Michelle is a hydrologist at the USGS California Water Science Center in Sacramento, CA.
Her research focus is on climate change and soil moisture as key processes of watershed and regional-scale hydrologic modeling. Other research interests include geospatial analysis and sediment transport. She has also performed extensive laboratory work determining physical properties of soil samples and sediment cores. Current research includes refining and applying the Basin Characterization Model (BCM), and the development of an Hydrologic Simulation Program - FORTRAN (HSPF) model of the Sacramento River basin to determine future sediment supply to the Bay-Delta as part of the Computational Assessments of Scenarios of Change for the Delta Ecosystem (CASCaDE) project. A key goal of all her research is to determine a holistic understanding of watershed hydrologic processes at different spatial scales.

New Technologies for Mapping Surface Soil Moisture Over Wildfire-Prone Landscapes
A partnership between the USGS, Pepperwood Preserve, and Black Swift LLC aims to map soil and fuel moisture over wildfire-prone landscapes.
Improving Water Resilience and Availability Through Cultural Prescribed Fire as a Management Tool on Yurok Tribal Lands
Climate Change is making our environment unpredictable. Increased persistence of drought is causing deaths of plants and animals across our landscapes. However, drought amongst the western United States is not a new thing. Native American populations have been living with drought since time immemorial and practiced culturally prescribed fire practices to foster the landscape for an environment tha
Sediment transport, streamflow, and climate change: long-term resilience of the Bay-Delta
Sediment supply is important to the health of the Sacramento-San Joaquin River Delta and San Francisco Bay (Bay-Delta) ecosystem. Sediment eroded from upland source areas in the Sacramento and San Joaquin watersheds is transported through the rivers to the Bay-Delta where it is deposited in mudflats and tidal wetlands, which in turn helps protect against the effects of sea-level rise. Sediment...
Soil moisture datasets at five sites in the central Sierra Nevada and northern Coast Ranges, California
Soil moisture is a critical variable for understanding the impacts of drought on ecological, hydrological, and agricultural systems, as soil moisture content has a direct affect on runoff amounts. Runoff occurs as the result of precipitation (both rainfall and snowfall) that is in excess of the demands of evaporation from land surfaces, transpiration from vegetation, and infiltration into soils...
Researching Climate Conditions for CAL FIRE Wildfire Restoration Efforts
In California, drought and warmer climates have increased the prevalence, severity, and duration of wildfires. These fires have destroyed over 129 million trees. In the aftermath of this devastation, there is heightened urgency to increase the capacity of seedling production, particularly for the lower-elevation and private lands that CAL FIRE is responsible to help manage. To support CAL FIRE in...
Basin Characterization Model (BCM)
The Basin Characterization Model (BCM) is a simple grid-based model that calculates the water balance for any time step or spatial scale by using climate inputs, precipitation, minimum and maximum air temperature. The BCM can translate fine-scale maps of climate trends and projections into the hydrologic consequences, to permit evaluation of the impacts to water availability at regional, watershed...
Increasing Soil Organic Carbon to Mitigate Greenhouse Gases and Increase Climate Resiliency for California
Rising air temperatures are projected to continue to drive up urban, agricultural, and rangeland water use, straining both surface and groundwater resources. Scientific studies have shown that managing farms, ranches, and public lands to increase soil carbon can increase soil waterholding capacity and increase hydrologic benefits such as increased baseflows and aquifer recharge, reduced flooding...
