Using ArcGIS to map watersheds
Flood Plain Maps and Alluvial Soils of the Preston Brook Watershed
Flood Plain Maps and Alluvial Soils of the Preston Brook Watershed Looking at data for the Preston Brook watershed, it is quite a small shed, so I decided to analyze data from the surrounding larger Winooski River watershed that Preston Brook feeds into. Typical soils in the Winooski River watershed are deep, moderately well drained, and formed in alluvial materials. These soils are fairly coarse and silty, which makes them have fine drainage capabilities. The following image represents that USDA Soil Survey data for soil types in the Winooski River watershed…as we can see, the soils are primarily Adams and Windsor soils, which are loamy-sand soils (nice for drainage!). The history of soils in Vermont as a whole is actually quite interesting! The soil in the Champlain valley region of Vermont (and the Preston Brook watershed) are relatively young, as the glaciers that covered the state receded only about 13,500 years ago ( Burlington Geographic).
