ISBN: 9070754290 Tóm tắt: This book provides the multi-projects evaluations of irrigation. It discusses the definitions of of irrigation efficiency, and the relationships between irrigation management indicators and efficiencies and uniformities. It provides with points of attention for the planning, design, and operation of irrigation schemes. It deals with factors that influence irrigation efficiencies. The book also measures values of irrigation efficiencies that can be used as estimaters of values to be expected (hydraulic engineering; irrigation; ) |Thủy công; Thủy lợi; | DDC: 627.52 /Nguồn thư mục: [SCTHU]. |

| 1682559. Irrigation water management (300).- 1st.- Wageningen: Wageneingen Agricultural Univ, 1981; 20p.. Tóm tắt: Objectives: 1) to develop better understanding of the technical, managerial, and socio-instituational factors determining the potential and actual utilization of water in rice irrigation systems and develop procedures to measure them. 2) To develop and determine the effectiveness, through pilot test projects, of alternative methods of water distribution and allocation in different types of irrigation systems to meet specific goals, such as irrigation water savings, distribution equity, and high rice yields. 3) To develop practically useful criteria for irrigation system planning, design and rehabilitation, focusing on two aspects: (i) technical design criteria for field water distribution and allocation, and (ii) economic evaluation of different means of irrigation development (irrigation; ) |Tưới tiêu; | DDC: 631.62 /Nguồn thư mục: [SCTHU]. |
| 1685015. Background papers on water requirements, agronomic, soils and Yield response, concepts in irrigation water management/ IRRI.- 1st.- Los Banos: IRRI, 1980 Tóm tắt: The book deals with the eight subjects followed: 1) Irrigation water management, implies the skilled handling of water, the executive function of planning, organizing, coordinating, directing, controlling water development, procurement, conveyance, measurement control, application, use and removal if in excess, for efficient crop production in agriculture. 2) Water requirements for lowland rice, there are two broad classes of information: the water requirements for growing a crop satisfactorily, and the yield response to water. 3) Water requirements of upland crops, determine irrigation needs, it provides a basic understanding of the terminology involved in consumptive water use, matters of practical utilization for consumptive water use, and the major factors affecting plant water use. 4) Soil water relationships: static soil-water relations and retention relationships in the soil profile are pretinent to the upland condition; dynamic soil-water ralations and movement of water in the soil profile are the important considerations in the lowland paddy rice production environment. 5) Crop water-yield relationships, when crop charcteristics are known, they define the relative value of Y (yield) versus ET (evapotranspiration) function which is then crop characteristics. 6) Problem soil and water managemnet, discusses some basics of problem soil amelioration, and the day to day field soil and related water quality problem. 7) Importance of land preparation, the impact of land preparation on the "turn around time" (the period between cropping seasons)is also considerable since this period is determined by the duration of land preparation for the second crop. 8) Effective use of rainfall in irrigated cropping systems, some irrigation systems with reservoirs, the water saved during the wet season through effective use of rainfall can be used to irrigate the field when water is most valuable (irrigation; water conservation; ) |Thủy lợi; Thủy nông; | DDC: 631.7 /Nguồn thư mục: [SCTHU]. |
