In this study, a series of laboratory tests were performed to investigate the effects side ramp slope, crest length, and porous media properties on flow regimes, water-surface profiles, discharge coefficients, energy dissipation in embankment gabion weirs with upstream downstream slopes. 24 physical models solid three different upstream/downstream slopes (90°, 45° 26.5°) created. To complexity ...

The goals of this study are to develop models of radiative transfer for optically shallow waters with benthic substrates colonized by submerged aquatic vegetation (SAV). The models will enable prediction of upward spectral radiation from the seafloor, thereby permitting (i) the use of optical remote sensing to retrieve bathymetry, (ii) the search for submerged objects of anthropogenic origin an...

the rectangular broad crested weirs are widely used to measure the water dischargewhich is one of the most popular tools in the irrigation canals particularly, in developingcountries.the present article is trying to demonstrate the results of an experimental work carriedout on rectangular broad crested weir with sloped upstream face to investigate the effect ofupstream slope on discharge effici...

conclusions: the hereditary stability analysis of the uv mentioning 45 minutes revealed the uv exposure time for mutants and 3 represented the colony taken from the plate irradiated for 45 minutes mutant showed that the production of avermectin b1b remained constant and no reverse mutation occurred after 15 generations. results: avermectin b1b-hyper-producing mutant, produced using these three ...

Various problems involving the interaction of water waves with thin plates are reduced to hypersingular boundary integral equations. Examples include scattering by submerged curved plates and by surface-piercing plates, in two dimensions; trapping of waves by submerged plates; and scattering by submerged flat plates in three dimensions. Each integral equation is solved numerically, using an exp...
