Estimating soil wetting patterns for drip irrigation using genetic programming

numerical versus empirical models for estimating wetting patterns in subsurface drip irrigation systems

optimal use of water resources is essential to decrease cost and maximize available water resources. subsurface drip irrigation can increase irrigation and water use efficiency. this irrigation method distributes water into the soil, leaving the surface of the soil dry and decreasing evaporation. in the design of subsurface drip irrigation (sdi) systems, the dimensions of the wetted onion deter...

automatic verification of authentication protocols using genetic programming

implicit and unobserved errors and vulnerabilities issues usually arise in cryptographic protocols and especially in authentication protocols. this may enable an attacker to make serious damages to the desired system, such as having the access to or changing secret documents, interfering in bank transactions, having access to users’ accounts, or may be having the control all over the syste...

Using Irrigation to Manage Weeds: A Focus on Drip Irrigation

effect of slope on soil wetting pattern under surface drip irrigation and simulation hydrus-2d model

in this study, effect of slope on soil wetting pattern under surface drip irrigation and simulation with hydrus-2d model evaluated.the physical model made of plexiglas to size 83, 6 and 54 cm (length, width, height) filled with silty clay loam soil was used. to achieve the desired discharge, a small drip irrigation system created that includes a water tank with a fixed height (about 2 meters), ...

Measured and simulated soil wetting patterns under porous clay pipe sub-surface irrigation

Sub-surface irrigation with porous clay pipe can be an efficient, water saving method of irrigation for many less developed arid and semi-arid regions. Maximizing the efficiency of clay pipe irrigation requires guidelines and criteria for system design and operation. In this study, experimental and simulated (with HYDRUS (2D/3D)) soil wetting patterns were investigated for sub-surface pipe syst...
