The natural resources of Himalayas in terms of hydro power generation are not only crucial for the Himalayan states of India, but very important for the whole country. These states seem to be keen in exploiting their vast hydro electricity potential for net revenue earning. However, due to weak geological conditions and steep slopes these rivers carry a huge quantity of sediment with them. The ...

Sediment rating curve (SRC) is a conventional and a common regression model in estimating suspended sediment load (SSL) of flow discharge. However, in most cases the data log-transformation in SRC models causing a bias which underestimates SSL prediction. In this study, using the daily stream flow and suspended sediment load data from Shalman hydrometric station on Shalmanroud River, Guilan Pro...

Appropriate descriptions of turbulence are important in predicting sediment transport and seabed evolution. We use here a three-dimensional model to investigate the impacts of sediment-induced stratification, erosion parameterization, and turbulence closures on sediment transport and morphological simulations. The model is implemented in the Proudman Oceanographic Laboratory Coastal Ocean Model...

the devastating impact of land use change in the watershed is increasing the generation rate of sediment and entrance to rivers and sedimentation in reservoirs. according to this, studying on impact of land use change on hydrological process is necessary. aim of this study was investigating the impact of land use change on suspended sediment during 1994 to 2010 by swat model in dinevar watershe...

We determined the extent that a riparian buffer reduces stream suspended sediment concentrations by filtering road runoff during 18 rain events in a 2.5-ha, multi-use watershed in northern Thailand. The dominant buffer species was the perennial sedge Fimbristylis aphylla Zoll. ex Steud. (Cyperaceae). We monitored stream sediment concentration for situations where road runoff either flowed into ...

Worldwide, increasing coastal development has played a major role in shaping coral reef species assemblages, but the mechanisms underpinning distribution patterns remain poorly understood. Recent research demonstrated delayed development in larval fishes exposed to suspended sediment, highlighting the need to further understand the interaction between suspended sediment as a stressor and energe...

[1] During a major flood event, the inundation of urban environments leads to some complicated flow motion most often associated with significant sediment fluxes. In the present study, a series of field measurements were conducted in an inundated section of the City of Brisbane (Australia) about the peak of a major flood in January 2011. Some experiments were performed to use ADV backscatter am...

Swash zone sheet flow and suspended sediment transport rates are estimated on a 14 coarse sand beach constructed in a large-scale laboratory wave flume. Three test cases under 15 monochromatic waves with wave heights of 0.74 m and wave periods of 8 and 12.2 s were 16 analyzed. Sediment flux in the sheet flow layer exceeds several hundred kg m s during both 17 uprush and backwash. Suspended sedi...

Historical flow and suspended-sediment transport data from more than 2,900 sites across the United States have been analyzed in the context of estimating flow and suspended-sediment transport conditions at the 1.5-year recurrence interval flow (Q1.5). This is particularly relevant with the renewed focus on stream restoration activities and the urgency in developing water-quality criteria for se...

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 ...
