Program Officer, New Mexico Water Science Center
Anne Tillery has been a hydrologist in the Investigations section of the New Mexico Water Science Center since 2007. She holds a Master of Science in Earth and Planetary Science and a Bachelor of Science in Geology. She has 15 years of experience in surface water and geomorphic processes of the southwest. Her research focuses on the hydrology, hydraulics, and geomorphology of flooding in desert ephemeral channels and of debris flows following wildfires. She is currently the project chief for the Flood Analysis program in New Mexico. She conducts pre- and post- wildfire debris flow hazards assessments and documents postwildfire flooding and debris flows around New Mexico. Ms. Tillery has published studies related to postwildfire flooding and erosion, desert ephemeral-channel flow, and Holocene climate change impacts on desert geomorphology in addition to maps of stream networks and ground water levels.

Implementing a Web-based Streamflow Statistics Tool for New Mexico (StreamStats)
Estimates of streamflow are needed for a wide variety of applications, including water-resources planning and management, flood-plain mapping, and instream flow determinations. Surface water is the primary source of water for irrigators along major stream corridors in New Mexico and is increasingly being utilized by large municipalities. While streamflow statistics for gaged sites are readily...
Changes in Watershed Hydrologic Response Time with Post-wildfire Changes in Vegetation and Surface Fuels Along a Severely-burned, High-desert Canyon, Bandelier National Monument, NM
Flash flooding can be a destructive and life-threatening response of watersheds to intense rainfall events, particularly in sparsely vegetated, or burned watersheds. Studies have been conducted to estimate the magnitude of hydrologic responses of burned watersheds to rainfall events, however the time that it takes a flood to travel through a burned watershed and reach a critical or populated area...
Prewildfire Assessments of Postwildfire Debris-Flow Hazards
Debris flows are high-density slurries of water, rock fragments, soil, and mud that can have enormous destructive power. Wildfire can drastically increase the probability of debris flows in landscapes that have otherwise been stable. In 2010, the USGS developed the Cannon model to estimate postwildfire debris-flow probabilities and volumes in burned areas. In 2013, with the help of U.S. Forest...
Debris flows and Floods from Extreme Precipitation in September 2013, Gila National Forest, NM
A record-breaking rainstorm in Glenwood, New Mexico and the surrounding areas occurred in September, 2013 leading to widespread and destructive flooding and debris flows, including watersheds burned the previous year by the Whitewater-Baldy Complex wildfire. In the area of the Whitewater-Baldy burn scar, a highway was overtopped by flash flooding on Whitewater Creek. Many side canyon tributaries...
Postwildfire Debris-Flow Hazards
Wildfire is a natural process in forest ecosystems, and occurs with varying frequencies and severities depending on landscape characteristics, climatic conditions, and the historical fire regime. Although attention often is focused on the potential damages from wildfire in the wildland-urban interface, wildfire also presents a threat to critical infrastructure including flood water conveyances and...
Bandelier National Monument Postwildfire Flood Support
In the summer of 2011, the Las Conchas Fire burned 156,593 acres in the Jemez Mountains in northern NM including the upper watersheds of Frijoles and Capulin Canyons in Bandelier National Monument. The drastic removal of vegetation in the upper watersheds of these popular tourist destinations left them susceptible to dangerous and record breaking floods. As long as the threat of large post...
Floods Analysis
Accurate estimations of flood discharges at bridge or culvert sites is required to provide cost-effective design of that structure. Streamflow-gaging stations, for which flood data are available, are usually located in major perennial drainage basins that are not representative of sites where common bridge and culvert designs are needed.In 1942, the USGS, in cooperation with the New Mexico...
Analysis of the Magnitude and Frequency of Peak Discharge in the Navajo Nation and Surrounding Region, Arizona, Utah, Colorado, and New Mexico
Estimates of the magnitude and frequency of peak discharges on unregulated streams at gaging stations or ungaged stream sites in the Navajo Nation in Arizona, Utah, Colorado, and New Mexico are necessary for flood hazard mapping.
