WebFor example, in Figure 37, if K 1 = 100 m/d and K 2 = 6 m/d, and d 1 = 10 m and d 2 = 30 m, the equivalent K h would be 29.5 m/d (Equation 37). The equivalent K v would be 7.8 m/d (Equation 39).. The theoretical basis for these expressions and an additional example of deriving equivalent hydraulic conductivities for a four-layer system is provided in Box 5.
Alluvium (from Latin alluvius, from alluere 'to wash against') is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings. Alluvium is also sometimes called alluvial deposit. Alluvium is typically geologically young and is not consolidated into solid rock.
