El estudio de impacto ambiental contendrá información sobre la localización del proyecto, y los elementos abióticos, bióticos y socioeconómicos del medio que puedan sufrir deterioro por la respectiva obra o actividad, para cuya ejecución se pide licencia, y la evaluación de los impactos que puedan producirse. Además, incluirá el diseño de los planes de prevención, corrección y compensación de impactos y el plan de manejo ambiental de la obra o actividad.” ANLA |
| PMA | Plan de manejo ambiental - El Plan de Manejo Ambiental se realizará para mitigar los impactos ambientales que deterioran el medio ambiente y los recursos naturales por efecto de la operación y el funcionamiento del proyecto, desde el punto de vista físico, biótico y social. El Plan de Manejo Ambiental debe establecer el grado de vulnerabilidad de los ecosistemas y comunidades localizados en el área de influencia que se determine para el proyecto. Los impactos deben identificarse, dimensionarse y evaluarse cuantitativa y cualitativamente, de tal manera que se establezcan con la mayor precisión. El plan establece de manera detallada, las acciones que se implementarán para prevenir, mitigar, corregir o compensar los impactos y efectos ambientales negativos que se causen por el desarrollo de un proyecto, obra o actividad.

| Stream bed (Cauce) | A stream bed or streambed is the channel bottom of a stream or river, the physical confine of the normal water flow. The lateral confines or channel margins are known as the stream banks or river banks, during all but flood stage. Under certain conditions a river can branch from one stream bed to multiple stream beds. Concavidad del terreno, natural o artificial, por donde corre un río, un canal o cualquier corriente de agua. |
| Freeboard (Fb) | Freeboard in water channels is the vertical distance between the normal water surface and the top of the channel bank, acting as a crucial safety margin to prevent overtopping from surges, waves, or unexpected flow increases, ensuring water stays within the channel and doesn’t flood surrounding areas or cause structural damage, often a percentage of channel depth or a fixed height, varying by application like irrigation or flood control. It’s a design element to manage uncertainties, from wind action to operational errors, keeping hydraulic structures like flumes and weirs functioning correctly. |

| Elevation area & Elevation volume curves in reservoirs | Elevation-Area and Elevation-Volume curves are graphical tools used by engineers to define the physical geometry of a reservoir. They represent how much water surface area and total water capacity correspond to any given water level elevation, which is critical for planning, flood control, and power generation. The calculations in QGIS can be perform throught the Processing Toolbox / Raster Terrain Analysis / Hypsometric curves or with the complement Surface Water Storage / Processing Toolbox / Area-Volume-Elevation graph. |
