Fig. 5. Observed and simulated effluent concentration curves (Fig. 5a) and spatial distributions (Fig. 5b) for X174 and MS2 in 150-µm sand in the absence of manure suspension and at 5 and 20°C. Here simulations considered 1-site kinetic deposition according to Eq. [1], [3], and [4]. Model parameters are provided in Table 4.
