Salt-marsh plants play important roles in the hydrodynamics and sediment transport deposition processes coastal regions. The Delft3D model was applied to quantify influence of salt-marsh on hydrodynamic characteristics suspended a wetland, reveal contribution trapping local area. Specifically, spatial distributions were acquired from remote sensing images coupled with model. A comparison showed...

Deltas and estuaries worldwide face the challenge of capturing sufficient sediment to keep up with relative sea-level rise. Knowledge about pathways fluxes is crucial combat adverse effects on channel morphology, for example, erosion which enhances bank collapse increasing tidal penetration. Here, we construct budgets quantify annual changes urbanized Rhine-Meuse Delta Netherlands, a typical ur...

Hydrologic alternation of river systems is an essential factor human activity. Cascade-dammed waters are characterized by the disturbed outflow material from catchment. Changes in sediment, dissolved load and nutrient balance among base indicators water resource monitoring. This research was based on use hydrological quality data (1984–2017) Indicators Alteration (IHA) method to determine influ...

PURPOSE: The Coastal and Hydraulics Engineering Technical Note (CHETN) herein describes a method for estimating the percentage of sand-sized material placed in suspension by breaking waves and carried by a cross-channel current to either fall into a navigation channel or travel across it. Required inputs are channel width and depth, depth in the vicinity of the channel, depth-averaged current v...

A long-term goal of our sediment transport and deposition investigations is to link sediment-transport processes to the formation and preservation of event beds in sediment deposits. The general aim of this project is to investigate how forcing processes affect the sediment-transport dynamics that act to effect the delivery and retention of fine-grained sediment through tidal rivers and in shal...

The hatching of cladoceran ephippia from a 15-cm long sediment core was investigated, and Ceriodaphnia quadrangula clones were isolated from different sediment layers. Bosmina microfossil data were also analyzed, and compared with the corresponding data from a Pb210 dated core, which allowed us to infer the age of the sediment layers. Using changes in Bosmina microfossil morphologies, we were, ...

The pollution level of Lake Bafa was investigated by collecting fish samples {Dicentrarchus labrax (sea bass), Liza ramada (mullet) and Anguilla anguilla (eel)}, surface sediment, and core samples. In all these samples, 210Po and 210Pb concentrations were estimated, and total annual dose rates were obtained for each species. Some heavy metal (Cr, Ni, Pb, Cd, Mn, Fe, and Zn) concentration levels...

Water is an important natural element of our environment, and its management security are also serious concerns. Agricultural non-point source pollution (NPSP) one the major sources contaminants causing water quality degradation. A riparian buffer zone a vegetative cover adjacent to channels that positively contributes pollutant filtration sediment trapping. It has potential filter nutrients, r...
