For phosphorus (P) transport from upland areas to surface water systems, the primary transport mechanism is typically considered to be surface runoff with subsurface transport assumed negligible. However, certain local conditions can lead to an environment where subsurface transport may be significant. The objective of this research was to determine the potential of subsurface transport of P along streams characterized by cherty or gravel subsoils, especially the impact of preferential flow… Expand
Preferential Flow Path Effects on Subsurface Contaminant Transport in Alluvial Floodplains
For strongly sorbing contaminants, transport from upland areas to surface water systems is typically considered to be due to surface runoff with subsurface transport assumed negligible. However,Expand
Impact of Preferential Flow Paths on Alluvial Groundwater Flow Patterns and Phosphorus Transport
While surface runoff is considered to be the primary transport mechanism for phosphorus (P), subsurface transport through coarse subsoil to gravel bed streams may be significant and represent aExpand
Comparison of subsurface and surface runoff phosphorus transport rates in alluvial floodplains
Abstract Phosphorus (P) loading to streams can occur by both surface runoff and subsurface transport, with subsurface P transport often assumed negligible. Groundwater P concentrations in alluvialExpand
For sorbing contaminants, transport from upland areas to surface water systems is typically considered to be due to surface runoff, with negligible input from subsurface transport assumed. However,Expand
Comparison of Subsurface and Surface Runoff Phosphorus Transport Capacities in Alluvial Floodplains
There have been numerous studies on phosphorus (P) contributions from surface runoff, but studies comparing the contribution of surface versus subsurface P are limited, as subsurface transport isExpand
Impact of Preferential Flow Paths on Stream and Alluvial Groundwater Interaction
A better understanding of stream-aquifer interactions is needed both for water policy and for quantifying its impact on stream chemistry and water quality. Assuming homogeneity in alluvial aquifersExpand
Impact of macropores and gravel outcrops on phosphorus leaching at the plot scale in silt loam soils
In response to increased nutrient loads in surface waters, scientists and engineers need to identify critical nutrient source areas and transport mechanisms within a catchment to protect beneficialExpand
Quantification and Heterogeneity of Infiltration and Transport in Alluvial Floodplains
In order to protect drinking water systems and aquatic ecosystems, all critical nutrient source areas and transport mechanisms need to be characterized. It is hypothesized that hydrologicExpand
Stage-dependent transient storage of phosphorus in alluvial floodplains
Models for contaminant transport in streams commonly idealize transient storage as a well mixed but immobile system. These transient storage models capture rapid (near-stream) hyporheic storage andExpand
Field Evidence of a Natural Capillary Barrier in a Gravel Alluvial Aquifer
Ozark streams commonly feature “composite” floodplains, in which the vadose zone consists of silt or silt loam soils (?1 m thick) overlying gravel subsoil. Previous work has shown that preferentialExpand


Subsurface Transport of Phosphorus in Riparian Floodplains: Tracer and Phosphorus Transport Experiments
The primary transport mechanism for phosphorus (P) movement from upland areas to surface water systems is typically surface runoff, with subsurface transport assumed negligible. However, certainExpand
Groundwater phosphate dynamics in a river riparian zone: effects of hydrologic flowpaths, lithology and redox chemistry
This study examines the influence of riparian zone hydrology, lithology and redox chemistry on groundwater phosphate dynamics. Patterns of soluble reactive phosphorus (SRP), dissolved oxygen (DO) andExpand

Lake Bysjön is a hypertrophic seepage lake, with groundwater as a main external source of phosphorus. Twelve groundwater samples from the vicinity of the lake were high in phosphate (0.4 to 11 mgExpand
Surface and subsurface phosphorus losses from fertilized pasture systems in Ohio.
Applying P fertilizer to pastures in response to soil tests should keep TDRP concentrations in subsurface flow at environmentally acceptable levels and management to reduce runoff and avoidance of P fertilizer application when runoff producing rainfall is anticipated in the next few days will help reduce the surface losses of P.

Agricultural Phosphorus and Eutrophication: A Symposium Overview
Phosphorus in runoff from agricultural land is an important component of nonpoint-source pollution and can accelerate eutrophication of lakes and streams. Long-term land application of P asExpand

Abstract. Reducing non-point source phosphorus (P) loss to drinking water reservoirs is a main concern for New York City watershed planners, and modeling of P transport can assist in the evaluationExpand
Comparison of instream methods for measuring hydraulic conductivity in sandy streambeds.
Streambed hydraulic conductivity values were determined at seven stream transects in the Platte River Basin in Nebraska using different instream measurement techniques, indicating that selection of a method for measuring streambed K needs to consider the vertical location of the sediments that are most likely to limit the rate of ground water/surface water interaction.
