1 2 This study investigated if siltation-associated changes in the sediments are 3 detrimental to seagrasses. We chose Cymodocea rotundata as the test species because it 4 is considered one of the Southeast Asian seagrass species most sensitive to siltation. The 5 approach included the (1) evaluation of the effects of silted sediments on plant growth, 6 evaluation of the effects of in situ sulf...

The deposition of the instantaneously released sediment into a gravel matrix and the hydraulic resistance induced by the rapid siltation are investigated herein. The experimental results reveal that the depositional patterns of the sediment are governed by the gravel-sediment size ratio, the amount of sediment released, and the seepage flowrate. The observations also indicate that the stable st...

Between March and November 1984, Silver Creek, a small tributary of the Mahoning River in northeastern Ohio, eroded into and through a small lacustrine deposit of glacial silt. During this erosional/ siltation episode, the stream was very turbid and siltation was observed at least 5 km below the source of silt. Only a few individuals of the caddisfly, Neophylax, the mayflies, Isonychia and Sten...

Soil erosion is a major factor leading to dams’ siltation and reducing their storage capacity. This study mapped the hot spots of soil areas predict erosion/siltation in Ghiss basin/dam (northeastern Morocco). In this context, various data has been prepared geographical information system for estimation by integrating universal loss equation (USLE). The result revealed that rate ranges between0...

An innovative remote sensing approach that combines land-use change and water quality information is proposed in order to investigate if Artisanal and Small-scale Gold Mining (ASGM) area extension is associated with water siltation in the Tapajós River Basin (Brazil), containing the largest small-scale gold mining district in the world. Taking advantage of a 40-year period of the multi-satellit...

This study constructs a digital elevation model of the coastal waters Shandong Peninsula using GIS-based interpolation methods to investigate 15-year characteristics seabed scouring and siltation. It utilizes depth data Peninsula’s offshore area between 2004 2006 2017 2019. The results indicated that coastal-water is characterized by integral siltation local point scouring. In addition, northwe...
