Описание: This book presents a newly designed dynamic fluidic sprinkler (DFS) to improve hydraulic performance of the existing complete fluidic sprinkler (CFS) under low-pressure conditions. Sprinkler irrigation has high prospects for improving water management in crop production. In recent years, low-pressure water-saving has become an important research content in the field of sprinkler irrigation. It introduces the effect of riser height on rotation uniformity and application rate of the dynamic fluidic sprinkler. It also discusses the intelligent sprinkler irrigation technologies for autonomous and remote sensing system. This book will be a useful reference for researchers and professionals in the field of agriculture and irrigation.
The rate of global increase in water abstraction for irrigation has been declining since the 1970's due to declining potentials for large and medium-scale irrigation developments, and is expected to further decline in the next decades. As such the significant proportion of the expected increase in production would have to be supplied from existing irrigated and /or cultivated lands. This in turn could be achieved by enhancing land and water productivity through improved performance and optimal operation and maintenance.
With less than 15% of over 5 million ha irrigation potential harnessed, irrigation devolvement in Ethiopia remained low. Over 70% of the developed irrigation in the country belongs to small-scale irrigation serving smallholder farmers. While accelerated development of new irrigation, particularly of large and medium-scale schemes is relevant in Ethiopia, ensuring the performance and sustainability of existing schemes is also equally important. The existing irrigation schemes in Ethiopia are generally characterized by an overall performance and technical sustainability levels of below expectation.
This thesis evaluates the performance of two large-scale (Wonji-Shoa and Metahara) and two community-managed (Golgota and Wedecha) irrigation schemes located in the Awash River Basin of Ethiopia. The study focussed on hydraulic/water delivery performance in the large-scale schemes, and on comparative and internal irrigation service (utility) evaluation in the community-managed schemes. Water delivery performance was evaluated using routine data and hydrodynamic modelling. Farmers' utility was evaluated using qualitative responses of water users. Major performance challenges in each category of schemes were addressed and operational/water management options for improvement were identified.

Описание: A comprehensive overview of the geomorphological processes that shape rivers, combining process-based theoretical and geohistorical approaches. It discusses how the dynamics of rivers are being affected by human activity, and how river management techniques which work together with the dynamics of rivers can best be used to restore these systems.

Описание: This book examines the nature and impact of irrigation system rehabilitation on increasing the actual area irrigated by the publicly funded canal irrigation systems of the Philippines. It proposes a system diagnosis approach for the development of a more appropriate and climate-smart irrigation modernisation plan. It investigates the validity of the design assumptions on percolation and the prospects of water availability estimation as well as characterizes the system operation and management. The book outlines a strategy for formulating a modernisation plan for the case study systems and for government-owned canal irrigation systems in the Philippines in general.

Описание: This book aims to bring forth and address the major issues confronting the irrigation sector of India and also to suggest policy pointers to sustain it. As the policy and reform canvas is large for a huge and diverse country, this book has particular focus on the most important and immediate issues and future options. The chapters not only focus on new research, in-depth analysis and technical details, but also provide a balanced review of the state of irrigation sector and comprehensive presentation of major issues, challenges and future options. With the presentation of in-depth analysis and synthesis of available knowledge, the work can act as a handbook for major irrigation water issues, actual policy changes, and potential reform that could turnaround the sector. Given the temporal and spatial data analysis of the irrigation sector, this book will be effective and useful as a research and teaching tool to students and researchers both in India and globally. Besides its professional audience within the academic, research and policy community, the non-technical format of the book will appeal to a general audience in the media, policy, and donor circles

Описание: The book focuses broadly on the preliminaries of the canal irrigation systems in India with a focus on their operation, maintenance, and management of the canal systems. The chapters in this book are classified under four sections, viz., (i). preliminaries of the canal irrigation systems, (ii) operation of the canal irrigation systems, (iii) maintenance of the canal irrigation systems, and (iv) management of the canal irrigation systems. The preliminaries of the canal irrigation systems include an integrated view of irrigation and agriculture, irrigation management in India: problems, issues, a brief history, and some lessons, irrigation administration, organizational structure for management of irrigated agriculture, and farmers’ participation. The operation of the canal irrigation systems includes the operation of dams and barrages, canal operation, water distribution planning, measurement of flow and sediment in canals, and performance evaluation of the canal irrigation system, use of groundwater in the canal command area. The canal irrigation systems' maintenance includes dams, barrages, related equipment, canals and related structures, field drainage, diagnostic analysis of canal irrigation system, soil and water quality management, soil moisture, and measurement. The management of the canal irrigation systems includes rehabilitation and modernization and a case study on rehabilitation, conjunctive use management, operation, and maintenance budgeting, and financing. The book is expected to be useful for academicians, water practitioners, scientists, water managers, environmentalists, administrators, NGOs, researchers, and students who are actively involved in the operation, maintenance, and management of the canal irrigation system for addressing the challenges being faced in the irrigated agricultural while addressing issues of canal irrigation systems in South East Asia.
