Available in PDF, EPUB and Kindle. Book excerpt: Fisheries and natural resource managers and policymakers need more efficient procedures for identifying sources of variability in ecosystems (natural and managed) and assessing uncertainties of managing and making decisions for developing and implementing river restoration strategies. This book seeks to integrate perspectives on variability of physical and biological functions and concepts of uncertainty in natural and managed systems, into strategies for renewing and conserving river ecosystems. The book explores approaches to understanding and communicating the processes contributing to the variability of different types of river systems, and to assessing major sources of uncertainty in natural and managed river ecosystems.
Book Synopsis Estimating Large Woody Debris Recruitment from Adjacent Riparian Areas by : Kathleen P. Minor
Download or read book Estimating Large Woody Debris Recruitment from Adjacent Riparian Areas written by Kathleen P. Minor and published by . This book was released on 1997 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large woody debris recruitment to streams from adjacent riparian forests influences stream channel morphology, sediment routing, and fish habitat. A mathematical model was developed to 1) determine whether the trees in a stand adjacent to a stream, upon falling, would provide large woody debris of a specified size to the stream and 2) determine the volume of trees, upon falling, that reach a stream over a specific time period. The model considered stand and topographic parameters such as tree size, tree form, distance from the stream, hill slope gradient, stream gradient, stream width, riparian buffer width, and basal area of the stand. The likelihood that a tree of a specified size will reach the channel is the probability the tree will fall in a given direction evaluated at 1 degree azimuths from 0 to 360 degrees multiplied by the probability it is tall enough to reach the stream. Volume estimates were calculated by multiplying estimated tree volumes by the joint probabilities. A test riparian polygon comprised of Douglas-fir (Pseudotsuga menziesii {Mirb.] Franco) was selected to illustrate how the model predicts large woody debris recruitment of both key pieces and volume to an adjacent stream. Estimating large woody debris recruitment to streams from adjacent riparian stands over several decades may be useful in determining effectiveness of various configurations of riparian buffers and provide assistance in the prediction of the future quality of aquatic and terrestrial habitats in riparian zones. This model provides one way to estimate where large wood is coming from within a riparian leave area and could be useful in determining necessary widths for riparian areas that are intended to provide large woody debris recruitment over time.
Book Synopsis Short Term Effectiveness of High Density Large Woody Debris in Asotin Creek as a Cheap and Cheerful Restoration Action by : Reid Camp
Download or read book Short Term Effectiveness of High Density Large Woody Debris in Asotin Creek as a Cheap and Cheerful Restoration Action written by Reid Camp and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In response to human impacts, river restoration and rehabilitation actions have become a priority in the United States. In the Pacific Northwest, most restoration actions are focused on repairing degraded freshwater habitat to increase or improve Pacific salmonid production. However, traditional river restoration actions remained largely unchanged for over 100 years despite a lack of definitive evidence that the actions were effective. More recently, there has been a surge in process-based restoration actions, which aim to reestablish the physical and biological processes that maintain fluvial and floodplain environments by targeting the root causes of degradation in a watershed. Cheap and cheerful restoration projects focus on restoration actions that are low impact and cost effective, can be implemented over large scales, and target degraded processes. However, because cheap and cheerful restoration is a relatively new method, the success of these types of projects has not been assessed. To address this issue, I studied the short-term physical effectiveness of a type of cheap and cheerful restoration that uses high density large woody debris (HDLWD) to restore instream habitat complexity in two wadeable tributaries to Asotin Creek in southeast Washington State. My specific research objectives included (1) assessing hydraulic and geomorphic responses in the stream channel imposed by restoration structures, (2) quantifying the changes to geomorphic channel unit assemblages post restoration, (3) quantifying changes in sediment storage post restoration, and (4) developing a geomorphic condition assessment of Asotin Creek using the River Styles Framework. Additionally, I developed a mobile database application (app) to facilitate data collection using a novel rapid restoration effectiveness assessment survey. Through analysis and a thorough review of the land use history in Asotin Creek, I determined that much of the watershed is in poor geomorphic condition based on the River Styles Framework for river classification. Many stream reaches have been degraded from their historic condition and often lack habitat complexity associated with suitable rearing habitat for juvenile salmonids. My results indicate that the structures are impose several immediate hydraulic responses following installation. These hydraulic responses increase hydraulic roughness, which results in predictable geomorphic responses following high flow events. Following restoration, the number and area of pools and bars significantly increased within treatment sites, while the number and area of planar units decreased. Likewise, it appears that the addition of the structures has led to a 25% increase in depositional volume at treatment sites compared to control sites. Results from the rapid assessment approach supported the more vetted approaches used to assess the efficacy of the treatment. However, the viability of the app and rapid protocol indicate that inter-observer variability may be high, and estimates of geomorphic unit area are not entirely consistent with the vetted approaches. Analysis of the rapid assessment approach revealed pertinent improvements to the app and rapid protocol that will be made in the future.

Book Synopsis Fine Organic Debris and Dissolved Oxygen in Streamed Gravels in the Oregon Coast Range by : Arne E. Skaugset
Download or read book Fine Organic Debris and Dissolved Oxygen in Streamed Gravels in the Oregon Coast Range written by Arne E. Skaugset and published by . This book was released on 1980 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intragravel organic loading and intragravel dissolved oxygen were studied to determine the relationship between timber harvesting adjacent to first-, second-, and third-order streams and intragravel water quality. Twenty watersheds in the central Coast Range of western Oregon were studied of which five were undisturbed, nine were partially harvested, and six were completely harvested. Intragravel dissolved oxygen was sampled by accessing intragravel water with a small, steel probe and dissolved oxygen was determined with a membrane electrode and dissolved oxygen meter. Streambed gravels were sampled with a liquid nitrogen freeze-core technique and the organics were separated from the inorganics by elutriation. Intragravel organic loading averaged 6.6 gms/l. core volume and ranged from 0.2 to 79.5. Intragravel dissolved oxygen averaged 6.5 mg/l. and ranged from 2.2 to 10.8 while iritragravel dissolved oxygen depression averaged 34% and ranged from 0% to 74%. Partially harvested watersheds had significantly ([alpha]= .01) lower intragravel organic loading than the undisturbed or completely harvested Gravels in the Oregon Coast Range. watersheds which were not significantly different. A reduction of large organic debris was observed in the partially harvested watersheds. This could have modified the stream's retention capacity for fine organic debris and in turn reduced intragravel organic loading. The most significant variables associated with intragravel organic loading in the multiple linear regression equations were: sample depth, streambed porosity, percent inorganic fines, and large organic debris loading. An increase in any of these variables indicated increased intragravel organic loading. When percent area harvested and length of streambank with harvesting adjacent were included in a regression equation, they explained a small, but significant amount of the variation in intragravel organic loading. Increased harvesting activities as indicated by these variables were associated with decreased intragravel organic loading. There was no significant difference in intragravel dissolved oxygen depression between the undisturbed, partially harvested, and completely harvested watersheds. Percent inorganic fines was the single most significant variable correlated with intragravel dissolved oxygen depression in the multiple linear regression equations. An increase in inorganic fines was associated with decreased intragravel dissolved oxygen. Another group of variables which were indicators of watershed size was correlated with intragravel dissolved oxygen depression. The relationship indicated that larger watersheds were associated with higher intragravel dissolved oxygen. The general conclusion drawn from this study is that timber harvesting in the Oregon Coast Range has not had an adverse impact upon intragravel dissolved oxygen by increasing intragravel organic loading.
