A year has passed since Eshel Bresler, my good friend and colleague, and a member of the editorial board of the Advanced Series in Agricultural Sciences, died suddenly while on a visit to the Chinese Academy of Sciences in Beijing. We had worked together for almost 30 years at the Institute of Soils and Water, ARO, The Volcani Center at Bet Dagan. At the very beginning of our scientific careers we cooperated directly and as a result one of our first publications was coauthored (Soil Sci. 101:205-209, 1966). Thereafter, our specific research interests diver sified, but we continued to work together, with similar approaches to research, and to strive towards the development of Israel soil science and its integration into general worldwide scientific progress. I don't need to emphasize Eshel's contribution to the understan ding of the processes governing water flow and solute transport pro cesses in soils and unsaturated zones. The contributions to this Volume by such a body of outstanding scientists shows the apprecia tion of the international scientific community to his research achievements.

Klappentext

"Water Flow and Solute Transport in Soils" reflects the main trends of contemporary research in this field and its applications. The contributions fall into three main areas: - The stochastic modeling of solute transport through he- terogeneous soil in the upper layer of the unsaturated zone. - The more traditional scope of analysis of flow through homogeneous or layered formations. - The applications like new devices for field measurements, calculation of solute movement through a soil cover, and the use of geo-statistical methods to quantify solute concentrations in spatially variable soils.
