Field Measurements Of Bed-Load Transport Distances Using Painted Sediment Tracers In An Urban Stream In The Missouri Ozarks, Kristen E. Breckenridge
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 …
Quantifying Pacific Lamprey (Entosphenous Tridentatus) Ammocoete Habitat Availability And The Risk Associated With The Summer Hydrograph Recession Limb In Coastal Northern California, Katrina Clare Nystrom
Quantifying Pacific Lamprey (Entosphenous Tridentatus) Ammocoete Habitat Availability And The Risk Associated With The Summer Hydrograph Recession Limb In Coastal Northern California, Katrina Clare Nystrom
Cal Poly Humboldt theses and projects
Pacific lamprey (Entosphenus tridentatus) are an anadromous fish that evolved before dinosaurs and are critical to the Pacific coastal stream ecosystems and Native American cultures. Pacific lamprey are threatened by past natural resource exploitation (logging, mining, dams, and streamflow diversion) and climate change (warming temperature and changing precipitation regime). The lamprey larva, known as ammocoetes, live in fine sediment deposits in coastal streams for three to seven years. The objective of this research was to predict ammocoete habitat based on channel morphology in coastal Northern California, USA and explore the impact of streamflow diversions on their habitat. I …
