Summary
This product releases data on soil physical and hydraulic properties in the area affected by the 2011 Las Conchas Fire in New Mexico, USA. Soil samples were collected in the summer of 2015 to assess the state of the watershed following the 2011 wildfire. Data include soil-hydraulic properties of field-saturated hydraulic conductivity and sorptivity from tension infiltrometer measurements on soil cores. Soil physical properties include bulk density, as-sampled volumetric soil-water content, and saturated volumetric soil-water content for 6-cm length soil cores. Soil properties of soil-particle size, bulk density, and soil organic matter content from loss on ignition for soil core splits of 0-1. 1-3, and 3-6 cm depth. Photographs of [...]
Summary
This product releases data on soil physical and hydraulic properties in the area affected by the 2011 Las Conchas Fire in New Mexico, USA. Soil samples were collected in the summer of 2015 to assess the state of the watershed following the 2011 wildfire. Data include soil-hydraulic properties of field-saturated hydraulic conductivity and sorptivity from tension infiltrometer measurements on soil cores. Soil physical properties include bulk density, as-sampled volumetric soil-water content, and saturated volumetric soil-water content for 6-cm length soil cores. Soil properties of soil-particle size, bulk density, and soil organic matter content from loss on ignition for soil core splits of 0-1. 1-3, and 3-6 cm depth. Photographs of each sampling site and the coring locations are also included in the data set.
Note that this Data Release was later revised to correct formatting issues and an error in the calculation of portions of the field-saturated hydraulic conductivity and sorptivity estimates from tension infiltrometer measurements, specificall the Cumulative Infiltration method analysis.
Changes to files:
The depth range format was changed from “0-1”, which denoted the depth range of the sample in cm, to “0_1”. For example, a sample taken from 0-1 cm depth was “0-1” in the previous files and is now “0_1”. The reason for this change is that certain software (Microsoft Excel) would automatically read in the depth ranges as dates. For example, “1-3” became January 3. The new format prevents this issue.
This change applies to files:
All_BulkDensity_splits.csv
All_LOI_Data_splits.csv
LasConchasParticleSize.csv
The second change was to correct the Cumulative Infiltration method values for field-saturated hydraulic conductivity and sorptivity. This change was needed because of a numerical formula error. The Cumulative Linearization and Differentiated Linearization methods were not affected.

This product releases data on soil physical and hydraulic properties in the area affected by the 2011 Las Conchas Fire in New Mexico, USA. Soil samples were collected in the summer of 2015 to assess the recovery of the watershed following the 2011 wildfire. The purpose of this data is to investigate the duration and magnitude of post-wildfire flooding.
