To understand hydrochemistry and to analyze natural as well as man-made impacts on aquatic systems, hydrogeochemical models have been used since the 1960’s and more frequently in recent times. Numerical groundwater flow, transport, and geochemical models are important tools besides classical deterministic and analytical approaches. Solving complex linear or non-linear systems of equations, commonly with hundreds of unknown parameters, is a routine task for a PC. Modeling hydrogeochemical processes requires a detailed and accurate water analysis, as well as thermodynamic and kinetic data as input. Thermodynamic data, such as complex formation constants and solubility products, are often provided as data sets within the respective programs. However, the description of surface-controlled reactions (sorption, cation exchange, surface complexation) and kinetically controlled reactions requires additional input data. Unlike groundwater flow and transport models, thermodynamic models, in principal, do not need any calibration. However, considering surface-controlled or kinetically controlled reaction models might be subject to calibration. Typical problems for the application of geochemical models are: speciation determination of saturation indices adjustment of equilibria/disequilibria for minerals or gases mixing of different waters modeling the effects of temperature stoichiometric reactions (e.g. titration) reactions with solids, fluids, and gaseous phases (in open and closed systems) sorption (cation exchange, surface complexation) inverse modeling kinetically controlled reactions reactive transport Hydrogeochemical models are dependent on the quality of the chemical analyses, the boundary conditions presumed by the program, theoretical concepts (e.g.

This book comprises the selected papers from the 1st Springer Conference of the Arabian Journal of Geosciences (CAJG-1), Tunisia 2018. The volume is of interest to all researchers and practitioners in the fields of Hydrology, Hydrogeology, Hydrochemistry, Water Resources and Hydrologic Engineering. Water is a dynamic, finite, and vulnerable but resilient natural resource to be protected in an environmentally sustainable manner. Water systems in different frameworks requires a comprehensive understanding of climatology, geology, hydrogeology, hydrochemistry, hydrodynamics, and surface hydrology. In addition, it is highlighted the role of the variability and climate change in water systems. Furthermore, water has a vital significance to the entire socio-economic sector. This volume offers an overview of the state-of-the-art related to water science and technology in model regions in Europe, Africa, Middle East, Asia and America, but mainly focuses on the Mediterranean environment and surrounding regions. It gives new insights on characterisation, evaluation, quality, management, protection, modelling on environmental hydrology, groundwater, hydrochemistry, sustainable water resources studies and hydrologic engineering approaches by international researchers. Main topics include: 1. Hydrology, Climatology and Water-Related Ecosystems 2. Hydrochemistry and Isotopic Hydrology 3. Groundwater Assessment and Management: mapping, exploration, abstraction and modelling 4. Water Resources Sustainability and Climate Change 5. Hydrologic Engineering and Urban Groundwater.
