Bank-collapse processes in a valley-bottom gully, western Iowa

Widening and bank‐slope reduction of a valley‐bottom gully in western Iowa was correlated to increasing subsurface flow over a 36‐year period. To study bank collapse at this gully, we measured rainfall, air temperature, hydraulic head near the banks and bank movement nearly continuously over a 2‐yea...
