This textbook covers tools and applications in civil engineering systems, dealing with a range of challenges that civil engineers will typically encounter during their professional lives, ranging from municipal planning and infrastructure management to transportation analysis. Many real-life examples are utilized. Students will learn to understand a system, conceptualize a model, analyse it and make decisions or draw conclusions, just as practising engineers do. Instructors can choose to cover some of the material from the foundation chapters on mathematics and statistics or directly concentrate on the tools and applications.
