Novel sediment source fingerprinting quantifying erosion-induced total nitrogen and total phosphorus outputs from an intensive agricultural catchment, North China

Quantifying total suspended sediment export from the Burdekin River catchment using the loads regression estimator tool

[1] The loads regression estimator (LRE) was introduced by Wang et al. (2011) as an improved approach for quantifying the export of loads and the corresponding uncertainty from river systems, where data are limited. We extend this methodology and show how LRE can be used to analyze a 24 year record of total suspended sediment concentrations for the Burdekin River. For large catchments with high...

Modification of phosphorus export from an eastern USA catchment by fluvial sediment and phosphorus inputs

Phosphorus (P) export from agricultural catchments can accelerate freshwater eutrophication. Landscape-based remedial measures can reduce edge-of-field P losses. However, stream channel hydraulics and fluvial sediment properties can modify the forms and amounts of P exported by the time it reaches the catchment outlet. This study examines if land use, fluvial sediment properties, and storm flow...

Prediction of runoff and sediment from agricultural watersheds by a mathematical model. 3 sediment -bound and soluble phosphorus loadings.

A Catchment-Scale Model of Road Erosion and Sediment Delivery

Unsealed roads and tracks are potentially significant sources of diffuse pollutants, particularly sediment. Identifying critical diffuse pollutant sources and their transport potential can greatly improve catchment-scale water quality management. This study describes the application and ongoing development of a road erosion and sediment transport model in the Moruya-Deua and Tuross River catchm...

Development of Software Sensors for Determining Total Phosphorus and Total Nitrogen in Waters

Total nitrogen (TN) and total phosphorus (TP) concentrations are important parameters to assess the quality of water bodies and are used as criteria to regulate the water quality of the effluent from a wastewater treatment plant (WWTP) in Korea. Therefore, continuous monitoring of TN and TP using in situ instruments is conducted nationwide in Korea. However, most in situ instruments in the mark...
