• Setting & Research

  Spring Brook is in the Brandywine Conservancy's Laurels preserve and  is the CRB-CZO's forest endmember.  It is a ~8 ha 1st-order catchment that is 100% in mature forest.

  During Hurricane Irene in August 2011, the catchment showed only a ~2 cm increase in stream stage during six inches of rain.  Adjacent streams, with headwaters in pasture, all flooded overbank during Irene, leading CRB-CZO scientists to question whether geology or land cover is responsible for the tiny storm response in Spring Brook.

  Four soil pits (~1.0-1.5 m deep) have been dug along a hillslope transect. CRB-CZO is planning on intensively instrumenting this watershed in the near future. Currently there is a minimum of hydrological infrastructure. However, in the next 12 months we hope to install an H-flume for stream discharge and shallow wells for riparian groundwater elevation.

  Forest endmember geology

  The lithology of Spring Brook is mapped as uniform Laurels Schist, a silvery-gray-green quartz-plagioclase-muscovite-chlorite-garnet schist having minor biotite.

• Topography

  80 - 154 m elevation (131 m mean)

  Elevation data are based on 10m DEM data from USGS National Elevation Data.
