Question

For a sandy loam soil, using the Green–Ampt equation to calculate the infiltration rate (cm/hr) and cumulative infiltration depth (cm) after 1, 60, and 150 minutes, if the effective saturation is 30 percent. According to the results from an experiment (by draining the sandy loam soil in stages), = 4.52 cm and  = 1.63; the soil porosity is 0.463, and the residual moisture content is 0.110, and the hydraulic conductivity is 1.09 cm/h. Assume a continuously ponded condition; use the given information here.

Answer 1

ANSWER :

Given that :

the hydraulic conductivity (k) is 1.09 cm/h.
