Air Pollution in Two Districts of the City of Cusco: An Interdisciplinary Study Based on Environmental Monitoring and Social Risk Perception

Enma Tereza Huaman Chulluncuy, Eliana Magda Ibarra Cabrera, Daniel Mendoza, Fredy S. Monge et autres

Air pollution is a growing environmental and public health concern, particularly in urban areas where vehicular emissions, industrial activities, and public events contribute to deteriorating air quality. This study examines air pollution concentrations in two districts of Cusco, Peru, using an interdisciplinary …

A Numerical Investigation of the Relationship Between Air Quality, Topography, and Building Height in Populated Hills

Marian Montalvo, Daniel Horna

Urban population growth has led to increased air pollution, influenced by disrupted wind patterns and the heterogeneous distribution of pollutants. Although the relationship between urban form and air quality is well recognized, it is often examined in isolation and through simplified urban …

Study of the influence of surface roughness and topography on wind profiles and the dispersion of atmospheric pollutant in two populated hills in Cusco, Peru

Rebeca Mallqui, Daniel Horna

The urban areas of many developing cities are suffering from environmental problems due to overpopulation and inadequate public services, in that sense, air pollution is one of the biggest problems. In general, Latin American cities have a higher density of vehicles and …

Assessment of Present and Future Water Security under Anthropogenic and Climate Changes Using WEAP Model in the Vilcanota-Urubamba Catchment, Cusco, Perú

Andrés Goyburo, Pedro Rau, Waldo Lavado‐Casimiro, Wouter Buytaert et autres

Water is an essential resource for social and economic development. The availability of this resource is constantly threatened by the rapid increase in its demand. This research assesses current (2010–2016), short- (2017–2040), middle- (2041–2070), and long-term (2071–2099) levels of water security considering …

Air Quality Analysis in Lima, Peru Using the NO2 Levels during the COVID-19 Pandemic Lockdown

Diego Velayarce, Qespisisa Bustos, María Paz García, Camila Timana‐Mendoza et autres

The emergence of the new COVID-19 virus in Peru forced the Peruvian government to take swift measures to stop its proliferation. Consequently, a state of emergency was declared, which included mandatory social isolation and quarantine. This action meant that people would transit …

Horizontal transport under wind-induced resonance in stratified waterbodies

Hugo N. Ulloa, George Constantinescu, Kyoungsik Chang, Daniel Horna et autres

Wind is the primary driver of horizontal flows in stratified lakes. Its periodic nature may cause a resonance regime when its frequency matches that of an internal mode of motion of the waterbody forced by it. Here, we show via numerical experiments …

Density Effects at a Concordant Bed Natural River Confluence

Daniel Horna, George Constantinescu, Bruce L. Rhoads, Quinn W. Lewis et autres

Abstract Confluences are locations of complex hydrodynamic conditions within river systems. The effects on hydrodynamics and mixing of temperature‐induced density differences between incoming flows are investigated at a small‐size, concordant bed confluence. To evaluate density effects, results of eddy‐resolving simulations for a …
