Climate Resilience: Examination Of Revised Heat Transfer Models In The Enhanced Integrated Climatic Model For Pavement Temperature Prediction, Austin Michael Jarrell

Theses, Dissertations and Capstones

The Mechanistic Empirical Pavement Design Guide (MEPDG) is commonly referenced as the state-of-the-practice for the analysis and design of new and rehabilitated pavement assets. The Enhanced Integrated Climatic Model (EICM) incorporated within the MEPDG is a well-recognized and standardized method for estimating temperature profiles in pavements; temperature is a portion of the climate inputs in the MEPDG. Many have already begun to convert atmospheric temperature predictions from externally based climate models into the MEPDG to create robust designs for climate change. As pavement designers and researchers seek robust solutions while formulating resilient pavement designs, it is likely that the EICM …

Energy & Carbon Neutral Nyc, Evan Banks, Elena Zimareva, Elena Malysheva

Publications and Research

In 2016, the world's leading countries signed the Paris Agreement which focused on reducing anthropogenic climate change on the planet. On May 2019, New York State and New York City declared its own ambitious goals aimed at decarbonizing the city and restricting the state’s energy use to relying completely on renewables.

Some of these goals specifically target infrastructure in the city since estimates cite buildings as accounting for nearly 70% of New York’s energy use. The main law of New York’s Climate Policy, Local Law 97, requires all buildings over 25,000 sq ft to reduce their CO2 footprint by 40% …

Comparative Study Of One Parameter Budyko Model Index And The Scs Curve Number, Cihad Ayberk Doner

LSU Master's Theses

This study investigates two water balance models from different levels of complexity to recognize the impacts of climate change on water resources. The main objective is to examine the capacity of future runoff calculations of a parsimonious simple water balance model compared to a more complex model under the climate change variables. The selected water balance models are the simple one-parameter Budyko-type model using the Zhang’s equation with single parameter (a) and the more complex model (HELP3) applying Soil Conservation Service (SCS) curve number method to calculate future runoff predictions. The study has a twofold focus, first on explaining the …

Simulation And Prediction Of The Groundwater Level In The Surrounding Area Of The Nebraska Management System Evaluation Area Site In Central Nebraska., Cesar Augusto Gomez Peña

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

An efficient water budget is necessary to develop sustainable practices in irrigated lands and determine future trends. Despite a lack of detailed knowledge, climate change is found to profoundly influence groundwater resources through changes in groundwater recharge, groundwater elevation, and groundwater flow processes. Prediction of the groundwater level (GWL) under a changing climate is essential to improve agricultural management.

The goal of this research is to predict the GWL from 2056 to 2060 in the surrounding area of the MSEA. In order to achieve the target, the first research task is to develop a groundwater flow model and then simulate …

Evaluation Of Future Climate Change Impact On Aquatic Ecosystem And Health Using Lm3-Tan Model In South Korea, Jin Wan Lee, Chung Gil Jung, So Ra Ahn, Seong Joon Kim

International Congress on Environmental Modelling and Software

Climate change could be one of the main threats faced by aquatic ecosystems and freshwater biodiversity. Recently, LM3-TAN (Land Model 3 Terrestrial and Aquatic Nitrogen) land-based physical, biological, chemical processes model for South Korea was developed to assess the combined effects of direct human influences and future climate change on Aquatic Nitrogen cycling by Korea NIEL (National Institute of Environmental Research). The objective of this study is to analyse the relationship between stream water quality, water temperature, and Trophic Diatom Index (TDI) and Benthic Macroinvertebrate Index (BMI) determined by stream water quality factors. The TDI and BMI monitored 2 times …

Use Of Sacrificial Embankments To Minimize Bridge Damage From Scour During Extreme Flow Events, Matthew Willi Brand

Graduate College Dissertations and Theses

The leading cause of bridge failure has often been identified as bridge scour, which is generally defined as the erosion or removal of streambed and/or bank material around bridge foundations due to flowing water. These scour critical bridges are particularly vulnerable during extreme flood events, and pose a major risk to human life, transportation infrastructure, and economic sustainability. Climate change is increasing the intensity and persistence of large flow events throughout the world, further straining bridge infrastructure. Retrofitting the thousands of undersized and scour critical bridges to more rigorous standards is prohibitively expensive, and current countermeasures inadequately address the core …

Ontology Mapping In Semantic Time Series Processing In Climate Change Prediction, Bojan Božić, Jan Peters-Anders, Gerald Schimak

International Congress on Environmental Modelling and Software

In today's time series processing there is more and more a need for addressing diverse user groups interested in a specific domain with appropriate user tailored time series data. The complexity of time series (e.g. involved data from different data sources and/or domains, visualization and representation, etc.) is growing rapidly. As a consequence, it means that users need to find a path through the jungle of time series data. After we have presented our concepts for semantic time series filtering and enrichment of time series with meta-information and annotations (Božić et al., 2012), we are now going to present a …

Long-Term Evaluation Of Norris Reservoir Operation Under Climate Change, Joseph Patton Rungee Ii

Masters Theses

This study aimed to address the potential long-term effects of future climate change on the Tennessee Valley Authority’s (TVA’s) operation policy for Norris Reservoir. The Community Earth System Model 1.0 (CESM1.0), a general circulation model (GCM) accessible through the Intergovernmental Panel on Climate Change’s (IPCC’s) Coupled Model Intercomparison Project Phase 5 (CMIP5), with the Representative Concentration Pathway 4.5 (RCP4.5) was used to obtain projected precipitation and temperature data for three future climate scenarios, 2030’s, 2050’s, and 2070’s. Three hydrologic models were individually calibrated on 30 years of observed runoff data and combined utilizing linear programming to consider the strengths of …
