Advances in Irrigation, Volume 4 covers articles on the development and management of irrigation. The book presents articles on the improved method for distributing water in furrows, termed cablegation; the analysis of drip irrigation design based on the criterion of statistical uniformity; and the spatial distribution of water in sprinkling-irrigation systems. The text also includes articles on the critical evaluation of crop yields as influenced by irrigation uniformity; the concept of evapotranspiration from the scale of a field to the scale of an entire region; as well as the drainage of irrigated lands under sequential water application. Articles on the comparison of several models for the purpose of appraising the effect of irrigation on wheat and barley yields and on the economics of kiwifruit production under irrigation in New Zealand are also encompassed. The book concludes with an article about the modification and testing of a model simulating root and shoot growth as related to soil water dynamics. Agriculturists, agricultural engineers, and hydrologists will find the book invaluable.
