Special Issue Information

Dear Colleagues,

Increasing world population is one of the major causes of environmental degradation and water security. Water security issues have been more salient in this century (e.g., water rights, water supply and storage safety, adequacy of quantity and quality of water, effective water use and irrigation, etc.). One needs to know the current status of water resources and the challenges of water security before developing creative and effective solutions to meet current and future water resource challenges.

Protecting the water and wastewater treatment infrastructure is key to maintaining the public health and environmental benefits of safe and clean water. For example, an effective system that can detect and respond, in a timely manner, to drinking water contamination threats needs to be designed. The coordination of the water sector with emergency services sector and an information tool that contains a comprehensive database and analytical methods for dealing with water contaminants are also important for preparedness, response, remediation, and recovery for water contamination events.

In the past few decades, significant changes in precipitation patterns and distribution (caused by climate change) have been identified. These affect the availability of water and increase the frequency of water-related disasters. In response to the impact of climate change, risk assessment methodologies need to be developed, and consequence analysis should be conducted to analyze the potential disaster-related health and economic consequences. Integrated models, such as the Integrated Water Resources Management (IWRM), can be used to assess water security by addressing tradeoffs among water users from agriculture, industry, households, and ecosystems.

Moreover, in the face of water service interruptions (due to natural or manmade disasters), water sectors and communities should work together to enhance the resiliency of drinking water and wastewater utilities. The interaction between water science and water policy will ensure water safety and supply, and the security of water environments can be achieved by tracking nutrient enrichment of water resources, climate change adaptation, flood mitigation, and other adaptive environmental management. Overall, this Special Issue will cover issues on water security and resiliency in terrestrial and freshwater environments, the applications of hydrologic sciences, and new water technologies for sustainability.

This study proposes a framework for estimating pollutant flux in an estuary. An efficient method is applied to estimate the flux of pollutants in an estuary. A gauging station network in the Danshui River estuary is established to measure the data of water quality and discharge based on the efficient method. A boat mounted with an acoustic Doppler profiler (ADP) traverses the river along a preselected path that is normal to the streamflow to measure the velocities, water depths and water quality for calculating pollutant flux. To know the characteristics of the estuary and to provide the basis for the pollutant flux estimation model, data of complete tidal cycles is collected. The discharge estimation model applies the maximum velocity and water level to estimate mean velocity and cross-sectional area, respectively. Thus, the pollutant flux of the estuary can be easily computed as the product of the mean velocity, cross-sectional area and pollutant concentration. The good agreement between the observed and estimated pollutant flux of the Danshui River estuary shows that the pollutant measured by the conventional and the efficient methods are not fundamentally different. The proposed method is cost-effective and reliable. It can be used to estimate pollutant flux in an estuary accurately and efficiently. Full article
