Special Issue Information

Dear Colleagues,

An increasing number of global challenges, including climate change, quality of life, and industrial development, require the sustainable use of water resources. The assessment of water resources requires accurate and innovative methods to guarantee the quantity and quality of water for population, agriculture, industrial activities, and other purposes.

This Special Issue invites manuscripts that explore novel methodologies and technologies in the assessment of water resources. Topics of interest include, but are not limited to, machine learning applications, statistical modeling, integrated water resource management models, innovative hydrological approaches, and multi-disciplinary approaches.

The contributions to this Special Issue aim to develop solutions to the problems of water resource assessment to ensure sustainable management, address the challenges related to water scarcity, pollution, and climate change, and consider the legislative measures implemented, such as ecological flow and more.

These are some suggested topics for this Special Issue; however, they are not exhaustive:

  • Hydrological monitoring and modeling;
  • Water demand and usage evaluation;
  • Water risks and impact assessment (drought, flood, seasonal variations, groundwater depletion, contamination of freshwater sources);
  • Climate change impact assessment;
  • Integrated water resource management;
  • Circular economy in water management;
  • Machine and deep learning;
  • Multivariate analysis.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Assessment of Pesticide Contamination of Groundwater from Titu-Sarata Plain, Romania
by Crinela Dumitrescu, Claudia Stihi, Diana Costinel, Elisabeta Irina Geana, Corina Teodora Ciucure, Diana Ionela Popescu, Dan Tanislav and Petre Bretcan
Appl. Sci. 2025, 15(11), 5880; https://doi.org/10.3390/app15115880 - 23 May 2025

In Romania, groundwater is an important source of drinking water, especially in rural areas.

In Romania, groundwater is an important source of drinking water, especially in rural areas. This study investigated the concentrations of organophosphorus, carbamate, and triazine pesticides (OPs) along with organochlorine pesticides (OCPs) in groundwater samples collected from the Titu-Sarata Plain. Sensitive analytical techniques were employed, including Ultrahigh-Performance Liquid Chromatography coupled with Q Exactive™ HF Hybrid Quadrupole-Orbitrap™ Mass Spectrometry (UHPLC-Orbitrap-MS/MS) and Gas Chromatography–Mass Spectrometry (GC-MS). Environmental and human health risks were assessed in the case of pesticides that exceeded the maximum allowed concentration. The environmental risk assessment (ERA) revealed significant risks associated with Phosdrin, Phorate, and pp’DDE. Additionally, particular concerns arose from the presence of Aldrin and Dieldrin, which pose a high carcinogenic risk, especially through groundwater consumption in agricultural areas. The results of this research highlight the need for the implementation of a continuous quality monitoring program for groundwater in the agricultural regions that were studied. Full article

The Building Safe Water Use Plan promoted by the Macao Marine and Water Bureau aims to encourage property management entities to regularly maintain building water supply systems to ensure the safety and stability of drinking water. However, traditional laboratory testing methods are often time-consuming and labor-intensive, making real-time and efficient water quality monitoring challenging. To address this issue, this study proposes a Raspberry Pi-based multi-sensor system for rapid water quality detection and improved monitoring efficiency. This system integrates multiple sensors to measure key water quality parameters, such as pH, total dissolved solids (TDSs), temperature, and turbidity, while recording data in real-time. The data were continuously collected over a period of five months (July to November 2024). The collected data were analyzed and validated using machine learning algorithms, including Isolation Forest, Random Forest, Logistic Regression, and Local Outlier Factor. Among these models, Random Forest exhibited the best overall performance, achieving an accuracy of 98.10% and an F1 score of 98.99%. These results show that the dataset demonstrates high reliability in anomaly detection and classification tasks, accurately identifying deviations in water quality. This approach not only enhances the efficiency of water quality monitoring but also provides technological support for urban drinking water safety management. Full article

Recently, the frequency and intensity of extreme weather events have increased in many regions worldwide. Among them, floods, whose effects are devastating in many cases, have been recorded in Romania in the last few years. Built to reduce the flooding effects on the communities, structures such as embankments can sometimes accentuate the hazard. This article investigates such a situation and proposes solutions to reduce or even eliminate the flood impact on the community living in the Vărbilău Catchment in Romania. Recorded data series, field observations, GIS techniques, and hydraulic modeling were used to design the hazard maps and perform the 3D representations that illustrate the actual situation (when the small opening of the bridge favors the flooding) and the proposed solutions (extending the bridge opening and shortening the embankment). It is shown that adding seven pillars to the bridge would reduce the flooded surface by more than 1.5 times and the affected buildings’ surface by more than 3.5 times compared to the current situation.
