THROUGHFALL [6 records]

Record 1 2013-08-13

English

Subject field(s)
  • Atmospheric, Climatic and Meteorological Phenomena
  • Silviculture
  • Forestry Operations
CONT

Hydrochemical investigations were initiated within the framework of a national research programme on forest decline. The objective was to measure simultaneously on plot and catchment scales, the effects of acid atmospheric inputs at all the levels of the ecosystem. Atmospheric pollutants, open field precipitation, throughfall and soil solutions at various depths and in different stands, spring waters and stream waters have been monitored continuously for almost 10 years.

French

Domaine(s)
  • Phénomènes météorologiques, climatiques et atmosphériques
  • Sylviculture
  • Exploitation forestière
CONT

En absence de toute pollution, l'eau de pluie a un pH proche de 5,5. Pour la placette, le pH des précipitations hors couvert forestier est de 5, celui des précipitations sous couvert forestier est légèrement plus 4,8.

Key term(s)
  • précipitations totales hors forêt
  • précipitations totales hors couvert forestier
  • précipitation totale hors forêt
  • précipitation totale hors couvert forestier
  • précipitation hors forêt
  • précipitation hors couvert forestier
  • précipitation brute

Record 2 2012-02-02

English

Subject field(s)
  • Weather Stations and Meteorological Instruments and Equipment
CONT

The automatic recording rain gauge indicates each time there is a rainfall of at least 0.01", hence one may know not only how much rain fell during the day, but also exactly when it rained and the amount every five minutes.

CONT

Rainfall and throughfall were measured for each rainfall event during the monsoon season(June-September) using an automatic raingauge and 96 graduated containers, respectively.

Key term(s)
  • automatic raingage
  • automatic rain-gauge
  • automatic rain gauge
  • automatic rain-gage
  • automatic rain gage
  • automatic recording rain-gauge
  • automatic recording rain-gage
  • automatic recording raingage
  • automatic recording raingauge

French

Domaine(s)
  • Stations, instruments et équipements météorologiques
CONT

La pluie incidente (au dessus de la canopée) et la pluie nette (traversant la canopée) ont été mesurées pour chaque épisode pluvieux de la mousson (juin-septembre) grâce à un pluviographe automatique et à 96 pluviomètres gradués.

Record 3 2004-10-20

English

Subject field(s)
  • Atmospheric, Climatic and Meteorological Phenomena
  • Silviculture
  • Water Pollution
DEF

The precipitation intercepted by leaves and branches, which then flows down the trunks and enters the soil.

CONT

On the other hand, precipitation which is not already strongly acidified may become so by throughfall and, especially, by stemflow.

CONT

Precipitation may become acidified by throughfall through forest canopies or by stem flow.

French

Domaine(s)
  • Phénomènes météorologiques, climatiques et atmosphériques
  • Sylviculture
  • Pollution de l'eau
CONT

[...] une partie ruisselle le long des axes et est collectée par la surface du tronc le long de laquelle elle s'écoule, pour irriguer le sol dans l'environnement immédiat des souches : c'est l'eau d'écoulement (Ec) ou «stemflow».

OBS

L'expression «ruissellement sur les troncs» est employée au Canada.

OBS

L'eau qui s'écoule par le mécanisme dit de l'écoulement est appelée «eau d'écoulement».

Spanish

Campo(s) temático(s)
  • Fenómenos meteorológicos, climáticos y atmosféricos
  • Silvicultura
  • Contaminación del agua
DEF

Agua de lluvia que fluye por ramas y troncos hasta el suelo de un bosque.

English

Subject field(s)
  • Chemistry
CONT

The figures calculated for gross precipitation, throughfall and stemflow are 1. 9, 1. 7 and 1. 4 respectively, indicating that for acidifying potential the ’pathways’ can be ranked gross precipitations [inferior to] throughfall [inferior to] stemflow.
