Interpretive Summary: "Methods of Soil Analysis" is a standard reference book for laboratory and field analyses of soils. This book chapter was prepared for an updated edition of "Methods". The chapter discusses methods of analyzing solute transport experiments and determining solute transport parameters. Knowledge of solute fate and transport is needed to determine the impact of agricultural practices on soil and water quality. This work will benefit the many commercial, government, and university laboratories that rely on "Methods of Soil Analysis."

Technical Abstract: This book chapter discusses methods of analyzing solute transport data and describes procedures for estimating solute transport parameters. The chapter covers least-squares optimization and moment methods for estimating dispersion, velocity, and sorption parameters, including procedures applicable to non-uniform and transient flow conditions. Also covered are methods for determining solute travel-time probability density functions from concentration measurements and from Time Domain Reflectometry instrumentation. Additionally, a method is presented for estimating physical nonequilibrium parameters using a disk permeameter and multiple solutes.
