Solving real-world problems through innovation
Follum Hydrologic Solutions (FHS) helps water managers, infrastructure owners, and public agencies solve complex water-resource problems using hydrologic and hydraulic modeling, geospatial analysis, and purpose-built computational tools.
Our team combines decades of experience in water resources engineering, applied research, and operational decision support. We specialize in problems where data are limited, systems are complex, or conventional approaches are not enough; turning available information into practical, defensible solutions for planning, operations, design, and investment decisions.
Our work spans western water management, irrigation and conveyance systems, flood risk and inundation mapping, river and reservoir modeling, GIS and remote sensing, hydroinformatics, and independent technical review.

Snow and Frozen Ground Simulations
Water from the snowpack drives the rivers in for much of the World and can be a large contributor to flooding. Historically, snow has been difficult to simulate due to limited data availability for both forcing and calibrating the numerical methods.
