Civil Engineering and Environmental Systems is devoted to the advancement of systems thinking and systems techniques throughout systems engineering, environmental engineering decision-making, and engineering management. We do this by publishing the practical applications and developments of "hard" and "soft" systems techniques and thinking.Submissions that allow for better analysis of civil engineering and environmental systems might look at:-Civil Engineering optimization-Risk assessment in engineering-Civil engineering decision analysis-System identification in engineering-Civil engineering numerical simulation-Uncertainty modelling in engineering-Qualitative modelling of complex engineering systems
