Available in PDF, EPUB and Kindle. Book excerpt: This research uses multivariate analysis to spatially assess channel network rejuvenation following a base-level drop. It develops and tests a GIS model to estimate the spatial distribution of channel incision with a focus on the loess-dominated tributary watersheds of the Missouri River in Nebraska and Iowa. In this homogenous-geologic setting, it was found that a multiplicative combination of base-level drop and a flow-length parameter (position ratio) performed better than any other tested combination of variables, explaining 73% of the variance in observed upstream streambed-elevation change and produced an overall predication sums of squares error of less than 0.4 meters. The position ratio method requires only a digital elevation model. This permits model extrapolation using map algebra to all stream sites responding to a base-level drop. This study focused on the degraded tributaries of the Missouri River from Gavins Point Dam (RM 811.4) to the confluence with Platte River (RM 594.60). The 280 km study reach of the Missouri River is shown to have degraded its bed by 0 to 4 meters since the closure of the Gavins Point Dam in 1954. The tributary streams to the Missouri River were selected because they provided several fundamental constraints on the problem including: (1) these loess-dominated stream channels were free from aggradational feedbacks common to coarser-grained alluvial channels, (2) complete rejuvenation of fluvial systems was documented to occur in less than 30 years, (3) an extensive historical record of streambed elevations has been assembled for these streams, (4) known sources of base-level drop were identifiable both in time and location, and (5) varied environmental conditions exist related to basin size, slope, flow lengths and landuse patterns. While the statistical linkage between base-level lowering and upstream-streambed lowering was an important finding, it was also expected. The two most significant contributions made by this study were (1) the creation of a new spatial model for the assessment of change in streambed elevation for networks responding to a base-level drop and (2) the production of a GIS layer (map) of expected tributary incision due to Middle Missouri River degradation.

Available in PDF, EPUB and Kindle. Book excerpt: The phenomenon of bed degradation can be due to a multiplicity of causes, but ultimately reflects a change in either the sediment input or sediment transport capacity of a system. Causes for the accelerated rate of degradation of the lower Missouri River Bed, particularly in Kansas City are explored as well as potential countermeasures to arrest the incision. Main-stem rivers and their tributaries constitute a complex, interrelated system and consequently the Platte and Kansas Rivers are briefly discussed as well. Although the lower Missouri River Valley has been inhabited for over two hundred years, significant changes on the scale required to disrupt sediment transport patterns has only occurred within the last century or so. Major channelization efforts orchestrated by the federal government began around the turn of the nineteenth century. These operations coupled with a series of main-stem dams built between the 1930s and 1960s served to provide a navigation channel for commercial barge traffic as well as provide flood protection. It appears that clear water releases from upstream reservoirs and effects of the Platte River contribute little to nothing as far as degradation processes at Kansas City are concerned. Channelization works probably play a minor role, as well as land-use changes, such as deforestation and urbanization. Significant causes to the recent increase in degradation rate are major flood events and commercial dredging. The river often degrades several feet during a single flood event and although some recovery occurs, the river's bed never reaches its previous elevation. Commercial dredging has significantly increased in the Missouri River in the same time frame that degradation has accelerated, occurring in the same areas as well. A few European rivers that also experience bed degradation were evaluated along with countermeasures applied to them. Unfortunately, the use of the European rivers lent itself to methods to arrest degradation that are unreasonable for use on the Missouri River. In light of the probable causes for degradation, the most effective countermeasure is likely a change in dredging regulations. Further study is required, though, to more satisfactorily determine the cause(s) of degradation as well as possible countermeasures.

Available in PDF, EPUB and Kindle. Book excerpt: Historically, the flow of sediment in the Missouri River has been as important as the flow of water for a variety of river functions. The sediment has helped form a dynamic network of islands, sandbars, and floodplains, and provided habitats for native species. Further downstream, sediment transported by the Missouri and Mississippi Rivers has helped build and sustain the coastal wetlands of the Mississippi River delta. The construction of dams and river bank control structures on the Missouri River and its tributaries, however, has markedly reduced the volume of sediment transported by the river. These projects have had several ecological impacts, most notably on some native fish and bird species that depended on habitats and landforms created by sediment flow. Missouri River Planning describes the historic role of sediment in the Missouri River, evaluates current habitat restoration strategies, and discusses possible sediment management alternatives. The book finds that a better understanding of the processes of sediment transport, erosion, and deposition in the Missouri River will be useful in furthering river management objectives, such as protection of endangered species and development of water quality standards.

Book excerpt: The changing focus and approach of geomorphic research suggests that the time is opportune for a summary of the state of discipline. The number of peer-reviewed papers published in geomorphic journals has grown steadily for more than two decades and, more importantly, the diversity of authors with respect to geographic location and disciplinary background (geography, geology, ecology, civil engineering, computer science, geographic information science, and others) has expanded dramatically. As more good minds are drawn to geomorphology, and the breadth of the peer-reviewed literature grows, an effective summary of contemporary geomorphic knowledge becomes increasingly difficult. The fourteen volumes of this Treatise on Geomorphology will provide an important reference for users from undergraduate students looking for term paper topics, to graduate students starting a literature review for their thesis work, and professionals seeking a concise summary of a particular topic. Information on the historical development of diverse topics within geomorphology provides context for ongoing research; discussion of research strategies, equipment, and field methods, laboratory experiments, and numerical simulations reflect the multiple approaches to understanding Earth’s surfaces; and summaries of outstanding research questions highlight future challenges and suggest productive new avenues for research. Our future ability to adapt to geomorphic changes in the critical zone very much hinges upon how well landform scientists comprehend the dynamics of Earth’s diverse surfaces. This Treatise on Geomorphology provides a useful synthesis of the state of the discipline, as well as highlighting productive research directions, that Educators and students/researchers will find useful. Geomorphology has advanced greatly in the last 10 years to become a very interdisciplinary field. Undergraduate students looking for term paper topics, to graduate students starting a literature review for their thesis work, and professionals seeking a concise summary of a particular topic will find the answers they need in this broad reference work which has been designed and written to accommodate their diverse backgrounds and levels of understanding Editor-in-Chief, Prof. J. F. Shroder of the University of Nebraska at Omaha, is past president of the QG&G section of the Geological Society of America and present Trustee of the GSA Foundation, while being well respected in the geomorphology research community and having won numerous awards in the field. A host of noted international geomorphologists have contributed state-of-the-art chapters to the work. Readers can be guaranteed that every chapter in this extensive work has been critically reviewed for consistency and accuracy by the World expert Volume Editors and by the Editor-in-Chief himself No other reference work exists in the area of Geomorphology that offers the breadth and depth of information contained in this 14-volume masterpiece. From the foundations and history of geomorphology through to geomorphological innovations and computer modelling, and the past and future states of landform science, no "stone" has been left unturned!
