“…Studies by Jamison and Thompson (1967), Yaalon and Kalmar (1978), Bauer et al (1993), Cheng and Pettry (1993) and Coquet (1998) have observed changes in layer thickness and crack volume during the year. Ritchie et al (1972) assessed soil shrinkage/water content relationships in small and large cores.…”

Abstract:Seasonal cracking of the soil matrix results in poor estimates of runoff and infiltration by simulation models due to the changing soil storage conditions. In this study, soil surface elevation changes were measured every two weeks and soil crack volume was calculated for a two-year period at the USDA-Agricultural Research Service, Riesel Y-2 watershed in central Texas. Soil anchors were placed in triplicate at depths of 0Ð15, 0Ð45, 0Ð90, 1Ð50 and 2Ð5 m and relative movement from a monument at 4Ð5 m was measured. Soil movement was translated into crack volume assuming isotrophic shrinkage. A crack flow model was developed for this study that computes crack volume from crack potential, soil depth and soil moisture. Simulated crack volume followed the seasonal trends found in the measured crack volume and was in general agreement with a regression R 2 D 0Ð84. The crack model was incorporated into SWAT (Soil and Water Assessment Tool), a comprehensive hydrologic model. Regression analysis was performed on measured and simulated daily surface runoff with an R 2 D 0Ð87 indicating good agreement. The model was able to simulate surface runoff accurately in winter months when cracks were swelled closed and in the fall recharge events of 1998 when crack volume went from 70 to 10 mm. The relationships between measured crack volume and hydrologic variables simulated by the model were also examined and discussed.

“…In a survey of UK piping, Jones et al (1997) found that 70% of piping was located on the Histosols of upland rural areas, mostly peats and organic soils with high winter rainfall acceptance potential (WRAP classes 5 and 2), having a capacity to shrink and crack (Coquet, 1998), and with distinctive subsurface impermeability discontinuities which focus pipe flow . Jones et al (1997) argued that as much as one-third of UK agricultural land could be affected.…”

“…Bulk density changes were observed for a wide range of soil types when using the tensiometer method (Boivin et al, 2004;Boivin et al, 2006a;Braudeau et al, 2005;Chertkov, 2003;Coquet, 1998). Bulk density was also found to increase from 1.16 to 1.77 g cm − 3 for a loam soil, based on the pressure plate method (Lu et al, 2004).…”
