“…The concentration of suspended sand and mud was greatest on the first day of the HFE and quickly decreased thereafter (Rubin and others, 1998;Topping andothers, 1999, 2000;Rubin and Topping, 2001). These findings, coupled with modeling that showed that the highest rates of sandbar deposition occurred during the first days of the high flow (Wiele and Torizzo, 2005), led to the decision to reduce the duration of the 2004 and 2008 HFEs to less than one-half the duration of the 1996 HFE. The last days of the 1996 HFE transported much less fine sediment and did not substantially increase deposition of eddy sandbars .…”

“…In contrast, eddy deposition (a sand sink for the routing model) occurs more continuously over time in response to the sand delivered from the main flow to the eddy. The time dependence of eddy deposition and the rapid scour of lower eddy deposits associated with increased discharge have been demonstrated by previous model applications [e.g., Wiele and Torizzo , 2005] and surveys repeated during depositional events [ Andrews et al , 1999]. Thus eddy scour is calculated as a function of change in discharge, whereas eddy deposition is calculated by using a deposition rate over time.…”

[1] Spatial complexity in channel geometry indicates that accurate prediction of sediment transport requires modeling in at least two dimensions. However, a one-dimensional model may be the only practical or possible alternative, especially for longer river reaches of practical concern in river management or landscape modeling. We have developed a one-dimensional model of the Colorado River through upper Grand Canyon that addresses this problem by reach averaging the channel properties and predicting changes in sand storage using separate source and sink functions coupled to the sand routing model. The model incorporates results from the application of a two-dimensional model of flow, sand transport, and bed evolution, and a new algorithm for setting the near-bed sand boundary condition for sand transported over an exposed bouldery bed. Model predictions were compared to measurements of sand discharge during intermittent tributary inputs and varying discharges controlled by dam releases. The model predictions generally agree well with the timing and magnitude of measured sand discharges but tend to overpredict sand discharge during the early stages of a high release designed to redistribute sand to higher-elevation deposits.Citation: Wiele, S.

“…Models of flow and sediment transport have been used to examine environmentally damaged and vulnerable rivers (for example, Wiele and others, 2007) and improve management of environmental recovery (for example, Wiele and Torizzo, 2005). Calculations of the hydraulic properties of in-stream microhabitat have been used to examine seasonal variations and effects of dam operation on in-stream microhabitat (Korman and others, 2004).…”

ISSN 2328-0328 (online) iii AcknowledgmentsThis project was developed and funded in cooperation with The Nature Conservancy (TNC). Dan Campbell (retired), Jeanmarie Haney, and Kimberly Schoneck at TNC provided crucial support and expertise regarding the Verde River watershed. Additional funding from the Salt River Project and the U.S. Geological Survey (USGS) WaterSMART program made possible the extension of the project to the development of study sites, sampling, and sample analysis.Twice during the project, we invited a work group to meet and provide comments and suggestions concerning the direction and focus of our work to keep it relevant to the goals of developing information useful for resource policy and management. Jeanmarie Haney (TNC), Shaula Hedwall (U.S. Fish and Wildlife Service), Charles Paradzick (Salt River Project), John Rasmussen (Yavapai County Water Advisory Committee Coordinator), Patti Spindler (Arizona Department of Environmental Quality, ADEQ), Abe Springer (Northern Arizona University), and David Ward (USGS Grand Canyon Monitoring and Research Center) contributed many insights that strengthened the project.Data and analyses directly incorporated into the report or used as background information were generously shared by agencies and individuals. Charlie Cave (Yavapai County Flood Control District) provided aerial photographs and detailed topographic maps commissioned by Yavapai County; the hydrological consulting firm HDR, with the permission of Yavapai County, provided a detailed report documenting their hydraulic modeling for the county. Patti Spindler (ADEQ) and Andy Clark (Arizona Game and Fish Department) generously shared valuable macroinvertebrate and fish datasets that were crucial to the report's primary analyses. Jocelyn Gretz provided valuable support for field work and planning. Steve Wiele provided much valuable assistance and support in the development of the project generally and to the section on surface water and groundwater in particular.
