Reconnaissance investigation of sediment distribution, erosion, and transport in the upper Deschutes River, Deschutes County, Oregon, November 1986 Reconnaissance investigation of sediment distribution, erosion, and transport in the upper Deschutes River, Deschutes County, Oregon, November 1986
A preliminary investigation of sediment distribution, erosion, and transport in the upper Deschutes River was conducted in response to the perceived problem that brown trout spawning gravels were being rendered unusable due to an accumulation of fine-grained sediment. Contrary to the contention that channel gravels are being covered by fine-grained sediment, examination of the river...

A detailed chronology of the most recent eruption period at Mount Hood, Oregon A detailed chronology of the most recent eruption period at Mount Hood, Oregon
The most recent eruptive period of Mount Hood volcano, the Old Maid eruptive period, was characterized by volcano-hydrologic events (hydrologic events initiated by volcanic activity) which resulted in extensive lahar inundation in the White, Sandy, and Zigzag River drainages and produced a lithic pyroclastic flow which traveled at least 9 km down the White River from the vent area at...

Hydraulics and basin morphometry of the largest flash floods in the conterminous United States Hydraulics and basin morphometry of the largest flash floods in the conterminous United States
The maximum rainfall-runoff floods measured by indirect methods in small basins (0.39-370 km2) in the conterminous United States are examined. This analysis identified twelve floods that were the largest ever measured. These floods all occurred in semiarid to arid areas. For eleven of the twelve largest rainfall-runoff floods measured in small basins by the slope-area method, values of...

Rainfall, ground-water flow, and seasonal movement at Minor Creek landslide, northwestern California: Physical interpretation of empirical relations Rainfall, ground-water flow, and seasonal movement at Minor Creek landslide, northwestern California: Physical interpretation of empirical relations
Simple ground-water flow analyses can clarify complex empirical relations between rainfall and landslide motion. Here we present detailed data on rainfall, ground-water flow, and repetitive seasonal motion that occurred from 1982 to 1985 at Minor Creek landslide in northwestern California, and we interpret these data in the context of physically based theories. We find that landslide...

Coastal lava flows from Mauna Loa and Hualalai volcanoes, Kona, Hawaii Coastal lava flows from Mauna Loa and Hualalai volcanoes, Kona, Hawaii
A major carbonate reef which drowned 13 ka is now submerged 150 m below sea level on the west coast of the island of Hawaii. A 25-km span of this reef was investigated using the submersible Makali'i. The reef occurs on the flanks of two active volcanoes, Mauna Loa and Hualalai, and the lavas from both volcanoes both underlie and overlie the submerged reef. Most of the basaltic lava flows...
