Modeling event-based coupled hydrologic and mass transport in small urban watersheds
… several methodologies were developed. Discrete rainfall-runoff events data were collected at two similar urban watersheds for model calibration and verification. A mathematically and physically-based criterion was proposed to differentiate rainfall-runoff events between either mass-limited or …

Extracting value from patterns in routinely collected, high-frequency water quality data in rivers supplying drinking water treatment works
… testing of a rule-based approach for identifying rainfall-runoff events from sub-hourly flow data. This approach aims to provide a repeatable method for generating metrics for use in further analysis. The potential to unlock value in routinely collected, high-frequency, water quality data is …

Nutrient and Bacterial Transport From Agricultural Lands Fertlized With Different Animal Manures
… the loss of nutrients and bacterial transport in runoff from cropland treated with poultry litter, dairy manure and inorganic fertilizer according to the P requirements of the crop. Three simulated rainfall events were conducted 1, 2 and 35 days after planting of corn. Highest P and N …

Modeling the hydrologic and particulate loadings from paved urban surfaces
… non-colloidal particulate matter found in urban rainfall-runoff and urban snowmelt. Three forms of the power law model (PLM) were used to model particle number density. It was found that significant model error could be introduced into PLMs when the median diameter particle was used to estimate …

Rainfall-runoff control: variably saturated transport for an infiltration system controlling water quality and quantity
Rainfall-runoff impacted by anthropogenic activities transports significant quantities of particulate, aqueous and complexed constituents. These diffuse, unsteady and stochastic event-based loadings are unique challenges for water quality and quantity control. The design, water quality and quantity …

Soil moisture dynamics and soil moisture controlled runoff processes at different spatial scales : from observation to modelling
… moisture is a key state variable that controls runoff formation, infiltration and partitioning of radiation into latent and sensible heat. However, the experimental characterisation of near surface soil moisture patterns and their controls on runoff formation remains a challenge. This subject …

Hydrological and erosion responses to man-made and natural disturbances : insights from forested catchments in South-central Chile
… in turn intensifies surface erosion. Above a rainfall intensity of ~20 mm/h, which corresponds to <10% of all rainfall, THAs may generate runoff whereas below that threshold they remain sinks. The overall contribution of Hortonian runoff is thus secondary considering the local rainfall regime. …
