Modeling Not By the Numbers
A model is likely to be the tool for making predictions of the ecological impact of an engineering decision. However, ecologists often find it difficult under pressures of time and lack...
The Stacked Drift Tunnel
The Mount Baker Ridge Tunnel is the first of its kind and the last: a forward thrust of technology and a look back to the flow of federal highway funds, which paid 90% of its cost. The...
Closing The Floodgates
The White Rock Creek basin in Dallas and Collin Counties, is one of Texas' most crucial resources. While large tracts of undeveloped land in Collin County remain under agricultural or...
