The proceedings contain 30 papers covering a wide range of research areas that discuss the importance of water in semi-arid regions, with an emphasis on dam engineering. This information is vital for reliable, efficient, and economic construction and maintenance of geo-structures. Geotechnical engineers who specialize in dam, highway materials, and soil improvement will benefit from this book. The Geo Jordan 2004 Conference was held in Irbid, Jordan, on July 12-15, 2004. Topics include: improvement of soil properties using geosynthetics and chemical stabilization; use of TDR and other geophysical methods to detect pollutants in soils and to assess properties of embankments; modelling the constitutive behavior of soils and fluid flow through granular materials; case histories of design filters for dams; Monitoring and rehabilitation of dams; and embankments and geo-structures.
