The application of machines and better power sources to enhance agricultural production has been one of the most significant developments in agriculture. Mechanization of agriculture is needed for development and optimal utilization of natural resources leading to higher productivity and reduced cost of production for greater profitability, economic competitiveness and sustainability. Mechanization also imparts capacity to the farmers to carry out farm operations with dignity, comfort and freedom from drudgery, making the farming agreeable vocation for educated youth as well. It helps the farmers to achieve timeliness in farm operations and apply costly input with reduced quantity for better efficacy and efficiency. Small and marginal farmers can now make use of high capacity agricultural machines on custom hire basis. The results of this development can be seen in many aspects such as increase in productivity and production per worker, precision in application of crop inputs, increase in cropping intensity due to timeliness of operations, increase in the quality of produce, reduction in grain losses and increase in farm employment. Mechanization is particularly advantageous when it can minimize a high peak labour demand that occurs over a relatively short period of time each year. Mechanization also encourages better management of farm inputs, improvement in working conditions and performance of jobs that would otherwise be difficult by hand. It also helps in reducing the cost of production. This book 'Mechanization of Cultivated Crops' covers the farm tools and equipment used in different operations such as land development, tillage, seeding/planting, interculture, fertilizer application, plant protection, harvesting and threshing and residue management. The book can be referred as a textbook for the under graduate students of agriculture and under graduate and post graduate students of agricultural engineering.

The book Drip and Sprinkler Irrigation is intended as a text book of micro irrigation design and practices for the students of the agricultural sciences and the professionals and workers in the field of micro irrigation. The book discusses the type and components, hydraulics and design, installation and maintenance of micro irrigation system. It contains good number of numerical as example and task to get the students familiar to the requirements, complicacies, and possible remedies in actual working condition. In addition to conventional broad and short questions in every of the book there are multiple choice questions to assist the students in preparing the competitive examinations.

The world's population is expected to increase to over 8 billion by 2020. About 60% of the total population of the world lives in coastal areas and 65% of the cities with a population of over 2.5 million are located in coastal areas. Written by an international panel of experts in the fields of engineering and risk management, The Handbook of Coastal Disasters Mitigation presents a coherent overview of 10 years of coastal disaster risk management and engineering, during which some of the most relevant events of recent time have taken place, including the Indian Ocean tsunami, hurricanes Katrina and Sandy in the United States or the 2011 Japanese tsunami.

Laboratory physical models are a valuable tool for coastal engineers. Physical models help us to understand the complex hydrodynamic processes occurring in the nearshore zone and they provide reliable and economic engineering design solutions.This book is about the art and science of physical modeling as applied in coastal engineering. The aim of the book is to consolidate and synthesize into a single text much of the knowledge about physical modeling that has been developed worldwide.This book was written to serve as a graduate-level text for a course in physical modeling or as a reference text for engineers and researchers engaged in physical modeling and laboratory experimentation. The first three chapters serve as an introduction to similitude and physical models, covering topics such as advantages and disadvantages of physical models, systems of units, dimensional analysis, types of similitude and various hydraulic similitude criteria applicable to coastal engineering models.Practical application of similitude principles to coastal engineering studies is covered in Chapter 4 (Hydrodynamic Models), Chapter 5 (Coastal Structure Models) and Chapter 6 (Sediment Transport Models). These chapters develop the appropriate similitude criteria, discuss inherent laboratory and scale effects and overview the technical literature pertaining to these types of models. The final two chapters focus on the related subjects of laboratory wave generation (Chapter 7) and measurement and analysis techniques (Chapter 8).

Attempting to extend the boundaries of land reclamation, this publication is a collection of conference papers addressing a range of topics from the practical challenges of cleaning up the most conaminated sites to the creation of new landscapes and the ethical issues surrounding land restoration.

The book describes the current state of former opencast mines in six countries. The remediation and reclamation of abandoned opencast mines are considered as a chance for new sustainable ecological, sociological and cultural developments in the regions concerned. The examples quoted from different countries allow the results of different remediation strategies to be compared. By way of conclusion, some recommendations are given at the end.

This special volume contains papers that are partly based on contributions to the symposium "Minesite Recultivation" wh ich was held at the Brandenburg Technical University in Cottbus, FRG in lune 1994. Ouring this symposium, various aspects of research into the recultivation of open-cast minesites were discussed. As a prime example, the symposium focussed on the recultivation (reclamation) of post-mining landscapes in the Lusatian lignite mining district of the former German 2 Oemocratic Republic (GOR). In this area, about 700 km have been devastated by open- cast mining during the last 70 years. Therefore, the research into recultivation has a long tradition in Lusatia, going back to the 1930's. Oue [0 the scientific isolation of the former GOR, most of the research results were not available to an international audience until now. This situation holds also true for other eastern countries. Hence, this special volume is a first step to fill this gap. The papers by Pietsch, Heinsdorf, and Katzur and Haubold-Rosar detail the Lusatian lignite mining district presenting an overview of recultivation research results and practical experiences related to the establishment of terrestrial and aquatic ecosystems in this region after mining. In particular, the amelioration and reforestation of extremely acid, sulfurous mine soils, the fertilization of forest stands under different mine site conditions and the site-specific recolonization and re vegetation strategies are described.

This monograph provides an overview of the principles required for a service orientation in the management of irrigation and drainage systems. The material covered is designed to emphasize an area largely neglected in the irrigation and drainage management literature. The dominating philosophy underlying this book is that irrigation and drainage systems must be managed as a service business responsive to the needs and changing requirements of its customers. It is postulated that this service approach to the management of irrigation and drainage systems consitutes a key element of the startegy that is needed to improve the current level of performance of many irrigation and drainage systems worldwide. Enhanced performance of irrigation is a prerequisite if we are to face the enormous challenge of producing greater quantities of food to meet the demand of a growing population. This is particularly the case in an environment with increasing competition for water from industry and urban water users, set against mounting concerns about environmental sustainability.

Man's control over the elements of land and water for the purposes of agriculture was fundamental to the development of civilisations in the past, and remains so today. This volume deals with the processes of irrigation, and land drainage and reclamation, and illustrates the variety of technological and engineering solutions in a wide chronological and geographical perspective. The sophistication of many pre-modern systems is clear, as is the impact of modern technologies. Important points that emerge are that there was no steady or linear progression in techniques across time - instances of the transfer of ideas are balanced by cases of independent development - and that the correlations between irrigation systems and social structures demand more complex explanations than often proposed.

Hunt also covers field instrumentation for surface movements, subsurface deformations, and in situ pressures and stresses, as well as instrument arrays for typical problems such as structure settlement and fault movements. Eliminate the need to search through narrow volumes or large handbooks with Geotechnical Investigation Methods: A Field Guide for Geotechnical Engineers, a convenient and complete guide to the techniques you need.

Primarily written as course material on flood control and drainage engineering for advanced students of civil engineering, this third edition is thoroughly revised. It accommodates recent developments in remote sensing, information technology and GIS technology. New additional material deals with problems of flood forecasting, flood plain prioritization and flood hazard zoning, and engineering measures for flood control. Drainage improvement is tackled, with particular regard to salinity and coastal aquifer management from the ingress of sea water. The book includes design problem-solving and case studies, making it practical and applications-oriented. The subject matter will be of considerable interest to civil engineers, agricultural engineers, architects and town planners, as well as other government and non-government organizations

Practical Drainage is easy to read and presented in a non-technical style generously supported with helpful illustrations. There are three key messages in this book: water moves sideways only slowly through soil--leading to a detailed description of how drains work; the how-and-why of perched water table methods of construction; and sands are different from one another--they must be tested before use in turf root zones. These key messages are preceded by detailed descriptions of how water moves into soils and the effects of compaction on that movement. The final chapters give step-by-step guidelines for calculating drain spacings and depths, based on measurements of the hydraulic conductivity of the soil and its various layers. There are also chapters about how to measure hydraulic conductivity and how to design and install sub-soil drainage systems.

Modern Irrigation Technologies reviews the experience of small holders with irrigation technologies under a range of diverse conditions in many different countries. Some people argue that modern irrigation technologies are the key to increased food production. However, projects introducing modern irrigation technologies in the developing world have often failed because the irrigation hardware, which has been developed for high-technology commercial agriculture, cannot be easily adapted for the use of the smallholder. The author identifies the pre-conditions relating to water availability, institutional support and economic opportunity that must be satisfied before small holders in developing countries can adopt irrigation methods and benefit from them. The circumstances in which modern technologies have been introduced are identified, and the relative success or otherwise of the initiatives are summarized. The book also contains a practical review of the range of irrigation hardware that is available and indicates the types of equipment that are more likely to meet the requirements of the smallholder sector. Modern Irrigation Technologies will be an invaluable guide to project workers, planners and small holders involved in planning and designing irrigation projects.

Key Features: Provides clear and authoritative recommendations for managing fire in ecological and social contexts Authors are all international leaders in their fields and include not only academics but also leaders of Indigenous communities Explains Indigenous cultural and knowledge systems to a degree that has rarely been accessible to lay and academic readers outside specialized disciplines like Anthropology Responds to growing need for new approaches to managing human-ecological systems that are in greater sympathy with Australia's natural environments/climate, and value the knowledge of Indigenous people Timely for scholarly and interest groups intervention, as the Australian government is again looking to 'develop the north' Sustainable Land Sector Development in Northern Australia sets out a vision for developing North Australia based on a culturally appropriate and ecologically sustainable land sector economy. This vision supports both Indigenous cultural responsibilities and aspirations, as well as enhancing enterprise opportunities for society as a whole. In the past, well-meaning if often misguided policy agendas have failed - and continue to fail - North Australians. This book helps breach that gap by acknowledging and harnessing Indigenous cultural strengths and knowledge systems for looking after the country and its people, as part of a smart, novel and diversified ecosystem services economy.

This book discusses coastal defense measures, which have not improved in the past few decades, and better alternatives. It emphasizes on the existence of stable bays in coastal geomorphology and their use in coastal stabilization. The conventional measures for saving beaches, such as seawalls, groins, offshore breakwaters, and renourishment, are discussed in detail, followed by an alternative known as headland control. Many types of coast, and the respective defense measures, are discussed, especially for eroding beaches downcoast of harbors with long breakwaters. The formation of offshore bars during storms is examined and the design of stable recreational beaches is demonstrated. Practical design problems are discussed in all cases. Many issues requiring attention in coastal engineering are also outlined.

This book is written for engineers, students of coastal processes and laypersons interested in beach nourishment, which consists of the placement of large quantities of good quality sediment on the beach to advance the shoreline seaward. The improvement of project performance through proper design and the predictability of performance are emphasized. The overall longevity of a project is addressed as are local erosional areas. The roles which wave height, project length and sediment quality play in project performance are addressed quantitatively. The results are illustrated through reference to a number of monitored nourishment projects. Biological and economic aspects of beach nourishment are addressed.
