“…However, in urban areas the heterogeneity of soils is a major issue in using such maps. Soils in urban areas can vary significantly from soils with the same classification in natural non urban areas due to; (1) the degree of compaction over time due to construction and heavy loads; (2) the amount of organic matter; and, (3) contamination from construction debris and unspecified construction fill [2][3][4][5]. This makes it challenging to classify urban soils in the normal soil taxonomy groups, and assume water infiltration properties that are based on values given in tables.…”

Coupling Field Observations and Geographical Information System (GIS)-Based Analysis for Improved Sustainable Urban Drainage Systems (SUDS) Performance

Urbanization and increased precipitation volumes and intensities due to climate change add pressure to the urban drainage system, resulting in increased flooding frequencies of urban areas and deteriorating water quality in receiving waters. Infiltration practices and the use of blue green infrastructure, also called Sustainable Urban Drainage Systems (SUDS), can limit, and, in some cases, reverse the effects of urbanization. However, adequate infiltration capacity is an essential parameter for the successful implementation. In this paper, a Geographical Information System (GIS)-based hydrology analysis for SUDS placements is coupled with field measurements using Modified Phillip Dunne infiltrometer tests. The case study area is the expansion of the campus at the Norwegian University of Science and Technology (NTNU) over the next decade. Infiltration in urban soils can be highly heterogenous over short distances. When comparing measured infiltration rates with physical characteristics of the soils showed that the physical characteristics are not a good indication of the infiltration potential in urban soils with a large degree of compaction. The results showed that measuring the infiltration potential combined with flow path analysis can greatly enhance the benefits of blue green infrastructure, with an up to 70% difference in area required for SUDS solutions for managing 90% of the annual precipitation.

“…Mathissen et al 72 , Sanders et al 60 and Kumar et al 59 reported that TWP and BWP can be even emitted as ultrafine particles due to a thermomechanical process that causes evaporation and re-condensation. A bimodal size distribution for TWP has been suggested with one maximum in the fine mode and another in the coarse mode [73][74][75][76] . On the contrary, an unimodal size distribution has been reported for BWP with maxima ranging between 1.0 and 6.0 μm 21,28,36,60,77 (Extended Data Fig.…”

In recent years, marine, freshwater and terrestrial pollution with microplastics has been discussed extensively, whereas atmospheric microplastic transport has been largely overlooked. Here, we present the first global simulation of atmospheric transport of microplastic particles produced by road traffic (TWPs – tire wear particles and BWPs – brake wear particles), a major source that can be quantified relatively well. We find a high transport efficiency of these particles to remote regions, such as the Arctic Ocean (14%). About 34% of the emitted coarse TWPs and 30% of the emitted coarse BWPs (100 kt yr-1 and 40 kt yr-1 respectively) were deposited in the World Ocean. These amounts are of similar magnitude as the total estimated terrestrial and riverine transport of TWPs and fibres to the ocean (64 kt yr-1). Atmospheric transport of microplastics is thus an underestimated threat to global terrestrial and marine ecosystems and affects air quality on a global scale, especially considering that other large but highly uncertain emissions of microplastics to the atmosphere exist. High latitudes and the Arctic are highlighted as an important receptor of mid-latitude emissions of road microplastics, which may imply a future climatic risk, considering their affinity to absorb solar radiation and accelerate melting.

“…In addition to fine sediment, various other pollutants from road run-off can affect stream ecosystems negatively (Brown, 1994;Gilson, Malivia, & Chareneau, 1994;Lamont & Blyth, 1995;Yousef, Wanielista, Harper, & Skene, 1983;Yousef, Wanielista, & Harper, 1985). Depending on the location, rural versus urban, as well as the land use (e.g., agriculture and mining), road run-off may include a range of pollutants such as fertilizers, pesticides, herbicides, solutes, heavy metals, plastics, polycyclic aromatic hydrocarbons, mineral oil hydrocarbons, pharmaceutical contaminants, and soluble salts (Froehner et al, 2012;Göbel, Dierkes, & Coldewey, 2007;Hussain, Rahman, Prakash, & Hoque, 2015;Wang, Zhang, Wu, & Wang, 2017) Many studies investigating road run-off in temperate areas have focused on de-icing salts and heavy metals.

Ecohydrological disturbances associated with roads: Current knowledge, research needs, and management concerns with reference to the tropics

et al. 2017

Roads are a pervasive form of disturbance with potential to negatively affect ecohydrological processes. Some of the most rapid growth in road networks is occurring in developing countries, particularly in the tropics, where political agendas are often focused on strengthening the economy, improving infrastructure, bolstering national security, achieving self‐sufficiency, and increasing citizen well‐being, often at the expense of the environment. We review what is known about road impacts on ecohydrological processes, focusing on aquatic systems, both temperate and tropical. We present seven cases that represent the broader trends of road development and impacts in tropical settings. Many of these process dynamics and impacts are not different from those experienced in temperate settings, although the magnitude of impacts in the tropics may be amplified with intense rainfall and lack of best management practices applied to road construction/maintenance. Impacts of roads in tropical settings may also be unique because of particular organisms or ecosystems affected. We outline a set of best practices to improve road network management and provide recommendations for adopting an agenda of research and road management in tropical settings. Importantly, we call for incorporation of transdisciplinary approaches to further study the effects of roads on ecohydrological processes in the tropics. Specific emphasis should also be placed on collaboration with governments and developers that are championing road development to help identify the drivers of road expansion and thresholds of negative impact, as well as methods of sustainable road construction and maintenance.
