangle provide useful information on variations of grain size distributions, in cross-shore transects. This information can be related to the process-oriented erosion/deposition model developed previously in connection with the hyperbolic shape triangle.作者: IST 時間: 2025-3-24 03:06 作者: 大量殺死 時間: 2025-3-24 07:16 作者: Sputum 時間: 2025-3-24 10:47

Since the beach sediments consisted of well-sorted and very well-sorted fine sands, partly reworked from the dunes during the storm surge, deflation was not grain-size selective during the period of post-surge dune recovery.作者: 結束 時間: 2025-3-24 22:27 作者: 額外的事 時間: 2025-3-25 01:25
On the temporal-spatial variation of sediment size distributions, proposed and investigated. The model is closely related to the logarithmic hyperbolic distribution and preserves the hyperbolic shape of log-size distributions. In order to facilitate specification of the model in applications the concept of a ‘local erosion time’ is introduced. The local erosion t作者: SLAY 時間: 2025-3-25 06:18

Coastal erosion and aeolian sand transport on the Aquitaine coast, France,nes: parabolic dunes, barchans, round dunes and the foredune. All the dunes were constructed by westerly winds, blowing off the sea. Dating of these dunes is based on paleosols of the Great Dune of Pilat, the highest dune in Europe.

The aeolian deposits formed during lake low-stands, and sand sheet formation was caused by a restricted sand supply perhaps in combination with frequent wind changes and high-speed wind events.
