Design and Operation of Farm Irrigation Systems


Book Description

"This edition provides the latest technology in the design of surface, sprinkler, and microirrigation systems along with basic information about soils and current information on estimating crop water requirements. New chapters have been added on planning systems, environmental issues, efficiency and uniformity, chemigation, and use of wastewater for irrigation."--Preface







Engineering Hydrology for Natural Resources Engineers


Book Description

This fully revised edition provides a modern overview of the intersection of hydrology, water quality, and water management at the rural-urban interface. The book explores the ecosystem services available in wetlands, natural channels and ponds/lakes. As in the first edition, Part I examines the hydrologic cycle by providing strategies for quantifying each component: rainfall (with NOAH 14), infiltration, evapotranspiration and runoff. Part II examines field and farm scale water quality with an introduction to erosion prediction and water quality. Part III provides a concise examination of water management on the field and farm scale, emphasizing channel design, field control structures, measurement structures, groundwater processes and irrigation principles. Part IV then concludes the text with a treatment of basin-scale processes. A comprehensive suite of software tools is available for download, consisting of Excel spreadsheets, with some public domain models such as HY-8 culvert design, and software with public domain readers such as Mathematica, Maple and TK solver.




Coping with Water Scarcity


Book Description

One of the main problems confronting the world of the 21st Century is a shortage of water. There is already severe scarcity in many regions of the world, causing tremendous problems for local populations and indeed entire societies. There is insufficient water available for the production of food to alleviate poverty and starvation; the lack of water hampers industrial, urban and tourism development, forcing restrictions on other sectors, especially agriculture; health problems arise as the deterioration of ground and surface waters favours water-borne diseases, which flourish in the absence of decent water distribution and sewerage systems. Water conflicts still arise in areas under stress, while water for nature has become a vanishing priority in such zones. This book is a guide to the establishment of regional and/or local guidelines for developing and implementing new ideas for coping with water scarcity. The basic premise underlying the book is that water scarcity will persist, so personal, human and society-wide skills will be needed to cope with it while living in harmony with the necessary environmental constraints. The book provides basic information to assist decision makers, water managers, engineers, agronomists, social scientists and other professions (and their students) in formulating coherent, hopefully harmonious and consolidated views on the issue. Guidelines are also given for introducing the general public to the concept of water scarcity and how to deal with it.

Practical Applications of Agricultural System Models to Optimize the Use of Limited Water


Book Description

Completely devoted to applicati on of models to opti mize the use of limited water and nutrients in various climates, this collecti on will inspire confi dence in the capacity of modeling to tackle the biggest threats to secure agriculture. To obtain the most producti on from available water while maintaining natural resources, we need whole system–based quanti tati ve knowledge and tools to help select appropriate crops and manage water and associated inputs on a site-specifi c basis under changing climate. Site-specifi c experimental results are available for limited locati ons, limited periods of ti me, and limited management opti ons. Well-tested process models of cropping systems can extend fi eld research results to long-term weather conditi ons, as well as other climates and soils, allowing us to explore new management opti ons. The case studies in this volume are promising examples of these kinds of soluti ons.




Irrigation and Drainage Engineering


Book Description

This textbook focuses specifically on the combined topics of irrigation and drainage engineering. It emphasizes both basic concepts and practical applications of the latest technologies available. The design of irrigation, pumping, and drainage systems using Excel and Visual Basic for Applications programs are explained for both graduate and undergraduate students and practicing engineers. The book emphasizes environmental protection, economics, and engineering design processes. It includes detailed chapters on irrigation economics, soils, reference evapotranspiration, crop evapotranspiration, pipe flow, pumps, open-channel flow, groundwater, center pivots, turf and landscape, drip, orchards, wheel lines, hand lines, surfaces, greenhouse hydroponics, soil water movement, drainage systems design, drainage and wetlands contaminant fate and transport. It contains summaries, homework problems, and color photos. The book draws from the fields of fluid mechanics, soil physics, hydrology, soil chemistry, economics, and plant sciences to present a broad interdisciplinary view of the fundamental concepts in irrigation and drainage systems design.




Irrigation Manual


Book Description

This manual (most of whose modules were originally published 2001-2002) aims at strengthening various aspects of irrigation development, mainly emphasizing the engineering, agronomic and economic aspects of smallholder irrigation, in view of the limited practical references available in this area. It also introduces the irrigation practitioner to the social, health and environmental aspects, providing a bridge between the various disciplines involved in irrigation development.--Publisher's description.




The Biology of Horticulture


Book Description

This comprehensive book provides a thorough scientific foundation on the growth and care of plants common to all horticultural commodities. Continuing in the tradition of the first edition, it incorporates the principles behind the techniques described in other ``how-to'' horticulture texts. By providing readers with a thorough grounding in the science of horticulture, it successfully prepares them for more specialized studies in nursery management, floriculture, landscaping, vegetable and fruit science.




Handbook of Plant and Crop Stress, Second Edition


Book Description

Detailing interrelated topics, this work addresses issues and concerns related to plant and crop stress. This edition includes information on pH stress, temperature stress, water-deficit conditions, carotenoids and stress, light stress, pollution stress, agrichemical stress, oxidative damage to proteins, UV-B induced stress and abiotic stress tolerance.
