An investigation into modeling snow cover elements at Crater Lake National Park and surrounding environs as an improved "ground truth" method for satellite snow observations

O Criador:

Hamilton, William L.

Abstract:

Streamflow forecasts are essential to the optimal operation of hydroelectric and irrigation reservoirs in the Pacific Northwest. Satellite snow cover observations would aid in these streamflow forecasts by providing snow cover data at regular time intervals. Unfortunately, satellite capability to remotely sense mountain snow cover conditions is indeterminate due to...

Vegetation ecology and net primary productivity of selected freshwater wetlands in Oregon

O Criador:

Boss, Theodore R. (Theodore Robert)

Abstract:

Vegetation ecology of eight Oregon freshwater wetlands was described and net aerial primary productivity estimated in four wetlands. Plant cover samples were used to classify 37 wetland and 11 terrestrial communities by agglomerative hierarchical clustering. Samples and species were ordinated. Direct measurements were made of sample relative elevation, inundation duration,...
