New Strategy for Optimizing Water Application under Trickle Irrigation
The determination of water application parameters for creating an optimal soil moisture profile represents a complex nonlinear optimization problem which renders traditional optimization into a cumbersome procedure. For this reason, an alternative methodology is proposed which combines a numerical subsurface flow model and artificial neural networks ~ANN! for solving the problem in two, fully s...
متن کاملیک مدل نیمه تجربی به‌منظور تخمین ابعاد جبهه رطوبتی در آبیاری قطره‌ای، تحت منبع نقطه‌ای
For an appropriate drip irrigation system design, a prediction of soil wetting pattern is needed for a given soil texture. The wetting pattern geometry is a key factor for emitter distance determination as well as crop type. The geometry of the wetting bulb is dependent on the parameters such as soil hydraulic properties, emitter discharge and the irrigation time. This study has been conducted ...

متن کاملExperimental and Numerical Analysis of Drip Tape Layout for Irrigation of Sugarcane in Latosol
A laboratory soil column experiment was first conducted to analyze water movement in latosol of sugarcane field under drip irrigation from single-point source at different emitter discharge rates. Next, a mathematical model of soil water movement under drip irrigation from single-point source was built using Hydrus-3D, which could accurately simulate the shape of the wetted soil volume and the ...
متن کاملپیشروی جبهه رطوبتی از منبع نقطه ای در سطوح شیب دار
To determine the effects of field slope, emitter discharge, irrigation water volume and soil texture on soil moisture profile and soil surface wetted shape from a point source, field data were collected on three different soil types, three emitter discharges (4, 8, and 12 lph), four slopes (0, 2, 5, and 10%), and five irrigation water volumes (10, 20, 30, 40, and 50 liters) with three replicati...
