Book excerpt: Excess nutrient loads have been recognized to be the major cause of serious water quality problems recently encountered in the North Carolina estuaries and coastal waters. There has been a particular concern in coastal watersheds because agricultural and forested lands are located in close proximity to recreational and environmentally sensitive waters. The key to nutrient management at the watershed scale is the understanding and quantification of the fate of nutrients at the field scale and after they enter the aquatic environment. There is no accepted method to describe and predict fate of nutrients in canals and streams. The purpose of this research was to investigate the magnitude of the effects of in-stream processes in agricultural canals of the lower coastal plain and to propose a modeling approach for quantifying nitrogen transformations in such canals. This was accomplished in four steps. The first step was an extensive review of the literature on nitrogen retention in agricultural streams. Nitrogen removal rates in most agricultural canals and streams vary between 50 and 800 mg N/m2/d, with mass transfer coefficient varying between 0.01 and 0.10 m/d. The magnitude of nitrogen retention in streams and canals of agricultural watersheds has been reported to vary between less than 5% to more the 60% of the gross load. In the second step, the effects of biogeochemical processes on chemical and nutrient loads was evaluated in a 1125-m long agricultural canal reach of the lower coastal plain near the town of Plymouth, NC. Chemical and nutrient loads at both ends of the reach were measured by continuous measurement of flow and concentrations. Flow measurements were made using trapezoidal flumes in which flow velocity and depth was continuously measured and recorded with velocity meters. Nutrient concentrations were measured on water samples taken both manually and automatically at strategic times along the hydrographs so that linear interpolation between two c.

Book Synopsis Spatial Analysis and Modeling in Geographical Transformation Process by : Yuji Murayama
Download or read book Spatial Analysis and Modeling in Geographical Transformation Process written by Yuji Murayama and published by Springer Science & Business Media. This book was released on 2011-02-26 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Currently, spatial analysis is becoming more important than ever because enormous volumes of spatial data are available from different sources, such as GPS, Remote Sensing, and others. This book deals with spatial analysis and modelling. It provides a comprehensive discussion of spatial analysis, methods, and approaches related to human settlements and associated environment. Key contributions with empirical case studies from Iran, Philippines, Vietnam, Thailand, Nepal, and Japan that apply spatial analysis including autocorrelation, fuzzy, voronoi, cellular automata, analytic hierarchy process, artificial neural network, spatial metrics, spatial statistics, regression, and remote sensing mapping techniques are compiled comprehensively. The core value of this book is a wide variety of results with state of the art discussion including empirical case studies. It provides a milestone reference to students, researchers, planners, and other practitioners dealing the spatial problems on urban and regional issues. We are pleased to announce that this book has been presented with the 2011 publishing award from the GIS Association of Japan. We would like to congratulate the authors!
