Lateral subsurface flow (LSF) is a phenomenon frequently occurring in the field induced by local water saturation along horizon boundaries under nonequilibrium conditions. However, observations of LSF undisturbed soils controlled irrigation laboratory are limited but needed for model improvement, prediction, and quantification LSF. We present method extracting an soil monolith boundary introduc...

ABSTRACT-Application of models for simulation of solute and pollutants transport in soil can reduce time and costs for remediation process. HYDRUS-1D model was developed to simulate the one–dimensional flow of soil water, heat, solute and viruses in variably saturated–unsaturated porous media. The objective of this investigation is to determine the solute transport parameters in disturbed soil ...

Abstract Due to the high cost of large-scale measurement heavy metals, use statistical land models and techniques is one proper ways study their distribution level pollution. The area, agricultural lands south Tehran in Iran. Municipal wastewater often used for irrigation under surface method. To metals including copper, nickel, lead, ordinary kriging method GIS environment was used. In additio...

Minimally invasive glaucoma surgery (MIGS) has been gaining popularity over the last decade. Although there is no strict definition for MIGS, all the new procedures share the common theme of intraocular pressure reduction with minimal tissue destruction, short surgical time, simple instrumentation and fast postoperative recovery. The use of glaucoma drainage implants has long been the tradition...

Artificial capillary barriers (CBs) are used to improve root zone conditions as they can keep water and nutrients in the by limiting downward percolation. Numerical analysis is one of promising tools for evaluating CB systems’ performance during cultivation leafy vegetables. This study aims investigate effects system on soil dynamics spinach a column under different irrigation scenarios using H...

Population growth and the associated increase in use of Onsite Wastewater Treatment Systems (OWTS) Black Hills have been a reason for interest nitrate contamination within public water supply over past few years. The main concern is presence karst formation that all OWTS wastewater travel faster, limiting natural attenuation contaminants. treatment performance common soils wood-based media was ...

In most fruit tree orchards under localised irrigation, only a fraction of the rhizosphere is wetted by irrigation. As this may reduce growth and production, such that there demand for information on optimum number location emitters. mature ‘Arbequina’ olive orchard with 1667 trees ha-1, we analysed impact applying same amount water one vs. two drip irrigation pipes (laterals) per row. We had f...
