Abstract
The procedures are examined for obtaining reasonable estimates of distribution uniformities for a wide variety of flow rates, length of run, infiltration characteristics, and flow resistance for the design and management of level basins. The dimensionless solution of advance and recession in level basins was extended to show the distribution uniformities for a wide variety of conditions. This was then transformed into two representations of distribution uniformity that are more useful for designing and managing level basins. One solution displays the effects of soil moisture deficit and the necessary infiltration opportunity time on distribution uniformity. The other displays the effects of field length and flow rate on distribution uniformity.

AbstractA well-designed level basin irrigation system is easy to manage and has significant potential for achieving high application efficiency and improved salinity control, particularly when the field is laser-leveled. Over the years, three different criteria have arisen to design level basin irrigation systems. These are the volume-balance design criterion proposed by the Soil Conservation Service of the USDA, the limiting length design criterion, and the completion-of-advance design criterio...

The aims of this paper are to analyze theoretically the influence of the longitudinal slope of a surface irrigation field on the uniformity of irrigation and to provide practical tools to design, analyze and manage surface irrigation systems with longitudinal slope and blocked end. An example is shown where a 20% savings in water is obtained by giving the field the optimal slope. In 1982, Clemmens and Dedrick published a practical set of dimensionless graphs to level-basin design and analysis (w...

Level-basin irrigation is extensively used in South-Western United States where water is very expensive. A well designed level-basin irrigation system is easy to manage, and has significant potential for achieving higher application efficiency and improved salinity control, particularly when the field is laser-leveled. Over the years, three different criteria have evolved to design level-basin irrigation systems: the volume-balance design criterion proposed by the Soil Conservation Service (SCS)...

Contour basin irrigation layouts are used in Australia for sequential cultivation of rice and other crops on soils with low infiltration rates. Multiple interconnected basins through gates installed in the check banks and backflow at the inlet end are unique features of contour basin layouts used in southeast Australia. Design and management guidelines were developed using a two-dimensional computer simulation model (COBASIM) for contour basin layouts. The computer model was used to simulate and...

This paper describes a new procedure for the design of level-basin irrigation systems which is based on the irrigator's cutoff criteria. Design with this procedure, hopefully, will be more transferable to users and will allow basin designs to be adopted to local practices. Comparisons are made to existing design procedures, and it is shown that many of them can be expressed in terms of this new procedure, available in the form of a computer program. A sensitivity analysis was used to confirm the...

An open-end graded border design procedure is presented. The proposed method based on the principle of mass conservation requires Kostiakov and Manning formulations for infiltration and roughness, respectively. The key assumption of the present design procedure is that the minimum infiltrated depth occurs at the lower border end and is equal to the required depth of infiltration. The philosophy behind the proposed design procedure is to select the appropriate flow rate q0 and cutoff time Tcof fo...

The surface-irrigation design process requires multiple analyses of surface irrigations to test tentative values of design parameters in the search for an optimum. Preparation of general design charts can aid the design process if the users' test cases fall within the scope of the charts. The large number of independent variables in surface irrigation preclude the generation of charts covering the practical range of all independent variables, when these are in dimensioned form. Dimensionless for...

Se justifican criterios de semejanza hidraulica que son aplicados a la generalizacion de resultados de simulaciones de riegos por superficie convencionales. Las ecuaciones generales de una corriente libre unidireccional son utilizadas para analizar el movimiento del agua en canteros con seccion transversal cualquiera que reciben en cabeza un gasto constante durante un tiempo determinado. A partir de las aproximaciones de los etodos de inercia nula y de la onda cinematica, se definen parametros a...
