The Hydrologic Responses of Semiarid Watersheds to the Cultivation of Switchgrass (Panicum virgatum L.)
Goldstein, Justin Chamoy (2013-12)Due in part to the very recent influx of federal and state policies promoting the development of ethanol as a gasoline additive, switchgrass (Panicum virgatum L.) has received much attention. Nevertheless, investigations ... -
INTELLIGENT CYBERINFRASTRUCTURE FOR BIG DATA ENABLED HYDROLOGICAL MODELING, PREDICTION, AND EVALUATION
Wan, Zhanming (2015)Most hydrologic data are associated with spatiotemporal information, which is capable of presenting patterns and changes in both spatial and temporal aspects. The demands of retrieving, managing, analyzing, visualizing, ... -
Machine Learning Predictions of Flash Floods
Clark III, Robert Allan (2016-08-12)This dissertation contains a literature review and three studies concerned with the development, assessment, and use of machine learning (ML) algorithms to explore automatically generated predictions of flash floods. The ... -
Making Satellite Sensors Better for Hydroclimatic Applications: Evaluation of NASA SMAP Soil Moisture Using Oklahoma’s Environmental Monitoring Network—MESONET
Xu, Chen (2017-12-15)Soil moisture, quantified as the ratio of liquid water to soil in volume or weight, is the measurement of the water that is held in the space between soil particles. Understanding the components of soil, particularly its ... -
Mapping and Analyzing Urban Growth: A Study to Identify Drivers of Urban Growth in West Africa
Adhikari, Pradeep (2016-05)Urban area expansion is one of the most powerful anthropogenic forces changing the earth‘s surface. Such changes are happening at much faster rates in African and Asian cities. Several interconnected but distinct processes ... -
MOISTURE SOURCES FOR FLASH FLOODS IN THE UNITED STATES
Erlingis Lamers, Jessica (2017-12)This dissertation uses backward trajectories derived from North American Regional Reanalysis data for 19,253 flash flood reports published by the National Weather Service to assess the nonlocal contribution of the land ... -
MULTI-SCALE REMOTE SENSING OF OPEN SURFACE WATER BODY AREA AND QUALITY
Zou, Zhenhua (2019-05-10)Water is one of the most important resources for life. Climate change and climate variability have caused dramatic variations and significant trends in surface water resources, while global population growth and increased ... -
A NEW RESEARCH METHOD TO EVALUATE THE IMPACT OF WET RADOMES ON DUAL-POLARIZED WEATHER RADARS AND COMMUNICATION SYSTEMS
Mancini, Alessio (2018-12-14)The purpose of this dissertation is to provide a detailed study of the effect of water accumulated on wet radomes. To accomplish this goal, a novel method to evaluate the impact of wet radomes on dual-polarized weather ... -
OPTIMAL DESIGN OF A CONVECTION-ALLOWING ENSEMBLE FROM A MODEL ERROR PERSPECTIVE
Duda, Jeffrey (2016-05-13)As computer technology continues to improve, resources are becoming increasingly available for running an ensemble of NWP simulations with sufficient resolution that convection parameterization is no longer needed and ... -
Optimal Design of a Multi-scale Ensemble System for Convective Scale Probabilistic Forecasts: Data Assimilation and Initial Condition Perturbation Methods
Johnson, Aaron (2014-12-12)This dissertation research was undertaken to better understand the optimal design of convection-permitting storm-scale ensemble forecast (SSEF) systems that resolve features ranging from synoptic to convective scales. The ... -
REAL TIME MONITORING OF SLOPE STABILITY IN EASTERN OKLAHOMA
Cerato, Amy B.; Hong, Yang; Yu, Xiado; He, Xiaogang; Tabet, Wassim (2014-1)There were three primary objectives of the proposed research. The first was to establish a comprehensive landslide database, the second was to create a first- cut regional landslide map and the third was to relate safe and ... -
Remote Sensing of Hydrologic Variables in Rivers
Khan, Muhammad Mushfiqur (2020)The use of a “rating curve”, an empirical relationship between water depth in a river and the volumetric flux of water, or discharge, is subjected to uncertainty in data extrapolation, complexity due to changes in channel ... -
Risk-based evaluation and management of cyber-physical-social systems during pandemic crisis
Soltanisehat, Leili (2022-08)This research focuses on risk-based evaluation and management of cyber-physical-social systems during a pandemic crisis. The ongoing novel coronavirus (COVID-19) epidemic has caused serious challenges for the world’s ... -
Theoretical analysis of and bias correction for planar and cylindrical polarimetric phased array weather Radar
Lei, Lei (2014-08-15)Planar or Cylindrical Phased Arrays are two candidate antennas for the future polarimetric weather radar. These two candidate antennas have distinctly different attributes when used to make quantitative measurements of the ... -
TOTAL WATER LEVEL MODELING IN THE NORTH CAROLINA COASTAL PLAIN: COMPARING ADCIRC AND HEC-RAS
Bush, Samuel (2017-12-15)The purpose of this Master’s thesis was to develop and compare an ADCIRC and ADCIRC/HEC-RAS paired model for the purpose of total water level forecasting using the Tar River and Pamlico Sound area as a test case. ADCIRC ... -
TOWARDS IMPROVED QPE BY CAPITALIZING GROUND- AND SPACE- BASED PRECIPITATION MEASUREMENTS
Wen, Yixin (2015-05-08)There are primarily two types of weather radar systems offering precipitation measurements covering relatively large areas: (1) Ground-based Radar (GR) networks such as the NEXRAD and (2) Spaceborne radars onboard ... -
Use of small unoccupied aerial system multispectral imagery to address optical and non-optical water quality parameters in watershed restoration
