We derive sufficient conditions in order that it grows with finite or infinite speed. Moreover a monotonicity result for the mushy region is proved.The propagation of the free boundary of the solution of the dam problem and related problems.journal articlehttp://www.tandfonline.com/loi/gapa20http://www.tandfonline.commetadata only access517.9Speed of propagationFree boundaryPorous mediaEcuaciones diferenciales1202.07 Ecuaciones en Diferencias
