Historical Roots of Forest Hydrology and Biogeochemistry

The scientific disciplines of forest hydrology and forest biogeochemistry have contributed greatly to our understanding of the natural world even though they are relatively young disciplines. In this chapter, the historical origins, developments, and major advancements of these disciplines will be presented. The Hubbard Brook Ecosystem Study (HBES) will serve as a case study to illustrate the d...

International Workshop ADVANCES IN STATISTICAL HYDROLOGY

Flood frequency analysis (FFA) entails estimation of the upper tail of a probability density function (PDF) of annual peak flows obtained from either the annual maximum series or partial duration series. In hydrological practice the properties of various estimation methods of upper quantiles are identified with the case of known population distribution function. In reality the assumed hypotheti...

EUROCONTROL Innovative Research Workshop 2007

Air traffic control systems display information using multiple visual variables. The research described in this paper is an initial effort to develop a theory-driven approach to the characterization of user interfaces. We will focus on the displayed visual object and deliberately leave aside the interaction. In this article, we depict the state of the art in data visualization, and we character...

Seasonal Isotope Hydrology of Three Appalachian Forest Catchments

Seasonal oxygen-18 variations in precipitation, throughfall, soil water, spring ̄ow and stream base ̄ow were analysed to compare the hydrology of two forested basins in West Virginia (WV) (34 and 39 ha) and one in Pennsylvania (PA) (1134 ha). Precipitation and throughfall were measured with funnel/bottle samplers, soil water with ceramic-cup suction lysimeters and spring ̄ow/base ̄ows by grab and...
