humus-water grooves


humus-water grooves
   This is a special type of meandering karren or wall karren in which the water originated in humus covering. Water originating from a humus cover has an excess of CO2 and is therefore, very aggressive and can dissolve large amounts of limestone. Thus humus-water grooves can be very deep but after approximately 2–3 meters, the grooves flatten out and continue as normal meanders or wall karren [3]. See also meander karren; wall karren.
