Wind control on the accumulation of heavy metals in sediment of Lake Ulubat, Anatolia, Turkey [PDF]

open access: yes, 2009
Freshwater Lake Ulubat (zmean = 1.5-2.0 m and Area = ~138 km2), NW Anatolia, Turkey was filled in by fine-to-medium-grain silts during the late Holocene.

Effect of sediment load boundary conditions in predicting sediment Delta of Tarbela Reservoir in Pakistan

open access: yes, 2019
Setting precise sediment load boundary conditions plays a central role in robust modeling of sedimentation in reservoirs. In the presented study, we modeled sediment transport in Tarbela Reservoir using sediment rating curves (SRC) and wavelet artificial

Improvement of the ergonomical structure of Knapsack sprayer to propel cart sprayer (PCS) [PDF]

open access: yes, 2020
A sprayer is a device used to spray a liquid projection mostly used in agriculture crop used to apply such as pesticides. The sprayer’s usage are based on the type of the background of the farmers scale in agriculture. Large scale of farmers will use the

Quantifying temporal and spatial variations in sediment, nitrogen and phosphorus transport in stream inflows to a large eutrophic lake [PDF]

open access: yes, 2013
High-frequency sampling of two major stream inflows to a large eutrophic lake (Lake Rotorua, New Zealand) was conducted to measure inputs of total suspended sediment (TSS), and fractions of nitrogen and phosphorus (P).

Impact of Reduced Fluvial Sediment Supply on Saltwater Intrusion in the Yangtze Estuary

open access: yesEarth's Future, 2023
A decline of the fluvial sediment supply leads to coastal erosion and land loss. However, the fluvial sediment load may influence not only coastal morphodynamics but also estuarine hydrodynamics and associated saltwater intrusion.

A Gap-Filling Tool: Predicting Daily Sediment Loads Based on Sparse Measurements

open access: yesHydrology, 2022
Sediment load in streams is known as both a carrier and a potential source of contaminants, while sediment deposition can alter stream flow, stage and morphology, and thereby has broad impacts on stream hydrology, aquatic life, and recreation activity ...

Sensitivity of fluvial sediment source apportionment to mixing model assumptions: A Bayesian model comparison [PDF]

open access: yes, 2014
Mixing models have become increasingly common tools for apportioning fluvial sediment load to various sediment sources across catchments using a wide variety of Bayesian and frequentist modeling approaches.

The application of backpropagation neural network method to estimate the sediment loads

open access: yesMATEC Web of Conferences, 2017
Nearly all formulations of conventional sediment load estimation method were developed based on a review of laboratory data or data field. This approach is generally limited by local so it is only suitable for a particular river typology.

Application of Sediment Runoff Model to the Wlingi Reservoir Watershed, Indonesia

open access: yesCivil and Environmental Science Journal, 2020
Sedimentation is the main problem in Wlingi reservoirs. They are suffering from severe watershed erosion and a heavy load of volcanic ash ejected from the eruption of Mount Kelud.

Effects of Three Gorges Reservoir (TGR) water storage in June 2003 on Yangtze River sediment entering the estuary

open access: yes, 2006
International audienceThe world-greatest water conservancy project, Three Gorges Reservoir (TGR), stored water for the first time in June 2003, which provides an excellent opportunity to examine its effects on the sediment entering the Yangtze River ...
