Agenda: Innovations In Managing Western Water: New Approaches For Balancing Environmental, Social, And Economic Outcomes, University Of Colorado Boulder. Getches Wilkinson Center For Natural Resources, Energy, And The Environment

Innovations in Managing Western Water: New Approaches for Balancing Environmental, Social and Economic Outcomes (Martz Summer Conference, June 11-12)

Many aspects of western water allocation and management are the product of independent and uncoordinated actions, several occurring a century or more ago. However, in this modern era of water scarcity, it is increasingly acknowledged that more coordinated and deliberate decision-making is necessary for effectively balancing environmental, social, and economic objectives. In recent years, a variety of forums, processes, and tools have emerged to better manage the connections between regions, sectors, and publics linked by shared water systems. In this event, we explore the cutting edge efforts, the latest points of contention, and the opportunities for further progress.


Sorption Of Aqueous Fe(Ii) On Goethite Investigated With Stable Oxygen Isotopes, Pu Yue 2015 Northeastern University

Sorption Of Aqueous Fe(Ii) On Goethite Investigated With Stable Oxygen Isotopes, Pu Yue

Civil Engineering Master's Theses

This thesis work is aimed at examining the oxygen atom mixing between common iron(III) oxides and Fe(II)aq solution during the sorption process. First, 18O labeled iron(III) minerals were used in batch sorption reactors to study the exchange of oxygen atom within the Fe(II)aq - iron(III) oxide system. Results showed a much lesser extent of oxygen mixing than reported Fe mixing from previous studies, even when dissolved Fe(II) is present. The oxygen mixing extents are 3.95 % more for goethite and 9.66 % more for ferrihydrite than their respective controls within 14 days ...

A Soil Parameters Geodatabase For The Modeling Assessment Of Agricultural Conservation Practices Effects In The United States, Mauro Di Luzio, Martin L. Norfleet, Jeffrey G. Arnold, Jimmy R. Williams, James R. Kiniry

International Journal of Geospatial and Environmental Research

Soil parameters for hydrology modeling in cropland dominated areas, from the regional to local scale, are part of critical biophysical information whose deficiency may increase the uncertainty of simulated conservation effects and predicting potential. Despite this importance, soil physical and hydraulic parameters lack common, wide-coverage repositories combined to digital maps as required by various hydrology-based agricultural water quality models.

This paper describes the construction of a geoprocessing workflow and the resultant hydrology-structured soil hydraulic, physical, and chemical parameters geographic database for the entire United States, named US-SOILM-CEAP. This database is designed to store a-priori values for a suit of models ...


Better Engaging Communities: Moving Beyond Cardinal Rules, Anna G. Hoover 2015 University of Kentucky

Better Engaging Communities: Moving Beyond Cardinal Rules, Anna G. Hoover

Anna G. Hoover

“Cardinal rules” and best practice approaches have guided governmental risk communication efforts at chronic risk sites for more than two decades, playing an important role in how those most affected by contamination make sense of risk. In addition to providing information, however, communication approaches themselves can affect community perceptions indirectly, through stakeholder interpretations of the processes by which risk information is shared. It is increasingly necessary to evaluate not only whether risk communication approaches have been effective for increasing knowledge but if, in fact, the ways in which information is shared has had unintended consequences that change how stakeholders perceive ...

Pavement Underdrain To Achieve Longer Life Pavement Structure, Tommy E. Nantung 2015 Indiana Department of Transportation

Pavement Underdrain To Achieve Longer Life Pavement Structure, Tommy E. Nantung

Purdue Road School

Drainage as the key to pavement performance has been suggested since the early design of modern pavement structures. In fact, the three parameters for pavement performance are drainage, drainage and drainage. Drainage is so important to the performance of pavement that many state DOTs mandate a pavement underdrain system for routes with medium to high truck traffic. In the current evolution of pavement underdrain design, the speed of water removal from the soil foundation is the key issue. In a recent field investigation, some pavement sections with an underdrain system are not immune to pavement structural deterioration. It was determined ...

Manganese Removal By Low Cost Adsorbent From Synthetic Wastewater-A Review, Innovative Research Publications Irp India, Vinod Pahade, A. K. Sharma

Innovative Research Publications IRP India

Manganese (Mn) is one of the most abundant metals in Earth’s crust. Manganese is present in ground water as a divalent ion (Mn2+) and is considered a pollutant mainly because of its organoleptic properties. It is an essential metal for the human system and many enzymes are activated by manganese. Therefore, manganese has to be removed from some waters and wastewaters for various reasons. Conventional chemical and physical treatments for Mn(II) removal from contaminated effluent consist of precipitation, depth filtration, ion exchange, adsorption and oxidation. The adsorption technique has been found to be one of the most effective ...

Concrete Pavement Mixture Design And Analysis (Mda): Development And Evaluation Of Vibrating Kelly Ball Test (Vkelly Test) For The Workability Of Concrete, Peter Taylor, Xuhao Wang, Xin Wang 2015 Iowa State University

Concrete Pavement Mixture Design And Analysis (Mda): Development And Evaluation Of Vibrating Kelly Ball Test (Vkelly Test) For The Workability Of Concrete, Peter Taylor, Xuhao Wang, Xin Wang

InTrans Project Reports

Due to the low workability of slipform concrete mixtures, the science of rheology is not strictly applicable for such concrete. However, the concept of rheological behavior may still be considered useful. A novel workability test method (Vibrating Kelly Ball or VKelly test) that would quantitatively assess the responsiveness of a dry concrete mixture to vibration, as is desired of a mixture suitable for slipform paving, was developed and evaluated. The objectives of this test method are for it to be cost-effective, portable, and repeatable while reporting the suitability of a mixture for use in slipform paving. The work to evaluate ...


Concrete Pavement Mixture Design And Analysis (Mda): An Innovative Approach To Proportioning Concrete Mixtures, Peter Talor, Ezgi Yurdakul, Xuhao Wang, Xin Wang 2015 Iowa State University

Concrete Pavement Mixture Design And Analysis (Mda): An Innovative Approach To Proportioning Concrete Mixtures, Peter Talor, Ezgi Yurdakul, Xuhao Wang, Xin Wang

InTrans Project Reports

Mixture proportioning is routinely a matter of using a recipe based on a previously produced concrete, rather than adjusting the proportions based on the needs of the mixture and the locally available materials. As budgets grow tighter and increasing attention is being paid to sustainability metrics, greater attention is beginning to be focused on making mixtures that are more efficient in their usage of materials yet do not compromise engineering performance. Therefore, a performance-based mixture proportioning method is needed to provide the desired concrete properties for a given project specification. The proposed method should be user friendly, easy to apply ...

Assessment Of Nondestructive Testing Technologies For Quality Control/Quality Assurance Of Asphalt Mixtures, Jeramy C. Ashlock, R. Christopher Williams, Hosin David Lee, Shibin Lin, Hanjun Kim, Jeremy Nash

InTrans Project Reports

Asphalt pavements suffer various failures due to insufficient quality within their design lives. The American Association of State Highway and Transportation Officials (AASHTO) Mechanistic-Empirical Pavement Design Guide (MEPDG) has been proposed to improve pavement quality through quantitative performance prediction. Evaluation of the actual performance (quality) of pavements requires in situ nondestructive testing (NDT) techniques that can accurately measure the most critical, objective, and sensitive properties of pavement systems. The purpose of this study is to assess existing as well as promising new NDT technologies for quality control/quality assurance (QC/QA) of asphalt mixtures. Specifically, this study examined field measurements ...
