Evaluating Climate Change Scenarios For Regional Hydrological Management In Mountainous Semi-Arid Environments, Agustín Millares, Javier Herrero, Cristina Aguilar, María José Polo

International Conference on Hydroinformatics

Snow processes play a relevant role in semi-arid mountainous basins where snowmelt dynamics conditions the availability of water resources. In such environments, many rivers flow during the dry season due to the water storage in the snow cover while heavy rainfall events sporadically trigger severe flood events. These particularities confer to these areas special interest due to their high sensitivity in the hydrological response against changes in the meteorological conditions. This issue could be critical in many regions of the world linked to semi-arid mountain areas (e.g., the Atlas Mountains, Andean Cordillera,…) and presents a real challenge for future modifications …

A Complex Adaptive Systems Approach To Simulate Interactions Among Water Resources, Decision-Makers, And Consumers And Assess Urban Water Sustainability, Alireza Mashhadi Ali, M. Ehsan Shafiee, Sankarasubramanian Arumugam, Emily Zechman Berglund

International Conference on Hydroinformatics

The balance between water supply and demand for urban water resources is threatened by population growth, land use changes, and climate change. Interactions among environmental resources, infrastructure, societal norms, and management decisions create complexity and increase the unpredictability of the dynamics of water availability. This research develops a sociotechnical framework to simulate interactions among technical and social systems and assess urban water sustainability. An agent-based model (ABM) is implemented to simulate a community of heterogeneous households as agents. The ABM is coupled with a hydrological watershed model, a water reservoir model, and climate change projections. The increase in the number …

Delaware Reservoirs’ Drought Risk Assessment: A Paleo View, Naresh Devineni, Gokce Ceylan

International Conference on Hydroinformatics

The Delaware River provides half of New York City's drinking water, is a habitat for wild trout, American shad and the federally endangered dwarf wedge mussel. It has suffered four 100‐year floods in the last seven years. A drought during the 1960s stands as a warning of the potential vulnerability of the New York City area to severe water shortages if a similar drought were to recur. The water releases from three New York City dams on the Delaware River's headwaters impact not only the reliability of the city’s water supply, but also the potential impact of floods, and the …

Quantifying Gcm Simulation Uncertainty And Incorporating Into Water Resources Assessment, Fitsum Markos Woldemeskel, Ashish Sharma, Bellie Sivakumar, Rajeshwar Mehrotra

International Conference on Hydroinformatics

Rainfall and temperature, simulated using Global Climate Models (GCMs), serve as key inputs for hydrological models in studying catchment responses to climate scenarios. GCM simulations of rainfall and temperature, however, are uncertain due to model structure, scenarios and initial conditions, which results in biased outcomes if used for hydrological models without due consideration of the uncertainties. In this study, we develop a novel uncertainty metric, square root error variance (SREV), to quantify uncertainties involved in GCM rainfall and temperature simulations as well as illustrate its application for water resources assessment. The uncertainty metric involves converting multiple GCM simulations into their …

Hydrological Impacts Of Climate Change – Challenges, Uncertainty And Limitations, Shreedhar Maskey, Yurong Hu, Anshul Agarwal, Dinesh Bhatt

International Conference on Hydroinformatics

How climate change impacts water resources in the future is an important question that all hydrologists want to have an answer. Climate prediction scenarios are available from many Global Circulation Models for the 21st century. These prediction datasets are typically used as input to a hydrological model for simulating impacts on hydrology, particularly river runoff, evaporation, and storage changes. Because hydrological models are usually run on a much smaller resolutions than climate models, the climate prediction datasets are usually downscaled to represent local climate for using in a hydrological model. The uncertainty in the GCMs, downscaling and hydrological models makes …

Propagation Characteristics Of Density Currents And Implications To Pollutant Transport In A Stratified Reservoir, Xin Sun, Yan Xu, Tinglin Huang, Xiao Tang

International Conference on Hydroinformatics

With global warming, the frequency and intensity of extreme rainfall events were predicted to change more dramatically in the near future while the amount of total precipitation will change slightly. Large volume of turbid inflow will enter the source water reservoir after a heavy rainfall, and evolve in various types of density currents depending on the density difference between the inflow and background water. Density currents play an important role in the thermal structure and pollutant transport in the reservoir. Understanding the behaviors of density current is fundamental to study the changes of source water quality during the flooding season. …

In-Season Drought Monitoring: Testing Instrumentation And Developing Methods Of Measurement Analysis, Tyson Brant Raper

Graduate Theses and Dissertations

Soil moisture sensor use in crop production systems has the potential to give inference on plant water status for the purpose of irrigation scheduling and site-drought characterization. These processed measurements could serve as the framework on which to compile trial results across locations, thereby more accurately defining varietal yield response to drought. Still, the ability to characterize drought within a given field or initiate irrigations from these data hinge upon the ability of the instrument to characterize soil moisture at the sampled point and extrapolate that information across the landscape and time. Therefore, the objectives of this research were to: …

Improving Drought Management For Transboundary River Basins In The United States Through Collaborative Environmental Planning, Crystal J. Bergman

School of Natural Resources: Dissertations, Theses, and Student Research

Increasing demand for water and the uncertainty of climate change have put pressure on the global water supply, presenting one of the greatest challenges of the 21^st Century for human development. Drought is a natural hazard that further compromises water supply and increases competition among water use sectors. These challenges confirm the need for comprehensive water supply and drought planning. Planning for water, however, is often conducted within political boundaries that are not consistent with the water resource’s natural boundaries, which can result in conflict. Collaborative environmental planning is a sub-discipline of planning that can address the occurrence of …
