Complexity of a debris-flow system at Forest Falls, California

Kerry Cato & Brett Goforth
Historical patterns of debris flows have been reconstructed at the town of Forest Falls in the San Bernardino Mountains using a variety of field methods (mapping flow events after occurrence, dendrochronology evidence, soil chrono sequences). Large flow events occur when summer thunderstorms produce brief high-intensity rainfall to mobilize debris, however the geomorphic system exhibits properties of non-linear response rather than being a single-event precipitation-driven process. Previous studies contrasted the relative water content of flows generated...

Monitoring and early warning of debris-flow in an earthquake impacted area, Baishahe catchment, southwest China

Hongling Tian, Zongji Yang, Jianping Qiao & Lili Shi
After 10 years of the Wenchuan earthquake of China, the post-seismic landslides are turning weak. However, the debris flows in earthquake-stricken area continue to be threat. In order to reduce the risk from debris flows in this region, we discuss the operation of an alert system, monitoring objectives, and early-warning policies. Three gullies in the Baishahe catchment, Dujiangyan, Southwest China were selected and rain-gauge, tilt-sensor, mud-meter and ground acoustic meter combined to a warning system...

Rainfall intensity limitation and sediment supply independence of post-wildfire debris flows in the western U.S.

Paul M. Santi & Blaire MacAulay
This work explores two hypotheses related to post-wildfire debris flows: first, that they are rainstorm-intensity limited and not rainstorm-volume limited, and second, that they are not sediment-supply limited. The first hypothesis suggests that it is common to generate more than enough water to account for the volume in the debris flow, but to actually produce a debris flow the water must be delivered in sufficiently large doses. This is demonstrated by a dataset of 44...

Debris-flow initiation promoted by extension of a slow-moving landslide

Mark E. Reid & Dianne L. Brien
The dynamics of slow landslide motion can predispose oversteepened and extended slide regions to debris-flow initiation. For more than 20 years, our real-time monitoring, combined with repeat high-precision GPS surveys, of the Cleveland Corral landslide complex, California, USA, reveals that debris flows initiate from slow-moving kinematic elements of this complex. Different slide elements move in different wet years, and all remain dormant in dry years. To explore controls on landslide- element kinematics, we use triaxial...

Introducing Primo VE: streamline back-end administration

Laura Guy
You’ve already seen the new Primo user interface, but have you considered the benefits of combining Primo VE, a brand-new deployment model for Primo, with the new Primo UI? Primo VE provides unified back office management of Primo and Alma, resulting in a reduction of duplicated administrative processes and providing seamless publishing processes, real-time discovery of records created in Alma, and the task-oriented configuration and setup that many libraries already enjoy for other library workflows...

Nanotechnology, ethics and policy education: research and pedagogy

Carl Mitcham, Corinne E. Packard, Laura Heller, Derrick Hudson, Cortney Holles, Wang Nan, Zhu Qin, Jason Delborne, Jennifer J. Schneider & Sandra Woodson
This panel discussion on the creation of interdisciplinary modules about the social, ethical, environmental, and economic impact of nanotechnology was presented in three parts: the background of federal support for nanotechnology research; the pedagogy, practice and outcomes of the course modules and faculty workshop; and a review of the literature on social justice and ethics in nanotechnology with respect to belief systems and underrepresented groups. The presentation was delivered at the 2013 Association for Practical...

Numerical study of debris flows in presence of obstacles and retaining structures: a case study in the Italian Alps

Marina Pirulli, Mario Manassero, Carmine Terrioti, Alessandro Leonardi & Giulia La Porta
Debris flows are one of the most frequent mass movement processes and occur in all regions with steep relief and at least occasional rainfall. Their high flow velocity, impact forces, and long runout, combined with poor temporal predictability, cause debris flows to be one of the most hazardous landslide types. An essential aspect of debris-flow risk management is the design of mitigation measures, which reduce the existing risk to an accepted level of residual risk,...

ADMIRE: Autonomous Dam Monitoring with Integrated Real-time Evaluation

Kerri Stone & Tracy Camp
Dams have a large impact on public safety in the United States. Dam failures are far reaching and may result in loss of property, loss of life, and loss of water storage. Despite this fact, dam inspections occur infrequently and are performed unevenly across the structure. As such, current dam monitoring practice is often incapable of detecting internal erosion - a primary failure mode in dams. The inability to detect internal erosion results in increased...
