That pipe is 1. a generally small, sub-cylindrical, vertical hole developed in an unconsolidated sedimentary deposit by the washing away of all or part of its fines content. some pipes develop above points on a carbonate-rock surface, such as joint intersections, where ground-water seepage is locally concentrated. pipes in chalk include cylindrical and conical masses of clay and sand that are neptunian fills of dissolutional dolines, shafts and caves; all shapes and sizes are commonly referred to as chalk pipes [9]. 2. small cylindrical hole in unconsolidated sediments, caused by removal of fine material by water [10]. 3. a closed tubular conduit for fluid transport [16].?

Flash flood hydrology in karstic terrain: Flumineddu Canyon, central-east Sardinia
Abstract:

In the last five winters (2004–2008) several exceptional meteorological events producing flash floods have been registered in central-east Sardinia. The first of these (December 2004) was the most severe and caused important geomorphic changes in the Riu Flumineddu watershed where the influence of human activity is limited. The hydrological characterisation of this flood is extremely difficult because of the lack of streamflow gauges and the relative paucity of meteorological stations in the region. Peak discharge of the fluviokarstic Riu Flumineddu Canyon has been estimated based on a distributed hydrological model (TOPKAPI) and on empirical methods based on geomorphic and sedimentological observations. The comparison between the results derived from these independent methods allows us to obtain the best possible estimate of peak discharge. Differences between modelled and measured peak flows can be attributed to water losses and/or gains along the river channel from interactions with the underground karst drainage network.

The December 2004 flood, with an estimated recurrence interval of at least 65 years, generated overbank flow and destroyed several bridges in upstream reaches, caused important changes in channel morphology and sediment distribution and was able to move boulders up to 1 m in diameter in downstream reaches.
