    Integrated Management of the Urban Water Cycle: A Synthesis of Impacts and Solutions from Source to Tap
    (MDPI, 2026-03-23) Marcoie, Nicolae; Iliesi, Elena; Barta, András-István; Raboșapca, Irina; Toma, Daniel; Boboc, Valentin; Balan, Cătălin-Dumitrel; Tofănică, Bogdan-Marian
    Urbanization fundamentally fractures the natural water cycle, leading to a cascade of interconnected problems including increased flood risk, degraded water quality, stressed groundwater resources, and inefficient distribution networks. Traditional, fragmented management approaches that address these issues in isolation have proven inadequate. This research argues for a paradigm shift towards an Integrated Urban Water Management (IUWM) framework anchored in the concept of the “river-aquifer-pipe network continuum”, treating these components as a single, dynamic hydrological and infrastructural entity. Drawing upon a series of detailed case studies from Eastern Romania, this paper synthesizes the systemic impacts of development across the entire urban water system. Evidence from the Prut, Olt, and Bahlui river basins demonstrate how channelization exacerbates flood peaks and leads to severe biochemical degradation. Hydrogeological modeling of the Gherăești-Bacău wellfield reveals the vulnerabilities of over-extraction, while analysis of the Iași water network highlights the challenge of water losses in the aging infrastructure. In response, a modern, multi-tool approach is consolidated into a practical, three-stage framework for action: Diagnose, Prescribe, and Optimize. This framework advocates for (1) a comprehensive diagnosis using a suite of predictive numerical models (a “digital twin”); (2) the prescription of foundational, nature-based solutions, such as floodplain restoration, to heal core ecological functions; and (3) the continuous optimization of engineered infrastructure using smart, real-time control technologies. The synthesis concludes that an integrated, data-driven, and collaborative approach is the only sustainable path forward. Future research should focus on formally coupling these diagnostic models to create true Digital Twins of urban water systems—an essential step towards building resilient, water-secure cities for the 21st century.

    Assessing Viticultural Parameters and Wine Quality in Relation to Climate Conditions
    (MDPI, 2026-03-19) Scutarașu, Andrei; Colibaba, Lucia-Cintia; Scutarașu, Elena-Cristina; Luchian, Camelia-Elena; Rotaru, Liliana; Filimon, Răzvan Vasile; Filimon, Roxana Mihaela; Cotea, Valeriu V.
    This study evaluates viticultural parameters of the Golia grape variety in relation to variable climatic conditions over the 2020–2024 period and analyzes their impact on wine quality. The data show significant climatic variability, with warming trends causing earlier flowering and ripening by 11–13 days. Grape production varied depending on climatic conditions, with 2021 and 2024 recording the highest number of shoots per trunk and increased fertility in 2024. Low winter temperature led to reduced bud viability and affected the overall health of the vines and harvest yields. Average annual precipitation, especially from the growing season, significantly influenced actual yield (AY), while higher annual temperatures and sunshine duration (Sun) resulted in lower grape weight. Greater sugar concentrations accumulated in years with higher temperatures, while higher acidity levels registered at lower temperatures. Higher precipitation (Pp) coupled with thermal accumulation promoted higher dry extract and alcoholic strength (AS), significantly enhancing the perception of honey notes (R2 > 0.7, p-value < 0.05). Furthermore, higher thermal regimes negatively impacted the expression of delicate aromatic compounds, diminishing specific notes such as rose and exotic fruits.
