Screening of representative rainfall event series for long-term hydrological performance evaluation of grassed swales.

Evaluation of the hydrological performance of grassed swales usually needs long-term monitoring data. At present, suitable techniques for simulating the hydrological performance using limited monitoring data are not available. Therefore, current study aims to investigate the relationship between saturated hydraulic conductivity (K) fitting results and rainfall characteristics of various events series length.

Time-varying characteristics of saturated hydraulic conductivity in grassed swales based on the ensemble Kalman filter algorithm -A case study of two long-running swales in Netherlands.

Saturated hydraulic conductivity (K) of the filler layer in grassed swales are varying in the changing environment. In most of the hydrological models, K is assumed as constant or decrease with a clogging factor. However, the K measured on site cannot be the input of the hydrological model directly.

An integrated approach to decision-making variables on urban water systems using an urban water use (UWU) decision-support tool.

In response to pressing global challenges like climate change, rapid population growth, and an urgent need for sustainable infrastructure, cities face an immediate and crucial necessity to transition swiftly toward an integrated approach to managing urban water resources. This shift is not merely an option but an imperative, driven by the rapidly evolving urban landscape. In addressing this imperative, a crucial decision support tool that has emerged as an asset in the domain of urban water planning and management is the Urban Water Use (UWU) tool.

A comprehensive review on the long-term performance of stormwater biofiltration systems (SBS): Operational challenges and future directions.

Stormwater biofiltration systems (SBS) are a popular technology for mitigating the negative effects of urbanization on the hydrological processes and water quality in urban areas. However, little is known about SBS's long-term performance in actual field conditions. The findings of a review of the scientific literature on the long-term performance of SBS are presented in this paper.

Nitrogen absorption efficiency and mechanism in Arbuscular mycorrhizal fungi - Canna indica symbiosis.

Arbuscular mycorrhizal fungi (AMF) and its symbiosis with Canna indica on nitrogen (N) absorption was investigated for the remediation of contaminated soil. Canna indica plants with rhizome and leaf integrity intact were collected in spring and autumn seasons. To maintain the ideal nutrient composition, Hoagland concentrated nutrient solution was diluted with deionized water and additional nutrient solution was added periodically.

Flood resilience.

Three different conceptual frameworks of resilience, including engineering, ecological and social-ecological have been presented and framed within the context of flood risk management. Engineering resilience has demonstrated its value in the design and operation of technological systems in general and in flood resilient technologies in particular. Although limited to the technical domain, it has broadened the objectives of flood resilient technologies and provided guidance in improving their effectiveness.

Lessons learned from applying adaptation pathways in flood risk management and challenges for the further development of this approach.

Worldwide, an increase in flood damage is observed. Governments are looking for effective ways to protect lives, buildings, and infrastructure. At the same time, a large investment gap seems to exist-a big difference between what should necessarily be done to curb the increase in damage and what is actually being done.

Flexible engineering designs for urban water management in Lusaka, Zambia.

Urban water systems are often designed using deterministic single values as design parameters. Subsequently the different design alternatives are compared using a discounted cash flow analysis that assumes that all parameters remain as-predicted for the entire project period. In reality the future is unknown and at best a possible range of values for design parameters can be estimated.
