Scenario 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 and tape irrigation methods in sugarbeet fields
due to the scarcity of water resources, the need for sustainable development of drip irrigation tape is essential in iran. a number of drip irrigation tape systems used in sugar beet fields of isfahan and chahar mahal va bakhtiari provinces were evaluated and were compared with furrow irrigation methods in two consecutive years. the actual water use efficiency (wuesy, wuewsy) in lower quarter, ...
متن کاملInfluence of Irrigation Water Properties on Furrow Infiltration: Temperature Effects
*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...
متن کاملeffect of every other furrow irrigation on yield of sugarcane in south ahvaz sugarcane fields
sugarcane is cultivated in extensive areas in khuzestan it is irrigated through hydro-flume and in furrows. for an evaluation of the effect of deficit- irrigation on sugarcane yield, this experiment was conducted. the treatments consisted of the conventional irrigation method (blank), variable, every other irrigation, (by alternative furrows) and invariable every other irrigation (by fixing the...
متن کاملErosion Control in Furrow Irrigation Using Polyacrylamide
Currently gravity irrigation remains the most widely used in agricultural areas and 90 percent of plantings, the water is applied to the plots by gravity. One of the main problems with these systems is erosion, which is a by product of the erosive forces of water over the row, which brings soil loss and therefore decreases in crop yield. Erosion is the removal of surface soil material caused by...
