Stratigraphic evolution of Las Vegas Bay, Lake Mead, Nevada: 1935--2002
… effects changes in lake level, sediment supply, fluvial discharge and basin physiography have had on stratigraphy of the basin. Mapping, seismic, sidescan sonar and bathymetry surveys, in conjunction with sediment cores, LPSA and 137Cs analyses were integrated to develop a temporal basin filling …

Evolution and Architecture of an Incised Valley in the Upper Cretaceous Eagle Formation in South-Central Montana
… (SB), and transgressive surface of tidal-fluvial erosion (TSE). Within this sequence stratigraphic framework, 4 facies association, internal lower-order architectures (i.e. channel forms, lateral accretion sets, crevasse splays) and higher-order regional surfaces (i.e. sequence boundaries) …

The Twiggs Clay: mineralogy, origin, and industrial properties of an upper Eocene opaline claystone in the coastal plain province of Georgia, U.S.
… and Central America contributed nutrients, and fluvial discharge locally enhanced nutrient levels. Diagenetic transformation of amorphous silica to disordered, lepispheric silica occurred through in-situ dissolution and re-precipitation at relatively low temperatures. Reactions between clay …

Depositional Environments and Sequence Stratigraphy of Upper Mississippian Strata in the Central Appalachian Basin
… of semimonthly cycles is ascribed to seasonal fluvial discharge. Meter-scale, multi-year cycles may reflect the 18.6-year lunar nodal cycle. Sequence development likely reflects fourth-order (~400 k.y.), Gondwanan glacioeustatic cycles. The character and relative stratigraphic position of …

Process Sedimentology and Three-Dimensional Facies Architecture of a Fluvially Dominated, Tidally Influenced Point Bar: Middle McMurray Formation, Lower Steepbank River Area, Northeastern Alberta, Canada
… these facies are interpreted to represent a fluvially dominated, tidally influenced point bar that experienced strong seasonal variation in river discharge. Annual fluctuations between river-flood stage and low-flow stage are responsible for the deposition of fluvially dominated sand beds …

The gulf of cadiz as a natural laboratory for the validation and exploitation of coastal altimetry and model data
… with the aim of studying the influence of its discharges on the sea level variability. Details of the Delft3D FLOW module implementation are given in the manuscript. The model was calibrated and validated along the river estuary comparing the output with in-situ observations of water level and …
