Book Description
This publication comes with computer software and presents a comprehensive simulation model designed to predict the hydrologic response, including potential for surface and groundwater contamination, of alternative crop-management systems. It simulates crop development and the movement of water, nutrients and pesticides over and through the root zone for a representative unit area of an agricultural field over multiple years. The model allows simulation of a wide spectrum of management practices and scenarios with special features such as the rapid transport of surface-applied chemicals through macropores to deeper depths and the preferential transport of chemicals within the soil matrix via mobile-immobile zones. The transfer of surface-applied chemicals (pesticides in particular) to runoff water is also an important component.

Book Description
Complex mathematical and computational models are used in all areas of society and technology and yet model based science is increasingly contested or refuted, especially when models are applied to controversial themes in domains such as health, the environment or the economy. More stringent standards of proofs are demanded from model-based numbers, especially when these numbers represent potential financial losses, threats to human health or the state of the environment. Quantitative sensitivity analysis is generally agreed to be one such standard. Mathematical models are good at mapping assumptions into inferences. A modeller makes assumptions about laws pertaining to the system, about its status and a plethora of other, often arcane, system variables and internal model settings. To what extent can we rely on the model-based inference when most of these assumptions are fraught with uncertainties? Global Sensitivity Analysis offers an accessible treatment of such problems via quantitative sensitivity analysis, beginning with the first principles and guiding the reader through the full range of recommended practices with a rich set of solved exercises. The text explains the motivation for sensitivity analysis, reviews the required statistical concepts, and provides a guide to potential applications. The book: Provides a self-contained treatment of the subject, allowing readers to learn and practice global sensitivity analysis without further materials. Presents ways to frame the analysis, interpret its results, and avoid potential pitfalls. Features numerous exercises and solved problems to help illustrate the applications. Is authored by leading sensitivity analysis practitioners, combining a range of disciplinary backgrounds. Postgraduate students and practitioners in a wide range of subjects, including statistics, mathematics, engineering, physics, chemistry, environmental sciences, biology, toxicology, actuarial sciences, and econometrics will find much of use here. This book will prove equally valuable to engineers working on risk analysis and to financial analysts concerned with pricing and hedging.

Book Description
Drought is one of the most important drivers of yield loss in maize (Zea Mays L.). Maize breeders have worked to improve yield potential under limited irrigation conditions over the past 60 years. A better understanding of the factors underlying yield loss under drought and of the methods to improve stress imposition are required to improve the efficiency of selection. Management of controlled stress requires a detailed understanding of the site's characteristics in order to reduce the deleterious effect of environmental variation due to field variability. In this research, relations between apparent electroconductivity and plant traits frequently used for maize drought screening were established using data collected during three years in one field in the central valley of California. Spatial and temporal variability in grain yield were described using clustering of standardized data and generating a series of field maps for three years of field testing. Soil physical properties were used to estimate hydraulic characteristics of the soil such as saturation, saturated soil hydraulic conductivity, field capacity, and wilting point, and these estimates were correlated to apparent soil electroconductivity for this specific field. In addition, models were developed to explore the potential of using soil electroconductivity as predictor variable for soil texture characteristics. Finally, management zones were created using integrated clusters calculated from grain yield across the three years as the response varaible and site specific electroconductivity data as predictor variables. The results indicate that soil apparent electroconductivity can be a useful and relatively inexpensive tool to assess field variability and define management zones describing site specific potential for drought stress studies.
