“…The mean value of the exponent of the bankfull mean depth regression For the southeastern portion of the U.S., Brockman et al (2012) reported that exponents of regional curves for bankfull mean depth typically ranged between 0.25 and 0.43. Based on prior studies, it was expected that mean bankfull depth would exhibit a greater number of poor fits than the other bankfull parameters (Table 7) (Chaplin, 2005;Keaton et al, 2005;Krstolic and Chaplin, 2007;Mistak and Stille, 2008;Brockman et al, 2012). In some instances, drainage area explained almost none of the variability in bankfull mean depth such as with HLRs 8, 14, 17, and 20, which had R 2 values of 0.10, 0.23, 0.22, and 0.22, respectively.…”

Regional curves relate drainage area to the bankfull channel characteristics discharge, cross‐sectional area, width, and mean depth. These curves are used for a variety of purposes, including aiding in the field identification of bankfull elevation and in the natural channel design process. When developing regional curves, the degree to which landform, geology, climate, and vegetation influence stream systems within a single physiographic province may not be fully considered. This study examined the use of the U.S. Geological Survey's Hydrologic Landscape Regions (HLR), as well as data from 2,856 independent sites throughout the contiguous United States (U.S.), to develop a set of regional curves (bankfull discharge, cross‐sectional area, width, and mean depth) for (1) the contiguous U.S., (2) each of the 20 HLRs, (3) each of the eight physiographic divisions, (4) 22 of the 25 physiographic provinces, and (5) individual HLRs within the physiographic provinces. These regional curves were then compared to each other, as well as those from the literature. Regional curves developed for individual HLRs, physiographic divisions, and physiographic provinces tended to outperform the contiguous U.S. indicating increased stratification was beneficial. Further stratifying physiographic provinces by HLR markedly improved regional curve reliability. Use of HLR as a basis of regional curve development, rather than physiographic region alone, may allow for the development of more robust regional curves.

“…Interestingly, none of the sites in this study had a return interval of 2.0 years or greater and only seven sites from the other studies exceeded 2.0 years or greater return intervals. Those with return intervals of 2.0 years or greater included four from Lotspeich (2009), one from Chaplin (2005), and one from Krstolic and Chaplin (2007), and one from Keaton et al (2005). Some design manuals, including the U.S. Army Corps of Engineers manual on channel stability (USACE, 1994), suggest that the bankfull discharge can be estimated by using the two-year return interval.…”

Regional curves are empirical relationships that can help identify the bankfull stage in ungaged watersheds and aid in designing the riffle dimension in stream restoration projects. Bankfull regional curves were developed from gage stations with drainage areas less than 102 mi2 (264.2 km2) for the Alleghany Plateau/Valley and Ridge (AP/VR), Piedmont, and Coastal Plain regions of Maryland. The AP/VR regions were combined into one region for this project. These curves relate bankfull discharge, cross‐sectional area, width, and mean depth to drainage area within the same hydro‐physiographic region (region with similar rainfall/runoff relationship). The bankfull discharge curve for the Coastal Plain region was further subdivided into the Western Coastal Plain (WCP) and Eastern Coastal Plain (ECP) region due to differences in topography and runoff. Results show that the Maryland Piedmont yields the highest bankfull discharge rate per unit drainage area, followed by the AP/VR, WCP, and ECP. Likewise, the Coastal Plain and AP/VR streams have less bankfull cross‐sectional area per unit drainage area than the Piedmont. The average bankfull discharge return interval across the three hydro‐physiographic regions was 1.4 years. The Maryland regional curves were compared to other curves in the eastern United States. The average bankfull discharge return interval for the other studies ranged from 1.1 to 1.8 years.

Bankfull Hydraulic Geometry Relationships for Rivers and Streams of the Western and Southwest Regions of Paran� State, Brazil

This study presents regional hydraulic geometry relationships for rivers and streams in the western and southwestern regions of the state of Paraná, Brazil. Regional hydraulic geometry relates the area of the river basin to the dimensions of the river channel (width, depth, channel capacity) and the flow measured at bankfull stage by potential functions. Both regions integrate a homogeneous area in the basaltic plateau of the Paraná sedimentary river basin. The climate is humid sub-tropical and the average rainfall is 1,830 mm annually. The nesting of the rivers in the study area does not allow the development of alluvial plains. For this reason, sandy deposits deposited by floods were used as a reference in defining bankfull stages. The data were collected by 46 fluviometric stations and reference sections, whose drainage areas ranged from 0.44 to 17,400 km 2 . The coefficients of determination (R 2 ) of the equations reached values between 0.911 and 0.966 and were valid for the studied regions and for alluvial stretches in rural areas.
