The Upland and Channel Network Modeling Research Group focuses on the development of state-of-the-art modeling tools for the integrated simulation of watershed and channel processes. This group has developed the CCHE1D channel network model, which is designed to be integrated with the watershed models, such as AGNPS, SWAT and WEPP. In the near future, the developed integration techniques will be applied in the integration of CCHE2D and CCHE3D channel models with watershed models.

Research Goals

The Upland and Channel Network Modeling Research Group has the mission:

Develop and enhance the channel network model, CCHE1D.

Develop and improve the techniques for the integration between channel (network) model and watershed models.

Apply the developed modeling tools in TMDL and BMP analyses, erosion and sedimentation control, environmental quality enhancement, etc.

Research Activities

The current research interests are focused on the following areas:

Landscape Analysis
Channel Network Flow Modeling

Software

CCHE1D
CCHE1D is a software package for the simulation of one-dimensional unsteady flow, sediment transport and water quality in dendritic channel networks. The software package has been designed to facilitate the combined modeling of watershed and channel processes.
