The adding worldwide pressure on water coffers, under natural and anthropogenic conditions including climatic change requires an aggressive integrated multidisciplinary approach to address the scientific and societal issues involving water coffers. The structure, status, and processes of the groundwater system, which can only be acquired through scientific exploration sweats, are critical aspects of water resource operation. In this regard, hydro geochemical data as well as stable and radioactive isotope data give essential tools in support of water coffers operation.
Hence, there's a need for a close disquisition of water wisdom and policy “at the perimeters”. We need to know what happens at the interfaces of face water and groundwater, as well as brackish and saltwater, at global and watershed scales. Phenomena and possible changes are to be studied by contemporaneously addressing the volume and quality, wisdom and policy, and water and civilization aspects. Numerous of the present- day methodologies in water wisdom have been developed with limited data and data processing procedures. Due to the growth and enhancement of ultramodern technologies, a new generation of data has been made available to water resource operations, which have a much advanced spatial and temporal resolution.
Likewise, information technology development now provides access to an advanced position of computational capability, which calls for a reappraisal of introductory generalities for better diversification of models for colorful uses. Within the environmental lore’s, the operation of isotope methodology is being used to an everadding extent. An operation of this includes tracing the elaboration of a water mass from its origin as rush, through its recharge processes, and ending at its appearance in an aquifer. There's a particular focus on the operations at the face atmosphere and land biosphere atmosphere interfaces, since these are the spots of significant changes in isotope composition.
Besides this, isotopes can be used to determine the origin of specific solutes in groundwater. This type of operation generally involves stable isotopes. The force of stable isotopes, which has significant counteraccusations for water resource operation, has grown in recent times. The other main class of isotope operations was deduced from the decay of radioisotopes. Unlike stable isotope operations that exfoliate light on geochemical elaboration in aquifers, radioisotopes are primarily used to define the relative or absolute age of water in an aquifer. The date attained gives some substantiation of the hearthstone time of water in an aquifer once it has passed through the vadose zone. Besides this, isotope analyses can test and fine- tune an abstract hydrogeological model.
Methodologies Grounded on the use of isotopes in a full diapason of hydrological problems encountered in water resource assessment, development, and operation conditioning are formerly scientifically established and are an integral part of numerous water resource examinations and environmental studies. The conception of “Tracing” is applied for these methodologies, in which either naturally being isotopic species (environmental isotopes) or designedly introduced tracers are employed. In the last decades, there has been an adding interest in environmentally friendly tracers because a concern has surfaced about the operation of artificial tracers in submarine ecosystems due to their potentially negative impact on the terrain.
Thus, this Special Issue aims to announce and substantially deal with findings on the robustness or fitness-for- purpose regarding the applicability and use of isotopes in water resource systems, with respect to approaching problems and openings scientifically. Original exploration papers were named by a peer- review process with the purpose of rapid-fire, accessible and wide dispersion of results.
