Selecting Hydrodynamic and Water Quality Modeling Software
The modeling software you select for your project depends on project objectives, budget, schedule, and available programming resources.
Sigma-Zed Model in EFDC+
DSI has developed an improved version of the EFDC code to help deal with pressure gradient errors that occur in simulations that have steep changes in bed elevation. This new version of the code is called the Sigma-Zed code (SGZ) and has been integrated into the EFDC+
Simulating Hydraulic Structures in EEMS
Simulating hydraulic structures in hydrological and hydraulic calculations is crucial for ensuring the accuracy, safety, and sustainability of water resource management and infrastructure development projects
Single-layer vs. Multi-layer Simulations in Hydrodynamic and Water Quality Modeling
The selection of a single layer vs. multiple layers for simulating hydrodynamic and water quality depends upon a range of factors.
