“…Las medias de las temperaturas máximas resultaron menores en la estación PC que sobre la estación más alta del valle. Estudios anteriores también evidenciaron un efecto refrescante de áreas litorales (Murakawa et al, 1991;Giampietri y Piccolo, 2000;Anderson et al, 2007;Rykken et al, 2007;Huang et al, 2008;Hathway y Sharples, 2012;Tsai et al, 2017;Wang et al, 2022). No obstante, otros autores como Brooks y Kyker-Snowman (2009), Giannakis et al (2016) y Vásquez (2016 no hallaron diferencias significativas entre las temperaturas de sitios ribereños y no ribereños.…”

“…La mayoría de los estudios se han centrado en el análisis de la regulación climática en verano. Sin embargo, autores que han examinado el papel de cuerpos y cursos de agua en escalas temporales mayores evidenciaron que dicho efecto enfriador ocurre en todas las estaciones del año (Giampetri y Piccolo, 2000; Tsai et al, 2017). Lo anterior coincide con lo observado en la ciudad de Neuquén.…”

“…Las Tmin medias mostraron valores mayores en la estación PC que en NA, con diferencias mayores en invierno y otoño. Lo mismo observaron en sus trabajos Giampetri y Piccolo (2000) y Tsai et al (2017). También autores como Hathway y Sharples (2012) y Wang et al (2022), quienes evaluaron el efecto regulador del agua con resolución horaria, observaron que la regulación térmica era mucho más débil durante la noche que durante el día.…”

This paper aimed to compare the behavior of climatic elements and extreme thermal events between two landscape units of the city of Neuquén, Argentina, for the period 2013-2020. The study involved daily data of minimum temperature (Tmin), maximum temperature (Tmax), and relative humidity (RH) obtained from the meteorological stations "Neuquén Aero" (NA) and "Paseo de la Costa" (PC), referring to the valley (peri-urban area) and the fluvial corridor (riparian environment) respectively. The influence of the riverbank on the daily Tmin and Tmax during Heat Waves (HW) and Cold Waves (CW) in the valley was analyzed using the methodology of the National Meteorological Service. The mean Tmax (Tmin), at annual, seasonal, and monthly resolutions, were lower (higher) in PC. The mean RH values were higher in NA. During the HW, a regulatory effect was exhibited regarding the number of days that the threshold values were exceeded consecutively in the fluvial littoral.

“…In addition to having excellent cooling capacity, they allow for the spread of cold air through evaporation and suitable heat transfer (Aram et al 2019), thus affecting the microclimate of the urban riverfro nt area and reducing the temperatu re of surrounding areas (Kim et al 2008). The urban river cooling effect (RCE) has led to riverfront spaces being cooler than inner city spaces, and could effectively moderate extreme temperatu re changes in cities (Tsai et al 2017).…”

River blue-green spaces are an important type of urban cooling island, and their cooling effect is largely influenced by the spatial pattern of urban riverfront areas. These areas are the primary source of the urban heat island effect in high-density areas along urban rivers. However, the sensitivity of spatial pattern variables to the river cooling effect is not well understood. To address this question, the Grand Canal in the main city of Hangzhou, was selected as study area. This study identified three building space form variables and seven green space form variables based on area, spatial pattern, and correlated these indicators with land surface temperature using the Autogluon model, then calculated the river cooling effect from the land surface temperature, and tested the sensitivity of these spatial pattern indicators by comparing their effects on the river cooling effect. The results are that: (1) the Autogluon model accurately establishes the relationship between land surface temperature and spatial pattern indicators; (2) the river cooling index (RCI) of the Grand Canal in the main city of Hangzhou ranges from 0.67-5.35℃, with an average RCI of 2.62℃, and the river cooling distance (RCD) ranges from 25.6-370.4m, with an average RCD of 167.3m; (3) Building patch density, Overall greenspace patch cohesion index, and greenspace patch density exhibits high sensitivity to regulating the river cooling effect(RCE). This study provides valuable references for identifying key spatial pattern regulating indicators in urban riverfront spatial planning, and for enhancing the cooling effect of medium-sized urban cooling islands and optimizing the outdoor thermal comfort of areas along rivers through rapid simulation evaluation methods.

“…This enacted law is an excellent opportunity that aids in preserving the green space in an urban area. Although this beneficial urban green space has been only emphasized for riverbank stabilization, bio-diversity, and water quality purposes [1,2], prior studies have verified that vegetated riparian reduces outdoor thermal condition when compared to impervious surface areas [3,4]. Vegetation has been proven to be an effective way to minimise urban temperatures [5] and the low evapotranspiration rate from the soil-vegetation system in urban areas is one of the major drivers that increase daytime temperatures [6].…”

The cooling effect potential of urban river reserve in Johor, Malaysia

2018

The Malaysian riparian buffer strip is also called the river reserve. As the state authority has the right to reserve state land for public purposes, there is high prospect to preserve green space in urban areas. Urban riparian, however, has been used only for bank stabilization, biodiversity, and water quality purposes. Prior studies verified that vegetated riparian minimises outdoor thermal condition, in comparison to impervious surface areas. Strategic distribution of green space and cooling sources in city planning are vital for maximum efficiency of green strategies. Hence, this paper determined the cooling effect potential of urban riparian structure on local thermal environment by investigating three river reserve areas. Thermal measurements were recorded at six locations perpendicular to the riverbank at 20m intervals, along with a census of vegetation formation. Although the riparian zoning was located along the same river, different widths and various vegetation formations affected thermal distribution. The ΔTi outcomes indicated that despite the small and restricted green space allocated in urban areas, the cooling effect was still present. Hence, green strategies must be carefully crafted to maximize use of space. The effects of urban riparian structure generate the multi-functions of urban river reserve, especially its cooling effect.
