Physical processes leading to failure and entrainment of slightly cohesive material initiated by groundwater seepage
 Světlík, Daniel ; Bruthans, Jiří (advisor) ; Mašín, David (referee)
Relatively recently the geomorphologists have realized that beside the overland flow the groundwater flow emerging from porous rock or soil can under specific conditions cause erosion of that material and create land forms. The goal of this theses is to demonstrate the importance of seepage erosion, which on many places on the Earth contributes to the landscape development, and also to describe the physical nature of the erosion processes acting on slightly cohesive material leading to it's entrainment or failure. Special attention is paid to erosion influence of groundwater on stability of streambanks, where in case of suitable hydraulic and geomechanical properties of the material, a perched water table can be developed leading to lateral seepage through a conductive layer and undercutting the bank face.
