|
 | The properties of an atmospheric pressure plasma jet (APPJ) are examined in a single-cell dielectric capillary configuration. In contrast to some other flow-driven APPJs, this stable, cold plasma jet is electrically driven, composed of rapidly propagating ionization fronts with speeds of the order of 107 sq cm. Using spatially and temporally resolved optical diagnostics, it is demonstrated that the plasma jet is initiated independent of the dielectric barrier discharge inside ... |

|
| Rivers pose one of the most challenging environments to quantify as they contain elements of both land and water. Their dynamical scales are small in size relative to traditional ocean processes, and are ever-changing in their position and character. To compound the problem, many riverine environments of interest to the U.S. Navy are inaccessible or denied and typically have very little, if any, known information. To address the operational needs ... |

|
| The need to simulate surface water flows in watersheds with diverse runoff production mechanisms has led to the development of the physically-based hydrologic model Gridded Surface Subsurface Hydrologic Analysis (GSSHA). GSSHA is a reformulation and enhancement of the two-dimensional, physically based model CASC2D. The GSSHA model is capable of simulating stream flow generated by a variety of sources, including runoff due to infiltration excess and saturated sources areas and seeps, ... |

|
 | A UHF RiverSonde system, operating near 350 MHz, has been in operation at Threemile Slough in central California, USA since September 2004. The water in the slough is dominated by tidal effects, with flow reversals four times a day and a peak velocity of about 0.8 m/s in each direction. Water level and water velocity are continually measured by the U.S. Geological Survey at the experiment site. The velocity is ... |

|
| The streamfunction-vorticity equations for two-dimensional cavity flow are solved by a new finite element method which uses finite spectral basis functions as shape functions for rectangular elements. Simulations for several cases with different Reynolds numbers are performed. Good agreement was obtained in the comparison between the present results with the bench mark solutions. |

| The Androscoggin River flooded the town of Canton, Maine in December 2003, resulting in damage to and/or evacuation of 44 homes. Streamflow records at the U.S. Geological Survey (USGS) streamflow-gaging stations at Rumford were used to estimate the peak streamflow for the Androscoggin in the town of Canton for this flood. The estimated peak flood streamflow at Canton was approximately 39,800 cubic feet, corresponding to an estimated recurrence interval of ... |

|
| The timing and location of streamflow in the San Pedro River are partially dependent on the aerial distribution of recharge in the Sierra Vista subwatershed. Previous investigators have assumed that recharge in the subwatershed occurs only along the mountain fronts by way of stream channel infiltration near the contact between the low permeability rocks of the mountains and the basin fill. Recent studies in other alluvial basins of the Southwestern ... |

| Stream channels in arid regions are subject to a wide range of hydrologic, hydraulic, and sedimentary conditions. These channels often are dry or have little streamflow most of the time, and the few flows that do occur can cause substantial changes to the channel and flood plain. Because floods in arid regions are often flashy, and many gaging stations are in remote areas, hydrographers must rely on indirect measurements of ... |

| We investigated the performance of a groundwater flow and solute transport model when different combinations of hydraulic head, seepage flux, and chloride concentration data were used in calibration of the model. Using additional calibration data, beyond traditionally-used head data, improved performance of the model during a test period separate from the calibration period. This confirms the merit of collecting seepage flux and concentration data, and using them together with head ... |

| Stratified flow over topography is examined in the context of its establishment from rest. A key element of numerical and steady state analytical solutions for large amplitude topographic flow is the splitting of streamlines which then enclose a trapped wedge of mixed fluid above the rapidly moving deeper layer. Measurements have been acquired which show that this wedge arises from small scale instabilities and mixing formed initially by the acceleration ... |
