Fluvial disturbance patches and cottonwood recruitment along the upper Missouri River, Montana
G.T. Auble, M. L. Scott
1998, Wetlands (18) 546-556
The disturbance patches most suitable for seedling establishment of pioneer riparian trees are also subject to future disturbances that produce high seedling mortality. We are monitoring plains cottonwood seedling establishment and mortality along the Wild and Scenic reach of the Missouri River upstream of Fort Peck Reservoir, Montana at four...
Downstream effects of dams on channel geometry and bottomland vegetation: Regional patterns in the Great Plains
Jonathan M. Friedman, W. R. Osterkamp, M. L. Scott, G.T. Auble
1998, Wetlands (18) 619-633
The response of rivers and riparian forests to upstream dams shows a regional pattern related to physiographic and climatic factors that influence channel geometry. We carried out a spatial analysis of the response of channel geometry to 35 dams in the Great Plains and Central Lowlands, USA....
Processes of fluvial island formation, with examples from Plum Creek, Colorado and Snake River, Idaho
W. R. Osterkamp
1998, Wetlands (18) 530-545
A fluvial island is a landform, elevated above and surrounded by stream-channel branches or waterways, that persists sufficiently long to establish permanent vegetation. Natural fluvial islands occur in any part of a drainage network but most commonly in montane, piedmont-valley, and coastal flood-plain environments. Processes, often interactive,...

Somerset County Flood Information System
William M. Summer
1998, Fact Sheet 090-98
IntroductionThe timely warning of a flood is crucial to the protection of lives and property. One has only to recall the flood of August 2, 1973, in Somerset County, New Jersey, in which six lives were lost and major property damage occurred, to realize how unexpected and costly, especially in...
New Jersey Tide Telemetry System
William M. Summer
1998, Fact Sheet 091-98
Each summer the population of the barrier-island communities of New Jersey increases by tens of thousands. When a hurricane threatens these communities, the few bridges and causeways that connect the islands with the mainland become overcrowded, making evacuations from the barrier islands to the mainland difficult. Timely evacuation depends on...
Multibeam data and socio-economic issues in west-central San Francisco Bay

1998, Open-File Report 98-139
San Francisco Bay is the largest estuary on the conterminous U.S. Pacific Coast and is one of the world's largest natural harbors. It is a biologically productive and diverse environment. San Francisco Bay has a maritime economy that annually generates over $7.5 billion, handles 50 million tons of cargo, and...
Ground water resources of the Mille Lacs Lake area, east-central Minnesota
L. C. Trotta, T.K. Cowdery
1998, Water-Resources Investigations Report 97-4116
The Mille Lacs Lake study area is a 960 mi2 area containing the ground-water and surface-water drainages to both Mille Lacs Lake and the first 12 miles of the Rum River. Within this study area, available ground water occurs in saturated, overlapping, discontinuous, partially-connected, glacially-deposited (hereinafter, glacial) aquifers and in...

FEMFLOW3D; a finite-element program for the simulation of three-dimensional aquifers; version 1.0
Timothy J. Durbin, Linda D. Bond
1998, Open-File Report 97-810
This document describes a computer program that simulates three-dimensional ground- water systems using the finite-element method. The program was developed to simulate regional ground-water systems, but it can be applied to small-scale problems as well. This program can be used to simulate both confined and water-table aquifers. The program simulates a...
