GRAIP- Quantifying and Prioritizing Road Impacts

The Geomorphic Road Assessment and Inventory Package (GRAIP) is a process and a set of tools for analyzing the impacts of roads on forested watersheds. GRAIP combines a road inventory with a powerful GIS analysis tool set to predict sediment production and delivery, mass wasting risk from gullies and landslides, stream diversion potential, culvert maintenance and fish passage at stream crossings.

Hyporheic Exchange in Gravel Bed Rivers with Pool-Riffle Morphology

Hyporheic exchange (the mixing of streamflow and shallow groundwater) is poorly understood in gravel-bed rivers. These channels are particularly important habitat for salmonids, many of which are currently at risk worldwide and which incubate their offspring within the hyporheic zone.

ative brook trout have invaded and replaced native cutthroat trout in many Rocky Mountain streams. Methods to remove brook trout, such as chemical treatment and intensive electrofishing, are expensive, time-consuming, and sometimes controversial. An alternative technique used in control of unwanted insects, pheromone lures and traps, may be applicable to fish.
