Special Issue Information

Dear Colleagues,

Water resilience represents a reliable water supply capability that can efficiently adapt and respond to change. In the Anthropocene, climate change, geology activities, or artificial interventions will inevitably result in dramatic changes of the water amount, water supply, water transport, and water usage. All these shocks or stresses test the water resilience in our reservoirs, cities, and countries all the time. Given that, water resilience plays a pivotal role to achieving the 2030 Sustainable Development Goal (SDG) 6 for the benefit of all human beings. This challenge requires the community to address this key question: How can we build more water-resilient cities?

To achieve this goal, we need a series of innovative studies on water resilience concept, theory, modelling, assessment, enhancement, datasets, software, hardware, and strategy. For example, more scientific evidence about the tipping point to our water system should be analysed to optimise resilience theory. Unpredictable rainfall, flooding, droughts, manmade pollution, and other water-related shocks and stresses on cities should be quantitatively modelled. Governors and other stakeholders also need to know how to accurately evaluate the resilience capability for each city or country. In addition society as a whole needs to answer how to build a sustainable and resilient water system for the future. All these questions involve the integration of much knowledge and the intersection of multiple disciplines, though the centre remains water science.

Topics of interest include but are not limited to the following:

  • Water resilience concept and theory framework;
  • Scientific evidence of water shocks;
  • Qualitative and quantitative modelling of water resilience systems;
  • Assessment of water resilience at different scales;
  • Enhancement approach for water resilience;
  • Standardized datasets;
  • Software with new ICT techniques for resilience research;
  • Innovative hardware for water resilience application;
  • Systematic strategies;
  • Resilience research driven by SDGs.

As the centerpiece of ecosystems and human societies, river basins are complex social–ecological systems (SESs) that depend on the natural flow regime and the hydrologic variability to adapt to changes and absorb disturbances. Anthropogenic and climate change disturbances destabilize river systems. Therefore, a resilience question arises: What is the carrying capacity of a river basin, i.e., how much disturbance can a river basin take until the system undergoes a regime shift? To answer this question, this study aims to identify regime shifts, thresholds, and the carrying capacity of the transboundary Rio Grande–Rio Bravo (RGB) basin using 110 years of monthly streamflow data. To address this research question, first, gauged (regulated) and naturalized streamflow data is collected; if naturalized flows are not available, they are calculated through streamflow naturalization. Second, streamflow standardization is estimated using the streamflow drought index. Third, a regime shift assessment is performed using Fisher Index, and fourth, the nonparametric Mann-Kendall test is used to assess the Sustainable Regime Hypothesis which evaluates regime shifts and alternative regimes. Results demonstrate that resilience thresholds are surpassed, and regime shifts, including early warning signals, occurred in multiple locations of a transboundary basin. The present study highlights the importance of assessing the carrying capacity of a river basin; hence, evaluating regime transitions, including identifying early warning signals and thresholds, is critical in managing for sustainability and ecological resilience of SESs. Looking ahead, the integration of ecological resilience theory into water management has the potential to recognize the sustainable carrying capacity of river basins at the local, regional, and international scale.

The water levels downstream of the Sai Gon and Dong Nai river in Southern Vietnam have been significantly changed over the last three decades, leading to severe impacts on urban flooding and salinity intrusion and threating the socio-economic development of the region and lives of many local people. In this study, the Mann-Kendall (MK) and trend-free prewhitening (TFPW) tests were applied to detect the water level trends and changepoints based on a water level time series at six gauging stations that were located along the main rivers to the sea over 1980–2019. The results indicated that the water level has rapidly increased by about 0.17 to 1.8 cm/year at most gauge stations surrounding Ho Chi Minh City, strongly relating to urbanization and the dike polder system’s impacts that eliminates the water storage space. In addition, the operation of upstream reservoirs has contributed to water level changes with significant consequences since the high-water level at Tri An station on the Dong Nai river occurs 1000–1500 times compared to 300–500 times before the operation. Although the effects of the flows from the sea are less than the two other factors, the local government should seriously consider water level changes, especially in the coastal regions. Our study contributes empirical evidence to evaluate the water level trends in the planning and development of infrastructure, which is necessary to adapt to future changes in Southern Vietnam’s hydrologic system.
