Hydraulic Considerations for Pipelines Crossing Stream Channels

In 2002, the U.S. Fish and Wildlife service raised concerns about the potential for flash floods in eperneral stream channels to rupture natural gas pipelines and carry toxic condensates to the Green River, which would have deletrious effects on numerous special- status fish species. In November of the same year, BLM hydrologists visited the Uinta Basin in Utah to Survey stream channels and compute flood magnitudes and depths to better understand possible flooding scenarios.
