Daniel Hirmas

Assistant Professor of Geography
Primary office:

Dr. Hirmas is a soil scientist with research interests in the characterization of soil morphology and the impact of soil structure on preferential flow. Key topics include: understanding the relationship between mineral dissolution, pedogenic carbonate, and hillslope hydrology; effects of soil architecture on hydraulic properties such as the transport of nutrients and dissolved inorganic carbon; relating lateral distributions of inorganic carbon, nitrate, and soluble salts to surface and near-surface properties; and using process-based modeling to predict landscape-scale hydraulic properties from the distribution of inorganic carbon. Most recently, Dr. Hirmas has pioneered the use of multistripe laser triangulation to scan the surface topography of soil aggregates and excavation walls to non-destructively measure soil properties such as bulk density, porosity, and roughness, and link soil architecture to the distribution of plant-available water.
