Available in PDF, EPUB and Kindle. Book excerpt: Despite advances in modeling, such as graphical user interfaces, the use of GIS layers, and databases for developing input files, the approaches to modeling phosphorus (P) have not changed since their initial development in the 1980s. Current understanding of P processes has evolved and this new information needs to be incorporated into the current
Book Synopsis Watershed Management for Potable Water Supply by : National Research Council
Download or read book Watershed Management for Potable Water Supply written by National Research Council and published by National Academies Press. This book was released on 2000-02-17 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1997, New York City adopted a mammoth watershed agreement to protect its drinking water and avoid filtration of its large upstate surface water supply. Shortly thereafter, the NRC began an analysis of the agreement's scientific validity. The resulting book finds New York City's watershed agreement to be a good template for proactive watershed management that, if properly implemented, will maintain high water quality. However, it cautions that the agreement is not a guarantee of permanent filtration avoidance because of changing regulations, uncertainties regarding pollution sources, advances in treatment technologies, and natural variations in watershed conditions. The book recommends that New York City place its highest priority on pathogenic microorganisms in the watershed and direct its resources toward improving methods for detecting pathogens, understanding pathogen transport and fate, and demonstrating that best management practices will remove pathogens. Other recommendations, which are broadly applicable to surface water supplies across the country, target buffer zones, stormwater management, water quality monitoring, and effluent trading.

This book was released on 2015 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: An important cause of freshwater contamination in the United States, soluble reactive phosphorus (SRP) loss from agriculture often occurs when overland runoff transports phosphorus (P) from manures and fertilizers to receiving waters. Because of the importance of overland runoff in transporting P, models that allow us to pinpoint the location and timing of overland runoff are an important tool for reducing SRP transport in overland runoff. We created a simple regional model that allows us to predict the timing and location of runoff in the northeastern United States. In addition, we conducted soil box experiments which indicate that SRP concentrations decline rapidly over time after manure fertilization, and this decline in P availability is affected by temperature. We developed an SRP model which predicts the SRP concentration after manure application, which, combined with the spatially explicit watershed model, allows for prediction of SRP loss from agriculture under a variety of manure timing scenarios. We find that in a 326 km2 watershed where farmers apply P to match crop needs, simply changing the timing of manure application to avoid periods of runoff have the potential to reduce manure-derived SRP in runoff by up to 40%. iii.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Increasing evidence of phosphorus (P) contamination of surface water has precipitated numerous research efforts, both in government agencies and at academic institutions. These efforts have been overwhelmingly committed to characterizing this problem from a biophysical perspective, through fields such as limnology, aquatic ecology, soil science and agronomy---and have yielded great results. In many watersheds, particularly in the Eastern Cornbelt, phosphorus loading comes largely from row-crop agriculture. As a non-point source, phosphorus transport from individual agricultural operations cannot be directly monitored or regulated. Consequently, it behooves those interested in improving water quality to couple biophysical research with research devoted to understanding what social variables are animating the land management decisions ultimately responsible for contamination. Given this need, the objectives of this research were twofold. The first objective of this research was to characterize the current phosphorus risk assessment information available to farmers, in light of the emerging problem of soluble P. The second objective was to assess farmers' understanding of phosphorus management, which includes transport, fate and the risks associated with nutrient loss. Twenty-three farmers participated in in-depth interviews where they were asked questions pertaining to phosphorus management. Results were then coded and mapped onto the expert influence diagram illustrating key knowledge strengths and weaknesses. Individual farmers were assigned a knowledge score based on concept recognition. Knowledge scores were then correlated to self-reported risk perception measures. The results indicate that farmers are thoroughly versed in the transport of P via direct soil loss, but have a much lower understanding of the transport of soluble P via surface runoff. Overall, risk perception is positively correlated to knowledge with risk perception levels relatively high. The risk perception results suggest that farmers are well positioned to receive and process a risk communication effort designed to address knowledge deficiencies specific to soluble P mitigation behavior.
Book Synopsis Sources, Fate, and Transport of Nitrogen and Phosphorus in the Chesapeake Bay Watershed by : Scott W. Ator
Download or read book Sources, Fate, and Transport of Nitrogen and Phosphorus in the Chesapeake Bay Watershed written by Scott W. Ator and published by Geological Survey (USGS). This book was released on 2011 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spatially Referenced Regression on Watershed Attributes (SPARROW) was used to provide empirical estimates of the sources, fate, and transport of total nitrogen (TN) and total phosphorus (TP) in the Chesapeake Bay watershed, and the mean annual TN and TP flux to the bay and in each of 80,579 nontidal tributary stream reaches. Restoration efforts in recent decades have been insufficient to meet established standards for water quality and ecological conditions in Chesapeake Bay. The bay watershed includes 166,000 square kilometers of mixed land uses, multiple nutrient sources, and variable hydrogeologic, soil, and weather conditions, and bay restoration is complicated by the multitude of nutrient sources and complex interacting factors affecting the occurrence, fate, and transport of nitrogen and phosphorus from source areas to streams and the estuary. Effective and efficient nutrient management at the regional scale in support of Chesapeake Bay restoration requires a comprehensive understanding of the sources, fate, and transport of nitrogen and phosphorus in the watershed, which is only available through regional models. The current models, Chesapeake Bay nutrient SPARROW models, version 4 (CBTN_v4 and CBTP_v4), were constructed at a finer spatial resolution than previous SPARROW models for the Chesapeake Bay watershed (versions 1, 2, and 3), and include an updated timeframe and modified sources and other explantory terms.

This book was released on 2020-12-04 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: New York City's municipal water supply system provides about 1 billion gallons of drinking water a day to over 8.5 million people in New York City and about 1 million people living in nearby Westchester, Putnam, Ulster, and Orange counties. The combined water supply system includes 19 reservoirs and three controlled lakes with a total storage capacity of approximately 580 billion gallons. The city's Watershed Protection Program is intended to maintain and enhance the high quality of these surface water sources. Review of the New York City Watershed Protection Program assesses the efficacy and future of New York City's watershed management activities. The report identifies program areas that may require future change or action, including continued efforts to address turbidity and responding to changes in reservoir water quality as a result of climate change.
