EEMS Feature: Partial Flow Blocking
Partial flow blocking was added as a feature of EEMS with version 10.1.
EFDC+/GOTM Scenarios: Free Convection
This blog discusses the results of a free convection test case performed with different turbulence closures available in EEMS 12.
EFDC+ GOTM Scenarios: Open Channel Flow
The choice of turbulence closure scheme has important consequences on model results through mixing and circulation (Burchard et al., 1998)
EFDC+ MPI Multi-core Scaling Study
In 2020, DSI implemented MPI in EFDC+ to improve model run time.
EFDC+ v10.2 MPI – Benchmark Test
To assess the performance of the Message Passing Interface (MPI) implementation with Environmental Fluid Dynamics Code Plus (EFDC+)
Enhanced Jet and Plume Features Coming to EEMS
Simulation of jets and plumes is an essential aspect of computational fluid dynamics. Jet and plume modeling is required in many natural and industrial applications
Equation-based Options in Hydraulic Structures
In our previous blog, we provided an overview of simulating hydraulic structures in EEMS, where we discussed the importance of rating tables and flow lookup tables in determining flow rates based on water surface elevations.
Estimating Ship Engine Power for EFDC+ Propeller Wash Simulations
Developing a propeller wash model requires specifying the ship and propeller properties as model input parameters.
Flow Lookup Tables in EEMS
In a recent blog, we provided an overview of simulating hydraulic structures in EEMS. As a continuation, this blog details the rating table/flow lookup table to help users understand the nuanced dynamics of hydraulic structure simulations
High-Resolution Marine Cadastre AIS Data for Propwash Modeling
Propeller wash (propwash) causes sediment scour in the seabed that can threaten the safety of structures in ports and harbors and cause environmental problems
Implementation of Domain Decomposition in EFDC+ Using MPI
A primary function of EFDC+ is to solve the governing Partial Differential Equations (PDEs) for fluid flow and constituent transport.
Implementation of Macrophyte Effects on Hydrodynamics in EFDC+
Submerged macrophytes are part of an essential relationship between the physical habitat and the biological community.
Lake Mead Sigma-Zed Application
Lake Mead is the largest reservoir in the USA, and 16th largest man-made lake in the world. Lake Mead is formed by the Hoover Dam along the Colorado River.
Lake Washington Sigma-Zed Application
Lake Washington is the second largest natural lake in the State of Washington, USA. It is a lake with steeply sloping sides and also has long-term
