Environmental Effects
What are the conditions at tidal
energy sites?
What is the optimal design for tidal devices and
arrays?
How can the benefits from
testing be maximized?
How can impacts be mitigated?

Resource and Site Assessment - Motivation Site-specific information is
needed by multiple parties:Optimal siting
Existing information is insufficient Approaches to close knowledge
gaps are underdeveloped

Rivers and Constructed Channels Potential for power generation
from in-stream turbines installed in the fast-moving waters downstream from Columbia River dams
Incremental environmental impact should be very small
In-stream turbines for flow control and power generation as potential alternative for energy-dissipating sluice gates
