NEON Soil Preferential Flow Database

Preferential flow in soil important in supporting water and nutrients transportations. We derivate a preferential flow database using multi-depth soil moisture and precipitation measurements in NEON sites. The database contains water flow velocity for each precipitation event for any given sensor, site characteristics, soil characteristics at each sensor depth etc. The v1.1 expands the last version by incorporating different Ksat estimates from Rosetta as a threshold for velocity thresholding method for identifying preferential flow. Please also be noted that sites in Alaska {"BONA", "DEJU", "HEAL", "TOOL", "BARR" } are not recommended to use. Additionally, "KONA" is not include in our analysis, as it is closer to "KONZ".
