Water Movement Through Pedal Soils: I. Saturated Flow1
- J. L. Anderson and
- J. Bouma2
Apparent dispersion coefficients were determined with a chloride tracer in 55-cm long undisturbed columns from four pedal soil horizons of three pedons. Five medium subangular blocky structures were compared with five coarse prismatic structures, all with a silty clay loam texture. Dispersion coefficients (D), which could not always be calculated due to “nonideal” behavior of the flow system, were significantly different for the two types of structures. Application of an unlimited quantity of traced water to drained columns resulted in very high dispersion particularly for the subangular blocky structures. Some practical implications of the occurrence of hydrodynamic dispersion are discussed.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
