Practical Anisotropy of Reflectance Standards
No full textFactory calibration documents for sintered PTFE and painted reflectance standards specify diffuse hemispherical reflectance at 8 degrees incidence, nadir collection. This measurement is an isotropic mean of azimuth angles. In practice, targets are measured at very specific azimuthal incidence and collection angles, requiring more rigorous BRDF knowledge if certainties of less than 2% are desired. In this presentation, a practical method for determining the azimuthal dependence of nadir collected reflectance at various incident illumination zenith angles is described and discussed

Hydraulic Measurements in a SAF Stilling Basin With a Stepped Chute for Embankment Protection
No full textStepped chutes have become commonplace in embankment dam rehabilitation projects due to project economy, constructability, and improved chute energy dissipation. Consequently, for applications where a stilling basin is merited the interaction of stepped chutes and stilling basins is of high interest. A commonly used stilling basin type for many smaller embankment dams, the St. Anthony Falls stilling basin (SAF), has no specific hydraulic design guidance for use downstream of a stepped chute. Therefore, this study was conducted at the Utah Water Research Laboratory in a flume with 0.1 m tall steps, a total drop height of 1.8 m, and an embankment slope of 3H:1V, with flow terminating in a SAF basin designed for a Froude number of 4.0. Basin performance for laboratory unit discharges from 0.32 to 0.69 m2/s and incoming Froude numbers from 3.7 to 4.0 were evaluated. Key observations included water surface profiling, basin sensitivity to downstream tailwater, and hydrodynamic pressures acting on the basin floor and baffle blocks, including pressure fluctuations. This work aims to provide additional insights and guidance to engineers when selecting a stepped overtopping protection scheme coupled with a hydraulic jump stilling basin
Enhancing Embankment Dam and Levee Resilience Against Overtopping Erosion: The Muscatine Island Levee Project
No full textHydroTurf® is an advanced revetment solution engineered to protect embankment dams and riverine levees from erosion caused by overtopping events. Its design provides an impermeable geomembrane protected by engineered turf with a high strength cementitious infill, resulting in a fiber reinforced high-strength concrete matrix. The system provides a durable and impermeable barrier against erosive forces.
The Muscatine Island Levee Improvement Project, situated along the Mississippi River in Iowa, exemplifies the application of HydroTurf. This initiative aimed to enhance flood protection for approximately 30,000 acres of commercial, industrial, and residential areas. A critical component was the construction of a hardened controlled overtopping structure at the downstream end of the levee. HydroTurf was selected for this 1,000-foot section to ensure resilience against potential overtopping scenarios. Its robust design offers superior erosion resistance, thereby maintaining the levee\u27s structural integrity during high-flow events.
The decision to implement HydroTurf was driven by the imperative to protect lives and property from flood-related damages. Traditional methods, such as riprap or concrete armoring, often present challenges related to cost, installation complexity, and long-term maintenance. In contrast, HydroTurf provides a cost-effective and efficient alternative, with reduced maintenance requirements and enhanced durability.
This paper explores the design elements of the Muscatine Island Levee Project and material selection criteria that informed the final solution. Ultimately, this project underscores HydroTurf’s effectiveness and potential for broader application in flood risk management strategies

\u3cem\u3eJust\u3c/em\u3e Distribution of Tree Canopy? A Digital Approach to Tree Equity
No full textTrees in U.S. cities are unevenly and inequitably distributed. To address this challenge, planners increasingly use digital tools to prioritize areas and communities for tree projects. The goal is to achieve tree equity wherein all populations have access to the benefits of urban trees. Here we identify limitations and opportunities in the operationalization of the tree equity concept via digital platforms. We call on planners using digital tools in urban forest planning to (1) incorporate data that capture the heterogeneity of spaces in which urban trees grow, (2) include and support marginalized communities in urban forest planning, and (3) couple digital tools with local community engagement across the life-span of tree-related projects
