Analyses of suspended sediment loads in Slovenian rivers [PDF]

Hydrological Sciences Journal, 2016
ABSTRACTSuspended solids are present in every river, but high quantities can worsen the ecological conditions of streams; therefore, effective monitoring and analysis of this hydrological variable are necessary. Frequency, seasonality, inter-correlation, extreme events, trends and lag analyses were carried out for peaks of suspended sediment ...

Estimation of Suspended Sediment Load Using Artificial Intelligence‐Based Ensemble Model [PDF]

Complexity, 2021
Suspended sediment modeling is an important subject for decision‐makers at the catchment level. Accurate and reliable modeling of suspended sediment load (SSL) is important for planning, managing, and designing of water resource structures and river systems.

Suspended Sediment Estimation Using Machine Learning Methods [PDF]

Aerul şi Apa: Componente ale Mediului
Suspended sediment in rivers is important for efficiently using water resources and hydraulic structures. In this study, the suspended sediment load of rivers was estimated using traditional multi-linear regression (MLR), machine learning methods such as

Dynamic Characteristics of Suspended Load and Bed Load Transport in Meltwater Runoff of Qiyi Glacier

Shuitu Baochi Xuebao
[Objective] The transportation of sediment via glacial meltwater can not only reflect the glacial erosion and landform evolution, but also is one of the important sediment sources for the downstream river.

An expert integrative approach for sediment load simulation in a tropical watershed. [PDF]

, 2013
Prediction of highly non-linear behaviour of suspended sediment flow in rivers is of prime importance in environmental studies and watershed management. In this study, the predictive performance of artificial neural network (ANN) integrated with genetic ...

Fluvial transport of suspended sediment and organic carbon during flood events in a large agricultural catchment in southwest France. [PDF]

, 2011
Water draining from a large agricultural catchment of 1 110 km2 in southwest France was sampled over an 18-month period to determine the temporal variability in suspended sediment (SS) and dissolved (DOC) and particulate organic carbon (POC) transport ...

Recent changes of suspended sediment yields in the Upper Yangtze River and its headwater tributaries [PDF]

Proceedings of the International Association of Hydrological Sciences, 2015
Suspended sediment yields in the Upper Yangtze River and its four headwater tributaries (i.e. Jinsha, Min, Jialing and Wu) have declined significantly during recent decades.

An Integrated Vegetated Treatment System for Mitigating Imidacloprid and Permethrin in Agricultural Irrigation Runoff

Toxics, 2021
Pyrethroid and neonicotinoid pesticides control an array of insect pests in leafy greens, but there are concerns about the off-site movement and potential water quality impacts of these chemicals.
