Water Report

This report from the Indiana Climate Change Impacts Assessment (IN CCIA) applies climate change projections for the state to explore how continued changes in Indiana’s climate are going to affect all aspects of water resources, including soil water, evaporation, runoff, snow cover, streamflow, drought, and flooding. As local temperatures continue to rise and rainfall patterns shift, managing the multiple water needs of communities, natural systems, recreation, industry, and agriculture will become increasingly difficult. Ensuring that enough water is available in the right places and at the right times will require awareness of Indiana’s changing water resources and planning at regional …

In sub-Saharan Africa, maize is one of the most important staple crops, but long-term maize cropping with low external inputs has been associated with the loss of soil fertility. While adding high-quality organic resources combined with mineral fertilizer has been proposed to counteract this fertility loss, the long-term effectiveness and interactions with site properties still require more understanding. This study used repeated measurements over time to assess the effect of different quantities and qualities of organic resource addition combined with mineral nitrogen (N) on the change of soil organic carbon (SOC) contents over time (and SOC stocks in the year …

Prioritizing Proximity In Phasing Out Oil And Gas Extraction, Wyatt G. Sassman

Connecticut Law Review

To avoid the most catastrophic impacts of climate change, most of the world’s oil and gas reserves must remain in the ground. In the United States, this would require a dramatic phaseout of oil and gas extraction nationwide over the coming decades. How could we accomplish this? While recent legal scholarship emphasizes the importance of a just transition away from oil and gas extraction, little work has been done to navigate the legal, political, and equity hurdles associated with phasing out oil and gas extraction.

This Article seeks to start this conversation by offering one way to approach phaseouts of …

Western Kentucky University Stormwater Utility Survey 2023, Warren Campbell, Emily G. Davis

SEAS Faculty Publications

The main goal of this survey is to identify as many U.S. Stormwater Utilities (SWUs) as possible. Because many stormwater professionals do not have the time to respond to questionnaires, our primary method of identification was Internet searches. We searched key terms such as “stormwater utility”, “stormwater fee”, and “drainage fee”. We scoured online municipal codes such as Municode, AmLegal, Sterling, LexisNexis, General Code, and others. We searched through many city web websitesing to find utilities. We have also had many people contact me to update fees and identify new utilities. However, the data primarily comes from Internet sources and …

Estimation Of Quantitative Genetic Parameters Of The Eastern Oyster (Crassostrea Virginica) In The Gulf Of Mexico, Heather King

Master's Theses

The decline of natural oyster reefs in Gulf of Mexico (Gulf) states has stimulated the development of aquaculture to support the industry and restoration programs. Gulf habitats feature diverse salinity environments that may require oysters bred for habitat-specific optimal genetic characteristics. In this work, genetic parameters for performance in habitats with different salinity were estimated. In September 2020, 102 males and 102 females sourced from 17 natural reefs across the northern Gulf were bred according to 2 males x 2 females non-overlapping factorial crossing designs, resulting in 204 full and half sibs. All families were pooled after fertilization according to …

Developing A High-Efficiency Method For Field-Scale Simulation Of A Tight And Naturally Fractured Reservoir In The Williston Basin, Xincheng Wan, Lu Jin, Tao (Todd) Jiang, James A. Sorensen, Chenyu Wu, Ahmed Merzoug

EERC Publications, Papers, & Presentations

A novel FDO (fracture and DRV optimization) workflow was proposed in this study to better reproduce the production and water injection history of a tight reservoir with natural fractures in the Williston Basin. Compared to most of the published work in this area, the FDO workflow can significantly improve the simulation efficiency for field-scale simulation models considering the presence of a complex natural fracture network.

Gouldian Finch Monitoring: Nesting Activity - Goomig Project 2022 To 2023, H Winter

Irrigated Agricultural Development in the North

The Goomig Project (Weaber Plains Development Project) is an irrigated agricultural development located approximately 30 km north of Kununurra, which involved clearing approximately 9,260 ha of vegetation for agriculture. Approximately 11,470 ha of native vegetation surrounding, or remaining between, the cleared areas has been designated as a buffer area (the study area for this report) to be managed to protect surrounding conservation reserves and watercourses (Strategen 2014). Gouldian Finch monitoring in the buffer area during ongoing operations is required as a condition of project approval, and is outlined in the Gouldian Finch Conservation Plan (GFCP; Strategen 2014).

Characterization Of Boreal-Arctic Vegetation Growth Phases And Active Soil Layer Dynamics In The High-Latitudes Of North America: A Study Combining Multi-Year In Situ And Satellite-Based Observations, Michael G. Brown

Dissertations, Theses, and Capstone Projects

This dissertation examined the seasonal freeze/thaw activity in boreal-Arctic soils and vegetation physiology in Alaska, USA and Alberta, Canada, using in situ environmental measurements and passive microwave satellite observations. The boreal-Arctic high-latitudes have been experiencing ecosystem changes more rapidly in comparison to the rest of Earth due to the presently warming climatic conditions having a magnified effect over Polar Regions. Currently, the boreal-Arctic is a carbon sink; however, recent studies indicate a shift over the next century to become a carbon source. High-latitude vegetation and cold soil dynamics are influenced by climatic shifts and are largely responsible for the regions …

Can Upscaling Ground Nadir Sif To Eddy Covariance Footprint Improve The Relationship Between Sif And Gpp In Croplands?, Genghong Wu, Kaiyu Guan, Chongya Jiang, Hyungsuk Kimm, Guofang Miao, Xi Yang, Carl J. Bernacchi, Xiangmin Sun, Andrew E. Suyker, Caitlin E. Moore

School of Natural Resources: Faculty Publications

Ground solar-induced chlorophyll fluorescence (SIF) is important for the mechanistic understanding of the dynamics of vegetation gross primary production (GPP) at fine spatiotemporal scales. However, eddy covariance (EC) observations generally cover larger footprint areas than ground SIF observations (a bare fiber with nadir), and this footprint mismatch between nadir SIF and GPP could complicate the canopy SIF-GPP relationships. Here, we upscaled nadir SIF observations to EC footprint and investigated the change in SIF-GPP relationships after the upscaling in cropland. We included 13 site-years data in our study, with seven site-years corn, four siteyears soybeans, and two site-years miscanthus, all located …

Global Projections Of Flash Drought Show Increased Risk In A Warming Climate, Jordan I. Christian, Elinor R. Martin, Jeffrey B. Basara, Jason C. Furtado, Jason A. Otkin, Lauren E. L. Lowman, Eric D. Hunt, Vimal Mishra, Xiangming Xiao

School of Natural Resources: Faculty Publications

Flash drought, characterized by unusually rapid drying, can have substantial impact on many socioeconomic sectors, particularly agriculture. However, potential changes to flash drought risk in a warming climate remain unknown. In this study, projected changes in flash drought frequency and cropland risk from flash drought are quantified using global climate model simulations. We find that flash drought occurrence is expected to increase globally among all scenarios, with the sharpest increases seen in scenarios with higher radiative forcing and greater fossil fuel usage. Flash drought risk over cropland is expected to increase globally, with the largest increases projected across North America …

Reliability Analysis And Compressibility Correction Of Mercury Intrusion Porosimetry Experiments For Low-Medium-Rank Coals, Song Dangyu, Zhao Yuwei, Li Yunbo, Yu Zhen

Coal Geology & Exploration

Low-medium-rank coals are soft and exhibit significant compressibility under high pressure. Therefore, it is debatable whether the pore structure of low-medium-rank coals can be reliably determined using mercury intrusion porosimetry (MIP) experiments. In this study, MIP experiments were conducted on four samples of low-medium-rank coals. By comparing the mercury injection curves of samples with different particle sizes, as well as the macroscopic and microscopic characteristics of the samples before and after mercury injection, this study established a correction method for the mercury injection volume at the high-pressure stage and investigated the reliability of MIP experiments in determining the pore structure …

A Method For Identifying Karst Collapse Columns Based On An Improved Residual Network, Zhang Tian, Sun Lianying, Yang Yan, Tu Shuai, Wang Jinfeng

Coal Geology & Exploration

Coal mining areas have complex geological conditions, and it is critical to predict and identify karst collapse columns in these areas efficiently and accurately. Human-computer interaction is the most frequently employed to interpret karst collapse columns in traditional methods. However, with an increase in the exploration scale and the constant accumulation of generated data, the traditional manual interpretation of karst collapse columns cannot meet the demand for actual coal mining. To improve the identification accuracy of karst collapse columns, this study proposes a Collapse Column Identification Network (CINet) model, which takes the automatic recognition of karst collapse columns as binary …

Study On Factors Influencing The Self-Propelling Capacity Of Self-Propelled Water Jet Drill Bits, Liu Yong, Dai Shuo, Wei Jianping, Zhang Hongtu, Yuan Yongwang, Guo Xinhui, Gao Yingjun

Coal Geology & Exploration

The structural characteristics of inner flow field in a pipeline are the key factors influencing the self-propelling capacity and descaling-unblocking capability of the self-propelled drill bit. To address the problem concerning the effect of the changes in the inner flow field of a pipeline under the joint action of multiple jets on the self-propelling force and the resistance to water backflow, the changes of inner flow field in the pipeline under different conditions were numerically analyzed based on FLUENT, and thus the influence law of the angle of rear nozzle, the rotational speed, the annular ratio and the system pressure …
