“…During flood events, water treatment facilities can become inundated, contaminating both overland and subsurface water (Coffey et al 2014;Boholm & Prutzer 2017;Parkinson et al 2021). Drought events particularly impact groundwater by concentrating contaminants and degrading the water quality (Tung et al 2012;Coffey et al 2014;Ekstrom et al 2017).…”

Climate change will impact water bodies and create significant challenges for natural resource managers. Despite the increasing impacts of climate change on water quality, the development and implementation of long-term strategic adaptation measures are seldom governmental priorities. So far, research has mainly tended to focus on the availability and volume of water rather than the quality. Comparatively fewer studies have considered adaptation strategies that deal with the uncertainties of the impacts of climate change on the quality of water bodies. This paper reports the results of a systematic review of literature on adaptation options and the barriers and drivers that can exert a positive or negative influence on their implementation. Findings suggest that there has been and continues to be a cautious approach to a growing concern for a natural resource of utmost necessity. Most of the strategies mentioned in the literature use coping or incremental approaches. However, adaptation strategies offering low levels of resilience for addressing water quality may not be up to the challenge of significant future climate changes.

“…Many studies combined GCMs and hydrological models to assess water resource, streamflow, or ecosystem effects on catchment scales (Li et al 2009;Tung et al 2012;Chiang et al 2013;Niraula et al 2013). The GWLF, a physic-based model, was chosen as the hydrological model for assessing streamflow impacts in this study.…”

“…Climate change has different impacts on river discharge worldwide (Thodsen 2007;Sato et al 2012;Hong et al 2014). Previous studies that used scenarios from the Third Assessment Report (TAR) of the Intergovernmental Panel on Climate Change (IPCC) indicated that streamflow in Taiwan will decline during the dry season and increase during the wet season (Tung 2001;Yu et al 2002;Li et al 2009;Tung et al 2012). Taiwan's water demand has grown under global climate change and rapid social and economic development.…”

“…The Generalized Watershed Loading Function (GWLF), a lumped conceptual water balance model, is a physical process model (Evans et al 2002). Moreover, the GWLF has been used worldwide for assessing changes in streamflow (Chang 2003;Wu et al 2007;Tung et al 2012;Chiang et al 2013) and for assessing climate change impacts (Li et al 2009;Schneiderman et al 2010).…”

This study investigated the streamflow impacts in wet and dry spells using a statistical downscaling projection method to obtain 5 km girds under four Representative Concentration Pathway (RCP) scenarios. Two upstream catchments, the Dahan and Laonong Rivers were selected as the study areas. A water balance hydrological model, also known as the Generalized Watershed Loading Function model, was used to simulate the streamflow impacts. There are 126 projections from 41 general circulation models (GCMs) and 4 RCPs used in this analysis. The analytical results indicate that the streamflow impacts in different RCP scenarios are significant but vary with individual GCM's projection. The variance of 20 selected GCMs is close to that of all other GCMs. Typically, more than 60% of GCMs project that in the early 21 st century, streamflow in each RCP increases by 0 -40% in wet spells and decrease by -40 ~ 0% for the Dahan River, but the streamflow increases during both wet and dry spells for the Laonong River. In the late 21 st century, the streamflow decreases by 60% during dry spells in the Laonong River. Various predictions for the early and late 21 st century show high variance of streamflow impacts. As such, decision makers must plan for reservoir operation and flexible water deployment adaptations during future dry spells.

Sustainability has recently been acknowledged as a crucial issue in infrastructure projects. Developing a model to evaluate project sustainability according to sustainability indicators plays a major role in promoting the sustainable development of water environment treatment public-private partnership (PPP) projects. Traditional sustainability assessments are mostly based on the triple bottom line (economic, social, and environmental) and lack a more integrated indicator system. To connect the research gap, this paper identifies 27 factors that affect the sustainability of water environment treatment PPP projects from five dimensions: economy, society, resources and environment, engineering, and project management using exploratory factor analysis. The fitting degree between the model and original data is verified by confirmatory factor analysis. The results showed that the fitting was successful. This paper makes two contributions: first, it provides a comprehensive sustainability evaluation indicator system from five aspects, laying a foundation for the evaluation of project sustainability. Second, this study defines a methodology to evaluate and rank factors, identifies the indicators that show the most significant impact on project sustainability in the five dimensions, which provide a reliable reference for the public and private sector to take appropriate measures to improve the sustainability level of water environment treatment public-private partnership projects.
