Summary
Floodplain surficial soil samples (10 cm depth) were collected from 18 streams in the urbanized Piedmont region of northern Virginia, representing a chronosequence of time (1-10 yrs.) since stream restoration as well as unrestored and reference streams. The samples were analyzed for total carbon (TC), total nitrogen (TN) and total phosphorus (TP) storage, whereas CO2 mineralization potential and equilibrium phosphorus concentration (EPC0) were measured as metrics of nutrient and carbon loss. Samples also were analyzed for soil moisture, pH, particle size, organic matter content, and degree of phosphorus saturation.

Purpose
The goal of the study was to determine how floodplains change in their phosphorus, nitrogen, and carbon storage and release as the result of stream restoration. Soil nutrient and carbon retention metrics can be compared to the time since restoration and to soil characteristics.
