“…Furthermore, if Manning's equation is assumed to hold, then x = 1/6 (Mueller, ). The surface velocity is equal to the value of Equation when d = d max , where d max is the total flow depth, and thus the coefficient p is given by Equation :

p = \frac{v_{italicsurf}}{{d_{max}}^{1 / 6}}

Supraglacial rivers on the Greenland ice sheet (GrIS) transport large volumes of surface meltwater toward the ocean, yet have received relatively little direct research. This study presents field observations of channel width, depth, velocity, and water surface slope for nine supraglacial channels on the southwestern GrIS However, we find that other, unobserved sources of flow resistance likely contributed to these elevated n values: future work should explicitly consider additional sources of flow resistance beyond bed roughness in supraglacial channels. We conclude that hydraulic modelling for these channels must allow for both sub-and supercritical flow, and most importantly must refrain from assuming that all ice-substrate channels exhibit similar hydraulic behavior, especially for Froude numbers and Manning's n.Finally, this study highlights that further theoretical and empirical work on supraglacial channel hydraulics is necessary before broad scale understanding of ice sheet hydrology can be achieved.

“…A widely accepted technique uses either a power law or log law to extrapolate velocity in the vertical direction. The one-sixth power law was used for this application for several reasons: (1) it is insensitive to noisy data (Simpson, 2001); 2it is the most widely accepted method that describes a wide range of flows (Chen, 1991); and (3) it has been adopted as a default processing protocol for USGS measurements unless the data warrant other power fits (Mueller, 2013).…”

of the data, and the writing of this report. Appreciation is extended to Curt Schmutte (California Department of Water Resources, retired) and managers at the Metropolitan Water District for recognizing the critical need and generating contractor's funding support for this effort. To the California Department of Water Resources program manager, Brett Harvey, and the California Department of Water Resources contracting manager, Jacob McQuirk, thank you for dealing with all of the contracting and purchasing issues associated with doing things on short notice and helping to guide the experiment and facilitating interagency coordination and communication. Ted Sommer, at the California Department of Water Resources, provided insightful comments on the initial draft proposal for this work and, along with Brett Harvey, helped guide the adaptive management of the study. These experiments involved many dedicated and talented people who worked in the field under challenging conditions-bad weather and high water, in this case. None of the results from this study would be possible without the heroic efforts of the fish-tagging and release teams, led by Marty Liedtke, and the instrument programming, deployment, and recovery teams, led by Chris Vallee; all are gratefully acknowledged.
