  • Timescale Dependence in River Channel Migration Measurements
    TIMESCALE DEPENDENCE IN RIVER CHANNEL MIGRATION MEASUREMENTS Abstract: Accurately measuring river meander migration over time is critical for sediment budgets and understanding how rivers respond to changes in hydrology or sediment supply. However, estimates of meander migration rates or streambank contributions to sediment budgets using repeat aerial imagery, maps, or topographic data will be underestimated without proper accounting for channel reversal. Furthermore, comparing channel planform adjustment measured over dissimilar timescales are biased because shortand long-term measurements are disproportionately affected by temporary rate variability, long-term hiatuses, and channel reversals. We evaluate the role of timescale dependence for the Root River, a single threaded meandering sand- and gravel-bedded river in southeastern Minnesota, USA, with 76 years of aerial photographs spanning an era of landscape changes that have drastically altered flows. Empirical data and results from a statistical river migration model both confirm a temporal measurement-scale dependence, illustrated by systematic underestimations (2–15% at 50 years) and convergence of migration rates measured over sufficiently long timescales (> 40 years). Frequency of channel reversals exerts primary control on measurement bias for longer time intervals by erasing the record of observable migration. We conclude that using long-term measurements of channel migration for sediment remobilization projections, streambank contributions to sediment budgets, sediment flux estimates, and perceptions of fluvial change will necessarily underestimate such calculations. Introduction Fundamental concepts and motivations Measuring river meander migration rates from historical aerial images is useful for developing a predictive understanding of channel and floodplain evolution (Lauer & Parker, 2008; Crosato, 2009; Braudrick et al., 2009; Parker et al., 2011), bedrock incision and strath terrace formation (C.

The upper watershed south of river mile (RM) 10 lies entirely within private and state timberlands, federal national forests, and the Olympic National Park. Development is concentrated along the lower 10 miles, where the river flows through relatively steep (i.e. gradients up to 1%), glacial and glaciomarine deposits (Drost 1983, BOR 2002).

Channel migration is driven by river flows, but short-term records cannot Meandering river disentangle the effects of land use, flow diversion, past floods, and climate change. We used three data sets to Aerial photography quantify nearly two centuries of channel migration on the Powder River in Montana. The most precise data set Dendrochronology came from channel cross sections measured an average of 21 times from 1975 to 2014. We then extended spatial Channel cross section and temporal scales of analysis using aerial photographs (1939–2013) and by aging plains cottonwoods along transects (1830–2014). Migration rates calculated from overlapping periods across data sets mostly revealed cross-method consistency. Data set integration revealed that migration rates have declined since peaking at 5 m/ year in the two decades after the extreme 1923 flood (3000 m3/s).

  • An Abstract of the Dissertation Of
    AN ABSTRACT OF THE DISSERTATION OF Peter J. Wampler for the degree of Doctor of Philosophy in Geology presented on July 14, 2004. Title: Contrasting Geomorphic Responses to Climatic, Anthropogenic, and Fluvial Change Across Modern to Millennial Time Scales, Clackamas River, Oregon. Abstract approved: Gordon E. Grant Geomorphic change along the lower Clackamas River is occurring at a millennial scale due to climate change; a decadal scale as a result River Mill Dam operation; and at an annual scale since 1996 due to a meander cutoff. Channel response to these three mechanisms is incision. Holocene strath terraces, inset into Pleistocene terraces, are broadly synchronous with other terraces in the Pacific Northwest, suggesting a regional aggradational event at the Pleistocene/Holocene boundary. A maximum incision rate of 4.3 mm/year occurs where the river emerges from the Western Cascade Mountains and decreases to 1.4 mm/year near the river mouth. Tectonic uplift, bedrock erodibility, rapid base-level change downstream, or a systematic decrease in Holocene sediment flux may be contributing to the extremely rapid incision rates observed. The River Island mining site experienced a meander cutoff during flooding in 1996, resulting in channel length reduction of 1,100 meters as the river began flowing through a series of gravel pits. Within two days of the peak flow, 3.5 hectares of land and 105,500 m3 of gravel were eroded from the river bank just above the cutoff location. Reach slope increased from 0.0022 to approximately 0.0035 in the cutoff reach. The knick point from the meander cutoff migrated 2,290 meters upstream between 1996 and 2003, resulting in increased bed load transport, incision of 1 to 2 meters, and rapid water table lowering.
