The integrator delay zero (IDZ) model presented by Litrico and Fromion is a simple way to model a canal for control purposes that extends the classical integrator delay model. This analytical model gives a very good frequency domain approximation of the Saint-Venant transfer matrix for a pool possibly in backwater conditions. The present paper shows how this model can be used to model an irriga...

Transportation has been one of the essential areas within civil engineering since its early days. In commemoration of the 150th anniversary of ASCE, this paper presents a review of developments in research, education, and practice in transportation engineering. The review is based primarily on the issues of the Journal of Transportation Engineering over the past several decades. Main topics inc...

1. Many friends and colleagues have contributed to our research in various ways throughout time. In particular we acknowledge our discussant, Dr. A. Lago, President of ASCE; Mr. J. F. Alonso, also of ASCE, who facilitated us some data; Dr. C. Mesa-Lago, of U. Pittsburgh; Mr. S. Lippe, of Radio Marti; Dr. J. Clark, of Miami Dade CC.; Messrs. T. Bonn and L. Styles, of SUNY-Cortland, who facilitat...

ASCE has committed the profession to sustainability for at least a decade. The implied educational imperative is for a broader and deeper preparation of new engineers, and at the same time, of the practicing profession. The ASCE committee working on the second edition of the Civil Engineering Body of Knowledge has embraced sustainability as an independent technical outcome; and has set out spec...
