Abstract Hydrological and sedimentological data were collected on several cross-sections of both natural artificial canals three cutoff meanders (Mahmudia, Dunavăţul de Sus, Jos meanders) the Sfântu Gheorghe branch at beginning June 2017. The hydrological shows a heterogeneous distribution water discharges: Mahmudia Jos, most liquid flow passes through channels. In case Sus meander, cut meander...

Reservoir architecture is an important basis for studying the sedimentary evolution of underground reservoirs and distribution remaining oil. Taking meander-river reservoir Guantao Formation in Chengdao Oilfield as example, characteristics subsurface meander-belt deposits were studied by seismic sedimentology. Seismic lithology performed using -90° phase wavelet frequency fusions; geomorphology...

We report on the effect of anisotropy on the step meandering instability on vicinal surfaces during molecular beam epitaxy growth. A scenario of interrupted coarsening is found: the lateral length scale of the structure first significantly increases with time and then freezes at a larger length scale. The wavelength selection mechanism results from a nontrivial nonlinear effect of anisotropy. A...
