To understand the potential effects of proposed management solutions in the Bertrand Creek watershed, we used spatially distributed surface water quantity modeling.   Read the project assessment, a collaborative effort of STS, HydroLogic Services Co, the Nooksack Tribe, the Lummi Nation, the State of Washington Depr. of Ecology, and Utah State University.  Click here to download the report.

For the Water Resource Inventory Area 1 (WRIA1) Watershed Management Project to address the flooding issues in Fishtrap Creek, a good representation of the hydrologic system was required.  Using a historic climate record of 60 years, the simulated water balance illustrated how precipitation, soils, soil moisture recharge, and surface runoff are distributed in the catchment area.  Click here to download the report.  Read more about WRIA1. 

Dramatic changes to the land surface usually leads to dramatic changes in surface water runoff and groundwater recharge.  A data-based water budget comparing forested conditions with proposed urban development have been used in various applications to defend protecting natural and water resources in western Washington legal cases.  Contact us for representation and sample documents.

Instream Temperature in the Virgin River has been a topic of study for a number of years because of endangered native fish species in this extremely hot and dry river system.   Studies of energy balance components necessary to capture temperature fluctuations are available in The Journal of Hydrology and Hydrologic Processes. 

In cooperation with scientists at the USGS EROS Center and with support from USAID, Flood Forecasting for the Famine Early Warning System was implemented.  This hydrologic modeling system monitors wide-area hydrologic events with the use of geospatial and time series data in near-real time and is operational in countries throughout the world.  Download the technical manual here.  

Storm water runoff and urban development is a source of environmental and health hazards.  The cumulative effects of development over long-time periods has only begun to be implemented by policy. Contact us for representation and sample documents used in previous legal cases.

Physically based hydrologic modeling allows decision makers improved access to information and resources by integrating inputs and outputs at relevant locations and time-scales. For a sample report used to couple water-quantity modeling to support water quality improvement and planning, click here.
