[company_age]3.0[/company_age][employees]2-10 employees[/employees][description]SYMPLE is a company that offers a School of Hydrogeological Modelling hosted by professionals and academics from all over the world. The courses blend theory with practice in ways that are urgently needed in the industry. SYMPLE intends to teach an emerging paradigm supported by the latest ideas and software for data assimilation: "Starting from the problem and working backwards". This approach requires clearly identifying the groundwater management problem to be solved, identifying the type of data that has the greatest capacity to reduce uncertainties, and designing a simulation strategy that serves the decision-support imperative of quantifying and reducing those uncertainties. The modelling approach proposed by SYMPLE is quicker and less expensive because it is management targeted, only as complex as it needs to be to serve the decision-support demands, and supported by project-related strategies through specific software or workflows. That is, modelling should be complex enough to assimilate data and reduce uncertainty, but strategically simple because it is decision-focused.[/description][ps]School of Hydrogeological Modelling[/ps]
