Path and Multiple Regression Analyses of Phosphorus Sorption Capacity
Soil P saturation indices and P Langmuir adsorption maximum (S max ) are two environmental soil tests that provide valuable information for the proper management P in soils to avoid the
Nutrient retention in a point-source-enriched stream
Abstract The capacity of a 3rd-order Ozark Plateau stream (Arkansas, USA) to take up (or remove) nutrient inputs from a rural wastewater treatment plant (WWTP) was examined using nutrient spiraling
Evaluating nonpoint source critical source area contributions at the watershed scale.
TLDR
This research is a synthesis of CSA targeting studies performed in six Oklahoma priority watersheds from 2001 to 2007 to aid the Oklahoma Conservation Commission in the prioritized placement of subsidized conservation measures.
Influence of Buffers on Pesticide and Nutrient Runoff from Bermudagrass Turf
Buffer length (0, 2.4, and 4.9 m), mowing height (1.3 and 3.8 cm), and solid-tine aerification were evaluated to reduce pesticide and nutrient runoff from bermudagrass [Cynodon dactylon (L.) Pers.]
Evaluation of Runoff, Erosion, and Phosphorus Modeling System--SIMPLE
: The purpose of this study was to evaluate the performance of Spatially Integrated Models for Phosphorus Loading and Erosion (SIMPLE) in predicting runoff volume, sediment loss, and phosphorus
Water Treatment Residual to Reduce Nutrients in Surface Runoff from Agricultural Land
Application of animal manures in excessive amounts can result in surface runoff of nutrients and degradation of surface water. Best management practices that use chemical or by-products to sorb
Subsurface transport of phosphorus in riparian floodplains: influence of preferential flow paths.
TLDR
The potential for nutrient subsurface transport shown by this alluvial system has implications regarding management of similar riparian floodplain systems.
Two-phase Uncertainty Analysis: An Example Using the Universal Soil Loss Equation
Hydrologic and water quality (H/WQ) models are important tools for environmental assessment and management. Model simulations are often performed deterministically, which results in a single estimate
Limiting nutrient determination in lotic ecosystems using a quantitative nutrient enrichment periphytometer
: The decline of water quality in United States’ lotic ecosystems (streams and rivers) has been linked to nonpoint source nutrient loading (U.S. EPA, 1990). Determining limiting nutrients in streams
Statistical Procedure for Evaluating Hydrologic/Water Quality Models
Input parameters are used in hydrologic/water quality models to describe specific situations. These input parameters are never known with certainty. The models, although largely physically based, are
