Special Issue Information

Dear Colleagues,

An equitable supply of drinking water to the citizens and safe disposal of storm and wastewater originated from the city, which alongside other critical economic infrastructures for communication and transportation, are the responsibility of any municipal body. Water networks are laid in the city to distribute treated water to consumers at their location with the stipulated pressures, quantities and quality throughout the design period. Similarly, a combined or separate wastewater collection system is planned and laid in the city to collect and safely dispose of the stormwater and wastewater originating after the use of water by citizens. These networks consume the major portion of the total outlay of any municipal water supply or drainage system. Hence, their optimal design and management are essential, given other competing demands on limited public funds. As these networks are typically designed for periods of 30-50 years, the ability to cope with uncertainties and their satisfactory performance in the initial stage when the flows are less are essential to the hydraulic performance criteria.   

Climate change observed in the recent past has added a new dimension to uncertain parameters, especially affecting the design of the drainage system due to an increase in the frequencies and intensities of rainfall extremes. These hydrological uncertainties also affect the storage in impounding reservoirs and thereby the performance of the water distribution network (WDN) due to the limited volume of water available at the source. Other uncertainties include the predictions of nodal demands and pipe roughness coefficients, and the consequences of pipe, pump and other component failures.

In addition to the inherent complexity due to the uncertainty alluded to previously, major challenges are also associated with large networks comprising thousands of elements. We look forward to original contributions in a Special Issue on Water Distribution and Drainage Networks, on topics including but not limited to:

  • WDN tank siting, sizing and operation;
  • Operational management and control;
  • Active control of combined sewer systems;
  • Sustainable drainage systems;
  • Practical optimization methods applied to large real-world systems;
  • Water quality concerns;
  • Advanced skeletonization methods;
  • Model calibration;
  • Design and operation of intermittent water supply systems;
  • Water loss management and demand estimation;
  • Pressure management in water networks;
  • Accurate and surrogate performance measures;
  • Data acquisition and smart meters;
  • Pressure-driven simulation;
  • Long-term sustainable infrastructure renewal;
  • Infrastructure resilience;
  • Application of soft-computing techniques.

The roughness of the aqueduct in the Middle Route of the South-to-North Water Diversion Project has increased due to factors such as the natural aging of concrete and biological attachment. To increase the flow capacity of the project, a roughness reduction test was carried out in April 2021 by installing a nano-rubber coating on the Fangshui River aqueduct, which consists of three aqueduct bodies arranged in parallel. Before and after the test, as well as two years after the test, three field observations were conducted. The analysis revealed that compared to aqueduct body 2, which was only cleaned of surface attachments, after excluding the difference in the background roughness, the nano-rubber coating reduced the roughness of aqueduct body 1 by 0.0013 (10.00%). After two years of operation, the roughness was 0.0010 (7.41%) lower, indicating that the nano-rubber coating had a good and lasting effect on the roughness reduction. The roughness field observation results are sensitive to flow rate and water level measurement errors. For aqueducts with a low head and a high flow rate similar to those of the Fangshui River aqueduct, non-contact measuring instruments should be preferentially utilized, and sufficiently accurate flow rate measurements should be ensured to improve the accuracy of the roughness calculation.

The main canal of the middle route of the South-to-North Water Diversion Project has the risk of excess head loss in crossing water-conveyance structures, but the assessment of this risk faces difficulties such as the lack of sufficient monitoring points inside the structures, the current water-conveyance flow rate being lower than the design maximum flow rate, and the lack of verification of monitoring data. Monitoring data of the main canal were collected in 2022, prototype observations were carried out, the monitoring data were verified, and a method for calculating the head loss using the combined head loss coefficient was proposed. The assessment of 143 structures showed that 40 structures had excess head losses, including 31 inverted siphons, four aqueducts, four underdrains, and one culvert. The 143 structures had a total residual head of 3.05 m, accounting for 9% of the distributed head. In addition to natural aging, freshwater mussel and algal attachment, sediments, and undesirable flow regimes were all important influencing factors that caused the head loss to increase. It is recommended to take measures such as regular removal of sediments and algae and freshwater mussel attachments, optimization of inlet and outlet shapes, and application of roughness-reducing materials.
