W. R. Osterkamp, National Research Program, U. S. Geological Survey (USGS), is a geomorphologist at the Desert Laboratory, Tucson, Arizona. He is interested in the factors that govern landscape stability, from hillslopes to bottomlands, and studies the nature and rate of recovery of these surfaces from natural and anthropogenic disturbance, and the role that vegetation plays in this recovery. This information can be used to plan engineering works and to manage riparian settings. Dr. Osterkamp also has investigated hydrologic processes, such as those involved in the origin and development of playa-lake basins in the Southern High Plains of Texas and New Mexico, the evolution of armored hillslopes, the geomorphic and hydrologic effects of transmission loss from arid-zone streamflow, and the processes of sediment storage, alluvial-landform development, and re-vegetation that follow catastrophic floods. Dr. Osterkamp holds undergraduate degrees in geology and chemistry from the University of Colorado and the MS and PhD degrees in geology and hydrology from the University of Arizona. He has been Project Chief, Sediment Impacts from Disturbed Lands, since 1980, is a former Research Advisor for the Geomorphology and Sediment Transport Discipline of the National Research Program, and is Adjunct Professor, University of Denver and University of Arizona.
In a broad sense, the principal objective being addressed by the project, Sediment Impacts from Disturbed Lands, is to develop an increased understanding of how landscape disturbance, whether natural or imposed, interacts with processes of climate, hydrology, geomorphology (including sediment transport), and biology to yield observed basin and landform characteristics. This broad-spectrum goal is intended to lead to an ability to manage processes within a drainage basin to minimize adverse effects of disturbance and to permit natural adjustment of the system toward a stable biophysical condition. Two obvious applications of the approach are to develop restoration or rehabilitation plans for degraded watersheds that will yield long-term adjustment among the processes that determine landscape characteristics, and to identify the influence on landscape properties and the ability of the system to re-adjust following natural disturbances, such as fire, catastrophic flood, and debris flow. Regardless of the cause of a disturbance, therefore, an objective is to understand how hydrologic and geomorphic processes can be induced to minimize the undesirable effects of the disturbance and thereby restore optimal use of the water resource.
Current emphases of the project are to investigate the bottomland changes that have occurred in the Snake River Basin of Idaho and Oregon following the late-Pleistocene Bonneville Flood, and to identify how land-use practices, flow depletion, and regulation have affected fluvial processes and habitat along the Platte River, central Nebraska, the Little Colorado River, eastern Colorado, and the Yellow River, northern China. The Snake River study is confounded by recent changes in characteristics of water and sediment discharge due to surface-water and ground-water extractions, severe regulation, and conversion of native vegetation to irrigated crops. A unique attribute of the investigation, however, is that it focuses on channel islands in the Snake River that reflect well the changes in climate, streamflow, and sediment yield during recent millennia. It is anticipated that this information will lead to an increased understanding of how changes imposed on large river systems affect the land and water resources of the drainage basin. The Platte River study, and a smaller-scale study along part of the Little Colorado River in eastern Arizona, are designed to identify the ways in which fluvial processes adjust in response to human-caused changes, principally flow regulation and depletion of surface- and ground-water supplies. Studies in the Yellow River Basin, China, are designed to address highly significant problems related to water shortages, sedimentation along the lower reach of the river, and the effects of catastrophic flooding.
The objectives of the project closely reflect a primary mission of the National Research Program and the Water Resources Discipline within USGS to understand those physical and biotic processes that influence the amounts and dynamics of water and sediment fluxes passing from uplands to channels to storage sites. Because a prime application of investigations within the project is to develop tools that will be effective in stream-corridor restoration and rehabilitation activities (an emerging national concern), it seems that continuing support of studies of the type addressed by this project are of fundamental importance to society.
Collaboration, mostly to provide technical input, with hydrologists within USGS but principally with practitioners at various levels of state and local governments, Chinese officials and colleagues, and consultants, recently has been requested frequently relative to procedures for effecting channel and bottomland rehabilitation. Both implicitly and explicitly, on-going studies along parts of the Snake, Platte, and Little Colorado Rivers are designed to yield information leading to stream-corridor rehabilitation. More narrowly focused studies for the same general purpose include investigations of how erosion-prediction technology can reduce adverse effects of sediment movement following forest fire, how equations describing the movement of bedload in stream channels can be applied more accurately than previously has been the case, and how landscape disturbance and resulting sediment movement due to bioturbation, especially the uprooting of trees, can be addressed to minimize adverse effects. Depending on how receptive Chinese officials may be to the alternatives that are being suggested for remediation of the Yellow River Basin, the impact could vary from insignificant to immense.
The general goal of the project for the next 5 years is to continue studies that will lead to enlightened management techniques for disturbed watersheds and landscapes. More specific goals are (1) to continue the on-going and comprehensive studies of the Snake River Basin, (2) to report results of the investigations by means of a monograph or other suitable publication venue, (3) to continue similar but less ambitious studies for the Platte and Little Colorado River Basins, (4) to develop guidelines for procedures to effect stream-corridor rehabilitation, with emphasis on degraded channels of the arid/semiarid West, and (5) to provide suggestions on how land- and water-use activities in the Yellow River Basin can be modified to alleviate some of the intense hydrologic and sedimentation problems that presently are confronting the people of northern and eastern China. The fourth goal is being pursued with the recognition that presently most rehabilitation/restoration activities are conducted without adequate knowledge of the processes that occur as a result of channel and bottomland alteration or the processes that must be reinstated to renew a stable, adjusted fluvial system. Another emphasis, therefore, will be on basin processes as opposed to site-specific data collection. The fifth goal is being conducted with the recognition that water and sediment problems of the Yellow River Basin are not restricted to biophysical processes but are related to economic and social issues as well; typical approaches of stream-corridor rehabilitation, therefore, may be poorly applicable or not applicable. Results of the Yellow River investigation are being reported in various manners including journals and conference proceedings. An additional product of the collaboration with Chinese colleagues is a planned International Watershed Research Network, which is to be managed by this project. It will be structured similarly to the Vigil Network, a system of small sites and drainage basins where geomorphic, hydrologic, and biological data are collected periodically, and like the Vigil Network ( http://wwwpaztcn.wr.usgs.gov/vigil/), will contain a database accessible by the internet.
For the National Research Program Project, Sediment Impacts from Disturbed Lands, W. R. Osterkamp has responsibility for all technical activities except data management. Tade Orr, Computer Specialist, maintains computer and similar technological capabilities, assumes a primary role in the storage of data for the project, and manages a World Wide Web site and the data in it that are related to the USGS-sponsored database of the Vigil Network. Barbara Gillespie, Administrative Technician, handles the majority of responsibilities for support personnel, funding details, contracts, and related services.
