Comparison of One-point and Two-point Methods for Estimation of Infiltration Parameters in Furrow Irrigation
Infiltration is one of the most important hydraulic parameters affecting surface irrigation and one ofthe most difficult parameters in practical field determinations. The infiltration equations are used todescribe water flow hydraulics and surface irrigation systems design. But determination of theparameters in these equations are costly and time consuming. Therefore, some estimating methods ar...
متن کاملScenario Studies on Effects of Soil Infiltration Rates, Land Slope, and Furrow Irrigation Characteristics on Furrow Irrigation-Induced Erosion
Furrow irrigation proceeds under several soil-water-furrow hydraulics interaction dynamics. The soil erosion consequences from such interactions in furrow irrigation in Samaru had remained uncertain. A furrow irrigation-induced erosion (FIIE) model was used to simulate the potential severity of soil erosion in irrigated furrows due to interactive effects of infiltration rates, land slope, and s...
متن کاملevaluation of furrow irrigation for different inflow hydrographs
furrow irrigation is the most common type of surface irrigation. determine the advance and recession time in the field is required the accurate measurement and this can be costly and time consuming. winsrfr model is used for simulation furrow irrigation by zero inertia and kinematic wave engines. using this model, advance time, reaction time, infiltration depth, runoff depth and application eff...
متن کاملThe Effect of Different Furrow Irrigation Regimes on Infiltration and Sugarcane Yield at Ubombo
In surface irrigation, the soil serves as a medium for infiltration and conveying water from upstream to the downstream end of a field. In this study, infiltration properties of the Sibaya (Si) soil series (Glenrosa in the South African soil classification system) were determined by a volume balance method using a two-point approach technique. The purpose of the study was to examine the effect ...

*R. D. Lentz and D.L. Bjorneberg, USDA-ARS, Northwest Irrigation and Soils Research Lab., 3793 N. 3600 E., Kimberly, ID 83341 USA. *Corresponding author: [email protected] ABSTRACT For surface irrigation, the rate and spatial characteristics of infiltration processes influence crop productivity, water use efficiency, and erosion potential of stream flows. A change in infiltration rate a...
