Are urban waterways amenities, and if so, are there inequities in household access? While represent a potential site for access to nature within the environment, have been few studies on accessibility interactions with water features particular, what we refer as "blue spaces." This study drew sample of households Northern Utah living neighborhoods nearby river or canal ask local provide positive impacts proximity them increased likelihood spending time at being familiar them. We used...
Abstract Urban areas are responsible for a substantial proportion of anthropogenic carbon emissions around the world. As global populations increasingly reside in cities, role urban determining future trajectory is magnified. Consequently, number research efforts have been started United States and beyond, focusing on observing atmospheric dioxide (CO 2 ) relating its variations to cities. Because intimately tied socioeconomic activity through combustion fossil fuels, many cities actively...
Abstract Urbanization, climate, and ecosystem change represent major challenges for managing water resources. Although systems are complex, a need exists generalized representation of these to identify important components linkages guide scientific inquiry aid management. We developed an integrated Structure‐Actor‐Water framework ( iSAW ) facilitate the understanding transitions sustainable systems. Our goal was produce interdisciplinary resources research that could address management...
In this paper we examine whether land-cover measures derived from multi-spectral (MS) imagery in combination with light detection and ranging (LiDAR) data sources better predict parcel scale urban water consumption than solely MS imagery. Land-cover such as the percentage of impervious surface vegetative cover are important predictors household level use. This study found that additional effort required to obtain LiDAR does not appear add predictive power for demand modeling. We suggest is...
The Utah Transit Authority (UTA) serves Utah's Wasatch Front, a rapidly growing conurbation with current population of ∼1.8 M people. UTA uses an electronic fare collection (EFC) system that requires riders to tap on as they enter bus or train and off exit, well automated passenger counter (APC) counts interruptions infrared beams across vehicle doorways board alight. We analyzed EFC APC data for 2016, along service schedules routes from General Feed Specification (GTFS) data, estimate the...
This study reports economic development outcomes—defined as change in employment—for areas within 0.25 mi of three streetcar stations along four lines each cities: Portland OR; Salt Lake City UT; Seattle WA; and New Orleans LA. Employment 3 years prior to the start construction was compared with employment station 2013. Before–after comparisons were also applied 10 bus stops urbanized area selected "controls" because they quantitatively comparable studied. Shift-share analysis is used...
Abstract This study investigates the impact of climate and land use change on magnitude timing streamflow sediment yield in a snow‐dominated mountainous watershed Salt Lake County, Utah using scenario approach Hydrological Simulation Program — FORTRAN model for 2040s (year 2035–2044) 2090s 2085–2094). The scenarios were statistically dynamically downscaled from global models. Land cover (LULC) changes estimated two ways regional planning deterministic model. Results indicate mean daily...
Abstract Riparian forests are essential for stream ecological processes in arid and semiarid regions, however, they often highly altered by the rapid expansion of urban areas. To maintain riparian ecosystems services, it is important to better understand effects urbanization on forests. We quantified three‐dimensional (3D) structure woody species composition a corridor Utah, USA, evaluate patterns vegetation along reaches that flow through distinct hydrologic domains (with gaining losing...
Transportation systems are central to all cities, and city planners policy makers take special interest in assuring these efficient, functional, sustainable, and, increasingly, that they have a positive impact on human health. In addition, vehicular emissions increasingly costly cities due congestion its public This study aims show the associations between media environmental variables associated transit ridership. By tracking influence, we illustrated how coverage attention an issue over...
Abstract Riparian corridors are critical refuges for biodiversity in arid regions like the southwestern US. Birds particular rely on these habitats breeding and as migratory stopover sites within a resource‐scarce landscape. Climate change is likely to affect distribution of resources across such landscapes how birds use riparian zones. In this study, we used 15 years bird‐banding data (1994–2008) from eight state Utah examine effects variation climate vegetation at community population...
