Built open field : observations and projections
… and the ground? How do dimensions structure the field? How do they generate movement, change,continuity, discontinuity. transparency, alternations ...... ? This thesis attempts to answer these few basic questions. Basic in that they all relate to an understanding of organization. The premise is …

Integration of Numerical Modeling and Field Observations of Deep Excavations
… the soil constitutive behavior directly from field measurements of two excavation case histories. SelfSim is able to extract sufficient information on soil behavior to capture measured excavation response in multilayer soil profiles. The analyses demonstrate that the proposed SelfSim framework …

Field observations and numerical model simulations of a migrating inlet system
… and an inlet migrating 2.5 km in ~7 years. A field-verified Delft3D numerical model developed for this system is used to examine the hydrodynamics in the nearshore and their effect on the migrating inlet. An initial numerical experiment showed that the observed 70⁰ tidal modulation of wave …

Field observations of the early-age behavior of jointed plain concrete pavements
… by literature review, laboratory tests and some field collected data. The large joints were believed to develop at early-ages of the slabs curing (within the first 48 hours). The early-age stress developments were found controlled by slab temperature history, material property development and …

Water Chestnut: Field Observations, Competition, and Seed Germination and Viability in Lake Ontario Coastal Wetlands
… this exotic invasive plant more thoroughly, field observations and experiments were performed. The field observations were made in Lake Ontario coastal wetlands during the 2014 growing season. Percent coverage, time of flowering, time of seed production, and co-occurring species were noted. A …

Field Observations and Numerical Simulations of Groundwater Dynamics Within Cabretta Island, A Georgia Barrier Island
… response to rapid population growth. I present field and numerical results that 1) provide a better understanding of groundwater dynamics during calm weather periods, and 2) investigate the impacts of high energy storms on groundwater properties within Cabretta Island, a barrier island in …

Malaria transmission around the Koka Reservoir in Ethiopia : field observations, model predictions, and strategies for prevention
… in Africa based on extensive multi-year field surveys around the Koka Reservoir in Ethiopia. A mechanistic malaria transmission model, HYDREMATS (Hydrology, Entomology, and Malaria Transmission Simulator), was extended to simulate the hydrology influenced by a reservoir system and to …

Kinematics and dynamics of salt tectonics in the Paradox Basin, Utah and Colorado : field observations and scaled modeling
… salt withdrawal and dissolution. Combined field mapping and physical modeling were used to investigate salt tectonics in the Paradox Basin, Utah and Colorado. In the scaled physical models, prograding sediment wedges expelled the underlying salt basinward by differential loading. Wedges …

The hydrology of malaria : field observations and mechanistic modeling of the malaria transmission response to environmental climatic variability
… The model is validated with several years of field data collected from Banizoumbou village in southwestern Niger. Simulations of the 2005 and 2006 rain seasons in Banizoumbou using measured meteorological data successfully reproduce the observed interannual variability in malaria vector …

Field Observations and Modeling of the 1957 Earthquake and Tsunami on the Islands of the Four Mountains, Aleutian Islands, Alaska
… (presented here). Combined with other nearfield observations of 22 m on Umnak and 18.5 m on Unalaska (USGS), our measurements establish the 1957 tsunami as a significant tsunami in the 20<sup>th</sup> century. Through modeling this earthquake and tsunami and comparing simulations to …

Mapping the interstellar magnetic field: Observations of the Goldreich-Kylafis effect towards late-type evolved stars and star-forming regions
Mapping magnetic fields is the key to resolving the yet unclear physical picture of circumstellar magnetic fields in both late-type evolved stars and star-forming regions. Observations of linearly polarized molecular line transitions arising from the Goldreich-Kylafis (G-K) effect provide valuable …

Chronic effects of single intra-peritoneal injection of endosulfan on rainbow trout (Oncorhynchus mykiss) and field observations of caged rainbow in Oshawa Creek
The organochlorine pesticide endosulfan has been shown to be highly toxic to fish and there is some evidence to support that it may act as an endocrine disrupting chemical. Juvenile rainbow trout (Oncorhynchus mykiss) were caged at 4 sites in Oshawa Creek during the fall and spring of 2008 and 2009 …

Water quality and hydrological assessment and modeling of bioretention basins in tropical cities
… in Singapore. We then use a combination of field observations and model simulations to recommend practical engineering strategies to design and manage bioretention basins in the tropics. First, field observations on water quality performance in six sampled events show that removal targets …

A case study investigating perceptions on process and outcomes in applying the Alexander Technique in vocal production
… documentation in student practice journals, and field observations. Data were analyzed, determining consistent trends between all the participant's perceptions of the processes involved in applying Alexander Technique in vocal production. These primarily involved improving body awareness through …

The Response of Buildings to Excavation-Induced Ground Movements
The results of physical model tests and field observations are combined with the results of parametric studies, and together they are used to provide a background for developing guidelines for controlling building damage and to develop a procedure for estimating building damage due to …

Imaging in karst terrain using the Electrical Resistivity Tomography (ERT) and Multi-Channel Analysis of Surface Waves (MASW) methods
… from those that were mostly of 'natural' origin. Field observations and air photographs were used for this purpose.</p><p>Herein, seven ERT profiles are presented. Five (5) of the low resistivity bedrock anomalies identified on these ERT profiles are classified as primarily 'man-made'; the other …
