Exploring the Hydroclimatology of Floods: From Detection to Attribution
Uncertainties in projected future flood risk and challenges of detecting signals of change from observations highlight the need to advance process understanding through linking hydrological extremes to large-scale climate drivers. In Ireland, recent years have highlighted vulnerability to flooding …

Trends and interannual variability in snowpack and spring season hydroclimatology in the southwestern United States
… and seasonal snowpack interact to affect spring hydroclimatology. Understanding snowpack-mediated spring soil moisture and how observed, current changes in the regional climate affect the snowpack-soil moisture relationship will provide important insights into the current and future hydrology of …

The Hydroclimatology of West Virginia Spatial and Temporal Trends and their Relationship with the North Atlantic Oscillation
Global air temperature has risen 0.74°C over the last 100 years, and is one of several factors influencing climate and streamflow variability at global, regional, and local scales. The North Atlantic Oscillation (NAO) is another important factor contributing to climate variability by …

Projecting Future Local Hydroclimatology: A Framework for Local Water Resource Planners in the Animas River Basin at Durango, Colorado
… water resources. Predicting future changes in hydroclimatology will provide a serious challenge for local water resource planners. The goal of this research was to project future changes in local winter and spring air temperature and precipitation along with impacts on stream flow for a typical …

DEVELOPMENT AND EVALUATION OF TECHNIQUES FOR HYDROCLIMATOLOGICAL CHARACTERIZATION
… are needed that can better characterize hydroclimatology and its influence on water partitioning without requiring extensive records in a stationary climate. First, I devise a temporal concentration index (TCI) for quantifying the clustering of precipitation events in time and compare it …

A small look at the big picture: linking geopotential height anomalies to paleofloods on the Snake River, Idaho and Oregon
<p>A combined paleoflood and flood hydroclimatology study on the Snake River in Idaho and Oregon suggests a link between floods and patters of geopotential height anomalies over the North Pacific Ocean. Examination of the paleoflood record in two 4-m (12 ft) tall terraces along the Hells Canyon …

Vulnerability of U.S. river basins to water shortage over the 21st century
… 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 analysis shows that U.S. river basins within the CONUS can be clustered into seven groups with unique …

An observing system simulation experiment for soil moisture measurements from the SMAP radiometer
… soil moisture knowledge has many applications in hydroclimatology, numerical weather prediction, flood forecasting, and human health. In this thesis, an observing system simulation experiment (OSSE) was used to study the error structure of radiometer measurements using two different retrieval …

A hydroclimatic assessment of the U.S. corn belt across spatial and temporal scales
… Two types of climate comprise the science of hydroclimatology: the climate as established by general global circulation patterns at specific locations on Earth (large-scale climate) and the climate established at Earth's surface resulting from the daily fluxes of radiant energy and water in …

Understanding the Effect of Climate and Hydrometeorological Extremes on Natural and Human-Induced Hydrosystems
… this dissertation focuses on investigating the hydroclimatology of natural and modified basins across the contiguous United States. It has three research objectives: (1) to explain flow alterations due to anthropogenic activities, especially dam operations, in modified basins and understand how …

Climatic and Anthropogenic Influences on Food and Water Security
… was intercompared. Findings indicate that both hydroclimatology and anthropogenic interventions, such as irrigation expansion, can have a significant influence on crop acreage dynamics. Furthermore, economic incentives for farmers to expand irrigation can potentially stem crop acreage losses. To …

Hydroclimate Drivers and Atmospheric Dynamics of Floods
… aspects to the growing literature on the hydroclimatology of floods and its impacts: 1) Global trends in the duration and frequency of observed floods, and their driving atmospheric teleconnection together with their impacts are revealed, 2) A comprehensive hydroclimate-informed framework …

Variation and Change in Daily Precipitation Extremes Across the United States Since the Mid-20th Century
Research indicates a warming global climate leads to change in the spatial and temporal characteristics of precipitation. Although precipitation is inherently variable through time and space, for some water-sensitive stakeholders, the evenness with which precipitation is distributed through a time …

Near Real-time Seasonal Drought Forecasting and Retrospective Drought Analysis using Simulated Multi- layer Soil Moisture from Hydrological Models at Sub- Watershed Scales
This study proposes a stratified approach of drought severity assessment using multi-layer simulated soil moisture. SWAT (Soil and Water Assessment Tool) models are calibrated for 50 watersheds in the South-Atlantic Gulf region of the Southeastern US and a high-resolution daily soil moisture …

Impacts of large-scale soil moisture anomalies on regional hydroclimate in southeastern South America
Advancing our understanding of the hydroclimate of southeastern South America (SESA) is imperative for a number of reasons. Within SESA is the La Plata River basin (LPRB), the second-largest river basin in South America. The LPRB includes a diverse array of ecosystems. The region is also …

Data-driven modeling of hydroclimatic trends and soil moisture: multi-scale data integration and decision support
The techniques and information employed for decision-making vary with the spatial and temporal scope of the assessment required. In modern agriculture, the farm owner or manager makes decisions on a day-to-day or even hour-to-hour basis for dozens of fields scattered over as much as a fifty-mile …
