The Engineering Computer Graphics Laboratory of Brigham Young University specializes in computer graphics programs for pre and post processing of watershed, surfacewater, and groundwater modeling. Partnering with the U.S. Army Corps of Engineers Waterways Experiment station ECGL has performed research and development of three popular software programs for engineering analysis. The BYU module contains the following:
WMS
(Watershed Modeling System) was described in GIS Hydro '97 and this year's
update includes information on a new extension to ArcView which facilitates
the movement of data from your GIS to WMS for hydrologic model development.
Another important addition to the latest version of WMS is a new time of
concentration calculator which uses digital terrain data and flow path
arc segments to define/evaluate equations such as those used in TR-55 and
the FHWA. This module was prepared by Dr
Jim Nelson of the Dept. of Civil and Environmental Engineering of BYU.
GMS
(Groundwater Modeling System) was also included in the GIS Hydro '97 and
includes updated information on an improved map module which links GMS
to ArcView by using coverages to define groundwater modeling domains and
boundary conditions. GMS remains the state of the art in groundwater modeling
development by continuing to enhance the MODFLOW interface with a new interface
to RT3D. This module was prepared by Dr
Norm Jones of the Dept. of Civil and Environmental Engineering of BYU.
SMS
(Surface-Water Modeling System) uses the same map module for linking to
ArcView as WMS and GMS. It is a new inclusion to GIS Hydro '98 and describes
how GIS layers can be used to develop finite element and finite difference
models including boundary conditions for popular 2D surface water models
such as RMA-2 and FHSWMS. This module was prepared by Dr
Alan Zundel of the Dept. of Civil and Environmental Engineering of
BYU.
