Shallow water tables near-streams often lead to saturated, overland flow generating areas in catchments in humid climates. While these saturated areas are assumed to be principal biogeochemical hot-spots and important for issues such as non-point pollution sources, the spatial and temporal behavior of shallow water tables, and associated saturated areas, is(More)
Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract Spatial patterns of water chemistry along stream networks can be quantified using synoptic or " snapshot " sampling. The basic idea is to sample stream water at many points over a relatively short(More)
The historical spatio-temporal distribution of invasive species is rarely documented, hampering efforts to understand invasion dynamics, especially at regional scales. Reconstructing historical invasions through use of herbarium records combined with spatial trend analysis and modeling can elucidate spreading patterns and identify susceptible habitats(More)

G eographical information systems (GIS) are well suited for database collection and management related to geographically dispersed networks. Access to and management of GIS through the Internet allows for effective, multiuser development and applications of databases for lifeline and hospital systems; a platform for the dynamic assembly of data and rapid(More)
