Broder J. Merkel – författare

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 Ecosystems2. Hydrochemistry and Isotopic Hydrology3. Groundwater Assessment and Management: mapping, exploration, abstraction and modelling4. Water Resources Sustainability and Climate Change5. Hydrologic Engineering and Urban Groundwater

This edited book gives a general overview on current research, focusing on geoenvironmental issues and challenges in hydrogeosciences in model regions in Asia, Europe, and America, with a focus on the Middle East and Mediterranean region and surrounding areas. This proceedings book is based on the accepted papers for oral/poster presentations at the 2nd Springer Conference of the Arabian Journal of Geosciences (CAJG-2), Tunisia 2019. It offers a broad range of recent studies that discuss the latest advances in geoenvironmental and hydrogeosciences from diverse backgrounds including climate change, geoecology, biogeochemistry, water resources management, and environmental monitoring and assessment. It shares insights on how the understanding of ecological, climatological, oceanic and hydrological processes is the key for improving practices in environment management, including the eco-responsibility, scientific integrity, and social and ethical dimensions. It is of interest to scientists, engineers, practitioners, and policymakers in the field of environmental sciences including climatology, oceanography, ecology, biogeochemistry, environmental management, hydrology, hydrogeology, and geosciences in general. In particular, this book is of great value to students and environment-related professionals for further investigations on the state of Earth systems.

Auch die zweite Auflage von „Grundwasserchemie" bietet als praxisorientierter Leitfaden einen schnellen Einstieg in die thermodynamische Modellierung. Neben einem minimalen theoretischen Hintergrund liegt der Fokus auf praktischen Beispielen mit dem Computerprogramm PHREEQC. In der Neuauflage sind nun zusätzlich die Möglichkeiten des CD-MUSIC Konzepts zur Oberflächenmodellierung erklärt. Beispiele zum reaktiven Stofftransport umfassen nicht nur den 1d Transport in PHREEQC, sondern auch ein 3d Beispiel mittels PHAST und der graphischen Benutzeroberfläche WPHAST. Unsicherheiten thermodynamischer Daten können mit Hilfe des Programms LJGUNSKILE modelliert werden. Wie in der ersten Auflage helfen detaillierte Beschreibungen der Lösungen dem Nutzer, Schritt für Schritt von einfachen hin zu immer komplexeren hydrogeochemischen Modellierungen zu gelangen. Alle Programme sowie die Lösungen zu den Aufgaben befinden sich auf der CD zum Buch.
