Geoenvironmental processes in coastal areas and groundwater discharge to the sea. 1.5P. Identification of potential groundwater discharge areas on the Catalan coast 1.6. Geodynamic and hydrological processes in anthropic conditions: the international case study of the Ebro Basin.

Specific Objectives

In this topic, an introduction to the subject will be made as well as some basic geological concepts. In the second part, it will be explained how human activities can alter the natural cycle of water and also the concept of water budget or water balance, as a basic management tool and its application to a real case through a numerical model Rivers are a fundamental part of the hydrological cycle where not only water transport but also sediment takes place, which affects natural systems such as Deltas and beaches, but can also become a geological irrigation during floods. This topic will explain different methods for the measurement of flows, and estimation of the risk of flooding, as well as the natural and anthropic variables that affect and / or alter the transport of water and sediments in river courses. The case of pollution in the area of Flix will be explained and as an exercise you should stop and take into account where the sampling is done to determine the transport of the pollution taking into account the fluvial geodynamics Although in many cases subsoil resources may go unnoticed due to their low "visibility", they are important in multiple aspects beyond mining resources, construction materials or water to supply the population. This topic will explain the services provided by the subsoil with special emphasis on the importance of groundwater for the good condition of continental aquatic ecosystems, from rivers to wetlands. The different types of geothermal energy will also be explained, with special importance of very low enthalpy, which can be applied around the globe adapted to each geological context. Using the IGCC vizier (and Google Earth) and the information from the geological map of Catalonia, identify at least 5 areas/points where you think there will be ecosystems dependent on groundwater (wetlands, rivers, etc.) with a brief justification. This chapter will explain how the different contexts and geological formations condition the flow of water in the subsoil. The dynamics of coastal aquifers, marine intrusion (flow in variable density), corrective measures and considerations in the field will also be explained. The concentration of nutrients in groundwater is generally much higher than in rivers. Therefore, despite the fact that groundwater discharge flows to the sea may be quantitatively much lower than that of surface waters, its high concentration of nutrients, generally much greater than surface waters, has important implications for coastal ecosystems. This topic will explain how groundwater discharge to the sea works, its importance and quantification methods, both from a hydrogeological and oceanographic approach. Identify at least three areas of Catalonia where you would expect to find a greater discharge of groundwater and justify why based on the following data: Viewer Institut cartogràfic i geològic de Catalunya.

Its great geological, climatic, hydrological, ecological and social diversity has made it an international case study. This topic will explain the different impacts derived from the planning and management of water resources from an environmental and social point of view, starting at the head reservoirs until ending at the mouth of the Ebro Delta.

Topic 2.1: Introduction to GIS and basic QGIS course (free software) Topic 2.2: Application of QGIS to practical cases

Specific Objectives

GIS are computer systems that allow us to integrate, store, analyze, share and display widely varied information in a geo-referenced way. The appearance of GIS has marked a before and after in many fields of knowledge and is a fundamental tool for environmental management. This block will explain what GIS is and will provide the necessary bases to be able to use free QGIS software at a basic level. Real cases will be worked with the QGIS tool

3.1. Traditional tools in geological and geophysical prospecting 3.2. New on-site application tools: multi-parameter surveys and profiles, recently developed water sensors, new geophysical prospecting methods and fiber optics. 3.3. New remote tools: drones and satellite remote sensing. 3P. Analysis and assessment of real cases

Specific Objectives

This topic will explain what are the most common tools for conducting geological prospecting, as well as the most widely used geophysical methods (non-invasive methods) for underground exploration. Technological advances in recent years are revolutionizing existing options for characterizing and monitoring the subsoil. This topic will explain some recently developed methods for characterizing the subsoil in situ with some real examples. These advances have not occurred only in on-site tools, but especially through new remote sensing tools. In this class, an introduction to the subject will be made, comparing the advantages and disadvantages between the different platforms (drones vs. airborne vs. satellites) as well as some examples of applications for the study of the subsoil and environmental processes. Different examples of application and real cases of the methodologies explained in theory throughout block 3 will be explained and assessed.
