Hole-ephemeral gully is a media process between ephemeral gully and gully.It has very important significance for us to understand in advance the laws of gully erosion.However

little research on hole-ephemeral gullies in prior literatures has been done.A small catchment on the Inner-Mongolian Plateau is regarded as a case study and Global Position System(GPS) is used to measure the morphology parameters of hole-ephemeral gullies and topography of the study area.It discusses relative characteristics of hole-ephemeral gullies and analyzes the relationship(S-A)between slope gradient(S)at gully head and upslope drainage area(A)for hole-ephemeral gullies and the relationship(V-L)between lengths(L) and erosion volumes(V)for hole-ephemeral gullies in order to promote the studies on hole-ephemeral gullies.
