Results from a preliminary sampling program designed to investigate total (THg) and methyl Hg (MeHg) deposition, cycling and transport at the Coweeta Hydrologic Laboratory western North Carolina are presented. Wet deposition samples were collected in June and July 1994 and throughfall, seep and streamwaters were intensively collected during and after a rainfall event in June 1994. All water sam...

Crops are one of the main factors affecting soil erosion in sloping fields. To determine the characteristics of splash erosion under crop canopies, corn, soybean, millet, and winter wheat were collected, and the relationship among splash erosion, rainfall intensity, and throughfall intensity under different crop canopies was analyzed through artificial rainfall experiments. The results showed t...

MUNISHI, P. K. T. & SHEAR, T. H. 2005. RainfaU interception and partitioning in afromontane rain forests of the Eastern Arc Mountains, Tanzania: implications for water conservation. The aboveground components of the hydrologic cycle of rain forest are important processes that determine the hydrologic hehavioiir and dynamics of these ecosystems. Precipitation, throughfall, stem flow, canopy inte...

Sulfate (SO4(2-)) concentrations and fluxes were studied for multiple storm events in the Point Peter Brook watershed, a glaciated, forested watershed located in Western New York, USA. Investigations were performed across one large (696 ha) and three small (1.6-3.4 ha) catchments with varying extent of riparian and wetland areas. Concentrations of SO4(2-) in groundwater sources (mean values: 23...

The first measurements of Sr isotopic composition and concentration of archived stream water samples from the Hubbard Brook Experimental Forest in central New Hampshire were collected to evaluate long term trends. The presented data are for two watersheds, one of which was timber harvested in late 1983, and the other is a control watershed. Excess anion deposition, deforestation, and drought ar...

Atmospheric rainfall is one of the major sources water and nutrient inputs in forest stands. Understanding atmospheric partitioning hydrochemical fluxes stands critical for management monitoring regional pollution, especially high N deposition regions. In this study, annual collections were implemented to investigate partitioning, element concentrations, an evergreen coniferous (ECF) stand, a d...

Abstract Tree-derived dissolved organic matter (DOM) comprises a significant carbon flux within forested watersheds. Few studies have assessed the optical properties of tree-derived DOM. To increase understanding factors controlling DOM quality, we measured properties, (DOC) and calcium concentrations in throughfall stemflow for 17 individual rain events during summer fall temperate deciduous f...
