IDRC Regional Watershed Historical Weather Study Town Brook, NY, USA

Town Brook watershed, Catskills, New York. SWATWB was also tested on the Town Brook watershed (Figure 2) in the USA, a 37 km2 sub-catchment of the Cannonsville reservoir basin. The region is typified by steep-to-moderate hillslopes of glacial origins with shallow permeable soils, underlain by a restrictive layer. The climate is humid with an average annual temperature of 8 ¢XC and average annual precipitation of 1123 mm. Elevation in the watershed ranges from 493 to 989 m above mean sea level. The slopes are quite steep with a maximum of 91%, and a mean of 21%. Soils are mainly silt loam or silty clay loam with soil hydrological group C ratings (USDA–NRCS, 2000). Soil depth ranges from less than 50 cm to greater than 1 m and is underlain by a fragipan restricting layer (e.g. coarse-loamy, mixed, active, mesic, to frigid Typic Fragiudepts, Lytic or Typic Dystrudepts common to glacial tills) (Schneiderman et al., 2002). The lowland portion of the watershed is predominantly agricultural, consisting of pasture and row crops (20%) or shrub land (18%), whereas the upper slopes are forested (60%). Water and wetlands comprise 2%. Impervious surfaces occupy <1% of the watershed and were thus excluded from consideration in the model. Several studies in this watershed or nearby watersheds have shown that VSAs control overland flow generation (Frankenberger et al., 1999; Mehta et al., 2004; Lyon et al., 2006; Schneiderman et al., 2007; Easton et al., 2008) and that infiltration-excess runoff is rare (Walter et al., 2003). This is an example dataset to be used as a template as well as demo for NSF BCube Brokering project, and as such it is subject to change.
