  • Abstract:
    The subsurface hydrology of vernal pools at three vernal pool complexes was investigated during three wet seasons in 2002- ; 2004. The complexes were at Gridley Ranch, Valensin Ranch, and the Mather Field in northern California. The selected ; complexes provided variation in soils, landforms and topography. Three vernal pools were chosen in each complex based ; on variation in pool type, size, and position in the drainage system. The objectives were to describe the subsurface ; hydrology of vernal pools to refine the conceptual model of vernal pool hydrology and to answer questions about: the size of ; watershed support for vernal pools, the importance of the watershed and drainage system to the vernal pools, the possible ; effects of truncating the watershed or eliminating upstream pools, the potential role of perched aquifers, and subsurface ; connections among pools, in controlling the length of inundation. The vernal pools studied demonstrated markedly different ; hydrologic behaviors due to variation in topography and soil properties near the pools. The hydrologic behavior of vernal ; pools has important implications for land use practices and for impact remediation efforts. Additional research is needed to ; refine our understanding of vernal pool hydrology.
