Hydrology
Hydrologic Analysis & Watershed Studies
Rigorous, field-grounded hydrology for regulatory compliance, infrastructure design, and resource planning across the Black Hills and the West.
What Hydrology Covers
Hydrology is the foundation of every water resource decision. Anderson Water Consulting conducts comprehensive hydrologic analyses that quantify how water moves through a watershed — from precipitation and snowmelt through runoff, infiltration, and streamflow — providing the data your project needs to move forward with confidence.
Our work spans regulatory submittals, litigation support, infrastructure design, and long-range planning. Whether you need a flood frequency analysis for a bridge crossing or a full watershed model for a municipal water supply study, we bring the field experience and technical depth to deliver results that hold up under scrutiny.
Who Relies on Hydrologic Studies
- Municipal & County Engineers
- State & Federal Agencies
- Real Estate Developers
- Mining & Energy Companies
- Agricultural Operations
- Legal Counsel & Courts
Capabilities
What We Deliver
Watershed Delineation & Characterization
Precise mapping of drainage boundaries, sub-basins, and contributing areas using GIS, LiDAR, and field verification.
Flood Frequency Analysis
Statistical analysis of peak flows for return periods from 2-year to 500-year events, supporting bridge design, floodplain mapping, and FEMA submittals.
Stormwater Modeling
Rainfall-runoff modeling using HEC-HMS, TR-55, and rational method approaches for detention design, drainage studies, and permit applications.
Streamflow Analysis
Low-flow frequency analysis, flow duration curves, and baseflow separation to characterize available water and support instream flow determinations.
Drainage Assessments
Site-specific drainage evaluations for development projects, road crossings, and land use change — including pre- and post-development comparisons.
Regulatory & Litigation Support
Technical reports, expert testimony, and agency coordination for FEMA, Army Corps of Engineers, state engineer offices, and court proceedings.
