Roanoke River Basin Model

Model Development Project Launch

The North Carolina Division of Water Resources has launched the hydrologic model development project for Roanoke River basin. The project kickoff meeting was held in Henderson, NC on August 23, 2012.

Need for a Hydrologic Model

The Roanoke River basin covers 9,580 square miles of total drainage area, 3,503 square miles entirely within North Carolina.  The basin supplies water to the population of nearly 344,638 people residing in 19 North Carolina counties within the basin.  

A computer model is a needed tool for evaluating surface water resources management in the basin.  For long term planning, the State can use the model in making regulatory decisions by evaluating potential impacts of proposed projects with significant water withdrawals within the basin as well as interbasin transfer permit applications.  Local units of government as well as the State can use the model to plan for increased water use due to growth, and to evaluate the effects of operational and regulatory constraints during a drought condition.


OASIS, a patented, mass balance, water resources simulation/optimization model will be developed for the Roanoke river basin. This basinwide model will use the finest practical geographic resolution and timestep.
