Promoting the continuous improvement of working and study conditions of the entire university community is one the basic principles and goals of the Universidad Politécnica de Cartagena. Such commitment to prevention and the responsibilities arising from it concern all realms of the university: governing bodies, management team, teaching and research staff, administrative and service staff and students. The UPCT Service of Occupational Hazards (Servicio de Prevención de Riesgos Laborales de la UPCT) has published a "Risk Prevention Manual for new students" (Manual de acogida al estudiante en materia de prevención de riesgos), which may be downloaded from the e-learning platform ("Aula Virtual"), with instructions and recommendations on how to act properly, from the point of view of prevention (safety, ergonomics, etc.), when developing any type of activity at the University. You will also find recommendations on how to proceed in an emergency or if an incident occurs. Particularly when carrying out training practices in laboratories, workshops or field work, you must follow all your teacher's instructions, because he/she is the person responsible for your safety and health during practice performance. Feel free to ask any questions you may have and do not put your safety or that of your classmates at risk.
The computer practices will occupy 80% of the subject. There will be a total of 10 practices: CASE-STUDY: P1: Flow between two trenches. Comparison between numerical simulation and analytical solution. P2: Unconfines aquifer psteady flow when pumping. Comparison between numerical simulation and analytical solution. P3: Application of the tool "Modpath" to particles¿s trajectories. P4: Piezometry and hydraulic conductivity relationships. P5: Simulation of a river and relationship with the aquifer. Imperviou barriers. P6: Multilayered aquifers. Water table and piezometric level P7: Coastal aquifer P8: Complex scenarios. Coastal aquifers with pumping wells P9: Injection wells as a decontamination measures P10: 3D tool. This is guidance proposal. The teacher may propose other cases as an alternative During the development of the practices, the students will learn to manage the tools of the program Zone Budget, well, boundary condition, recharge, parameter, river, control point, modpath, etc. FIELD-TRIP SURVEY: Programming a piezometric survey in the Agua Amarga coastal aquifer. This activity is scheduled within the agreement between the UPCT and the Mancomunidad de los canales del taibilla (BOE 5316/2018) The technical visit consists of carrying out a piezometry and salinity field survey on the piezometric control network of Agua Amarga coastal aquifer surface. This is located next to the abstraction wells of Alicante I and II desalination plants, near the population of The Altet (south of the province of Alicante). This activity is programmed within the agreement between the UPCT and the Commonwealth of the Channels of the Taibilla " Seguimiento y vigilancia ambiental del Saladar de Agua Amarga y su entorno" (BOE 5316/2018).

IMPORTANT NOTE: In order to take into account the note corresponding to the evaluation of the computer practice report, at least 90% of the computer practice classes must have been attended. In order to consider the note of the field report, the technical visit must have been attended. Students who miss more than 50% of the computer sessions will lose the options to be evaluated and will only be entitled to an exam consisting of two practical cases to be solved in the computer room using the Visual Modflow software. The exam will have a maximum score of 5 out of 10, to which the test type and the technical visit report will be added.
