Climate Change Impacts On Water Resources Of The Upper Blue Nile River Basin, Ethiopia, U. Kim, Jagath J. Kaluarachchi, V. U. Smakhtin
Civil and Environmental Engineering Faculty Publications
Climate change affects water resources availability of international river basins that are vulnerable to runoff variability of upstream countries especially with increasing water demands. The upper Blue Nile River Basin is a good example because its downstream countries, Sudan and Egypt, depend solely on Nile waters for their economic development. In this study, the impacts of climate change on both hydrology and water resources operations were analyzed using the outcomes of six different general circulation models (GCMs) for the 2050s. The outcomes of these six GCMs were weighted to provide average future changes. Hydrologic sensitivity, flow statistics, a drought index, …

Modeling Soil Depth From Topographic And Land Cover Attributes, Teklu K. Tesfa, David G. Tarboton, David G. Chandler, James P. Mcnamara
Civil and Environmental Engineering Faculty Publications
Soil depth is an important input parameter in hydrological and ecological modeling. Presently, the soil depth data available in national soil databases (STATSGO and SSURGO) from the Natural Resources Conservation Service are provided as averages within generalized land units (map units). Spatial uncertainty within these units limits their applicability for distributed modeling in complex terrain. This work reports statistical models for prediction of soil depth in a semiarid mountainous watershed that are based upon the relationship between soil depth and topographic and land cover attributes. Soil depth was surveyed by driving a rod into the ground until refusal at locations …

Data Collection Methodology For Dynamic Temperature Model Testing And Corroboration, Bethany T. Neilson, David King Stevens, S. C. Chapra, Christina J. Bandaragoda
Civil and Environmental Engineering Faculty Publications
This article describes a data collection approach for determining the significance of individual heat fluxes within streamswith an emphasis on testing (i.e. identification of possible missing heat fluxes), development, calibration and corroborationof a dynamic temperature model. The basis for developing this approach was a preliminary temperature modelling effort onthe Virgin River in southwestern Utah during a low-flow period that suggested important components of the energy balancemight be missing in the o riginal standard surface-flux temperat ure model. Possible missing heat fluxes were identi fied as bedconduction, hyporheic exchange, dead zone warming and exchange and poor representation of the amount of …

Energy Losses In Cross Junctions, Zachary B. Sharp, Michael C. Johnson, Steven L. Barfuss, William J. Rahmeyer
Civil and Environmental Engineering Faculty Publications
Energy losses occurring in pipe junctions have been studied for many years. Head loss coefficients (KK) are commonly used to characterize losses across elbows, tees, crosses, valves, and other pipe fittings. When accurate values of KK are used, the flow rate and corresponding total head at any location in a pipe network can be calculated. While KK is well defined for most pipe junctions and fittings, the literature has limited documentations of KK for crosses. This study was commissioned to determine KK for a wide range of flow combinations in a pipe cross with equal diameter pipes and varied flow …

Dynamic stability requirements for manned aircraft have been in place for many years. However, we cannot expect stability constraints for UAVs to match those for manned aircraft; and dynamic stability requirements specific to UAVs have not been developed. The boundaries of controllability for both remotely-piloted and auto-piloted aircraft must be established before UAV technology can reach its full potential. The development of dynamic stability requirements specific to UAVs could improve flying qualities and facilitate more efficient UAV designs to meet specific mission requirements. As a first step to developing UAV stability requirements in general, test techniques must be established that …

The Nature And Status Of Stem Professional Development: Effective Practices For Secondary Level Engineering Education, Rodney L. Custer, Jenny L. Daugherty
Reports of Center Studies
Recently engineering has emerged on the K-12 scene as a potentially important content area. However, K-12 teachers typically lack sufficient backgrounds to effectively integrate engineering into their classrooms. Thus teacher professional development is of critical importance. Although there have been several initiatives emerge to assist teachers in teaching engineering-related curriculum, there has been little empirical research generated. For example, little is known about best practices, engineering pedagogical content knowledge, or effective design principles for engineering professional development. Although there is a general consensus in the literature concerning a set of principles that differentiate effective teacher professional development (i.e., Garet, Porter, …

Reports of Center Studies
In recent years, there has been a growing interest in science, technology, engineering, and mathematics (STEM) education across the K-16 spectrum. While much of this interest has concentrated on science and mathematics, technology and engineering are emerging as authentic educational problem solving contexts, as well as disciplines in their own right at the K-12 level. Over the past 20 years, the technology education field has concentrated on defining and implementing a set of content standards, the Standards for Technological Literacy (ITEA, 2000) (STL), with mixed results. On a national scale, the field continues to evolve from its historical industrial arts …

A Theoretical Framework To Guide The Re-Engineering Of Technology Education, Todd R. Kelley, Nadia Kellam
Publications
Before leaders in technology education are able to identify a theoretical framework upon which a curriculum is to stand, they must first grapple with two opposing views of the purpose of technology education – education for all learners or career/technical education. Dakers (2006) identifies two opposing philosophies that can serve as a framework for technology education, both inspired by ancient Greece, with the works of Descartes and the birth of positivism. Later reappearing in Pascal’s writings of the mathematical mind, and finally with Rousseau in the mid 1700s, the theoretical arguments of academic verses vocational were established in education, and …
