BACK Lake Washington Real-Time Model DSI recently developed a real-time model for Lake Washington, along with a public-access model portal. The portal allows users to view historical and current data on measured and simulated water levels, temperature, and velocity, presented in map view, time series, and vertical profiles. Users can also compare the data with…
BACK JSON Formatted Files in EEMS JSON (JavaScript Object Notation) is an increasingly common standard data format to store and transmit data objects that use text designed to be easily read by humans. JSON serves as a syntax for serializing objects, arrays, numbers, strings, booleans, and null. Although it is based upon JavaScript syntax, it…
BACK Enhancements to the EEMS GUI As we added new features to EFDC+, our Graphical User Interface (GUI), EFDC_Explorer (EE) has also changed to support these new features and capabilities. In this post, we describe three major changes in the GUI. Water Quality Interface With EFDC+’s new ability to simulate unlimited algal, macrophyte, periphyton, and…
BACK Modeling Interaction Between Phytoplankton and Zooplankton in EEMS Introduction Zooplankton population modeling is a significant new feature in the recently released version of EFDC_Explorer Modeling System (EEMS 10.3). Built as a sub-module of the Water Quality module, the new zooplankton feature is a first step toward modeling the effects of eutrophication on higher-level predators.…
There can be multiple reasons when a modeler needs to incorporate results from another model. It can be the lack of direct measurement of specific properties or…
This post introduces a simple testing process to demonstrate how the propeller wash module works with EFDC+’s sediment transport process modeling features.
The Network Common Data Form (NetCDF) data format was originally intended to create, access, and share array-oriented data in a form that is self-describing and portable…
Communicating your modeling results to a wide variety of audience is as important as developing a good model. Animating the processes is one of the most powerful ways in which a modeler…
Wind-induced waves affect the propagation of gravity waves. Wave modeling hindcast is a critical step for wave energy development and…
Water quality simulation in waterbodies involves the biochemical transformation of the nutrients, their movement through several water layers….
In this post, we would like to demonstrate how the propeller transfers the energy to the water column causing sediment resuspension.
Simulation of the impacts of propeller wash in hydrodynamic and sediment transport models requires detailed information on ship travel routes and the physical characteristics of each ship.
Many urban waterfronts are contaminated with metals, petroleum hydrocarbons, and other organic chemicals. The contamination could be as much as 20 feet…
Climate change is an accepted reality, so most infrastructure development and maintenance will require the evaluation of possible impacts of climate change.
