Border Irrigation Model Selection

Transactions of the ASAE, 1984
ABSTRACT THE capability of zero-inertia, kinematic-wave, and volume-balance models to predict advance and recession phases in free-end border irrigation were compared to field data for different values of border width and discharge in a loamy and sandy loam soil. All models give very good predictions of the advance.

Management Contours for Border Irrigation

Journal of Irrigation and Drainage Engineering, 1984
A present capability exists for analysis of a border irrigation by the use of mathematical models of the process or by the use of curves representing generalized dimensionless results thereof. The corresponding synthesis, design of appropriate inflow rates and cutoff times for a given border, currently not so well established, is treated herein.

Border Ditch Irrigation in Colorado

Transactions of the ASAE, 1982
ABSTRACT THE border ditch method is a labor intensive form of surface irrigation that is most appropriate for crops with deep root zones and large water requirements. Ir-rigating a field using the method requires irrigator ex-perience gained from trial and error experimentation on that particular field.

Muskingum Model for Border Irrigation

Journal of Irrigation and Drainage Engineering, 1988
A mathematical model for border irrigation is developed using the spatially lumped continuity equation and the Muskingum type storage relation. The storage parameter is determined from physical border characteristics. The model is calibrated and tested using twentyfour experimental data sets, and yields satisfactory results.

Mathematical Model of Border Irrigation

Journal of the Irrigation and Drainage Division, 1980
The model can predict the rates of advance and recession and the duration and depth of infiltration at any point in a border when slope, length, roughness, inflow rate and infiltration rate are specified. It provides an accurate and economical way to analyze the hydraulics of border irrigation, and thus can enable designers and operators to find ...

Normalized Graphs of Border‐Irrigation Performance

Journal of Irrigation and Drainage Engineering, 1984
Good irrigation management requires the ability to predict the outcome of any given combination of field and management parameters—soil infiltration characteristics, border length, slope and roughness, and inflow rate and cut‐off time in the case of simple border irrigation.
