A physical model study was conducted to examine the development of submerged sand erosion through a slot on a defective sewer pipe. Various parameters that affect the erosion process were studied, including particle size, defect size, position on the pipe, and water depth. This experimental study used particle image velocimetry analysis to provide a deeper understanding of the mechanism of ...

submerged breakwaters and the sand transport along the Songdo beach. For these reasons, fiveyear monitoring () was carried out for the prediction of shoreline change and for the maintenance of shoreline of Songdo beach. On the basis of the accumulated monitoring data, we analyzed the sand movement in Songdo beach to predict beach erosion. The results reveals that beach erosion occurs ...

 · In this study, a mixture with sand, soil and fly ash (1:1:1) was selected as the base in bioretention systems with different structures and heights of submerged zone. The diversity of microorganisms in the used bioretention systems was analyzed using Miseq highthroughput sequencing to make sure the dominant microflora. Both urease and extracellular polymer (EPS) were also .

The Submerged Pond Sand Filter is built inside a pond and has a vertical as well as a horizontal flow of water through a sloped filter opening. The filter provides treated drinking water to a rural Indian village. The filter has functioned with minimal maintenance for five years without being subject to the typical scraping off and changing of sand as needed in traditional slow sand filters ...

We experimentally investigate submerged granular flows of hydrophobic and hydrophilic grains in a rotating drum. While slurry and suspension flows are common in nature and industry, effects of surface chemistry on flow behavior have received little attention. The experiment consists of a cylindrical drum containing various concentrations of hydrophobic and hydrophilic grains of sand submerged ...

over a submerged sand bar. The data with wave height of 10 cm and wave period of 1s was used for calibration. The model output obtained for water level and velocity for a depth of 20 cm 5 cm above the bottom at a distance of m from paddle was used to compare with measurements. The model results of velocity and water level showed good comparison with the measurements. The plots of ...

Generally saturated slopes of loose sand or siltysand and earth dams and embankment resting on loo cohesionless soil deposit are highly susceptible to liquefactioninduced damage and during strong earthquake several landslides caused soil liquefaction may occur.

Lowvisualimpact and more economical submerged breakwaters not only diminish strong water currents which protects beachfront structures and coasts from erosion but also function as marine ecology boosting artificial reefs to attract a myriad of organisms.

uniform coarse sand. A sketch of scouring at a submerged weir under livebed scour conditions is shown in Fig. 1, in which h a = average aggradation height; h 0 = average approach flow depth; h t = tailwater depth; H d = water level difference across the weir; z = weir height; d us = scour depth upstream of the weir; and d s = scour depth downstream of the weir. It is found that the scour ...
