Practical Probability and Reliability Methods for Civil and Environmental Engineering sets out useful probabilistic methods and their efficient implementations across civil engineering, including transportation and traffic, hydrosystems, environmental, geotechnical and structural engineering. The book aims to overcome conceptual and implementation hurdles surrounding probability methods for civil and environmental engineers and serves as a textbook for upper-level undergraduates and beginning graduate students. It makes use of Microsoft Excel's versatile constrained optimization Solver tool, using some simple VBA codes, including FORM, SORM, system reliability, importance sampling, direct MCS, and response surface techniques. Solutions can be downloaded free for hands-on appreciation and deeper understanding. PowerPoint slides based on the book are available for adopting course instructors. The book pairs well with the author's Reliability-Based Design in Soil and Rock Engineering (CRC Press, 2021).
