Tectonic and lithologic controls on bedrock channel profiles and processes in coastal California
[1] Recent theoretical models suggest that topographic characteristics of bedrock channels are products of interactions among tectonics, substrate resistance, and the climatically modulated erosive ability of the river. The degree to which these factors influence the form of channel profiles is poorly quantified at present. Here we investigate bedrock channels developed across the southern flan...
متن کاملTectonic Controls on Reservoir Permeability in the Dixie Valley, Nevada, Geothermal Field
To determine factors controlling permeability variations within and adjacent to a fault-hosted geothermal reservoir at Dixie Valley, Nevada, we conducted borehole televiewer observations of wellbore failure (breakouts and cooling cracks) together with hydraulic fracturing stress measurements in six wells drilled into the Stillwater fault zone at depths of 2-3 km. Measurements in highly permeabl...
متن کاملLithologic and Tectonic Controls on Bedrock Channel Form at the Northwest Himalayan Front
Recognition that channel form reflects a river's ability to erode rock has spawned stream-power models that estimate patterns of incision by approximating energy dissipation within a channel. Most commonly, these models assume channel width exponentially scales with drainage area, in part, because drainage area is easily extracted from digital elevation models (DEMs). However, this assumption i...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولMicroseismicity , stress , and fracture in the Coso geothermal field , California
Microseismicity. stress, and fracture in the Coso geothermal field are investigated using seismicity, focal mechanisms and stress analysis. Comparison of hypocenters of microearthquakes with locations of development wells indicates that microseismic activity has increased since the commencement of fluid injection and circulation. Microearthquakes in the geothermal field are proposed as indicato...
