   In Texas we’d get warnings about the “baked clay” nature of the ground after a prolonged drought, and the likelihood of immediate runoff.

   Of course, in places where there was a super high proportion of clay (aka gumbo), great fissures open up as the hydrophilic clay minerals shrink from water loss. Rain on that fills the fissures before it runs off.

   The effect is quite real and has a multitude of causes. Water repellence in sandy soils, collapse of structure in clay soils, Constriction of structure in plants (close up stomata to limit losses) death of plants. Then there is the simple slowing of water flow over more structures in the soil and plant life vs the simple washing away of loose, dry, soil.

   More science please.
