“…For example, Moody and Odem's (1999) high estimates of bankfull flow (26.8 m 3 s -1 ) and channel slope (1.6%) would place the river among high-energy streams that are prone to braiding, as characterized by Leopold and Wolman (1957) and Kondolf and others (2001), or to episodic floodplain stripping (Nanson and Croke 1992). The results from Phillips and Ingersoll (1998), by comparison, fall within the range of lower-energy meandering streams. If bankfull is not consistent, then it becomes difficult to interpret the river's dynamics using channel typing methodologies.…”

“…Phillips and Ingersoll (1998) reported historic stream gauge data indicating that the "low-flow" channel at the Paulden gauge had an area of 12.9 m 2 (139 ft 2 ), with a top width of 20.8 m (68 ft), a mean depth of 0.6 m (2 ft), and a discharge of 8.9 m 3 s -1 (313 ft 3 s -1 ). That discharge, which was only one-third of that estimated by Moody and Odem (1999), corresponds to a 1.3-year return interval.…”

This volume is a state-of-knowledge synthesis of monitoring and research conducted on the Upper Verde River (UVR) of Arizona. It contains information on the history, hydrology, soils, geomorphology, vegetation, and fish fauna of the area that can help land managers and other scientists in successfully conducting ecosystem management and future monitoring and research in this important Southwest river ecosystem. Chapter 1 provides an introduction to the UVR's location, vegetation, climate, soils, and watersheds. A historical and pictorial perspective of the UVR is presented in Chapter 2. The hydrology of the watershed and its current physical condition are covered in Chapters 3 and 4. Geomorphic relationships of the UVR channels are described in Chapter 5. The woody and herbaceous vegetation of the UVR are presented in Chapters 6 and 7. Water quality status and issues of the river are discussed in Chapter 8. The status of the fish fauna and other aquatic organisms are described in Chapter 9. Chapters 10 through 12 present summaries of information resources, research recommendations, a summary of this volume, and conclusions.

“…Additionally, the antidunes may collapse resulting in a surge of the water surface along the channel margins. The surge may cause super elevation of the high-water marks that would be surveyed following flow (Phillips and Ingersoll, 1998). The result would be an erroneously large area of flow and, therefore, erroneously large estimates of peak discharge.…”

“…When flows occur in these channels, sediment and other material eroded from or deposited on the streambed or banks can alter the cross-sectional area of the stream at a given stage and time. Additionally, the flow velocities may be impeded by the variable growth and alteration of vegetation along channel margins (Phillips and Ingersoll, 1998;Phillips and others, 1998). The forces of flow may even result in removal of vegetation and subsequent buildup of debris on downstream trees and structures.…”

Increasing drought favors nonnative fishes in a dryland river: evidence from a multispecies demographic model

et al. 2019

Understanding how novel biological assemblages are structured in relation to dynamic environmental regimes remains a central challenge in ecology. Demographic approaches to modeling species assemblages show promise because they seek to represent fundamental relationships between population dynamics and environmental conditions. In dryland rivers, rapidly changing climate conditions have shifted drought and flooding regimes with implications for fish communities. Our goals were to (1) develop a mechanistic multispecies demographic model that links native and nonnative species with river flow regimes, and (2) evaluate demographic responses in population and community structure to changing flow regimes. Each fish species was represented by a stage‐structured matrix, and species were coupled together into a multispecies framework through density‐dependent relationships in reproduction. Then, community dynamics were simulated through time using annual flow events classified from gaged streamflow data. We parameterized the model with vital rates and flow–response relationships for a community of native and nonnative fishes using literature‐derived values. We applied the simulation model to the Verde River (Arizona, USA), a major tributary within the Colorado River Basin, for the past half century (1964–2017). Model validation revealed a match between model projections and relative abundance trends observed in a long‐term fish monitoring dataset (1994–2008). At the beginning of the validation period (1994), model and survey observations showed that native species comprised approximately 80% of total abundance. Model projections beyond the survey data (2008–2017) predicted a shift from a native dominant to a nonnative dominant assemblage, coinciding with increasing drought frequency. Trade‐offs between native and nonnative species dominance emerged from differences in mortality in response to the changing sequence of major flow events including spring floods, summer high flows, and droughts. In conclusion, the demographic approach presented here provides a flexible modeling framework that is readily applied to other stream systems and species by adjusting or transferring, when appropriate, species vital rates and flow‐event thresholds.
