Water Security Under Climate Change: Challenges and Solutions . . . - MDPI Different countries face significant challenges in managing water-related natural hazards, such as floods and shortages, while ensuring adequate water quality and quantity to satisfy human needs and preserve ecosystems Climate change projections exacerbate this situation by intensifying the hydrological cycle, resulting in substantial changes in precipitation patterns, evapotranspiration, and
An Overview of Different Water Electrolyzer Types for Hydrogen Production While fossil fuels continue to be used and to increase air pollution across the world, hydrogen gas has been proposed as an alternative energy source and a carrier for the future by scientists Water electrolysis is a renewable and sustainable chemical energy production method among other hydrogen production methods Hydrogen production via water electrolysis is a popular and expensive method
Remote Sensing Techniques for Water Quality Monitoring: A Review - MDPI Freshwater resources are facing increasing challenges to water quality, due to factors such as population growth, human activities, climate change, and various human-made pressures While on-site methods, as specified in the USGS water quality sampling handbook, are usually precise, they require more time, are costly, and provide data at specific points, which lacks the essential comprehensive
Water | An Open Access Journal from MDPI Water is a peer-reviewed, open access journal on water science and technology, including the ecology and management of water resources, and is published semimonthly online by MDPI Water collaborates with the Stockholm International Water Institute (SIWI) In addition, the American Institute of Hydrology (AIH), The Polish Limnological Society (PLS) and Japanese Society of Physical Hydrology
Gaps in Water Quality Modeling of Hydrologic Systems - MDPI This review assesses gaps in water quality modeling, emphasizing opportunities to improve next-generation models that are essential for managing water quality and are integral to meeting goals of scientific and management agencies In particular, this paper identifies gaps in water quality modeling capabilities that, if addressed, could support assessments, projections, and evaluations of
Development of Electrochemical Water Splitting with Highly Active . . . Electrochemical water splitting is a feasible and effective method for attaining hydrogen, offering a mechanism for renewable energy solutions to combat the world’s energy crises due to the scarcity of fossil fuels Evidently, the viability and stability of the electrocatalysts are fundamental to the electrochemical water-splitting process However, the net efficiency of this process is
Fundamentals of Water Radiolysis - MDPI Radiolysis of water and aqueous solutions refers to the decomposition of water and its solutions under exposure to ionizing radiation, such as γ-rays, X-rays, accelerated particles, or fast neutrons This exposure leads to the formation of highly reactive species, including free radicals like hydroxyl radicals ( OH), hydrated electrons (e−aq), and hydrogen atoms (H ), as well as molecular
Validation of Inland Water Surface Elevation from SWOT Satellite . . . - MDPI The Surface Water and Ocean Topography (SWOT) satellite mission, jointly developed by NASA and several international collaboration agencies, aims to achieve high-resolution two-dimensional observations of global surface water Equipped with the advanced Ka-band radar interferometer (KaRIn), it significantly enhances the ability to monitor surface water and provides a new data source for
An Overview of Smart Irrigation Management for Improving Water . . . Global drylands, covering about 41% of Earth’s surface and inhabited by 38% of the world’s population, are facing the stark challenges of water scarcity, low water productivity, and food insecurity This paper highlights the major constraints to agricultural productivity, traditional irrigation scheduling methods, and associated challenges, efforts, and progress to enhance water use
Water Resources in Jordan: A Review of Current Challenges and Future . . . Jordan is facing significant challenges related to water scarcity, including overexploitation of groundwater, increasing demand, and wasteful practices Despite efforts to manage water resources, inadequate planning has resulted in ongoing water security concerns and deteriorating water quantity and quality To address water stress, Jordan has implemented measures such as desalination, dam
