Abstract: An extension of the double‐sweep technique is presented for solving systems of algebraic equations arising from implicit schemes of the box type for unsteady open‐channel flow. The new technique handles coefficient matrices ...

Abstract: The equations governing the flow of water in irrigation furrows are put in nondimensional form by expressing each variable therein in ratio to an appropriate reference variable. Two systems of reference variables are ...

Abstract: In contrast to borders, water depth in furrows has a primary influence on infiltration. If flow depth remains relatively constant everywhere and infiltration parameters are measured at that depth, volume infiltrated per ...

Abstract: 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, ...

Abstract: 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 ...

Abstract: Kinematic-wave models of surface irrigation assume a fixed relationship between depth and discharge (typically, normal depth). When surface-irrigation inflow is cut off, the calculated upstream flow depth goes to zero, ...
