Hydrology of Swelling Soils drainage and reclamation of swelling clays in flat landscapes. The paper reviews recent progress in the theory of water equilibrium and movement in swelling soils, and emphasizes that neglect of the fact of swelling may lead to serious errors of interpretation.

Salinity and the Hydrologic CycleThe hydrologic cycle, as a concept to allow orderly description of the ways in which precipitation on the land surface is partitioned between evaporation, run-off and other lesser consumption, usually exists in a natural steady state. If not, then at least, natural perturbations have a time scale of the order of thousands of years.

A Survey of the Principles of Metallic Corrosion and its Control in Saline WatersAn outline of the theory of corrosion processes is presented, using pH-potential diagrams to summarize theoretical and experimental data relating to corrosion; the pitting corrosion of iron in chloride-containing waters is treated in some detail.

Transport of Salts in Unsaturated and Saturated SoilsIn almost all conditions in the field, transport of soluble salts in soils results from movement (convection) of the soil solution as a whole, and molecular diffusion within the soil solution.

Economic and Social Aspects of Saline Water Use and ManagementSalinity problems resulting from high salinities in streams and in shallow watertables arise frequently from the clearing of forests and from irrigation. The major areas affected are the River Murray Valley and the south-western parts of Western Australia and Victoria.
