Exploring the effects of uncertainty in hydrologic modeling and reconciling spatiotemporal data gaps at the continental scale
… in many parts of the conterminous United States (CONUS). Classic model validation studies are insufficient in describing model skill over such large extents due to limitations in data availability. Further, models are increasingly more expensive to operate and analyze due to higher levels of …

Trends and projections of extreme precipitation over the contiguous United States
… projected trends in contiguous United States (CONUS) extreme precipitation events were examined in CMIP5 models, using, as a metric, the Extreme Precipitation Index (EPI) and a similar method based on the EPI. An increasing trend over the CONUS was found in the EPI, with variation among seven …

Temporal Changes in Surface Water Availability: Patterns of Seasonal Shift on Water Stress in the Conterminous US Under a Changing Climate
… that one or another part of the conterminous US (CONUS) is expected to experience an annual deficit or a surplus in runoff. Further studies have looked at changing patterns over the CONUS as a whole. Other research has focused on a particular season. This work addresses a gap in the research by …

Understanding the Role of Vegetation Dynamics and Anthropogenic induced Changes on the Terrestrial Water Cycle
… precipitation over the contiguous United States (CONUS). The combined effects of LCC and irrigation indicated a significant drying over the CONUS, with increased duration and decreased intensity of dry spells, and reduced duration, frequency, and intensity of wet spells. Irrigated cropland areas …

Understanding drought propagation and its implications for drought management
… in different regions of the contiguous US (CONUS), and to provide a holistic framework for the assessment of drought impacts on natural and human systems. The first part of the dissertation focuses on meteorological droughts, which are defined as periods with deficient rainfall. The spatial …

Vulnerability of U.S. river basins to water shortage over the 21st century
… across the conterminous United States (CONUS) over the 21st century. To achieve this goal, first, the effects of climate change on the regional hydroclimatology of U.S. river basins were assessed over the 21st Century to determine regions with prolonged dry or wetting periods. This …

Large-scale Process-based Urban Hydrological Modeling Framework
… and larger, e.g., Conterminous United States (CONUS), scales, first, we evaluated our framework at nine representative urban watersheds in Houston, Texas. We gained crucial insights into the capacity and limitations of BUSNs during flood events, underlining the importance of diverse flood …

Quality control and analysis of an updated wind gust data set in the United States
… stations across the Continental United States (CONUS) and explores limitations and implications for long return period wind speed estimation. In total, the data set contains more than 17.9 million peak wind gusts, including nearly double the station-years available compared to the data set used …

Water requirement for biorefinery to meet the renewable fuel standard in the contiguous United States
… water is needed in the Contiguous United States (CONUS) to convert feedstocks to biofuels and the associated impacts on local water availabilities. This study addresses this issue with the most up-to-date data of feedstock, water availability, and water requirements for biorefinery technologies. …

Developing proxy radar data with the aid of cloud-to-ground lightning for a nowcasting system
… up to date nowcast information over the entire CONUS for efficient operations in the National Airspace System. In areas of degraded or no radar coverage, cloud-to-ground lightning (provided by the National Lightning Detection Network) can provide valuable information through the creation of …

Sampling, Detection, and Characterization of Endogenous Peptides
… labs around the globe. Over 600 species of Conus exist, each having a vast array of toxins evolutionarily developed to target specific ligand and ion gated channels. Here I describe the first peptides characterized from the novel species of Conus californicus. Next, I will describe how LC-MS …

An examination of geographic patterns of soil climate and its classification in the U.S. system of soil taxonomy
… soil moisture map of the conterminous U.S. (GEN-CONUS). GEN-CONUS and the 1994 map were compared to each other and to two sets of weather station data from years 1961 to 1990 and years 1971 to 2000 (National climate data center, NCDC). Agreement between GEN-CONUS and the 1994 map was 75.6%. …

Modeling of Airline and Passenger Dynamics in the National Airspace System (NAS)
… regions. The international enplanements from the CONUS to each world region are modeled as a function of GDP and GDP per capita of both the United States and the specific region. A dummy variable is also used to account for the effects of September 11, 2001. The total number of international …

ADVANCING NATIONAL-SCALE HIGH-RESOLUTION CROP MAPPING USING REMOTE SENSING
… maps across the Contiguous United States (CONUS) from 2019 to 2022. By comparing these maps to the widely used 30-m products, I quantified the advantages of higher-resolution crop mapping, showing that 10-m maps reduced 30-m mixed pixels by approximately 8% for maize and 9% for soybean …

A Better Tropospheric Aerosol Analysis and Forecast Using Data Assimilation and Coupled Modeling
… in the O3 chemical production regime over the CONUS in the summers of 2011, 2014, and 2017, top-down emissions of NOx and NMVOCs were estimated by using tropospheric NO2 and total HCHO columns from OMI. The inversion suggested 2.33 – 2.84 times higher NOx over the CONUS and 0.28 – 0.81 times …

DEVELOPMENT AND EVALUATION OF TECHNIQUES FOR HYDROCLIMATOLOGICAL CHARACTERIZATION
… to trends in 7-day low flow across eastern CONUS. Next, I investigate minimum delay embedding dimension (De) of streamflow: a nonlinear metric of complexity hypothesized to reflect the form of precipitation generating runoff. Although streamflow De negatively correlates with fraction of …

Renforcement de piles de ponts au moyen de tissus collés en aramide contre l'impact de véhicules lourds
Dans certains pays d'Europe, spécialement en France et au Royaume-Uni, plusieurs accidents impliquant des véhicules lourds ont mis en évidence qu'un grand nombre de piles de ponts situées en bordure d'autoroute ne répondent plus aux exigences des normes actuelles. Il est donc impératif de trouver …
