“…The model has been previously used and verified in a large number of studies (e.g., Bah et al, 2009;Boudreau et al, 2009;Cao and Gong, 2003;De Vos et al, 2000;Endo et al, 2009;Gribb et al, 2009;Hao et al, 2008a,b;Heatwole and McCray, 2007;Hernandez, 2001;Liu and Xie, 1998;Meng et al, 2004;Sanchez et al, 2003;Šimůnek et al, 2008c;Wang et al, 2005;Xu et al, 2005). For example, Forkutsa et al (2009) used the model to simulate water flow in fields with irrigated cotton and shallow groundwater on loam and sandy loam soils of the Khorezm region, located in the downstream part of the Amudarya River. Also, Shouse et al (2011) used the HYDRUS-1D model for simulating root water uptake from a soil profile with shallow saline groundwater.…”
