Book excerpt: The original purpose of this investigation was to develop streambank erosion prediction curves for Northeast Kansas streams. Rosgen's (2001, 2006) methods were employed and eighteen study banks were measured and monitored over a four-year period, summer 2007 through summer 2010. At each study bank, a toe pin and two to three bank pins were set at a recorded longitudinal profile station of the stream. Vertical and horizontal measures from the toe pin to the bank face were taken each summer, 2007 as the baseline measure and 2008 - 2010 as bank change years. Bank profiles were overlaid to gain insight into bank area lost or gained due to erosional or depositional processes. A Bank Erosion Hazard Index (BEHI) and Near Bank Stress (NBS) combination rating was assessed and calculated for each study bank during the initial survey of 2007. The streambanks experienced varied erosion rates for similar BEHI/NBS combinations producing R2 values from 0.43 as the High/Very High BEHI rating and 0.80 as the Moderate BEHI rating. In addition, Moderate BEHI ratings provided higher erosion rates than the High/Very High BEHI rating and curves intersected at lower NBS ratings, suggesting a discrepancy in the fit of the model used in the Northeast Kansas region and conditions. In this light, modification of the BEHI model was evaluated and variables were assessed in the model for additional influence exerted in the Northeast Kansas region. Vegetation seemed to provide the most influence to bank resistance and was more closely evaluated. Banks with and without woody riparian vegetation were then plotted against BEHI and NBS values, as banks lacking woody vegetation eroded at higher rates. This study's findings can allow us to calibrate the BEHI model according to woody vegetation occurrence levels along streambanks in the Black Vermillion watershed. Modifications regarding vegetation occurrence of the BEHI model was completed and the results of these modifications generated R2 values of 0.78 for High/Very High BEHI and 0.82 for Moderate BEHI ratings. High/Very High ratings provided higher predicted erosion rates than Moderate ratings, while the curve slopes did not intersect at lower NBS ratings.

Bigham and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Excess sediment is a leading cause of stream impairment in the United States, resulting in poor water quality, sedimentation of downstream waterbodies, and damage to aquatic ecosystems. Numerous case studies have found that accelerated bank erosion can be the main contributor of sediment in impaired streams. An empirically-derived "Bank Assessment for Non-Point Source Consequences of Sediment" (BANCS) model can be developed for a specific hydrophysiographic region to rapidly estimate sediment yield from streambank erosion, based on both physical and observational measurements of a streambank. This study aims to address model criticisms by (1) evaluating the model repeatability and sensitivity and (2) examining the developmental process of a BANCS model by attempting to create an annual streambank erosion rate prediction curve for the Central Great Plains ecoregion. To conduct the repeatability and sensitivity analysis of the BANCS model, ten stream professionals with experience utilizing the model individually evaluated the same six streambanks twice in the summer of 2015. To determine the model repeatability, individual streambank evaluations, as well as groups of evaluations based on level of Rosgen course training, were compared utilizing Kendall coefficient of concordance and a linear model with a randomized complete block design. Additionally, a one-at-a-time design approach was implemented to test sensitivity of model inputs. Statistical analysis of individual streambank evaluations suggests that the implementation of the BANCS model may not be repeatable. This may be due to highly sensitive model inputs, such as streambank height and near-bank stress method selection, and/or highly uncertain model inputs, such as bank material. Furthermore, it was found that higher level of training may improve model implementation precision. In addition to the repeatability and sensitivity analysis, the BANCS model developmental process was examined through the creation of a provisional streambank erosion rate prediction curve for the Central Great Plains ecoregion. Streambank erosion data was collected sporadically from 2006 to 2016 from eighteen study banks within the sediment-impaired Little Arkansas River watershed of south-central Kansas. Model fit was observed to follow the same trends, but with greater dispersion, when compared to other created models throughout the United States and eastern India. This increase in variability could be due to (1) obtaining streambank erosion data sporadically over a 10-year period with variable streamflows, (2) BEHI/NBS ratings obtained only once in recent years, masking the spatiotemporal variability of streambank erosion, (3) lack of observations, and (4) use of both bank profiles and bank pin measurements to calculate average retreat rates. Based on the results of this study, a detailed model creation procedure was suggested that addresses several model limitations and criticisms. Recommendations provided in the methodology include (1) more accurate measurement of sensitive/uncertain BEHI/NBS parameters, (2) multiple assessments by trained professionals to obtain accurate and precise BEHI/NBS ratings, (3) the use of repeated bank profiles to calculate bank erosion rates, and (4) the development of flow-dependent curves based on annually assessed study banks. Subsequent studies should incorporate these findings to improve upon the suggested methodology and increase the predictive power of future BANCS models.

This book was released on 2016 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: The BANCS method has become a standard for predicting streambank erosion rates within a given region, but relies on subjective estimates of root density and has not been calibrated in the Gulf of Mexico coastal plain. This thesis presents three approaches to modeling streambank erosion rates. First, standard BANCS models were calibrated. Statistical analyses show that they are not significantly correlated to erosion rates due to inadequate estimates near-bank shear stress. Modifications to this estimate improve the models significantly (R2 = 0:31). Second, a statistical modeling process was developed using physical measurements, biomass density surveys, and soil analyses. The best statistical model requires similar data collection to BANCS, but offers higher accuracy (R2 = 0:54). Finally, a unique spatially-distributed model was developed. The model was designed to utilize global remote-sensing data and a physics-based hydrodynamic model and include the major sources of spatial and temporal variability. The model reproduces measured erosion rates with a Pearson's coefficient of R = 0:55. The spatially-distributed model allows streambank erosion rate to be estimated at any location on earth where channel geometry data are available and requires little to no field data collection. The model fills a long-standing gap in the prediction of regional sediment yield.

This book was released on 2014 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: According to the United States Environmental Protection Agency (USEPA), sediment is one of the most common water pollutants in the nation's rivers. Consequently, the identification of streambank locations with high erosion potential is important in reducing sediment input via management and monitoring practices. Furthermore, the estimation of erosion rates and sediment loads can assist in the development of Total Maximum Daily Loads (TMDLs). The objective of this study was to integrate two USEPA-recommended approaches with the Streambank Video Mapping System (SVMS) in order to predict site-specific Total Daily Sediment Loads (TDSLs) and calculate sediment TMDLs for streambank erosion over several river kilometers. The SVMS, a GPS-based watershed-scale data collection method, was incorporated with the USEPA-approved Bank Assessment for Non-point source Consequences of Sediment (BANCS) model to evaluate streambank erodibility using the Bank Erosion Hazard Index (BEHI) and stream erosivity using Near Bank Stress (NBS). The SVMS was implemented to collect georeferenced video footage of streambank condition using three above water cameras mounted on a kayak. In addition, GPS and stream width were concurrently recorded. The video was ocularly evaluated using four parameters of a modified BEHI (mBEHI): bank angle, bank height to bankfull ratio, surface protection, and riparian diversity. The site-specific mBEHI scores and NBS scores were used along with the North Carolina Piedmont region erosion prediction curves to estimate annual Bank Erosion Rates (BERs). Additionally, USGS stream gage discharge data was utilized to estimate TDSLs. Sediment TMDLs for streambank erosion were calculated using TDSL estimates and the Maximum Daily Limit (MDL) equation, a statistically-based long-term average approach devised by the USEPA. This integrated methodology was implemented on a 22.5 kilometer section of the Driftwood River in Indiana and a 20.4 kilometer section of Upatoi Creek in Georgia. The Total Sediment Load (TSL) of Driftwood River was 222 t yr−1. km−1 [tonnes per year per kilometer] and the TMDL was 66 t d−1 [tonnes per day]. The TSL for Upatoi Creek was 109 t yr−1 km-1 and the TMDL was 24 t d−1

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Sedimentation of Federal reservoirs in Kansas has been identified as a critical issue affecting municipal and industrial water supplies, flood control, recreation, and aquatic life. Eroding streambanks are major sources of sediment. Many streambank stabilization projects have been installed over the past 20 years, but there has been very little follow-up monitoring of the effectiveness of these practices. The project goal is to quantify the environmental benefits of government-sponsored streambank stabilization and restoration projects in northeastern Kansas, with a focus on six sites in which tree ad rock revetments were installed. Several of the sites had stabilized reaches and similar un-stabilized reaches as controls. Macroinvertebrate bioassessments were conducted at two sites, on the Delaware River and Plum Creek on the Kickapoo reservation, to compare eroding and stabilized stream reaches. Biotic Index, Biological Monitoring Working Party (BMWP), Average Score per Taxon (ASPT), and Elmidae - Plecoptera - Trichoptera (EIPT) were calculated to compare the stabilized sites performance for water quality and aquatic habitat. The biological indices showed habitat quality on stabilized reaches compared to control reaches. Alfa diversity Shannon-Wiener and Simpson indices were calculated and improve in habitat quality and macroinvertebrate diversity was shown in stabilized reaches. Two new cedar revetments were established in 2017 on Little Grasshopper and Wolfley creeks. These cedar revetment installations resulted in heavy sediment deposits after high flow events with the revetments retaining 121 and 48 cubic meters, respectively. A novel method of using exposed roots was used successfully to quantify erosion on Axtell-Schmidt Dairy farm creek and Wolfley creek, where we found an average yearly erosion of 3.39 and 10.26 cm respectively. Other sites also showed reduced erosion on stabilized reaches and a development of vegetation cover along the riparian areas near the streams. Cedar revetments are shown to be a cost-effective stabilization method on smaller streams. Also, these practices and evaluation methods are a good opportunity for community and stakeholder involvement because it is possible to train community members in the monitoring practices. It is recommended to continue monitoring these sites to compare them with the designated control in order to document long-term effects.

Book excerpt: The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

Available in PDF, EPUB and Kindle. Book excerpt: "Bridging the gap between qualitative and quantitative descriptions of natural rivers, Fluvial Hydraulics provides a sound understanding of water and sediment flows in natural rivers. This understanding is essential for modeling and predicting hydrologic and geomorphologic processes, erosion, sediment transport, water supply and quality, habitat management, flood hazards, and river restoration. The book will be especially valuable in providing a firm scientific basis for the growing field of river restoration. It bridges the gap between the highly quantitative mechanics-based civil-engineering approach to stream hydraulics and the more qualitative treatments of fluvial geomorphology typical of earth sciences and natural resources curricula. Many concepts are illustrated using measurements of natural river flows." "The book is specifically designed for upper-level students and practitioners who want to gain a better understanding of river behavior. The bases of the equations that are used to describe and predict river flows are systematically presented, including dimensional analysis."--BOOK JACKET.
