“…To estimate peak discharge for the La Valle study reach, we used a peak discharge‐to‐drainage area ratio based on the Baraboo river gage data. Streamflow of a given recurrence probability was estimated using the PeakFQ‐Flood Frequency Analysis based on the USGS's Bulletin 17B and the estimated peak discharge values (Flynn et al ., ). PeakFQ‐Flood Frequency Analysis applies a Pearson Type III frequency distribution to create estimates of instantaneous annual maximum peak flows for certain recurrence intervals (Flynn et al ., ).…”

We investigate stream response to the La Valle Dam removal and channel reconstruction by estimating channel hydraulic parameter values and changes in sedimentation within the reservoir. The designed channel reconstruction after the dam removal included placement of a riffle structure at the former dam site. Stream surveys undertaken in 1984 by Federal Emergency Management Agency and in 2001 by Doyle et al. were supplemented with surveys in 2009 and 2011 to study the effects of the instream structure. We created a model in HEC‐RAS IV and surface maps in Surfer© using the 1984, 2009, and 2011 surveys. The HEC‐RAS IV model for 2009 channel conditions indicates that the riffle structure decreases upstream channel shear stress and velocity, causing renewed deposition of sediment within the former reservoir. We estimate by 2009, 61% of former reservoir sediments were removed during dam removal and channel reconstruction. Between 2009 and 2011 renewed sedimentation within the former reservoir represented approximately 7.85% of the original reservoir volume. The HEC‐RAS IV models show the largest impacts of the dam and riffle structure occur at flood magnitudes at or below bankfull. Thus, the riffle and the dam similarly alter channel hydraulics and sediment transport. As such, our models indicate that the La Valle Dam project was a dam replacement rather than a removal. Our results confirm that channel reconstruction method can alter channel hydraulics, geomorphology, and sediment mobility.

“…The frequency of peak discharges recorded at the USGS gage at Renton (12119000) between water years 1946 and 2015 was analysed with the Peak flow Frequency (PEAKFQ 7.0) analysis program (Flynn, Kirby, & Hummel, ; Veilleux, Cohn, Flynn, Mason, & Hummel, ), using the Bulletin 17B method of the Interagency Advisory Committee on Water Data methodology (IACWD, ). The USGS gage at Renton is located upstream of the Cedar River's outlet to Lake Washington and between 6 and 31 km downstream from the study reaches with minor tributaries entering the Cedar River in the intervening distance (Figure ).…”

Streambed scour of salmon spawning habitat in a regulated river influenced by management of peak discharge

In the Pacific Northwest of the United States, salmon eggs incubating within streambed gravels are susceptible to scour during floods. The threat to egg‐to‐fry survival by streambed scour is mitigated, in part, by the adaptation of salmon to bury their eggs below the typical depth of scour. In regulated rivers globally, we suggest that water managers consider the effect of dam operations on scour and its impacts on species dependent on benthic habitats. We instrumented salmon‐spawning habitat with accelerometer scour monitors (ASMs) at 73 locations in 11 reaches of the Cedar River in western Washington State of the United States from Autumn 2013 through the Spring of 2014. The timing of scour was related to the discharge measured at a nearby gage and compared to previously published ASM data at 26 locations in two reaches of the Cedar River collected between Autumn 2010 and Spring 2011. Thirteen percent of the recovered ASMs recorded scour during a peak‐discharge event in March 2014 (2‐to 3‐year recurrence interval) compared to 71% of the recovered ASMs during a higher peak‐discharge event in January 2011 (10‐year recurrence interval). Of the 23 locations where ASMs recorded scour during the 2011 and 2014 deployments, 35% had scour when the discharge was ≤87.3 m3/s (3,082 ft3/s) (2‐year recurrence interval discharge) with 13% recording scour at or below the 62.3 m3/s (2,200 ft3/s) operational threshold for peak‐discharge management during the incubation of salmon eggs. Scour to the depth of salmon egg pockets was limited during peak discharges with frequent (1.25‐year or less) recurrence intervals, which managers can regulate through dam operations on the Cedar River. Pairing novel measurements of the timing of streambed scour with discharge data allows the development of peak‐discharge management strategies that protect salmon eggs incubating within streambed gravels during floods.

“…Discharge was calculated using Manning's equation in HydraFlow Express software for stages corresponding to the height at which water begins to inundate the top surface of alluvial features identified in the field to determine capacity of the channel. Discharges were compared to flood frequency values from a gage (USGS 07050700 James River near Springfield, Missouri) at Kinser Bridge that has a 53-year record using the USGS's Peakfreq Bulletin 17b software (Flynn et al, 2006).…”

Historical Disturbance and Contemporary Floodplain Development along an Ozark River, Southwest Missouri

2011

View full text Add to dashboard Cite

The James River Basin (3,770 km 2 ) in the Ozark Plateaus of Missouri was largely settled by the 1850s. However, little is known about how it responded to and recovered from early land disturbance. This study characterizes the distribution and thickness of historical overbank sedimentation along the upper James River through topographic surveys, subsurface floodplain sediment sampling, and historical aerial photo analysis. Stratigraphic markers used for this study include buried soils, metal tracers from mining operations, and cesium-137. Between 0.5 and 1 m of overbank deposition occurred on floodplains since settlement, with the highest rates coinciding with peak corn production in the late 1800s. A contemporary shelf has been developing in disturbance reaches since the 1880s. However, aerial photo records show that much of the channel has been stable since the 1950s. Current channel capacity at the floodplain stage is near the Q 1.5 year flood, suggesting that it is adjusted to the current flood regime. However, the shelf forming below the floodplain stage in disturbance reaches may indicate that channels are still recovering from past disturbance. Apparently, Ozark rivers responded quickly to land disturbance, but recovery has lagged, perhaps due to decreased sediment loads following agricultural conversion to pasture and implementation of soil conservation practices.
