Facies groups A and B are reservoir-prone. Facies Group A (gravels) have high porosity (40–50%) and generally high permeability (1-2 Darcies), although the moderate to very poor sorting decreases this value for some units. The structureless gravels have approximately equivalent kh and kv va...
Lake Pannon, covering the Pannonian Basin (Hungary) during the Late Miocene, had a complex lake bottom with deeper sub-basins and intrabasinal basement highs, sometimes emerging above the lake level as islands and peninsulas. Above structural highs, the basin fill sequence usually commenced with ...

The impoundment of the Three Gorges Dam on the Yangtze River begins in 2003 and a full pool level is first attained in 2010. This process leads to reciprocal adjustments in flow discharge, sediment transport and morphology downstream of the dam. Based on 26-year recorded hydrologic data 1990–...
Additionally, fractionation of environmental samples (i.e. sorting samples by particle size class) can produce significant differences in the metabarcoding results between fractions56,57 indicating significant variation within sites. We found similar patterns, with PERMANOVA modelling showing approximately ...

(Lu et al.2009; Al-Khashman2013; Chen et al.2013). AsIgeoand other similar metrics are based on simple ratios of a single element, they are vulnerable to distortion by particle size sorting effects and association of particular elements with particular mineral types (Bern et al.2019). A ...
(2394–2238 m) displays cyclic trends in Si/Al, Zr/Al, and Ti/Al ratios, reflecting the influence of sedimentary processes (e.g., sediment sources, provenance terrane, sediment sorting, and/or grain size distribution) and environmental conditions (e.g., sea level change, terrestrial/riverine...
Except for flow regime, streams that possess a comparatively low sediment supply are prone to exhibit a substantial level of armouring. Conversely, streams that experience adequately high sediment supply rates are unlikely to exhibit notable vertical sediment sorting and, as a result, are expected to...
