Except for calculus, all necessary background is included.  

An integrated coverage of probability, statistics, Monte Carlo simulation, inferential statistics, design of experiments, systems reliability, fitting random data to models, analysis of variance, stochastic processes, and stochastic differential equations for engineers and scientists. The author for first time presents an introduction to the broad field of applied engineering uncertainty analysis in one comprehensive, friendly, coverage.Each concept is illustrated with several examples of relevance in engineering applications (no cards, colored balls, or dice): 478 pages; 177 solved examples; 147 proposed problems; 174 illustrations, 69 short computer programs; and 51 data and statistical tables. Clear presentation of concepts. Practical engineering examples. No cards, no dice, no colored balls. Prepares the reader for today's problems in engineering analysis, modeling, and design under uncertainty. This edition includes new research advances in nonlinear stochastic equations; simple methods to solve and graph boundary-value problems in several dimensions. Integrated treatment of probability, statistics, and stochastic modeling. Includes numerical (Monte Carlo) simulations and analytical modeling. Intuitive and graphical introduction to stochastic processes. Practical introduction to applied stochastic differential equations.

An integrated coverage of the subjects of surface, subsurface, and contaminant hydrology. The author presents the fundamental concepts of physical and contaminant hydrology of watersheds, rivers, lakes, soils, and aquifers in an easy and accessible manner to the environmental professional. Prepares the reader to analyze today's environmental problems. Many practical examples and solved problems illustrate the concepts. This edition includes clear presentation of concepts, consistent notation, 124 solved examples, 187 proposed problems, 152 illustrations, 71 tables, 46 short computer programs in MAPLE, answers to problems, extensive bibliography. State of the art research on groundwater and contaminant transport modeling is explained in a clear fashion. Recent research developments in nonlinear hydrologic science and simulation are included in this new edition. New solutions of nonlinear infiltration are presented with simple numerical applications. New developments in analytical decomposition are presented as simple and practical means to complex nonlinear hydrologic problems, such as regional groundwater flow modeling in homogeneous or heterogeneous media, regular or irregularly-shaped domains, steady or transient problems, multiple pumping wells, and nonlinear flow. For contaminant transport, new applications to the simulation of nonlinear decay, nonlinear sorption, and unsaturated-saturated zones contaminant propagation are presented along with simple programs.
