Measurement Tool for Dynamics of Soil Cracks

Creator:

Stewart, Ryan D., Abou Najm, Majdi R., Rupp, David E., and Selker, John S.

Abstract:

Shrinkage cracks in soil function as a dominant control on the partitioning and distribution of moisture fluxes in the vadose zone. Their dynamics influence moisture balance and control water availability for runoff, deep infiltration, and near-surface storage. We present a new low-cost field instrument to monitor the temporal change in...

Hillslope run-off thresholds with shrink-swell clay soils

Creator:

Stewart, Ryan D., Abou Najm, Majdi R., Rupp, David E., Lane, John W., Uribe, Hamil C., Luis Arumí, José, and Selker, John S.

Abstract:

Irrigation experiments on 12 instrumented field plots were used to assess the impact of dynamic soil crack networks on infiltration and run-off. During applications of intensity similar to a heavy rainstorm, water was seen being preferentially delivered within the soil profile. However, run-off was not observed until soil water content...
