Biography
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.

Status: Active 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...

Status: Active 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...

Status: Active 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...

Status: Active 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...

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-...

Status: Active 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...

AbstractUsing observations from 688 debris flows, we analyse the hydrologic and landscape characteristics that influenced debris‐flow initiation mechanisms and locations in a watershed that had been partially burned by the 2012 Whitewater‐Baldy Complex Fire in the Gila Mountains, southern New Mexico. Debris flows can initiate due to different...

Estimating post-fire debris-flow hazards prior to wildfire using a statistical analysis of historical distributions of fire severity from remote sensing data
Following wildfire, mountainous areas of the western United States are susceptible to debris flow during intense rainfall. Convective storms that can generate debris flows in recently burned areas may occur during or immediately after the wildfire, leaving insufficient time for development and implementation of risk mitigation strategies. We...
