A Simple, Inexpensive Rain and Canopy Throughfall Collector

Journal of Environmental Quality, 1994
AbstractA field apparatus for collecting rain and canopy throughfall samples for volume and ion analyses was built and tested; detailed construction plans and material lists are included. Its advantages include simple wood and polyvinyl chloride pipe construction, low material costs, and an inert sample collector that remains covered until the rain ...

Variability of throughfall erosivity among crown positions in a teak plantation based on raindrop measurements and throughfall partitioning

2021
<p>Knowledge of throughfall erosivity is necessary for the accurate prediction of soil erosion in some forests with little protective ground cover. This study compared throughfall drops and erosivity between open rainfall and for four different crown positions in a teak plantation in Thailand.

Throughfall chemistry in a spruce chronosequence in southern Poland

Environmental Pollution, 2008
The chemical composition of throughfall and canopy leaching, as well as the acid neutralizing capacity and alkalinity depended on the age of Norway spruce (Picea abies Karst) stands and season of the year. A higher amount of sulphur and strong acids was deposited to the soil in the older age classes.

Throughfall characteristics in three non-native Hawaiian forest stands [PDF]

Agricultural and Forest Meteorology, 2010
The effect of non-native trees on hydrological processes in Hawaiian forests remains largely unquantified. In this study, throughfall was determined by stationary methods over 18-23-month study periods at three locations each dominated by one of three ...

Throughfall variation under tree crowns

Journal of Geophysical Research, 1961
It is suggested that the experimental design for sample measurement of throughfall may be improved. Specifically, distance and direction from trunk may constitute a significant source of variation that could be separated in analysis of variance from the unexplained variation.

Sources of sulphur in forest canopy throughfall

Nature, 1988
Atmospheric deposition of sulphate is the primary link between the atmosphere and acidification of soils and aquatic ecosystems1. The flux of sulphate to forest soils can be measured in the water that drips from trees following the interception of rain to form stemflow and throughfall (the sum of which is designated here as TF).

Walker Branch Throughfall Displacement Experiment

2003
The Walker Branch Watershed (∼100 ha), located at 35°58′ N latitude and 84°17′ W longitude, is a part of the U.S. Department of Energy’s (DOE’s) National Environmental Research Park near Oak Ridge, Tennessee (Johnson and Van Hook 1989). Long-term (50-year) mean annual precipitation is 1352 mm, and mean annual temperature is 14.2°C.

Organic halogens in spruce forest throughfall

Chemosphere, 1998
Abstract Deposition of dissolved organic halogens by throughfall was determined in a small spruce forest site in Denmark (56°28'N, 8°24'E). The mean annual deposition of dissolved organic halogens was 377 g ha−1yr−1, and larger than the general deposition by precipitation.

Throughfall Measurements of Nitrogen and Sulphur Compounds

International Journal of Environmental Analytical Chemistry, 1993
Abstract The wet- and throughfall deposition of nitrogen and sulphur compounds to a spruce forest edge in Sweden was studied using preserved as well as unpreserved collectors. During the warmer part of the year inorganic nitrogen was lost in unpreserved throughfall collectors, if they were not shielded from light.

Stemflow and throughfall in a tropical dry forest

Earth Surface Processes and Landforms, 1990
AbstractThe rainfall received by a small plot of tropical deciduous forest on sand dunes in Veracruz, Mexico, was partitioned into stemflow and throughfall components to determine whether funnelling by stemflow could reduce soil leaching by transmitting large volumes of water through vertical soil pathways beneath each stem.
