Water Energy Food Nexus in Urbanizing Wetlands: Challenges and Solutions Explored through Choremes and Focus Maps Water (IF 3.4) Pub Date : 2024-03-22 Dragos Balaican, Katrin Teubner, Iuliana-Mihaela Tudor, Iulian Nichersu, Adrian Burada, Cristian Trifanov, Marian Tudor, Catalina Iticescu, Luminita Moraru, Puiu-Lucian Georgescu
Addressing complex interactions within water, energy, and food (WEF) resources, innovative tools for in-depth analysis and decision-making are imperative. This study introduces chorematic focus maps (CFMs) as a groundbreaking method to visualize and tackle the WEF nexus’s complexities, focusing specifically on the Danube Delta Biosphere Reserve (DDBR). By merging geospatial analysis with on-site validation

Machine-Learning-Based Prediction Modeling for Debris Flow Occurrence: A Meta-Analysis Water (IF 3.4) Pub Date : 2024-03-22 Lianbing Yang, Yonggang Ge, Baili Chen, Yuhong Wu, Runde Fu
Machine learning (ML) has become increasingly popular in the prediction of debris flow occurrence, but the various ML models utilized as baseline predictors reported in previous studies are typically limited to individual case bases. A comprehensive and systematic evaluation of existing empirical evidence on the utilization of ML as baseline predictors for debris flow occurrence is lacking. To address

Impact of Exogenous Indoleacetic Acid on Nitrogen Cycling-Associated Bacteria in the Rhizosphere and Eutrophic Water Surrounding Hydrocotyle vulgaris Lam Water (IF 3.4) Pub Date : 2024-03-22 Min Zhang, Wenliang Xiang, Feifei Song, Haoyu Zhu, Ting Cai, Jie Tang, Qing Zhang
Phytohormones have the potential to enhance the nutrient removal efficiency of aquatic plants in wastewater treatment. Here, we investigated the impact of indoleacetic acid (IAA) on nitrogen removal by Hydrocotyle vulgaris Lam during the remediation process of eutrophic water. This investigation involved evaluating the biological indicators of H. vulgaris Lam, the nitrogen salt removal efficiency in

Comparing Remote Sensing and Geostatistical Techniques in Filling Gaps in Rain Gauge Records and Generating Multi-Return Period Isohyetal Maps in Arid Regions—Case Study: Kingdom of Saudi Arabia Water (IF 3.4) Pub Date : 2024-03-22 Ahmed M. Helmi, Mohamed I. Farouk, Raouf Hassan, Mohd Aamir Mumtaz, Lotfi Chaouachi, Mohamed H. Elgamal
Arid regions are susceptible to flash floods and severe drought periods, therefore there is a need for accurate and gap-free rainfall data for the design of flood mitigation measures and water resource management. Nevertheless, arid regions may suffer from a shortage of precipitation gauge data, whether due to improper gauge coverage or gaps in the recorded data. Several alternatives are available

Analyzing Water Leakages in Parallel Pipe Systems with Rapid Regulating Valve Maneuvers Water (IF 3.4) Pub Date : 2024-03-22 Vicente S. Fuertes-Miquel, Alfonso Arrieta-Pastrana, Oscar E. Coronado-Hernández
Water utilities face the challenge of addressing physical leaks generated from the aging of water distribution systems and the need for more innovative practices to manage water infrastructure efficiently. Water leakages are typically modeled using extended period simulations based on Bernoulli’s equation. However, this approach must be revised since traditional methods do not appropriately simulate
