Applied Hydrology

Over the past 30 years, Brailey Hydrologic has completed appled hydrology projects for utilities, highways, mines, pipelines, energy projects, and other public and private developments.

 

Our approach focuses on developing robust and defensible data, models and designs. As an example, Brailey’s principals secured all of the required state, federal and local permits for the 300 kW Juniper Creek Hydroelectric Project in less than 18 months.

Groundwater

Brailey Hydrologic provides comprehensive groundwater monitoring and analysis services across Alaska, including infiltatrion testing, well installation oversight, water level monitoring, aquifer testing, and data interpretation.

 

We deploy vented and non-vented pressure transducers, and dataloggers to collect continuous groundwater level data in a wide range of site conditions. Monitoring programs are tailored to project needs and may include slug tests, pumping tests, and groundwater sampling for chemical analysis.

 

Data processing and interpretation are conducted to support hydrogeologic characterization, permitting, and long-term resource management.

Hydrologic modeling

Brailey Hydrologic provides advanced watershed modeling and hydrologic analysis using HEC-HMS to support flood forecasting, drainage design, and water resource planning.

 

Basin models are developed that can incorporate precipitation, infiltration, and runoff processes to simulate watershed response under a range of conditions. Model inputs are derived from high-resolution terrain data, land cover, and meteorological records, with calibration to observed streamflow where available.

 

Analyses include peak flow estimation, hydrograph development, and scenario evaluation for storm events and climate variability. Results are delivered through clear technical documentation and graphics to support engineering design, permitting, and decision-making.

Climate Change Analysis

Climate change impacts can be evaluated for watersheds and river systems using downscaled climate projections from published climate models.

 

We apply multiple emissions scenarios and time horizons to assess potential changes in temperature, precipitation, snowpack, and runoff timing. These projections can be integrated with hydrologic and hydraulic models to evaluate shifts in peak flows, baseflow conditions, flood frequency, and channel response.

 

Analyses are tailored to project needs and may include infrastructure risk assessments, habitat considerations, and long-term water resource planning. Results are presented through clear technical documentation and visualizations to support resilient design and informed decision-making under future climate conditions.
