PROJECTS

Refer to our interactive map on the home page for a full listing and description of our projects.  Some project examples that showcase our range of expertise are listed below. 

Drought Management -- Rocky Mount, NC
This project in the early 1990s resulted in our first application of forecast-bsed drought triggers for the municipal water supply business.  This landmark application allowed the city to reliably navigate droughts while postponing indefinitely a planned $70 million capacity expansion.   Read more...
Roanoke River Projects -- VA/NC
HydroLogics played a major role over the last three decades in the adaptive management of the river, which is one of the most ecologically significant in the United States. Our work included modeling the system of reservoirs, applying our computer-aided negotiation to resolving mult-objective conflicts, assisting in the relicensing of hydropower projects, and setting OASIS up for real-time energy dispatch for Dominion Power and implementation of low flow protocols for Appalachian Power, the first forecast-based protocol in a hydropower license.  Read more...
Flood Control Forecasting -- West Point Reservoir, GA
This project demonstrated a technique for incorporating forecasts into operating rules for use in managing flood flows from the reservoir.  The rules reduce the peak flood flows by about 15% compared to either historical performance or simulation of existing rules. This performance increase could alternatively maintain the current level of flood protection while dynamically making additional storage available for other purposes, a concept that significantly enhances the dynamic allocation typically done using rule curves.

Operations Support Tool (OST)-- New York City, NY
HydroLogics worked with a team led by Hazen and Sawyer engineers to develop the OST, which is hailed as a "first of its kind" reservoir modeling system that has allowed the city to increase its water supply reliability while avoiding spending $300 million on a new reservoir intake.  The OST uses a system of databases and customized OASIS and water quality models that incorporates real-time data, statistical and meterological forecasts, and computer simulation to guide both daily and long-term reservoir operations decisions.  Read more...
Collaborative Modeling - South Saskatchewan River Basin, Canada
Over multiple river basin projects, ultimately leading to a mega-system model, our work led to collaborative modeling  for integrated water resources management across southern Alberta. The innovative work included development of forecast-based flood control operations, optimization of hydropower revenue including ancillary services, and development of non-stationary hydrology based on climate forecasts of sea surface temperature anomalies.  The projects were instrumental in the new agreement between the Government of Alberta and the power utility to utilize existing hydropower storage to mitigate future flooding along the Bow River in Calgary and other nearby areas.  Read more...
Dynamic Reservoir Operations  - Potomac River Basin, Washington D.C Metro Area
HydroLogics staff have long had a role in shaping water policy in the D.C. area.  Dan Sheer, founder of HydroLogics, was formerly the director of the Cooperative Branch of the Interstate Commission of the Potomac River Basin and helped craft operating agreements to provide a 30 percent increase in yield.  Recent work by HydroLogics focused on the resilience of this and other systems to climate change, resulting in a Water Research Foundation report on the value of dynamic reservoir operations.  Read more.....
Regional Water Analysis - Las Vegas, NV
HydroLogics (known as WRMI at the time) developed the collaborative modeling process (known regionally as the WRMI process) and the models that were instrumental in the formation of the Southern Nevada Water Authority in 1991. The process was widely seen as the last alternative to court action and led to an agreement between five regional water authorities to coordinate their operations and water supply development planning  under an umbrella authority.
