Investigation on Airport Landscape Cooling Associated with Irrigation: A Case Study of Adelaide Airport, Australia

Abstract

Extreme summertime heat is becoming a major issue for aircraft operations. As global temperatures continue to rise, some of the heaviest planes on the longest flights may eventually be unable to depart during the hottest part of summer days. During summer days, some airports have to reduce the payload of aircraft, including cargo and/or passengers in the hotter days of summer. Nonetheless, there is no existing body of research on the potential for airport cooling. Furthermore, extreme heat on the ground also affects airport workers; loading and unloading luggage and servicing platforms between flights could become more arduous. With global warming proceeding, it is becoming increasingly urgent to find a suitable strategy to cool airport environments, perhaps by irrigation of a vegetated landscape. All airports have large enclosed areas (usually of grass) acting as a buffer between airport activities and the adjacent industrial, commercial and residential land utilization. This paper describes the trial of irrigating the buffer area of Adelaide airport and analyzes the performance of irrigation cooling for Adelaide airport, examining whether this can benefit human thermal comfort. Results indicate that irrigation provides cooling, and the cooling effect reduces along with the increasing instance from the middle of the irrigation area. At 15:00, the average air temperature was 1.8 °C cooler in the middle of the irrigation area than in the non-irrigation area, and the relative humidity was 5.8% higher during the trial period. On an extremely hot day (the maximum air temperature was 45.4 °C), it was 1.5 °C cooler in the middle of the irrigation area than upwind the of irrigation area, and 0.8 °C cooler than downwind of the irrigation area at 13:00. Human thermal comfort (HTC) is unfavorable in the runway, but greater improvements can be made through promotion of irrigation.

Exploring the link between Atmospheric conditions and Acid rain prevalence: a 12-year study at Juanda International Airport, Sidoarjo, Indonesia.

“…The selected measuring station for this study is located three meters above sea level, providing a representative sampling location to ensure the accuracy of the recorded data [5]. The study adopted a systematic approach, focusing on the collection and analysis of rainwater quality, temperature, and humidity data within the Juanda International Airport area [9]. The time frame for the data collection spanned twelve years, from 2010 to 2021.…”

“…Acid rain poses significant environmental and health concerns, affecting everything from human health to the structural integrity of built environments and the mechanical properties of materials such as asphalt [2], [7][8][9]. The Juanda International Airport, approximately 20 km from Surabaya City and 3 km west of the Madura Strait waters, has a geographical location that influences local rain formation.…”

Impact of Environmental Factors and System Structure on Bioretention Evaporation Efficiency

“…Bioretention is an effective low impact development (LID) technology for stormwater management of first-flush rainwater treatment in small scale catchments, which is a potential method for processing water quality and managing water quantity [1,2]. Bioretention is a soil-vegetation system, also known as rain garden, controlling water quantity by filtration and evaporation, and removing pollutants through filtration, adsorption, microbe exchange, and other functions in the soil [3][4][5][6]. The LID technology is widely used for urban stormwater management and flood protection [7,8].…”
