Land and Stream Salinity is a compilation of papers that review the state and knowledge of processes involved in land and stream salinity, and that consider its application in different environments. This book also identifies gaps in research and development, and it designates the priorities that could significantly benefit salinity control. In addition, it identifies alternative strategies of land and water management for salinity control and determines techniques for evaluating quantitatively the alternative strategies. Furthermore, this book focuses on salinity problems in south Western Australia. After discussing the history and effects of salinity in Western Australia, the book considers the influence of plant communities on the hydrology of catchments, and it discusses evapotranspiration rates from wet and dry foliage and soil water deficit. This is followed by the transport of salts in soils and subsoils; the residence times of water and solutes within and below the root zone and saturated zone; analyses of solute distributions in deeply weathered soils; and the transport of salts in catchments and soils. This book also includes chapters on the saline seed development and control in the North American Great Plains, and the terrain, groundwater and secondary salinity in Victoria, Australia. It also presents the hydrologic model, the solute-transport models and their role in the analysis of groundwater, and the hydrosalinity models. The last chapters focus on different kinds of management for salinity control.
