Digital Soil Mapping Bridging Research, Environmental Application, and Operation by Janis L Boettinger( )

1 edition published in 2010 in English and held by 10 WorldCat member libraries worldwide

Digital Soil Mapping is the creation and the population of a geographically referenced soil database. It is generated at a given resolution by using field and laboratory observation methods coupled with environmental data through quantitative relationships. Digital soil mapping is advancing on different fronts at different rates all across the world. This book presents the state-of-the art and explores strategies for bridging research, production, and environmental application of digital soil mapping.It includes examples from North America, South America, Europe, Asia, and Australia. The chapters address the following topics: - exploring new environmental covariates and sampling schemes - using integrated sensors to infer soil properties or status - innovative inference systems predicting soil classes, properties, and estimating their uncertainties - using digital soil mapping and techniques for soil assessment and environmental application - evaluating and using legacy soil data - protocol and capacity building for making digital soil mapping operational around the globe. Key themes: soil science --digital soil mapping - -soil survey and inventory - -soil information -geographic information systems Janis Boettinger is Professor of soil science at Utah State University, engaged in digital soil mapping research and outreach. Alfred E. Hartemink coordinates GlobalSoilMap.net from ISRIC - World Soil Information in The Netherlands. David Howell, Amanda Moore, and Suzann Kienast-Brown are digital soil mapping practitioners in the USA Soil Survey Program

A Numerical Study of Rain-Induced Surface Gravity Wave Attenuation by David W Howell( Book )

2 editions published in 1989 in English and held by 2 WorldCat member libraries worldwide

Strong rain-induced mixing in a thin surface layer is numerically shown to greatly increase surface gravity wave attenuation. This case study uses a single wavelength (2.8 m) together with two mixed layer depths (10 and 20 cm). The rain induced mixing is simulated by varying kinematic viscosity within the mixed layer from 0.000001 to 0.01 sq m per sec, molecular to strong turbulent mixing, respectively. The results indicate that surface gravity wave attenuation in the presence of a thin rain induced mixed layer can increase by a factor of up to 6000 times the attenuation rate due to molecular viscosity alone. This indicates that rain need only mix the top 10-20 cm surface layer to effectively dampen short surface gravity waves

=A transistor amplifier with 500-mc bandwidth by David W Howell( Book )

2 editions published in 1964 in English and held by 2 WorldCat member libraries worldwide

The design, construction, and evaluation of a lowpass transistor amplifier having 50-db insertion power gain and 500-Mc bandwidth are discussed. The amplifier, useful for i-f, rf, or fast-pulse amplification, consists of seven common-emitter stages, each having collectorto-base feedback. A generalized design procedure is given which should be useful for the con struction of other lowpass amplifiers having bandwidths of 500 Mc or greater. (Author)
