I had recently completed a book about the community acequias of the upper Río Grande and set out to compare them with counterpart systems of Valencia, Murcia, and Lorca. In Valencia the highlights included a session of the fabled Water Court, the Tribunal de las Aguas de Valencia, and a tour of huertas within the urbanized portion of city. In Murcia I visited the office of the Junta de Hacendados and from there made it a point to …

Transmountain Diversion In The Forest Wilderness: Natural History Is Human History, José A. Rivera Ph.D

Faculty Publications

The case study details how an adjudication involving the water rights of Indigenous pueblos downstream of rights held by Hispano irrigators led to a prolonged conflict not with the pueblos but between Cuba valley farmers and the United States Forest Service. It happened that an adjudication decree in federal court mandated the Nacimiento Community Ditch Association to replace its diversion located in a wilderness forest with a modern structure to partition water equitably among all users on the Jémez River. The transmountain diversion, as it was called, took water out of the Jémez basin and dropped it to a canyon …

The Zanjeras Of Ilocos In The Northern Philippines: A Legacy Of Sustainable Resource Management, José A. Rivera Ph.D

Faculty Publications

Zanjeras are farmer-managed irrigation systems that have endured for centuries in the Ilocos region of northern Luzon in the Philippines. These cooperative irrigation societies emerged during the Spanish regime when Augustinians were deployed to congregate indigenous populations into pueblos, convert them to Christianity, and raise tributes for the Crown. Zanjeras evolved from a blending of two traditions: the Iberian model of irrigation and indigenized practices of water-for-land exchanges with landowners and atar-holdings to distribute shares among the members. Like other community-based irrigation systems in Southeast Asia and globally, zanjeras are self-governed, long-enduring, and serve as exemplary models of …

Inclusive Schools Design: A Phenomenological Investigation Into Visually Impaired Lived Experiences, Sarah Oteifa, Khaled Dewidar, Yasser Mansour

Architectural Engineering

Inclusive design is an approach that aims to include special children with the general student population by developing the whole system, including the built environment, to accommodate their needs. Although efforts have been made to include children with visual impairments in the educational mainstream, available design guidelines often miss their "real lived experience". Available inclusive school design criteria are considered limited and the necessary design qualities of space to cope with their impairments are often missing the phenomenological, holistic approach. This study is conducted using a mixed method. The necessary spatial qualities are extracted from visually impaired children's real experiences …

Raveling Performance Of Conventional And Rubberized Chip Seal Under Field And Laboratory Traffic Loading, Alireza Pourhassan, Ahmed A. Gheni, Mohamed Elgawady

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Raveling, or the Loss of Surface Aggregate, is a Major Concern in Chip Seal Pavement. Previous Studies Have Used the Standard Sweep, Vialit, and Pennsylvania Tests to Evaluate Raveling, But These Tests Do Not Replicate the Stresses of Rolling Vehicle Tires on Chip Seal and Have Produced Inconsistent Results. Additionally, These Tests Mainly Evaluate Early-Stage Raveling Due to their Short Curing Time. in This Study, a Small-Wheel Traffic Simulation Device (SWTS) Was Used to Apply Similar Stresses as Rolling Vehicle Tires and Produce Comparable Raveling Results. This Was Confirmed through a 13-Month Field Observation of Chip Seal, Where the Laboratory …

Photolysis Of 3-Nitro-1,2,4-Triazol-5-One: Mechanisms And Products, Hunter W. Schroer, Esteban Londono, Xueshu Li, Hans Joachim Lehmler, William Arnold, Craig L. Just

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Insensitive munitions formulations that include 3-nitro-1,2,4-triazol-5-one (NTO) are replacing traditional explosive compounds. While these new formulations have superior safety characteristics, the compounds have greater environmental mobility, raising concern over potential contamination and cleanup of training and manufacturing facilities. Here, we examine the mechanisms and products of NTO photolysis in simulated sunlight to further inform NTO degradation in sunlit surface waters. We demonstrate that NTO produces singlet oxygen, and that dissolved oxygen increases the NTO photolysis rate in deionized water. The rate of NTO photolysis is independent of concentration and decreases slightly in the presence of Suwannee River Natural Organic Matter. …

Architecture And New Urbanism’S Relationship To Biomimicry And Floral Design, Alycia Timmerman

Honors Program: Senior Projects (Public)

The craft of floral design is classified as an art and a science. Similarly, architecture is rooted in the two disciplines. After conducting research and exploring biomimicry through the design process, it became evident that the process of design for architecture and floral design are similar. This relationship can also be extended into the field of planning and the New Urbanism movement.

Landscaping In The Utah Wildland-Urban Interface, Jordan Goff, David T. Anderson, Jake Powell, Darren Mcavoy

All Current Publications

The wildland-urban interface (WUI) is simply where human development mingles with wildland, or in other words, developed land next to undeveloped land. This area is at the highest risk for damage from wildfire. As our communities grow outward, the WUI is only expanding, putting more people at risk from wildfire. Therefore, it is important for homes built there to have fire-protective landscaping. Also, because Utah is a desert state currently in a drought, low-water landscaping is important for all Utah landscapes, including the WUI. This fact sheet addresses these issues and provides guidance on fire-protective and low-water landscaping.

Effect Of Additional Water Or Superplasticizer On Key Characteristics Of Cement Paste Made With Superabsorbent Polymer And Other Shrinkage Mitigating Materials, Kamran Aghaee, Ricarda Sposito, Karl Christian Thienel, Kamal Khayat

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The use of superabsorbent polymer (SAP) coupled with expansive agent (EA) or shrinkage-reducing admixture (SRA) can effectively reduce shrinkage of cement-based materials. However, SAP particles at high contents can adversely affect rheological and mechanical properties. Securing proper workability can be accomplished by additional water or adjusting the superplasticizer (SP) demand. There is an uncertainty about the efficiency of these approaches to workability compensation. This study evaluates the effect of additional water or SP on key properties of cement paste made with SAP and relatively high content of EA or SRA. Macro and micro mechanisms underlying the effect of combined shrinkage …
