Question
Transcribed Image Text:5. Field capacity
Field capacity may be defined by pressure threshold (= -340 cm) or by a threshold in specific
discharge (q=0.1 mm/day). Use the Brooks and Corey equations (Tables 7.2 and 7.4 in Dingman) to
estimate the field capacity (8) of the following media according to both definitions. Assume soils are
mineral (0% organic carbon content). Complete your calculations for one example media on engineering
paper using standard engineering format as given in the Problem Solving template. Enter all answers
into the table below.
