Download PDF , 2. These hydraulic properties are key parameters in any quantitative description of water flow into and through the unsaturated zone of soils. The program uses the parametric models of. A brief review is also given of the nonlinear least-squares parameter optimization method used for estimating the unknown coefficients in the hydraulic models.

The RETC program may be used to predict the hydraulic conductivity from observed soil water retention data assuming that one observed conductivity value not necessarily at saturation is available. The program also permits one to fit analytical functions simultaneously to observed water retention and hydraulic conductivity data. Every two years, industry leaders and practitioners from around the world gather at the Rapid Excavation and Tunneling Conference RETC , the authoritative program for the tunneling profession, to learn about the most recent advances and breakthroughs in this unique field.

This comprehensive conference helps practicing professionals keep up with the ever changing and growing tunneling industry. Stay on top of new trends and technologies as well as innovative concepts, new equipment, materials, management, financing, and design challenges.

Welcome to RETC Discover why this is THE can't miss conference of It offers the unique opportunity for clients, contractors, and engineers to share ideas, lessons learned, and technical advancements across the industry. Bill Mariucci. Team Leader, Kiewit infrastructure Co.
