EFDC_DSI is a significantly enhanced version of the original EFDC code developed at VIMS. Enhancements made by DSI include dynamic memory allocation, particle tracking, water quality and sediment transport updates, and a host of other improvements.
EFDC_SGZ is the most recent major advancement to EFDC. This version significantly reduces the pressure gradient errors in stratified systems by allowing varied layer counts throughout the model domain.
efdc+ will be integrated into every paid version of EFDC_Explorer beginning with EFDC_Explorer8. Our goal is to release the new modeling system by March 1st.
Our goal with this change is to make sure we are providing everyone with the best product we possibly can. This means focusing on a single model for development and making sure it is the best we can offer.
