Rainfall simulation experiments are widely used to study erosion and contaminant transport in overland flow. We investigated the use of two rainfall simulators designed to rain on 2-m-long (2-m2) and 10.7-m-long (32.6-m2) plots to estimate overland flow and phosphorus (P) transport in comparison with watershed-scale data. Simulated rainfall (75 mm h(-1)) generated more overland flow from 2-m-long (20 L m2) than from 10.7-m-long (10 L m2) plots established in grass, no-till corn (Zea mays L…

Small-scale, high-intensity rainfall simulation under-estimates natural runoff P concentrations from pastures on hill-slopes

Rainfall simulation is a widely used technique for studying the processes, and quantifying the mobilisation, of phosphorus (P) from soil/pasture systems into surface runoff. There are conflicting

Hydrology of small field plots used to study phosphorus runoff under simulated rainfall.

This study highlights the need for care in interpreting findings from generalized protocols that favor infiltration-excess runoff mechanisms, as natural runoff from the somewhat poorly drained soil is largely under wet antecedent conditions.

Evaluation of phosphorus transport in surface runoff from packed soil boxes.

This study reveals the practical, but limited, comparability of field plot and soil box data, highlighting soil and sediment buffering in unamended soils and manure WEP in amended soils as dominant controls of DRP transport.

Rainfall simulation underestimates runoff phosphorus concentrations from dairy pastures

Concentrations of phosphorus (P) in runoff from intensively managed pastures such as those used for dairying are high. Soil P has a large influence on runoff P concentrations. The most common


ABSTRACT: A curve number based model, Soil and Water Assessment Tool (SWAT), and a physically based model, Soil Moisture Distribution and Routing (SMDR), were applied in a headwater watershed in

Effect of Overland Flow Rate on Nutrient Transport from Land Application Areas

Little information is currently available concerning the effects of varying flow rate on nutrient transport by overland flow. The objective of this study was to measure the effects of overland flow

Using simulated rainfall to evaluate field and indoor surface runoff phosphorus relationships.

Evidence is provided that indoor runoff can adequately predict TP(<0.45) concentration in field surface runoff for select soils.

Scale-of-measurement effects on phosphorus in runoff from cropland

Phosphorus (P) risk loss assessment tools such as P indices are usually developed from small-plot scale data showing the relationships between various site and management variables and runoff P

Nutrient Transport as Affected by Rate of Overland Flow

Little information is currently available concerning the effects of varying flow rate on nutrient transport by overland flow. The objective of this study was to measure the effects of overland flow

Effect of plot scale and an upslope phosphorus source on phosphorus loss in overland flow

Abstract. Phosphorus (P) in overland flow is mediated by soil P, added P, erosion, and hydrological processes and their interaction as affected by landscape position and length of flow. We

Phosphorus export from an agricultural watershed: linking source and transport mechanisms.

This study shows that erosion, soil P concentration, and channel sediment P sorption properties influence streamflow dissolved reactive phosphorus (DRP) and TP.

A Portable Rainfall Simulator for Plot-Scale Runoff Studies

Rainfall simulators have a long history of successful use in both laboratory and field investigations. Many plot–scale simulators, however, have been difficult to operate and transport in the field,

Dynamics of stormflow generation—A hillslope‐scale field study in east‐central Pennsylvania, USA

A 40 m × 20 m mowed, grass hillslope adjacent to a headwater stream within a 26‐ha watershed in east‐central Pennsylvania, USA, was instrumented to identify and map the extent and dynamics of surface

Nitrate-Nitrogen, Soluble, and Bioavailable Phosphorus Runoff from Simulated Rainfall After Fertilizer Application

Runoff from crop land can enhance eutrophication of fresh water and hypoxia in sea water. We simulated rain at 25 mm hr ' for 2 hr, 8 d prior and 1, 14, 29, 49 and 108 d after fertilization and

Nonpoint-source pollution of surface water by the transport of sediment, N, and P in agricultural runoff is one of the nation's major water quality concerns. Consequently, concentrations and amounts

ABSTRACT: Modeling phosphorus (P) loss from agricultural watersheds is key to quantifying the long term water quality benefits of alternative best management practices. Scientists engaged in this

The adsorption of soluble P by surface soil and suspended sediment material during transport in surface runoff under field and simulated laborato ry conditions was investigated. The soluble P
