Tidal modulated flow and sediment flux through Wax Lake Delta distributary channels: Implications for delta development [PDF]

Proceedings of the International Association of Hydrological Sciences, 2015
In this study, a Delft3D model of the Wax Lake Delta was developed to simulate flow and sediment flux through delta distributary channels. The model was calibrated for tidal constituents as well as velocity and sediment concentration across channel ...

Fine description method of the underwater distributary channel in a braided river delta front: A case study of the first Member of the Dongying Formation in the M Oilfield, Nanpu Depression

地质科技通报, 2023
The division accuracy of a single-genesis sand body in a river channel determines the evaluation resolution of residual oil content and limits the efficiency of oil production.

Steadiness of the distribution of residual oil in the delta sequences of the Paleogene system of the Bohai Bay basin [PDF]

Нефтегазовая геология: Теория и практика, 2022
The deltas developed widely in several faulted basins in China. As a kind of important oil and gas reservoir, it is very necessary to make clear the internal architecture for prediction of the residual oil distribution in the late period of oilfield ...

Infilling Abandoned Deltaic Distributary Channels Through Landward Sediment Transport [PDF]

Journal of Geophysical Research: Earth Surface, 2020
AbstractUpon avulsion, abandoned deltaic distributary channels receive water and sediment delivered by a tie channel, overbank flow, and by tidal inundation from the receiving basin. The transport and deposition of sediment arising from this latter input have important impacts on delta development yet are not well constrained from field observations or

Flow Loss in Deltaic Distributaries: Impacts on Channel Hydraulics, Morphology, and Stability [PDF]

Water Resources Research, 2020
AbstractThe most comprehensive data sets documenting hydraulic and sediment transport regimes in the lower reaches of alluvial rivers come from systems that are managed to prevent flow loss from the channel into the overbank environment. Even moderate losses can have significant impacts on in‐channel velocity and sediment transport; therefore, a full ...

Channel Planform Dynamics along Distributary Channels: Case Study of the River Nun a Major Distributary of the River Niger

Journal of Geography, Environment and Earth Science International, 2019
Channel planform dynamics were analyzed for the River Nun; a major distributary of the River Niger from 1985 to 2015 using GIS and Remote sensing applications. Satellite imagery of the area from 1985, 1995, 2005, and 2015 were analyzed by means of GIS and used to determine the planform characteristics and changes in width, sinuosity, and shoreline ...
