The A. reports on the progress in describing and explaining variation of biodiversity in tropical rain forests. He bases this review on a search of the 1997 editions of Ecology Abstracts, Ecological Abstracts and Forestry Abstracts.
Sediment-transport competence of rain-impacted interrill overland flow
This paper investigates the transport of particles in shallow, rain-impacted flow. Specifically the relationships among rainfall energy, flow energy and transport distance will be investigated. From this investigation a definition of competence
for such flow in terms of transport distance (i.e. a finite distance in a finite time) will be presented. Using the data obtained from the investigation, a predictive equation for sediment-transport competence of rain-impacted shallow flow will be developed.
Climatology of wind-driven rain for the contiguous United States for the period 1971 to 1995
Rainfall that is pushed along horizontally by the wind is referred to as wind-driven rain (WDR) or driving rain. Water penetration of exposed building surfaces is enhanced with WDR, and structural damage is accelerated with repeated WDR exposure
Trampling of microphytic crusts on calcareous soils, and its impact on erosion under rain-impacted flow
This paper examines the effect of simulated trampling on erosion from intact microphytic crust-dominated monoliths subjected to rain-impacted water flow. Using an artificial sheep hoof, 5 intensities of trampling were imposed on the soil surface
A field investigation was conducted 9 March 1994 on a dissipative beach to compare wind characteristics and aeolian transport during and after a light rain, at Wildwood, New Jersey. The amount of sand trapped at Wilwood during rainfall is relatively
high when compared to many previous studies on beaches in the absence of rain. The great length of the beach as a source area, combined with parallel or oblique winds are significant in increasing rates of sediment transport.
two rain events, in a small catchment in andesitic lavas : Rowantree Burn at Sourhope, Scotland. The results show that the concentration of strontium in the streamwater was inversely proportional to the flowrate.
The uplifting Sikkim Himalaya are invaded every 20-40 years by extreme floods caused by continuous rains, exceeding 600-1000 mm in 2-3 days. Steep slopes, permeable soils and deforestation cause a simultaneous passing of thresholds of the slope
The development of ecotones positively depends on temperature, rain and water level. From among the many scenarios of global climate change, two : the GISS and GFLD scenarios have been considered in relation to their effect on freshwater ecosystems
During the Holocene were identified episodes with higher frequency of extreme events like heavy downpours, continuous rains, rainy phases, rapid decades. All of them are reflected in sedimentary sequences, in relief and biotic changes
. The A. distinguish the effects of heavy downpours, continuous rains and extreme rainy seasons, as well as snowmelt floods visible in transformation of slopes and river channels. This examination shows a random distribution in 20-th century with few clusterings
