USE OF UnTRIM TO INVESTIGATE DISSOLVED OXYGEN TRANSPORT IN UPPER KLAMATH LAKE, OREGON

The hydrodynamic and constituent transport model UnTRIM was used to simulate hydrodynamics in Upper Klamath Lake, a shallow, hypereutrophic lake in which currents are responsive primarily to wind forcing. A simplified version of a dissolved oxygen model was used to simulate the transport of oxygen-depleted water from a deep trench on the western shoreline into important fish habitat in the nort...

Modeling variations of marine reservoir ages during the last 45 000 years

When dating marine samples with 14 C, the reservoir-age effect is usually assumed to be constant, although atmospheric 14 C production rate and ocean circulation changes cause temporal and spatial reservoir-age variations. These lead to dating errors, which can limit the interpretation of cause and effect in paleoclimate data. We used a 5 global ocean circulation model forced by transient atmos...

Wublet Tracer Testing in Klamath Falls, Oregon

A tracer test was carried out in a geothermal doublet system to study the injection behavior of a developed reservoir known to be fractured. The doublet produces about 320 gpm of 160' F heating and then injected; the wells are spaced 250 ft apart. observed in 2 hours and 45 minutes in the production well, indicating fracture flow. However, the tracer concentrations were low and indicated porous...
