Impacts Of Climate Change On The Evolution Of The Electrical Grid, Melissa Ree Allen

Doctoral Dissertations

Maintaining interdependent infrastructures exposed to a changing climate requires understanding 1) the local impact on power assets; 2) how the infrastructure will evolve as the demand for infrastructure changes location and volume and; 3) what vulnerabilities are introduced by these changing infrastructure topologies. This dissertation attempts to develop a methodology that will a) downscale the climate direct effect on the infrastructure; b) allow population to redistribute in response to increasing extreme events that will increase under climate impacts; and c) project new distributions of electricity demand in the mid-21^st century.

The research was structured in three parts. The first …

Coupled Simulation Of Human-Driven And Natural Land Cover Change In The Front Range Corridor, Co, Zhihua Liu, Michael C. Wimberly, Aashis Lamsal, Terry L. Sohl, Todd J. Hawbaker

International Congress on Environmental Modelling and Software

The Colorado Front Range Corridor is a mixture of urban, agricultural, grassland, and diverse forest types, making it an ideal natural laboratory to investigate feedbacks and interactions of coupled human and natural systems. We explored future scenarios of human-driven land use change and natural vegetation dynamics using the CHANGE model, which integrates a demand-allocation land use change module, a succession module for natural vegetation dynamics, and a spatially explicit fire initiation and spread module. We used the model to project landscape change over an approximately 48000 km² study area from 2005 through 2050 under A2 and B1 emission scenarios. …

An Overview Of The Nevada Climate Change Portal, Sergiu Dascalu, Frederick C. Harris Jr., Michael Mcmahon Jr., Eric Fritzinger, Scotty Strachan, Richard Kelley

International Congress on Environmental Modelling and Software

Created with support from an NSF EPSCoR Research Infrastructure Improvement (RII) grant completed in 2013, the Nevada Climate Change Portal (NCCP) serves as a cyberinfrastructure hub that provides data and computing resources for scientists studying the effects of climate change in Nevada. In particular, the NCCP has been designed for data acquisition, storage, access, and processing in support of long-term assessment of climate variability in Nevada and its impact on the state’s ecological and hydrological systems. The NCCP also serves as a central repository of climate-related information for other stakeholders, including educators, students, and the public. In this paper we …

An Integrative Modeling Framework To Evaluate Wheat Production Systems: Fusarium Head Blight, Willingthon Pavan, José Maurício Cunha Fernandes, Alexandre Lazzaretti, Josué Toebe, Jorge Luis Bavaresco, Alex C. Ruane, Rodrigo Yoiti Tsukahara

International Congress on Environmental Modelling and Software

This paper describes a practical, integrated, web-based and user friendly analysis tool for crop model users that provides quality control of input data, tracks user selections in model parameterization, and enables visual analysis of model outcomes using a single graphical user interface. This allows the user to undertake numerous steps in crop modeling and analysis in a seamless and integrated environment. The analysis and visualization components of the system were enabled utilizing R (pl/r) and the robustness of the underlying data structures and coupling point between crop and disease models were achieved through use of PostgreSQL database management system. The …

Water At The Centre Of Environmental Issues – Research At The Ucd Dooge Centre For Water Resources Research, Zeinab Bedri, Eva M. Mockler, Michael Bruen, Yaqian Zhao, Pj Purcell, John O'Sullivan, M. Alsaji, Aisling Corkery, Liam Doherty, M. Dzakpasu, M. Martins, A. Rymszewicz, L. Willuwet

Conference papers

Since 1988, the UCD Dooge Centre for Water Resources Research has been conducting research in a wide range of water topics including hydraulics, hydrology, coastal dynamics and wastewater with an emphasis on multi-disciplinary collaboration. This paper presents an overview of this research, both past and present, and provides an outlook to the future research directions of the Centre.
