Parameter uncertainty in nonpoint source pollution modeling
… inherently non-deterministic nature of inputs in nonpoint source (NPS) pollution modeling and the lack of information in many cases results in considerable uncertainty in model input parameters, and therefore, model outputs. Uncertainty in input parameters has important implications for model use …

Nonpoint source pollution modeling of an agricultural watershed within a geographic information system
… the many strides made in the past two decades, nonpoint source (NPS) pollution continues to be an important environment management and water quality management problem. For the most part, analysis of NPS pollution in watersheds has depended on the use of lumped mathematical models to identify …

Modeling Fate and Transport of Nitrogen and Phosphorus in Crop Fields Under Tropical Conditions
Modeling is a very important tool for developing nonpoint source (NPS) pollution control plans. Current NPS models were developed for temperate conditions and, thus, do not appropriately represent tropical conditions. The objective of this research was to develop or adapt a nonpoint source …

Sediment Delivery from Reopened Forest Roads at Stream Crossings in the Virginia Piedmont Physiographic Region, USA
Efforts to control surface runoff and erosion from forest roads at stream crossings are critical for the protection of aquatic ecosystems in forests. In this research, annual and event-based sediment delivery rates were estimated for reopened legacy roads at forest stream crossings in the Virginia …
