Modeling Tropical Cyclones in EEMS
A tropical cyclone is a system of rapidly rotating wind around a low-pressure center that produces extreme winds, gusts, and heavy rainfall.
Hydrodynamics
Movement of Lagrangian Particles across Hydraulic Structures
The Lagrangian Particle Tracking (LPT) module in EFDC+ was developed by DSI in 2009 and has served as an effective tool for solving numerous problems in fluid dynamics.
Navigating Vertical Layering in EFDC+: A Comprehensive Guide
EFDC+ is a versatile hydrodynamic model capable of operating in 1-, 2-, or 3-dimensional (3D) modes. For 3D simulations, EFDC+ allows users to choose from two vertical layering schemes
Partial Depth Flow Blocking - Part 1
DSI has added a new capability to EFDC+ 10.1. This new capability allows the model to simulate partially blocked depths due to floating objects
Partial Depth Flow Blocking - Part 2
Lake Washington is a very deep lake that made conventional bridge construction difficult. To allow a traffic to cross the lake, a floating bridge was constructed.
Propwash Mixing of a Hypersaline Bottom Layer
A 3D EFDC+ simulation showing how propeller wash from passing ships breaks up a 100 ppt hypersaline bottom layer in a navigation canal.
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
Simulating Wind-Induced Waves in EEMS
High wind speeds associated with hurricanes are capable of producing extreme waves, and high winds, currents, and tides can combine to create storm surge.
The History of Hydrodynamic Studies
This is the first in a three-part blog series that provides an introduction to hydrodynamic modeling, an overview of how models work, and, finally, an exploration of their many applications.
The Importance of Propeller Wash Modeling
Many urban waterfronts are contaminated with metals, petroleum hydrocarbons, and other organic chemicals, often as deep as 20 feet within the sediment bed.
Transforming Node Time Series Model Result to EE Field File
In many situations, a modeler may need to incorporate results from an external model into an EFDC+ model.
Using Multiple Wind Series in EEMS
Wind is an essential factor in hydrodynamic model settings. EEMS has a feature that allows users to add multiple wind series to the model.
Validation of New Jet and Plume Features in EEMS
In a recent blog, we highlighted some of the recent enhancements to the jet and plume features in EEMS.
Webinar: Increasing the Performance of EFDC+ Models using Domain Decomposition
EEMS 10.2 includes EFDC+ with domain decomposition and Message Passing Interface (MPI) to significantly improve the model performance.
Velocity Profile of a Propeller Moving Through a Channel
In our propeller wash (propwash) blog series, we have shared details of the propwash simulation feature that will soon be available in the upcoming version of EEMS.
