Mountainous watersheds in semi-arid regions are complex hydrologic systems. To critically evaluate the hydrological processes, high resolution spatio-temporal information is necessary. Also, calibrating and validating a watershed-scale model is necessary to enable our understanding of the water balance components in the gauged watersheds. The distributed Soil Water Assessment Tool (SWAT) hydrologic model was applied to a research watershed, the Dry Creek Experimental Watershed (DCEW), near Boise Idaho to investigate its water balance components both temporally and spatially. Daily streamflow data from four streamflow gauges were used for calibration and validation of the model. Monthly estimates of streamflow during the calibration …

This paper explains and evaluates the potential and limitations of conducting Cross-Well Radar (CWR) in sandy soils. Implementing the experiment and data collection in the absence of any scattering object, and in the presence of an acrylic plate (a representative of dielectric objects, such as DNAPL (dense non-aqueous phase liquid) pools, etc.), as a contrasting object in a water-saturated soil is also studied. To be able to image the signature of any object, more than one pair of receiving and transmitting antennas are required. The paper describes a method to achieve repeatable, reliable, and reproducible laboratory results for different transmitter-receiver …

Close agreement between theory and experiment is critical for adequate understanding and implementation of the Cross-Well Radar (CWR, otherwise known as Cross-Borehole Ground Penetrating Radar) technique, mentioned in a previous paper by the authors. Comparison of experimental results to simulation using a half-space dyadic Green’s function in the frequency domain requires development of transfer functions to transform the experimental data into a compatible form. A Channel Transfer Function (CTF) was developed to avoid having to model the transmitting and receiving characteristics of the antennas. The CTF considers electromagnetic (EM) wave propagation through the intervening media only (soil in this case), …

Boise State University is in the process of transforming from a historically "commuter" campus into a metropolitan research university which includes a growing residential culture (currently 8% of students live in residence halls). First time, full time freshmen age 18 or younger have increased from 61% of the incoming class in 2000 to 72% of the incoming class in 2008. To support our growing residential culture, University Housing, in cooperation with six academic colleges, began the Residential College (RC) program in 2004. Key among the five current RC communities is the College of Engineering. The Engineering Residential College (ERC) admits …
Hydrological Behavior Of Grasslands Of The Sandhills Of Nebraska: Water And Energy Balance Assessment From Measurements, Treatments And Modeling, Venkataramana Sridhar, David A. Wedin

Understanding energy and water balance processes in the Sandhills is crucial to assess the land-atmosphere feedback effects. The Sandhills located in western Nebraska covers a vast grassland ecosystem with limited variability in vegetation and soil. However, the combined effect of topography, land cover and micrometeorology by subjecting the land surface to various disturbances and treatments is rarely studied. The NOAH Land Surface Model was used to estimate net radiation, latent, sensible and ground heat fluxes as well as water balance components for two growing seasons between 2005 and 2006 in various plots at the Grasslands Destabilization Experimental site where these …
