Special Issue Information

Dear Colleagues,

Most countries are nowadays facing an unprecedented pressure on water resources. The growing world population, expanding industry and agriculture, pollution, climate change and disproportionate water use all contribute to forecasts that, with current practices, the world will face a 40% shortfall between projected demand and available water supply by 2030. In this context, it is essential to rethink the methods of managing water, to improve the efficiency of its use, and consider new sources of safe water that can, in a cascading strategy, contribute to overcoming the current and future challenges.

This Special Issue focuses on the optimisation of water management and the treatment of wastewater for reuse in the agri-food and livestock sectors, as well as in urban and industrial activities. It also aims to cover recent developments and advances in all aspects related to the water domain, including, but not limited to, water and wastewater treatment, water reuse, irrigation, resources recovery, life cycle assessment, cost assessment, footprints, and case studies. In this Special Issue, original research articles and reviews are welcome.

We look forward to receiving your contributions.

Groundwater possesses a natural advantage as a reservoir, making it well-suited for storage. Introducing a water bank to the groundwater market not only reduces storage costs but also revitalizes the groundwater rights market, achieving synergy between the economic and ecological values of regional water resources. This study combines the core functions of a water bank to establish a theoretical framework for mechanisms concerning value appreciation and risk prevention. Approaching the topic from the perspectives of transaction costs and market price mechanisms, we employ the Monte Carlo algorithm for simulation to study the mechanistic impact of a water bank on the efficiency of the water market. It reveals that a water bank, compared to direct transactions between parties, can effectively reduce the number of transactions in the fragmented water rights market. Additionally, it effectively utilizes market transaction information to provide accurate pricing. Furthermore, we alter model parameters to explore the relationship between the average number of transactions in the market and supply–demand equilibrium. We also investigate how changes in the acceptable price range in the supply–demand market affect the pricing strategies of a water bank and open market pricing. These findings substantiate the necessity of developing a water bank in practice. Full article

Aquifers are a vital part of our water cycle and modeling groundwater flow is paramount for a number of environmental applications. Modeling requires the estimation of aquifer properties, which is mostly achieved by field pumping tests. Oscillatory pumping tests involve repeated pumping and injection of aquifer water, which generates a periodic head signal. We investigate the estimation of equivalent hydraulic conductivity (Keq) in an oscillatory pumping test with a multi-frequency excitation. Synthetic head data are generated from numerical simulations of pumping in heterogeneous aquifers and an inverse method is applied to estimate Keq. The method involves a Fast Fourier Transform (FFT) analysis for obtaining the spatial distribution of head amplitude and then matching the amplitudes using a semi-analytical solution of a homogeneous aquifer with conductivity Keq. We investigate the dependence of Keq on pumping frequency in view of the previous literature, which has found increasing values for higher frequencies. We did not find this increase in Keq with frequency and minor variations which were observed appear to be a result of numerical error. The result implies that oscillatory pumping field tests can be used for Keq estimation without any corrections for frequency dependence. Full article
