Site Info:

The Site Info Window contains information about the crossing including site description, latitude and longitude, and photos. You can also change the units between English and metric for the crossing file here.

Fish Information:

Fish performance and passage criteria are determined from swim speed data or hydraulic criteria. Select from swim speed data derived from scientific literature, enter your own swim speed data, and define hydraulic conditions required for passage.  More about Fish Information.

Culvert Information:

Culvert shape, material, dimensions, and placement.  Includes reference tables for complex culvert shapes, entrance coefficients and roughness factors. More about Culvert Information.

Velocity Reduction Factors:

Velocity Reductions Factors used to account for fish swimming against water flowing slower than the calculated average cross sectional velocity.

Fish Passage Flows:

Low and High Fish Passage Flows define the range of flows that fish passage is required.  FishXing analyzes passage conditions throughout this range of flows.

Tailwater:

Water surface elevation immediately downstream of the crossing is defined using one of three methods. The tailwater elevation changes with flow, affecting the culvert outlet hydraulics and fish passage. More about Tailwater Methods.
