Miller City levee break and incipient meander cutoff
On July 15, 1993, the flooding Mississippi River broke through a levee near Miller City, Ill., at the head of the Mississippi Embayment, approximately 55 km upstream from Cairo, Ill. Flow through the break crossed a high-amplitude meander bend and reentered the main channel approximately 24 km upstream from Cairo, bypassing 31 km of the river channel. The incipient meander cutoff is one of the mor

Historical land-use changes and potential effects on stream disturbance in the Ozark Plateaus, Missouri
Land-use changes have been blamed for creating disturbance in the morphology of streams in the Ozark Plateaus, Missouri (hereafter referred to as the Ozarks). Historical evidence and stratigraphic observations document that streams have been aggraded by substantial quantities of gravel beginning sometime at or near the time of European settlement of the Ozarks. Before European settlement, streams

The importance of fluvial hydraulics to fish-habitat restoration in low-gradient alluvial streams
1. A major cause of degradation and loss of stream fish is alteration of physical habitat within and adjacent to the channel. We describe a potentially efficient approach to fish restoration based upon the relationship between fluvial hydraulics, geomorphology, and those habitats important to fish.2. The aquatic habitat in a low-gradient, alluvial stream in the Ozark Plateaus physiographical provi

Introduction: Geomorphic studies of the storm and flood of November 3-5, 1985, in the upper Potomac and Cheat River basins
The heavy rains of November 3-5, 1985, produced record floods and extensive landsliding in the Potomac and Cheat River basins in West Virginia and Virginia (pl. 1). Although rainfall intensity was moderate, the storm covered a very large area and produced record floods for basins in the size range of 1000-10,000 km2. In addition, thousands of landslides were triggered on slopes underlain by shale

More than 3,000 landslides were triggered by heavy rainfall in the central Appalachian Mountains of West Virginia and Virginia, November 3-5, 1985. These landslides provided the opportunity to study spatial controls on landslides, magnitude and frequency of triggering events, and the effects of landslides on flood-induced geomorphic change. The study area consists of parts of the Wills Mountain an

Meteorology of the storm of November 3-5, 1985, in West Virginia and Virginia: Chapter B in Geomorphic studies of the storm and flood of November 3-5, 1985, in the upper Potomac and Cheat River basins in West Virginia and Virginia
The storm of November 3-5, 1985, in the central Appalachian Mountains of West Virginia and Virginia resulted from a complex sequence of meteorological events. The stage was set by Hurricane Juan, which made landfall in the Gulf Coast on October 31. Juan brought moisture northward up the Mississippi Valley; latent heat released by condensation aloft probably helped to render stationary a high-press

Earthquake-induced liquefaction features in the coastal setting of South Carolina and in the fluvial setting of the New Madrid seismic zone
Many types of liquefaction-related features (sand blows, fissures, lateral spreads, dikes, and sills) have been induced by earthquakes in coastal South Carolina and in the New Madrid seismic zone in the Central United States. In addition, abundant features of unknown and nonseismic origin are present. Geologic criteria for interpreting an earthquake origin in these areas are illustrated in practic
