Overview
• Six soil moisture monitoring sites in the Babocomari River Basin
• Soil moisture and temperature at standard NRCS depths (5, 10, 20, 50, 100 cm)
• Surface air temperature and relative humidity• Tipping Bucket Rain Gages• Two minute temporal resolution transmitted to Boulder
hourly

Babocomari River Flood 23 July 2008
• Second highest discharge measured on the river in the period of record
• First flood event captured by the HMT network

Meteorological Setting• Typical monsoon
upper air pattern consisting of a ridge over the four corners region
• No dynamic forcing• Significant
Convective Instability• CAPE= 2768 J/kg• LI= -4.77• Precipitable
Water= 52.52mm

Soil Moisture ResponseLower Basin (WSE) 50 cm Caliche
• HMT Network data indicates that the lower Babocomari basin was saturated before the flood
• The upper basin had lower soil moisture values• Significant streamflow response in the lower Babocomari River
Upper Basin (FMS) 100 cm Caliche

Soil Moisture DifferencesNoah LSM Level 1 and HMT 5 cm:
• Noah LSM soil moisture values show dry bias in the lower basin• Wet bias in upper basin, seen at both ELG, and FMS
Noah LSM Level 2 and HMT 20 cm:
