Fees and governance: Towards sustainability in water resources management at schools in post-apartheid South Africa

Goonetilleke, Ashantha (Elsevier, 2019-11)

Water scarcity is increasingly staking a claim next to energy as a threat to the sustainability of large cities, especially in developing countries with limited resources. The recent crisis brought on by Cape Town’s “Day ...
Behaviour of metals in an urban river and the pollution of estuarine environment

Goonetilleke, Ashantha (Elsevier, 2019-11)

The high pollutant loads discharged from cities pose risks to urban waterways, and in turn the estuarine environments, making it challenging to improve urban liveability. Past studies on the behaviour of pollutants in ...
Nitrate-dependent Uranium mobilisation in groundwater

Goonetilleke, Ashantha (Elsevier, 2019-11)

Nitrate is a critical substance that determines the prevailing redox conditions in groundwater, and in turn the behaviour of Uranium (U). Therefore, the excessive use of nitrate-fertiliser in agricultural catchments could ...
Influence of physicochemical properties of road dust on the build-up of hydrocarbons

Goonetilleke, Ashantha (Elsevier, 2019-12)

Understanding the factors influencing the build-up behaviour of different pollutants accumulated on urban roads is essential for the implementation of effective stormwater pollution mitigation strategies. Even though a ...
Taxonomy of influential factors for predicting pollutant first flush in urban stormwater runoff

Goonetilleke, Ashantha (Elsevier, 2019-12)

Pollutant first flush in urban stormwater runoff is an important phenomenon influenced by a range of rainfall and catchment related variables. Even though numerous studies have been undertaken to mathematically define the ...
Quality Assessment of stormwater through different sources of a sub-tropical town of India

Goonetilleke, Ashantha (American Geophysical Union, 2019-12)

In the last few decades, the world has witnessed rapid urbanization. One of the many complex problems which have come up with increased urbanization is that of rapid drainage of storm water from the inhabited areas. Roorkee, ...
Assessment of human health risks from metals in urban stormwater based on geochemical fractionation and bioavailability

Goonetilleke, Ashantha (Springer, 2019-12)

Risks posed by metals in stormwater is directly influenced by their geochemical fractionation and, in turn, the bioavailability. Therefore, accurate quantification of the risks from metals should be undertaken by considering ...
Metals in the urban stormwater environment

Goonetilleke, Ashantha (Springer, 2019-12)

Stormwater reuse is one of the viable alternatives to overcome the growing water demand in urban areas. However, effective use of stormwater as an alternative water resource is constrained due to the presence of toxic ...
Research design for investigating metal transformations on urban roads

Goonetilleke, Ashantha (Springer, 2019-12)

Investigations into the transformation characteristics of metals deposited on urban roads required a scientifically robust research design. Sample collection and laboratory analyses were two important steps in the overall ...
Metal transformation and stormwater quality

Goonetilleke, Ashantha (Springer, 2019-12)

A detailed understanding of the metal transformation processes and consequent stormwater quality impacts provides a platform for the implementation of effective stormwater pollution mitigation strategies. This chapter ...
Practical implications and recommendation for future research

Goonetilleke, Ashantha (Springer, 2019-12)

This chapter summarises the key outcomes of the research study undertaken to investigate metal transformations on urban road surfaces and their potential impacts on stormwater quality. In particular, it discusses the ...
Creating a hierarchy of hazard control for urban stormwater management

Goonetilleke, Ashantha (Elsiever, 2019-12)

Urban stormwater reuse is becoming increasingly prevalent to overcome the serious urban water scarcity being experienced around the world. Therefore, the adoption of reliable approaches to minimise the human health risk ...
Determining disaster severity through social media analysis: testing the methodology with South East Queensland Flood tweets

Goonetilleke, Ashantha (Elsevier, 2020-01)

Social media was underutilised in disaster management practices, as it was not seen as a real-time ground level information harvesting tool during a disaster. In recent years, with the increasing popularity and use of ...
The prediction of flood damage in coastal urban areas

Goonetilleke, Ashantha (IOP, 2020)

The increase of impervious surfaces in the urban area triggers a flood. A flood occurs area with a dense population that will result in a lot of damage. The flood simulation itself is not adequate to calculate the flood ...
Transformation processes of metals in urban road dust

Goonetilleke, Ashantha (Springer, 2020)

This book discusses the physicochemical changes (transformations) that metals deposited on urban road surfaces undergo during dry weather periods, in order to provide insights into their potential impacts on stormwater ...
Abundance, distribution patterns, and identification of microplastics in Brisbane River sediments, Australia

Goonetilleke, Ashantha (Elsevier, 2020-01)

Plastic pollutants in aquatic ecosystems have received wide attention and research endeavours since early 1970s. However, in comparison to marine environments, the occurrence of microplastics in a tidal river system remains ...
Transformation and degradation of polycyclic aromatic hydrocarbons (PAHs) in urban road surfaces: Influential factors, implications and recommendations

Goonetilleke, Ashantha (Elsevier, 2020-02)

Polycyclic aromatic hydrocarbons (PAHs) are prone to post-emission transformation and degradation to yield transformed PAH products (TPPs) that are potentially more hazardous than parent PAHs. This review provides a ...
Dataset for the quantitative structure-activity relationship (QSAR) modeling of the toxicity equivalency factors (TEFs) of PAHs and transformed PAH products

Goonetilleke, Ashantha (Elsevier, 2020-02)

Sixteen significant physicochemical predictor variables for thirty PAHs and transformed PAH products (TPPs) were retrieved individually prior to collation from ChemSpider.com [1] whilst their corresponding toxicity equivalency ...
Surrogate measures to assess mobility of people as a resilience indicator in disaster management: an exploratory study in southeastern Sri Lanka

Goonetilleke, Ashantha (Springer, 2020-02)

Understanding social resilience can assist in the formulation of disaster management policies to help communities better prepare for, respond to, and recover from disasters. However, direct social resilience measurement ...
Application of quantitative structure-activity relationship (QSAR) model in comprehensive human health risk assessment of PAHs, and alkyl-, nitro-, carbonyl-, and hydroxyl-PAHs laden in urban road dust

Goonetilleke, Ashantha (Elsevier, 2020-02)

The carcinogenic human health risks (CHHR) posed by the exposure to PAHs and transformed PAH products (TPPs) are currently inconclusive due to the lack of toxicity equivalency factors (TEFs) for most TPPs although some of ...
