dc.description.abstract The objectives of this study were two-fold. Firstly, to make in situ and associated laboratory measurements of soil physical properties (hydraulic conductivity, bulk density and the desorption water capacity relationship) which govern the storage and transmission of water solutions. Secondly, to characterize or represent these soil properties so that they may be applied in the nitrogen and water transport simulation program of D.R. Cameron et al. (Project 13). The wide variation in soil properties in the two watersheds meant that different field measurement methods were used in each watershed. It was assumed that the hydraulic conductivity was the major property controlling transmission of water and a number of attempts were made to measure this in both watersheds. In Watershed AG-1 the shrinking and cracking of the clay soil meant that cracks played an important role in the transmission of water and additional measurements were necessary. The water storage properties were measured in the laboratory.
