The Life Cycle of the South American Monsoon System
Publisher: American Meteorological Society
Abstract: The South American monsoon system (SAMS) life cycle plays an important role in the distribution and duration of the rainy season mainly over southwestern Amazonia, and the central west and southeast Brazil regions, affecting ...
Mineral Waste Geopolymeric Artificial Aggregates as Alternative Materials for Wastewater-Treatment Processes: Study of Structural Stability and pH Variation in Water
Publisher: American Society of Civil Engineers
Abstract: Artificial aggregates produced from mine waste geopolymeric binders were studied as a potential substrate for fixed-film wastewater-treatment processes (biofilm reactors). Waste geopolymeric artificial aggregates (WGA) of ...
Atmospheric Circulation Features Associated with Rainfall Variability over Southern Northeast Brazil
Publisher: American Meteorological Society
Abstract: The atmospheric circulation features associated with rainfall variability during the main rainy period of the region of southern Northeast Brazil (sNEB) are determined through principal components analysis and cluster ...
Optimal Nonlinear Predictive Control for Canal Operations
Publisher: American Society of Civil Engineers
Abstract: The predictive canal operation method (PCOM) provides optimal real-time control of irrigation canals with incorporation of current and forecasted demands. PCOM utilizes an efficient, nonlinear, optimal control algorithm ...
Simulations of the Hydrological Cycle over Southern South America Using the CPTEC/COLA AGCM
Publisher: American Meteorological Society
Abstract: The La Plata River basin is the second largest basin of South America after the Amazon basin, and it is located in an international area that occupies territories of Argentina, Uruguay, Brazil, Paraguay, and Bolivia, areas ...
Influence of Execution Speed on Displacements of Soil-Nailed Structures with Vertical Face in Urban Areas
Publisher: ASCE
Abstract: This paper presents the study of the execution speed influence on displacements of soil-nailed structures with a vertical face in urban areas, intended as the basements of buildings. Fifteen structures in the Metropolitan ...
Vertical-Facing Loads in Steel-Reinforced Soil Walls
Publisher: American Society of Civil Engineers
Abstract: The paper investigates the influence of backfill soil, foundation soil, and horizontal joint vertical compressibility on the magnitude of vertical loads developed in steel-reinforced soil concrete panel retaining walls at ...
Evaluating the Cost-Effectiveness of Roadside Culvert Treatments
Publisher: American Society of Civil Engineers
Abstract: Roadside cross-drainage culverts have been found to affect vehicle accident injury levels. As a result, highway designers have commonly used three safety treatments to protect errant motorists from striking culvert openings. ...
Geotechnical Aspects of Eroded Sediments Relevant to Tailings Disposal Design
Publisher: American Society of Civil Engineers
Abstract: Since 1975, Samarco Mineração S.A. has been mining the iron ore deposits of the Germano Mine in the Quadrilátero Ferr
Behavior of Laterally Top-Loaded Deep Foundations in Highly Porous and Collapsible Soil
Publisher: American Society of Civil Engineers
Abstract: Problems associated with horizontal loading in foundation structures often occur when the surface soil has particular characteristics like the unsaturated, porous, and collapsible soils that are very common in Brazil. In ...
