2006, Conference Paper, Proceedings of the iEMSs Third Biennial Meeting: "Summit on Environmental Modelling and Software"
There are inherent open problems arising when developing and running Intelligent Environmental Decision Support Systems (IEDSS). During daily operation of IEDSS several open challenge problems appear. The uncertainty of data being processed is intrinsic to the environmental system, which is being monitored by several on-line sensors and off-line data. Thus,...

Guy R. Larocque, Jagtar S. Bhatti, A.M. Gordon, N. Luckai, Jinxun Liu, Shuguang Liu, P.A. Arp, C.F. Zhang, A Komarov, P. Grabarnik, M. Wattenbach, C. Peng, Jianfeng Sun, Thomas White
2006, Conference Paper
Many process-based models on carbon (C) and nitrogen (N) cycles have been developed for northern forest ecosystems. These models are widely used to evaluate the long-term decisions in forest management dealing with effects like particulate pollution, productivity and climate change. Regarding climate change, one of the key questions that have...
Heat-producing elements in the lunar mantle: Insights from ion microprobe analyses of lunar pyroclastic glasses
Justin Hagerty, Charles K. Shearer, David Vaniman
2006, Geochimica et Cosmochimica Acta (70) 3457-3476
We provide new estimates for the abundance of heat-producing elements in the lunar mantle by using SIMS techniques to measure the concentrations of thorium and samarium in lunar pyroclastic glasses. Lunar pyroclastic glasses are utilized in this study because they represent quenched products of near-primary melts from the lunar mantle...

Regionalized equations for bankfull-discharge and channel characteristics of streams in New York State—Hydrologic Region 7 in western New York
Christiane I. Mulvihill, Anne G. Ernst, Barry P. Baldigo
2006, Scientific Investigations Report 2006-5075
Computation of bankfull discharge and channel dimensions (width, depth, and cross-sectional area) at ungaged sites requires equations that relate bankfull discharge and channel dimensions to drainage-area at gaged sites. Bankfull-channel information commonly is needed for watershed assessments, stream channel classification, and the design of stream-restoration projects. Such equations are most...
A system for calibrating seepage meters used to measure flow between ground water and surface water
Donald O. Rosenberry, Michael A. Menheer
2006, Scientific Investigations Report 2006-5053
A system has been developed for generating controlled rates of seepage across the sediment-water interface representing flow between ground water and surface water. The seepage- control system facilitates calibration and testing of seepage measurement devices commonly called seepage meters. Two slightly different seepage-control systems were evaluated. Both designs make use...
A thermal profile method to identify potential ground-water discharge areas and preferred salmonid habitats for long river reaches

Kamini Singha, Steven M. Gorelick
2006, Water Resources Research (42)
Direct estimation of groundwater solute concentrations from geophysical tomograms has been only moderately successful because (1) reconstructed tomograms are often highly uncertain and subject to inversion artifacts, (2) the range of subsurface conditions represented in data sets is incomplete because of the paucity of colocated well or core data and...
