This book was released on 2005 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of The Discovery Museums (TDM) Low Impact Development (LID) Design and Monitoring report (Master of Engineering Group Project) for the town of Acton, the effectiveness of low impact development technologies at improving the quality of stormwater runoff from TDMs parking lot was evaluated. Several Best Management Practices (BMPs) and LID technologies were assessed to determine which devices would be most suitable for the site. The P8 Urban Catchment Model was chosen to model phosphorus concentrations in stormwater runoff before and after the implementation of LID. The results were then assessed to determine whether or not these technologies significantly improve the runoff water quality. In this thesis, the analysis is extended to assess the improvement in phosphorus concentrations if rain gardens are implemented on a fraction of residential areas in the Nashoba Brook watershed. The effectiveness of a rain garden at improving the phosphorus concentrations in runoff was evaluated by modeling the device in P8. Both the TDM site analysis and the Nashoba Brook hypothetical analysis yielded results with significant reduction in total phosphorus loading. These results should encourage further research on the widespread use of LID.

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
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 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: This book enhances knowledge on Impounded Water Bodies (IWB) systems of the interested parties. They include academicians, scholars, scientist, researchers, engineers, undergraduate and postgraduate students. Specifically this book is valuable for everyone involved in water, hydrology, environment, civil engineering and other related disciplines. This book emphasized modelling and simulation of IWB particularly; Reservoir and Detention Pond, in relation to the two major hydrological problems; Flood and Water Pollution. The knowledge presented is useful for hydrological systems real phenomenon replication and prediction. This book also provides IWB general overview, in terms of the preliminary and state of the art analysis which may trigger the interest for further research and investigations. The IWB related factors were integrated to provide the quantitative framework, alternative approaches and valuable outcomes that lead to worthy policy establishment. This book covers topic related to nutrient (phosphorus) loadings estimation using the new version of Event-Based Stochastic Model in reservoir systems. The detention pond systems modelling using Analytical Probabilistic Models (APM) and the optimization of detention time using Particle Swarm Optimization (PSO) are elaborated. It is hoped that the book provides useful knowledge in pursuit of the IWB sustainable development.

Available in PDF, EPUB and Kindle. Book excerpt: "The ability of the NICA model to describe phosphate (PO4) adsorption to soil particles was tested using soils collected from agricultural fields in southern Quebec. The surface charge and PO4 adsorption capacity of these soils were measured. Results were used to estimate the NICA model parameters using a non-linear fitting function. The NICA model accurately described the surface charge of these soils and the PO4 adsorption processes." --

Book excerpt: The research work contained in this report concerns the transport of total phosphorus and orthophosphorus to Lake Erie. The various calculational techniques for analyzing data obtained from Lake Erie tributaries are presented. These calculations were developed to determine the source of the phosphorus and to quantify the input to the lake. The source and quantity of phosphorus devised for Lake Erie. The first section of this report presents the basic concepts, mass balances (that applied to the water and that applied to the phosphorus), and force relationships. The second section of this report concerns the quantification of total phosphorus input to Lake Erie river basins and shortline sources. A computational method called the Flow Interval Method was devised to permit the calculaion of total phosphorus influx without measuring the total phosphorus concentration for the entire year. Another important aspect of reducing total phosphorus influx from river basins is the understanding of the transport processes in rivers. The third section of this report concerns the transport of total phosphorus during storm events. The fourth section of this report presents the derivation of the necessary equations used to calculate the distance of the travel density function form measurements of the water flow rate and the total phosphorus concentrations at a point in the stream.
