Fluvial in the context of "Thalweg"

The Gulf of Drin or Bay of Drin (Albanian: Gjiri i Drinit or Pellgu i Drinit) is an ocean basin of the Adriatic Sea within the Mediterranean Sea along the northern coast of Albania. Roughly scythe-shaped, it extends immediately from the Delta of the Buna in the north, across the port city of Shëngjin, to the Cape of Rodon in the south. The shoreline of the gulf is a shallow combination of sandy beaches, sand dunes, capes, salty and fresh water wetlands, estuaries, pine and coastal forests, reed beds and coastal meadows.

The shoreline of the gulf has a length of approximately 60 kilometres and is dotted with cliffs and beaches fed by fluvial imputes. The region is drained by numerous rivers and has formed a characteristic ecosystem and biodiversity. It is named after the Drin River that runs through a mountainous area towards the coast, however, the Ishëm and Mat also drain into the gulf. In consideration to the flat landscape, the gulf's shoreline are dotted with extensive wetlands and lagoons that continuously change in size and shape.

A liman is a wide estuary formed as a lagoon at the mouth of one or more rivers where flow is constrained by a sediment bar created by sea or river current. The hydrological term comes from the Russian language and is used in various national and regional languages for estuary lagoons all around the Black Sea and Sea of Azov coasts.

A liman is classified as either maritime or fluvial: "maritime" if its sediment bar was formed by sea current; "fluvial" if the bar is created by obstructed flow in a saturated river.

Planetary geology, alternatively known as astrogeology or exogeology, is a planetary science discipline concerned with the geology of celestial bodies such as planets and their moons, asteroids, comets, and meteorites. Although the geo- prefix typically indicates topics of or relating to Earth, planetary geology is named as such for historical and convenience reasons; due to the subject matter, it is closely linked with more traditional Earth-based geology.

Planetary geology includes such topics as determining the properties and processes of the internal structure of the terrestrial planets, surface processes such as volcanism, impact craters, even fluvial and aeolian action where applicable. Despite their outermost layers being dominated by gases, the giant planets are also included in the field of planetary geology, especially when it comes to their interiors. Fields within Planetary geology are largely derived from fields in the traditional geological sciences, such as geophysics, geomorphology, and geochemistry.

A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes, with little or no vegetation, are called ergs or sand seas. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the stoss (upflow) side, where the sand is pushed up the dune, and have a shorter slip face in the lee side. The valley or trough between dunes is called a dune slack.

Dunes are most common in desert environments, where the lack of moisture hinders the growth of vegetation that would otherwise interfere with the development of dunes. However, sand deposits are not restricted to deserts, and dunes are also found along sea shores, along streams in semiarid climates, in areas of glacial outwash, and in other areas where poorly cemented sandstone bedrock disintegrates to produce an ample supply of loose sand. Subaqueous dunes can form from the action of water flow (fluvial processes) on sand or gravel beds of rivers, estuaries, and the sea-bed.

Accommodation in geology is the space that is available for the deposition of sediments. A fundamental concept in sequence stratigraphy, accommodation can be construed as the volume between the actual surface and the theoretical equilibrium surface where deposition and erosion are in balance at every point. In marine environments, this equilibrium level is sea level.

In marine environments, changes in accommodation on long temporal scales are mainly determined by tectonics or by changes in eustatic sea level. In fluvial environments, changes in accommodation are controlled by the gradient, discharge and sediment supply. In the lower parts of river systems, the change of accommodation in the fluvial system is controlled by the changes in marine accommodation.

The Chinle Formation is an Upper Triassic continental geological formation of fluvial, lacustrine, and palustrine to eolian deposits spread across the U.S. states of Nevada, Utah, northern Arizona, western New Mexico, and western Colorado. In New Mexico, it is often raised to the status of a geological group, the Chinle Group. Some authors have controversially considered the Chinle to be synonymous to the Dockum Group of eastern Colorado and New Mexico, western Texas, the Oklahoma panhandle, and southwestern Kansas. The Chinle Formation is part of the Colorado Plateau, Basin and Range, and the southern section of the Interior Plains. A probable separate depositional basin within the Chinle is found in northwestern Colorado and northeastern Utah. The southern portion of the Chinle reaches a maximum thickness of a little over 520 meters (1,710 ft). Typically, the Chinle rests unconformably on the Moenkopi Formation.

The Chinle Formation was probably mostly deposited in the Norian stage, according to a plethora of chronological techniques. It is a thick and fossiliferous formation with numerous named members (subunits) throughout its area of deposition.
