This study provides an initial assessment of suspended sediment transport in three rivers on the Alaska North Slope. From 2011 to 2013, the Anaktuvuk (69◦27′51.00′ ′ N, 151◦10′07.00′ ′ W), Chandler (69◦17′0.30′ ′ N, 151◦24′16.14′ ′ W), and Itkillik (68◦51′59.46′ ′ N, 150◦2′24.00′ ′ W) Rivers were monitored for a variety of hydrologic, meteorologic, and sedimentologic characteristics. Watershed ...

Sidescan sonar detects objects buried in the seafloor through generating images of ordnance such as seamine buried in sediments. The sonar operates by illuminating a broad swath of the seabed using a line array of acoustic projectors while acoustic backscattering from the illuminated sediment volume is measured. The effect of suspended sediment on the sonar imagery depends on the volume scatter...

Our research approach combines advanced observational and modeling techniques. In the field, we will measure velocity and suspended sediment at high resolution (~ few cm) in shallow flows, tracking the evolution of the salinity front through the tidal cycle. The instrumentation will incorporate an acoustic Doppler current profiler (ADCP) to measure currents and a profiling conductivitytemperatu...

The Burdekin River catchment ( 130,400 km) is a seasonally dry tropical catchment located in north-east Queensland, Australia. It is the single largest source of suspended sediment to the Great Barrier Reef (GBR). Fine sediments are a threat to ecosystems on the GBR where they contribute to elevated turbidity (reduced light), sedimentation stress, and potential impacts from the associated nutri...

abstract lateral intake is a hydraulic structure which is used for diversion of some portion of water from a river for the purpose of irrigation, storage and industrial. most of lateral intakes from canal are installed at canal with inclined banks which has not received the attention of the researchers in the past. since the flow discharge and sediment which enters the intake canal depends on t...

identifying sediment sources is one of important factors in selecting of appropriate method of erosion control and soil conservation. the main objective of this study is to estimateuncertainty and contribution of forest roads to sediment yield in ziarat drainage basin, gorgan city using geochemical tracers. for this purpose, 47 soil samples were collected from different sources with different l...

The sediment flux through Himalayan rivers directly impacts water quality and is important for sustaining agriculture as well as maintaining drinking-water and hydropower generation. Despite the recent increase in demand for these resources, little is known about the triggers and sources of extreme sediment flux events, which lower water quality and account for extensive hydropower reservoir fi...

The surface erosion area in the Yangtze River basin increased from 364×10 3 km 2 in the 1950s to 707×10 3 km 2 in 2001 due to a great increase in population. Based on the regression relationship between surface erosion area and population, the surface erosion area was predicted to be about 280×10 3 km 2 at the beginning of the 20 th century. The sediment yield, which increased by about 30% duri...

The phosphorus content of fluvial sediment (suspended sediment and the < 63 microm fraction of floodplain and channel bed sediment) has been examined in contrasting rural (moorland and agricultural) and industrialized catchments in Yorkshire, UK. The River Swale drains a rural catchment with no major urban and industrial areas, and the total phosphorus (TP) content of fluvial sediment is genera...
