  HYDROLOGY OF PRAIRIE POTHOLES IN NORTH DAKOTA - C
The factors governing seepage inflow and outflow to and from potholes are the direction and magnitude of the hydraulic gradient toward and from the pothole; the permeability of the deposits which underlie and border on the pothole, and the water temperature in these sediments.
The pothole is brackish and semipermanent according to the classification of Stewart and Kantrud (1969).
The dissolved-solids concentration in a pothole is increased by evapotranspiration.

 Mystery of Pothole Origins
The pothole is in an isolated crag in the gorge of the Niagara River at Niagara Glen, a park on the Canadian side of the Niagara River.
Oversized boulders in potholes can be explained by an in situ disintegration theory of pothole formation, but the presence of oversize boulders in potholes would be difficult to explain by the conventional hypothesis of erosion by rotation of vortices and vibration of "grinding stones" inside the pothole by currents.
These potholes in basalt boulders at the bottom of the South Esk Gorge, near Launceston, Tasmania, were exposed by the erosion of their contents by the currents of the river.

 On the Interpretation of Potholes
The slowness of the process of abrasion by which the potholes are supposed to have been formed seems to indicate the holes would be long ages in formation, but this problem is further compounded by the fact that the vast majority of all potholes are not in the process of formation at the present time.
Potholes that occur far from streams and valleys, sometimes high up on hillsides and mountains, are explained by geologists as the effects of the great ice ages of the Quaternary.
Potholes may occur wherever the bedrock is covered by a thin cover of gravel and sand, or drift, which when uncovered by natural or human agents exposes them.

Potholes range from a few millimeters to a few meters in depth, yet even the smallest pothole may harbor microscopic invertebrates, and some contain a recently discovered aquatic mite endemic to the region.
Pothole organisms not only have to endure dry spells, but must accurately evaluate conditions and decide when to break dormancy.
Most organisms living in potholes have very short life cycles, as brief as ten days, reducing the time water is required and allowing them to live in the shallow pools.

 Riggsville Pothole - Maine Geological Survey
The potholes were formed when the region was covered by the last great ice sheet prior to the current interglacial episode in which we live.
Similar in origin to potholes seen in modern rivers (Figure 2), the distinction of the Riggsville potholes is that they were carved in the bedrock by meltwater streams beneath the glacier, highly charged with coarse sediment.
Stones accumulating in the pothole are swirled around by the flowing water, mechanically eroding the solid rock and rounding and smoothing the cavity.

 California Division Pothole Patching Demo   (Site not responding. Last check: 2007-10-11)
Perhaps, we should say a big pothole because there's no such thing as a good pothole, and that's why state and local highway agencies throughout the county spend millions of dollars every year to fill and repair potholes.
The asphalt concrete wearing surface was delaminating in the #3 and #4 (truck) lanes, primarily in the wheel paths, to the point where the quality of ride was affected.
So, it works equally well for surface repairs, but its greatest flexibility is in pothole patching, where compaction is the end result of the process and not another operation requiring a separate piece of equipment.
