“…The thalweg was thus assumed to be in the center of the stream (Figure 1). Besides, the planar and profile designs of the riffles were similar to that in Shelley (2012) (Figure 1). The height of riffles (that is, the distance between the top and bottom of riffles, which is defined as bedform amplitude [A] in this study) was 40 mm in the laboratory model when the riffles were considered.…”

The exchange of water and substance across the surface-subsurface interface in a stream is termed as hyporheic exchange (HE) and the region that the HE flows through is called hyporheic zone (HZ) (Boano et al., 2014;Cardenas & Wilson, 2007a, 2007bVaux, 1968). The HE not only carries the dissolved and suspended matters into the HZ to support the benthic ecotone (Tonina & Buffington, 2011) but also transports nutrient-rich groundwater back to surface water, governing a variety of fundamental physical, chemical, and biological reactions in streams (Bencala, 2005). The HE thus plays a crucial part in stream ecosystem functions and water quality and has been increasingly studied during past decades (

“…The trapezoidal shape of the riffles followed the planar and profile designs of Stoesser et al. (2010), MacVicar and Rennie (2012), and Shelley (2012). The S was set at 0.6%, and a weir was installed at the outlet of the stream to control the water depth.…”

“…Similarly, trapezoid riffles with an amplitude of 0.04 m were prefabricated in a template using resin-bonded sand and then installed on the streambed. The trapezoidal shape of the riffles followed the planar and profile designs of Stoesser et al (2010), Rennie (2012), andShelley (2012). The S was set at 0.6%, and a weir was installed at the outlet of the stream to control the water depth.…”

Stream surface water, which carries suspended and dissolved matter, infiltrates the surrounding subsurface and exfiltrates back into the stream. This exchange process is called hyporheic exchange (HE) (Elliott & Brooks, 1997a, 1997bLiu & Chui, 2018;Vaux, 1968). The region of surrounding sediments involved in HE is called the hyporheic zone (HZ), which may exist at the streambed, stream bank, and floodplain. HE actively transports water-borne substances such as dissolved oxygen, nutrients, and fauna between the stream surface water and riparian zone, thereby creating a dynamic benthic ecotone in the HZ (Hancock, 2002) and supporting various fundamental physicochemical and biological processes (Tonina & Buffington, 2011). Thus, the HE plays a vital role in stream water quality and ecosystem function and the HZ has gained much attention in the general study of streams in the past several decades (

“…The usual objective is a bankfull capacity that would be typical of a natural stream with similar watershed characteristics in the same region. The natural bankfull discharge is estimated either from a hydraulic analysis of an unimpaired reach upstream or downstream of the restoration reach, or from a regional regression model that relates natural bankfull discharge to watershed characteristics [5].…”

The reference reach method is commonly used for natural stream design. In the reference reach approach, a stable reach is selected to serve as the design template for a design reach. The planform and profile of this reference reach must be scaled to fit the design site. Currently, the leading method for scaling uses a simple ratio of cross-sectional areas. This paper presents a simple method that employs hydraulic scaling to size the design reach to accommodate the desired bankfull flow. The method introduced in this paper is easy to use, does not require additional survey data, and should lead to more robust channel design.
