The
concept of bypass flow through macropores and preferred routes and the fact that they will
permit rapid movement of water and chemicals dates back to Schumacher (1864) who stated
that, "the permeability of a soil during infiltration is mainly controlled by big
pores, in which water is not held under the influence of capillary forces." Intense
studies in the last few decades have also indicated that preferential flow mechanism is
the most sig-nificant flow process influencing the pollution potential and trans-port of a
given chemical in the porous media. To this effect, scientists and engineers have devised
measurement and modeling strategies in order to characterize and quantify the role of
preferential flow processes in water and pollutant transport through porous media.
However, heterogeneity of soil media, diverse management practices, and variable
climatologic conditions all of which affect the magni-tude of preferential flow, have
created a great challenge for all involved. Lack of proper models and feasible measurement
tech-niques for quantifying preferential movement of chemicals have made the managers and
environmental regulators uneasy as well. This symposium will focus on topics ranging from significance and role of preferential flow on water quality to measurement and model-ing of preferential flow including management effects and affects of physical and chemical processes. On behalf of the organizing committee members, it is a great plea-sure for me to extend to you a warm invitation to attend the 2nd International Preferential Flow Symposium in Honolulu, Hawaii. Please encourage your friends and colleagues to attend too. Also, please note that this symposium will be held concurrently with the Soil Erosion Research Symposium and you will have a great chance to interact with many more colleagues dealing with environmental issues.
