Workshop description

The offered Workshop includes an introduction to needed Modern Hydrogeology techniques to define, manage and control groundwater and environmentally related issues. As groundwater is a major source in the world and presents a particular concern in arid and semi-arid terrains as the MENA region, the Workshop includes discussion of basic tools, which introduce the Flow Systems methodology. Observed environmental issues are presented as a key to understand groundwater flow functioning. The relative modern conception that groundwater circulates in different paths in 3D provides with alternative tools to define how groundwater issues may be defined and controlled. Any reliable groundwater functioning model should comply with all of the components of the environment (such as soil type, vegetation, water chemistry, isotope content, lithology, hydraulics, basement rock position, etc). The identification and usage of direct and indirect indicators of the flow systems will be discussed using a wide system view. Practical applications of the flow systems include efficient groundwater extraction and an integrated water management practice. The main philosophy of the Workshop is twofold: i) discuss and support participants on basic, simple and practical tools to be derived from data obtained during any related hydrogeological field-work, and ii) to understand flow system components prior to a modelling analysis. Workshop participants will be conversant with basic information to be used to define an agreeable conceptual combined groundwater and surface flow model. Available field information usually represents flow systems components (recharge-transit-discharge) and their relative importance from local to regional scales perspective. Methodology to be discussed includes available elements of Geology, Hydraulics, Hydrology, Chemistry, Isotopes as well as physical (soil) and biological (vegetation) data; information that manifests the presence of groundwater within related constrains found in arid and semi-arid environments. The 48 hours introductive Workshop covers theoretical processes and modelling as applied to practical field issues through power-point presentations, discussions and field activities (groundwater sampling and flow systems evidence). Several international published papers are used as Workshop material and presented in a CD; the power-point presentations of the Workshop topics, models used and videos presented are also included in the CD. Reading material will be distributed two weeks before the start of the start of the Workshop to allow participants to be conversant with flow system principles. Study cases are expected to be presented by the participants for general discussion during the Workshop.
