Abstract
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 criterion. For achieving a performance that is close to the design performance, in addition to proper design, a well-defined irrigation schedule must be followed such that the soil moisture deficit at the time of irrigation is close to the design depth. The actual overall performance of a level basin irrigation system will otherwise be lower than the design performance. Using a mathematical simulation model, the performance of a level basin designed using the completion-of-advance design approach was found to be robust rel...

It is essential to standardize the definitions and approaches to quantifying various irrigation performance measures. The ASCE Task Committee on Defining Irrigation Efficiency and Uniformity provides a comprehensive examination of various performance indices such as irrigation efficiency, application efficiency, irrigation sagacity, distribution uniformity, and others. Consistency is provided among different irrigation methods and different scales. Clarification of common points of confusion is ...

ABSTRACT Level basins are designed based upon completion-of-advance irrigation. Designs are used for fields where water control is not practical or practiced. The design determines either the run length or the infiltrated depth when the other is specified. The resulting design provides for applying a relatively constant infiltrated depth when the unit inflow rate varies by a factor of four from a target unit inflow rate.

ABSTRACT Zero inertia modeling was used to evaluate completion-of-advance irrigation in level basins with no run-off for use where inadequate control of water delivery exists. Distribution uniformity was good to extremely high for a wide range of conditions. The average depth of infiltration varied only moderately with large differences in the unit inflow rate. The effects on performance caused by errors in the soil surface parameters were moderate and can be compensated for. Completion-of-advan...

ABSTRACT RECENT advances in the theoretical description and model simulation of surface irrigation now permit the evaluation of existing procedures and development of new and improved procedures for design and management of surface irrigation systems. Such developments are now underway, but their refinement and adoption by institutions and individuals may require considerable time. In the meantime, existing procedures will continue to be used. This paper summarizes an evaluation of that portion ...

Abstract Basin irrigation systems were designed for a constant flow rate. The operation of the designed system was simulated using the zero-inertia model of surface irrigation. The performance of the system was obtained for modified design flow rates. Three patterns of flow variation — sinusoidal, initially low then high, and initially high then low — were studied. The average of a variable flow rate in a given simulation equalled, was less than and greater than the design flow rates. The flow r...

A previous solution for level basin design is expanded to cover a wider range of infiltration conditions. An analysis is performed to determine an approximate limit on basin length which depends upon application depth, infiltration conditions, roughness and the desired uniformity. Once a basin length is determined, the minimum unit flow rate necessary to achieve the desired uniformity is found. Basin area and width are then based on the available stream size. The solution is developed from the z...

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 design...

A mathematical model of the stream flow in border irrigation is presented in the context of negligible accelerations everywhere in the stream. During the advance phase, numerical solution of the governing equations is achieved on an oblique grid in the x-t plane. The equations of motion are integrated over each oblique cell formed by joining the node points at constant times and distances by diagonals. The resulting nonlinear algebraic equations for depth and discharge at the upper corners of a ...

The sustainability of the Hetao Irrigation System, located in the water scarce upper Yellow River basin, is a priority considering the need for water saving, increased water productivity, and higher farmers’ incomes. The upgrading of basin irrigation, the main irrigation method, is essential and includes the adoption of precise land levelling, cut-off management, improved water distribution uniformity, and adequate irrigation scheduling. With this objective, the current study focuses on upgradin...

In this research we explore the potential of precision surface irrigation to improve irrigation performance under the warabandi system prevalent in the Indus Basin Irrigation System. Data on field dimensions, field slopes along with characteristic soil infiltration properties and outlet discharge were collected through a survey of a sample tertiary unit of Maira Branch Canal, Khyber Pakhtunkhwa Province, Pakistan. The performance of all fields in the tertiary unit was analysed and reported in ag...

Water-saving irrigation needs to be implemented in Hetao irrigation district to help satisfying the demand by other users in the Yellow River basin. Aiming at assessing the potential irrigation performance and water saving at farm level, a set of traditional basins and another of precision-levelled basins cropped with maize, wheat and sunflower and managed by farmers were evaluated. Data were collected to characterise the basin sizes, microtopography, inflow rates, advance and recession times, c...

An extensive irrigation system is being developed in Greater Thal Canal area to meet food demand of growing population. In Greater Thal Canal area soils are predominately coarse which results in higher deep percolation losses than those occurring in other cultivated land. Surface irrigation methods are normally used. Infiltration may be described by the Kostiakov Equation. Soil amendments such as bentonite could be used to reduce the water infiltration rate. The objectives of the study were to c...
