Software Expertise
Pronounced
"Fish Crossing", FishXing is software designed to assist engineers,
hydrologists, and fish biologists in the evaluation and design of culverts
and other in-stream structures for fish passage. FishXing Version 2.2
is currently available and Version 3 is anticipated for the Spring of
2004.
Version
2 (released Nov 1999) allows for comparison of multiple culverts designs
within a single project. Hydraulic conditions are calculated for circular,
box, pipe-arch, open-bottom arch, and embedded culverts and compared to
fish swimming abilities. A database is available with swimming abilities
for numerous North American fish species. FishXing allows the user three
different options for defining tailwater elevations. Water surface profiles
including hydraulic jumps are calculated through the culvert using gradually
varied flow equations. Outputs are shown in tables and graphs summarizing
the water velocities, water depths, outlet conditions, and lists the limiting
fish passage conditions for each culvert.

Version 3
(currently in final completion stage) adds many new features. It allows
multiple side-by-side culverts at a single crossing site and hydraulic
criteria-based analysis. New culvert shapes are available including ellipse,
low-profile arch, high-profile arch, and metal box. The database of fish
swimming abilities has been greatly expanded and access to the user improved.
Hydraulic calculations now include adverse and no-slope culverts and pressurized
flow. Output has been greatly expanded with customizable output options.
Numerous flow characteristics are available over a range of flows and
through the length of the culvert. Image files can now be stored with
each crossing. There is even an animated re-creation of the fish’s
culvert negotiation
