Hydraulics of interrill overland flow on stone-covered desert surfaces
The hydraulics of composite overland flow around surface stones are extremely complex and have been little studied. The purpose of this paper is to review both field and laboratory research on this subject and to discuss briefly the implications

Natural use of stone and organic mulches for water conservation and enhancement of crop yield in semi-arid areas
Three experiments were set up to study the effects of stone and organic mulches, applied at different rates, on runoff, evaporation, soil moisture storage and crop yield. Both mulch types reduced runoff and evaporation losses, and the intensity
of reduction increased with mulch application rate. Thus stones were found to be more efficient than Euphorbia as mulch for moisture conservation and crop yield enhancement under semi-arid conditions.

Stone piles have occurred in several parts of Latin America since pre-Columbian times, typically located at mountain passes and crossroads. Their functions are often the same in widely separated areas. - (DWG)

Theoretical model experiments demonstrate that non-periglacial sorted nets can develop on any piece of unobstructed ground surface that has little or no gradient, if it bears a loose, discontinuous cover of pebble-sized stones and if these particles

polygons is connected with cracking of the seasonnaly frozen surface layer combined with rapid infilling of the cracks by sand, gravel, and stones as a result of sorting of surface material due to wind action, rainsplash, drifting snow, and probably also

The goals of the research were to relocate the site; collect exposed bone or stone artefacts; examine the site stratigraphy in the light of current understanding of regional late Quaternary history; and date the site radiometrically. This paper
