We examine how historic flooding in 2011 affected the geomorphic adjustments created by dam regulation along the approximately 120 km free flowing reach of the Upper Missouri River bounded upstream by the Garrison Dam (1953) and downstream by Lake Oahe Reservoir (1959) near the City of Bismarck, ND, USA. The largest flood since dam regulation occurred in 2011. Flood releases from the Garrison D...

The history of geomorphology can be a valuable tool for educating students of geomorphology. The largest and most available record of what geomorphologists thought and did in the past is their original published work. Also available are some fine papers on the history of geomorphology that review and analyze primary sources and past events in the discipline in order to generalize, explain trend...

The flexural-slip fault (FSF), a type of secondary fault generated by bed-parallel slip, occurs commonly and plays an important role in accommodating fold growth. Although the kinematics and mechanics of FSFs are well studied, relatively few field observations or geometric models explore its geomorphic expression. In the Pamir-Tian Shan convergent zone, NW China, suites of well-preserved FSF sc...

Large rivers and their riparian zones are hot spots of biodiversity (WARD et al. 1999). Fluvial geomorphic processes provide the habitat diversity and the specific habitat conditions for characteristic species assemblages and result in high levels of habitat diversity, local species richness (α-diversity), and between-habitat differences (beta-diversity) and consequently, overall species richne...

Hydromorphological stream assessment has significantly expanded over the last years, but a need has emerged from recent reviews for more comprehensive, process-based methods that consider the character and dynamics of the river with greater accuracy. With this as a focus, a series of hydromorphological tools have been developed and/or further extended in Europe within the context of the REFORM ...

[1] The role of bedrock fractures and rock mass strength is often considered a primary influence on the efficiency of surface processes and the morphology of landscapes. Quantifying bedrock characteristics at hillslope scales, however, has proven difficult. Here, we present a new field‐based method for quantifying the depth and apparent density of bedrock fractures within the shallow subsurface...

kuhbanan fault system, as one of the intracontinental faults of central iran, is recognized by considerable seismogenic activities and modern morphotectonics evidences with a strike-slip (reverse component) motion. according to the geometric and kinematics data, kuhbanan fault has been divided into 5 segments (s26, s27, s28, s29, s30) in bahabad region. measured geomorphic indices of ratio of v...

in central part of kopeh dagh there is an array of active right-lateral strike-slip faults that obliquely cut the range and produce offsets of several kilometers in the geomorphology and geological structure. geomorphic indices indicate the presence of differential uplifting in history of this area. tectonic activity of the study area is investigated by a large number of dem derived catchments ...

Among the anthropogenic topographic signatures on Earth, open-pit mines are of great importance. Mining is of interest to geomorphologists and environmental researchers because of its implication in geomorphic hazards and processes. In addition, open-pit mines and quarries are considered the most dangerous industrial sector, with injuries and accidents occurring in numerous countries. Their fas...
