Applications of Soil Physics deals with the applications of soil physics and covers topics ranging from infiltration and surface runoff to groundwater drainage, evaporation from bare-surface soils, and uptake of soil moisture by plants. Water balance and energy balance in the field are also discussed, along with tillage and soil structure management. The development and extension of Penman's evaporation formula is also described. This book is comprised of 14 chapters and begins with a systematic description of the field-water cycle and its management, with emphasis on infiltration and runoff; redistribution and drainage; evaporation and transpiration; and irrigation and tillage. Subsequent chapters focus on transpiration from plant canopies; freezing phenomena in soils; scaling and similitude of soil-water phenomena; spatial variability of soil physical properties; and movement of solutes during infiltration into homogeneous soil. Concepts of soil-water availability to plants are considered, together with principles of irrigation management and the advantages and limitations of drip irrigation. This monograph is intended for upper-level undergraduate and graduate students of the environmental, engineering, and agronomic sciences.

This paper overviews the general features of computer program 'HEC-5, Simulation of Flood Control and Conservation Systems', with emphasis on the capabilities of the most recent release of HEC-5, Version 7.2, dated March 1991. HEC-5 can simulate the essential features and operation goals and constraints of simple or complex systems with simulation intervals ranging from minutes to one month. Single event flood analysis and period of record conservation analysis may be accomplished with the model. Flood control analysis includes balanced system operation for downstream damage centers with consideration of forecasted local flows and hydrologic routing. In addition, induced surcharge operation based on spillway gate regulation schedules can be simulated. Hydropower analysis may include run-of-river, peaking, and pumped storage plants as well as system power operation. Water supply simulation can include reservoir and downstream flow requirements in addition to divers ions and return flows. Water Quality analysis can include simulation of temperature, dissolved oxygen, up to three conservative and up to three nonconservative constituents.

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.
