Abstract The exponents of the advance and infiltration power laws have been shown to remain practically constant for different furrow irrigation discharges. Under this hypothesis, a procedure to estimate the advance and infiltration equations corresponding to untested discharges was developed. The proposed procedure was validated with different field experiments, obtaining satisfactory results for non-erosive discharges. However, significant deviations were obtained when erosive discharges were used. This behavior corroborates the hypothesis presented by some authors that the erosion and sedimentation processes occurring in furrow irrigation as a consequence of high surface velocities can reduce—and even suppress—the effect of the wetted perimeter on the infiltration rate. Finally, an equation was derived to predict the effect of the wetted perimeter on the infiltration parameters.

In application of the volume balance (VB) models, it is generally assumed that the average depth of surface water is constant. This basic assumption may cause significant errors in computing advance. In this paper an accurate algebraic VB equation is developed to predict the advance phase in surface irrigation. In the suggested analysis the average surface water depth is considered to be variable in time. By systematic analysis of accurate kinematic-wave (KW) numerical solutions, the behavior of...

Infiltration parameter estimation (IPE) is a simulation model of furrow irrigation that allows us to estimate infiltration parameters in real time. The model calculates infiltration parameters from measured advance times in the field using a kinematic wave model that includes spatial and temporal variability of infiltration due to variations of the wetted perimeter. The model then calculates cutback inflow rates to reduce runoff and the irrigation application time as a function of the required w...

The volume balance (VB) algebraic equations based on the power advance assumption (i.e., the time invariance of the subsurface shape factor) may deviate significantly from accurate VB numerical solutions. By systematic analysis of the accurate VB numerical solutions obtained using the Kostiakov infiltration formula, the behavior of the subsurface shape factor as a function of time is examined. A new equation describing the time variation of the subsurface factor is derived. Using dimensionless a...

A volume balance approach to determine the parameters of the Kostiakov or modified Kostiakov infiltration equations in border and furrow irrigation is presented. The approach requires measured data from the advance phase, the postadvance (wetting) phase, or both, resulting in three different procedures to characterize infiltration. Using the entire field length the procedures provide infiltration parameters that are more representative of an actual irrigation. The volume balance computation perf...

Abstract Furrow irrigation, the most common irrigation method in California, can be difficult to manage efficiently because of lack of quantitative information on infiltration rates. Conventional methods of measuring infiltration rates are not likely to be used on routine evaluations of furrow irrigation system. However, volume-balance simulation models of furrow irrigation, which estimate infiltration from water advance data, offer a potential for estimating infiltration in furrows. Six models ...

A new method for describing infiltration during filling and draining of cavities such as, for example, irrigation furrows is presented. The model development decomposes in a first step the two-dimensional (2D) infiltration phenomenon into a series of one-dimensional (1D) processes, which are described by an extended analytical solution of the 1D Richards equation (which incorporates the varying effect of gravity). A special integration over the wetted perimeter of the cavity includes rigorous de...

The computation of wetted-perimeter–dependent intake in a furrow irrigation simulation model using an empirical infiltration formula was examined. Different formulations were applied under increasing and decreasing depth of flow (and wetted-perimeter) conditions. Four computational methods were compared for the former condition and only one was tested for the latter. The merit of the procedures was evaluated in relation to the performance of a finite difference unsteady surface flow model. The h...

Infiltration theory and previous studies show that furrow infiltration increases with wetted perimeter. This effect can strongly influence water distribution along furrows. Stagnant blocked-furrow measurements on Portneuf silt loam soil supported this relationship. However, both recirculating infiltrometer and field-scale measurements showed no consistent infiltration:wetted perimeter relationship. The infiltrometer data, collected using a wide range of flow rates on a wide range of slopes, did ...

Average infiltration rates for large land areas can be quickly determined using a new procedure for obtaining the coefficients of the Kostiakov equation. By introducing the concept of the average opportunity time it is possible to plot the infiltration function directly from tabulated data. This modification of the volume‐balance method is a straightforward one, which is easy to understand and learn.

Abstract Traditional border irrigation designs have rarely considered that soil infiltration can vary. The design of border irrigation systems can be improved by the optimization of border irrigation discharge. Therefore, the objectives of this study were (1) to expand the scope of the existing model for estimating and verifying the performance indicators of closed-end border irrigation; (2) to analyze the effect of infiltration variability on infiltration depth variability of closed-end border ...

Abstract A fundamental and widely applied concept used to study surface flow processes is the advance-time curve, which indicates the time at which water arrives at any given distance along a field length. The advance-time curve is typically characterized by an empirical power law with an exponent r and a numerical prefactor p (i.e., x = p t r ). In the literature, different values of r have been reported for various situations and types of surface irrigation. Invoking concepts from percolation ...

Water infiltration and storage under surface irrigation are evaluated, based on the initial soil water content and inflow rate as well as on the irrigation parameters and efficiencies. For that purpose, a field experiment was con - ducted using fruitful grape grown in alluvial clay soil at Shebin El-Kom in 2008 grape season. To evaluate the water storage and distribution under partially wetted furrow irrigation in comparison to the traditional border irrigation as a control method, two irrigatio...

AbstractInfiltration in irrigated furrows depends on the variation of depth of flow and, thus, wetted perimeter along the field and in time. However, the magnitude of the wetted perimeter effect has not been clearly established due to soil variability, erosion and deposition, macropore flow, and other processes that affect the infiltration process. Hence, furrow irrigation models currently offer various alternatives, mostly empirical but some physical, for modeling the infiltration process as a ...

Soil infiltration refers to the soil’s ability to allow water movement into and through the soil profile. It allows the soil to temporarily store water, making it available for uptake by plants and soil organisms. The infiltration rate can be restricted by poor management. Under these conditions, the water does not readily enter the soil and it moves downslope as runoff or ponds on the surface, where it evaporates. Thus, less water is stored in the soil for plant growth, and plant production dec...

An artificial neural network (ANN) was developed for estimating the infiltrated water volume (Z) under furrow irrigation. A feed-forward neural network using back-propagation training algorithm was developed for the prediction. Four variables were used as input parameters; inflow rate (Qo), furrow length (L), waterfront advance time at the end of the furrow (TL) and infiltration opportunity time (To). The Z was the one node in the output layer. The data used to develop the ANN model were taken f...
