Following the extreme rainfall event of 22 September 1992 in Southeastern France, an attempt was made to characterize the response of areas cultivated under vines to heavy precipitation. This response was determined in threeways by means of rainfall
factors contributing to peat instability. Tension cracks, resulting from either short-term dessiccation or long-term slow mass movement, are thought to have facilated the rapid transfer of heavyrain to the subsurface peat, causing high pore-water
Two shallow translational slides occurred in blanket peat on Skerry Hill, in November 1991 at sites adjacent to slides activated c. 25 years ago. Heavy rainfall, degraded drainage ditches and slope morphology are considered to have been important
Atmospheric fluxes of heavy metals to the North Sea
these pollutants may be dropped in sea by deposition processes. Heavy metals are principally in the particulate phase. In dry weather conditions these particles are removed from the atmosphere by gravitation, turbulent diffusion and impaction; this is called dry
deposition. During precipitation particles may be captured by rain drops or snow-flakes and dropped into the sea : this is wet deposition.
Flash floods caused by heavy downpours can result in economic damages (local floods). Prediction of such events relies mainly on weather forecast. As predictions of the time and place of heavyrains are not adequately precise, forecasting of fl ash

to heavy precipitation and flooding. An empirical/hydrometeorological approach was applied in conjunction with basin scale topography within a Geographic Information System. The impacts of flooding were exacerbated by anthropogenic influences.

This paper discusses the factors initiating landslides and a large-scale debris flow in the Chonho area of Taipei County, which resulted from heavy rainfall during Typhoon Xangsane in November 2000. The morphology and triggering mechanism
This paper focuses on meteorological conditions associated with slush flows, and their geomorphologic impact in northwest Iceland. The role of heavy rainfall and rapid snowmelt during winter cyclonic activity is highlighted. The most obvious

of the summer. Much of this rain fell on soils that were already saturated and unable to store additional runoff. Arguments that land-use modifications in the Mississippi River basin exacerbated flooding in 1993 are reviewed in detail, and it is suggested
). Association coefficients have been calculated based on the closeness of the match between the movements generated as a consequence of the heavyrains in late 1996 and early 1997 together with previously defined susceptibility levels.
Research above Salme indicates that heavy monsoon rains in the Himalaya may not accelerate soil erosion caused by human land pressure as has been commonly asserted.―(DWG)
