Groundwater Flow and Temperature Modeling to Predict Stream Temperatures in Beaver Creek, Kenai Peninsula, Alaska
Salmon are an important resource to the ecosystems, economy, and culture of the Kenai Peninsula, Alaska. However, salmon are under increasing stress due to warming water temperatures and decreasing stream flow. Groundwater is a major contributor to many streams that can help maintain fish habitat during low flows and contributes cooler water that regulates stream temperatures in the warm summer mo

Stream habitat assessment along a transect
Stream habitat data is collected along a series of transects marked by tape measure and includes estimating rock size categories (for example, sand, gravel, cobble, boulders) with a guide (shown).

Bank height above water surface assessment
Bank height above the water surface is measured at each transect along a stream reach to estimate the channel and bed substrate as well as the type and size of sediment size that can be transported by the stream.
