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...

Conceptual framework for assessing disturbance impacts on debris-flow initiation thresholds across hydroclimatic settings

Benjamin B. Mirus, Dennis M. Staley, Jason W. Kean, Joel B. Smith, Rick Wooten, Luke A. McGuire & Brian A. Ebel
The destructive and deadly nature of debris flows has motivated research into empirical rainfall thresholds to provide situational awareness, inform early warning systems, and reduce loss of life and property. Disturbances such as wildfire and land-cover change can influence the hydrological processes of infiltration and runoff generation; in steep terrain this typically lowers empirical thresholds for debris-flow initiation. However, disturbance impacts, and the post-disturbance recovery may differ, depending on the severity, nature, extent, and duration...

Investigating the metastabilities surrounding hydrogen hydrates for energy storage applications

Michelle Shebowich, Melissa Arias, Robert Gary Grim, Prasad Kerkar, Amadeu Sum & Carolyn Koh
Hydrogen hydrate in its most thermodynamically stable form, sII, holds a maximum 3.8 wt. % hydrogen, less than the 5.5 wt. % needed to meet the Department of Energy 2015 goal. This novel work explored H2 hydrate structure, occupancy, and metastability during seeding/templating and guest substitution to ultimately increase hydrogen storage capacity in hydrates. The phenomenon of templating was evaluated by mixing pre-formed hydrate of a desired structure with ice to propagate its structure with...

2014 Faculty Conference: emerging national concerns for higher education

Terence E. Parker
This presentation gives an overview of the current challenges to higher education, including the decline of state funding and the nationwide rise in tuition; shaping forces of the future such as accountability, enrollment competition, changing business practices, and compliance concerns; and the ways in which CSM is poised to respond to these challenges and forces as part of the ongoing effort to execute the long-term strategic plan.

2004 land cover maps with 30m and 50m spatial resolution

Nicolás Rodríguez-Jeangros, Amanda S. Hering, Timothy Kaiser & John E. McCray
SCaMF-RM fuses the information of six land intermediate to high resolution land cover products in the Rocky Mountains (RM) at two high spatial resolutions, 30 and 50 meters, and a yearly frequency for the period 1983 – 2012.

Mesoscale modeling of quantum yield in nanocrystalline devices

Samantha Irvin, Philip David Flammer, Mark Lusk, Joe Beach, Jao Van De Lagemaat & Peter Graf
A new solar material features silicon nanocrystals (nc-Si) within an amorphous silicon (a-Si) matrix. The efficiency with which photons are absorbed and converted to electric current depends on the size, orientation, volume fraction, and interface properties of nc-Si. This investigation has resulted in the development of a device level simulator which predicts quantum efficiency and voltage-current character for nc-Si/a-Si systems. These performance measures are calculated as functions of input photon energy. A number of different...
