“…In Eq. 19, α, m and n are fitting parameters in van Genuchten's model assumed to be 0.03917 cm −1 , 6.63, and 0.849, respectively, according to one of Van Geel's experiments (Van Geel and Roy 2002). Figure 9 compares the numerical simulation results to the exact solution for Case A.…”

“…Kool and Parker [10] and Kaluarachchi and Parker [8] indicated that the deviations in the predicted NAPL flow were significant without considering hysteresis, especially for three-phase systems. Van Geel and Roy [24] proposed a model to incorporate a residual NAPL saturation into an existing hysteretic three-phase parametric model developed by Lenhard and Parker [13]. Their proposed model is similar in form to the entrapment model proposed by Parker and Lenhard, a model based on an expression presented by Land [12].…”

“…A víz maradvány telítettsége a hidrológiai értelmezés szerint -az a folyadéktartalom, melynél a talaj relatív áteresztése nullára csökken -meghatározható az SWRC függvény paramétereként ( VAN GENUCHTEN, 1980), illetve a k r -P függvény illesztésével (LENHARD et al, 2004). A századfordu-lót követően képzett összefüggések szerint a maradvány NAPL-telítettség változó-ként (WIPFER & VAN DER ZEE, 2001; VAN GEEL & ROY, 2002;OOSTROM & LENHARD, 2003;LENHARD et al, 2004;OOSTROM et al, 2005) vehető számításba.…”
