NC DEQ-DWR Neuse River Basin Model
|Neuse River Basin Model
Model Development Project Launch
North Carolina Division of Water Resources has launched the hydrologic model
development project for Neuse River basin. Project kick off meeting was held in
Raleigh, NC on February 25, 2008.
Need for a Hydrologic Model
The Neuse basin covers 6235 square miles of drainage area entirely within
North Carolina. The basin supplies water to the population of nearly 1.4 million
residing in 22 counties within the basin up and downstream of the Triangle, one
of the state's fastest growing areas. Ground water is a major source of water
for the communities in the coastal plains in this basin. However, the Piedmont
area of the basin mostly relies on surface water withdrawn from the lakes or
directly from the river, which represents the two thirds of the total demand in
A computer model is a needed tool for this surface water management purposes.
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 and interbasin transfer permit application,
planning for increased water use due to continuous growth, and in real time in
managing the basin having challenges of resources, and operational and
regulatory constraints during a drought condition.
OASIS, a patented, mass balance, water resources simulation/optimization model
will be developed for the Neuse river basin. This basinwide model will use the
finest practical geographic resolution and timestep.
