Abstract

A simultaneous transport of water and glyphosate was studied experimentally and numerically. A greenhouse experiment was achieved for collecting data on the water content and glyphosate concentration. A numerical model (LEACHM) was used for simulating these data. Simulated results were compared with experimental data. Experiments were conducted in one-end open PVC columns (0.056-m ID and 1-m high) using unsaturated sandy soil under the atmospheric condition of Buridah, Al-Qassium, KSA. The soil had an initial water content of 0.0802 m3/m3 and zero glyphosate concentration. Two soil columns lasted for 30 days and the other two for 60 days. Glyphosate solution was added at the open end of soil column then followed by adding distilled water at diffe
