Field Measurements Of Bed-Load Transport Distances Using Painted Sediment Tracers In An Urban Stream In The Missouri Ozarks, Kristen E. Breckenridge Aug 2020

Field Measurements Of Bed-Load Transport Distances Using Painted Sediment Tracers In An Urban Stream In The Missouri Ozarks, Kristen E. Breckenridge

MSU Graduate Theses

Predictions of bed-load mobility and transport in stream channels are useful for restoration and management purposes. This study uses native gravel tracers to determine transport distances for bed-load in an urban stream in the Ozark Highlands. The objectives of this project are to: (i) determine downstream transport distances of painted tracers of different sizes over a range of flow conditions; (ii) evaluate the influence of channel morphology and thalweg location on transport; and (iii) compare field results to those predicted by mobility equations. The study site is located on South Creek, which drains Springfield, Missouri. The study reach is 132 …

Wave Runup And Morphologic Change On A Mixed-Sediment Beach In The Salish Sea, Wa, Avery Maverick Jan 2020

Wave Runup And Morphologic Change On A Mixed-Sediment Beach In The Salish Sea, Wa, Avery Maverick

WWU Graduate School Collection

A primary threat to coastal regions is extreme water levels from tides, storm surges, and waves which drive coastal evolution. Predicting wave runup, the vertical extent of wave uprush on a beach above still water level, and the morphologic responses to storms within the Salish Sea is complex because of the high variability of shoreline exposure to waves and wind, morphology, coastal landforms, and tide range across the region. As part of a USGS study, this project was designed to assess how wave energy offshore drives runup, validate existing runup models (van der Meer, 2002; Stockdon et al., 2006; Didier …
