Historical data, models, and scenarios can aid in estimating hydrological parameters and designing criteria for the structure, enhancing its resilience and performance in varying conditions.

A défaut d'un évènement historique suffisamment connu, les méthodes hydrologiques s'appuient en général sur des approches statistiques dont l'hypothèse sous-jacente est la stabilité des facteurs d'impact de l'hydrologie. Cette hypothèse est bien-sûr fausse de nos jours du fait notamment de l'évolution rapide du climat. Il est donc primordial à ce stade de l'étude de tester la sensibilité des modèles utilisés aux paramètres d'entrée, notamment vis-à-vis du changement climatique. Cela ne permettra pas d'être plus précis mais cela permettra d'avoir une vision des avenirs possibles.

Hydrological factors are important to avoid wars! That is what came to mind when I saw the article title. Water doesn't respect borders, so rivers and lakes often flow through multiple countries. Understanding the hydrological factors that affect these shared water sources helps countries work together to manage them fairly. For example, if one country builds a dam, it can affect the water flow to another country downstream. By studying the hydrological factors together, countries can negotiate agreements that ensure everyone has access to the water they need, helping to prevent conflicts and promote peace.

Un ejemplo de estructuras hidráulicas que impactan significativamente el ambiente, son los reservorios y embalses artificiales. La inundación de grandes áreas que ocasionan el desplazamiento de comunidades y especies animales y vegetales, son una muestra del gran impacto que se puede generar al implementar una obra de este tipo. Es por esto que una evaluación y planeación adecuada antes de implementar las obras, puede ayudar a mitigar los impactos que se tendrán sobre el entorno. Para la toma de decisiones, podemos apoyarnos de preguntas tales como ¿Se disminuirá la cantidad de agua en la zona? ¿Habrá desplazamiento de especies o comunidades en el área de influencia? ¿Se modificara drásticamente el ecosistema?

Environnement et social sont souvent liés mais il convient selon moi au contraire de les distinguer, au risque que les personnes touchées par le projet pensent qu'elles ne sont qu'un paramètre parmi d'autres.

Choosing a site for a hydraulic structure requires a delicate balance between engineering needs and environmental stewardship. Consider the impact on local ecosystems, water quality, and wildlife.

Sur un projet d'ouvrage hydraulique, il est probable qu'il y ait une forte opposition entre les partisans et les personnes opposées, sachant que la plupart des partisans seront souvent les personnes positivement impactées, les personnes opposées, des personnes pour qui l'impact sera négatif (NIMBY...) et aussi qui ne seront pas concernées par le projet mais qui jugent qu'il n'est pas adapté. On arrivera difficilement à faire changer d'avis un opposant mais on pourra faire en sorte de présenter le projet de façon honnête et argumentée.

Engaging with stakeholders is vital in site selection for hydraulic structures.

One of the most important factors to consider is the hydrological characteristics of the site, such as the water availability, demand, and variability. 

Risk Factor: Location of critical infrastructure plays an essential role in the estimate of possible risk. For example, dams should be located based on risk assessment study for probable economic and human life loss. A large dam at upstream of residential/metropolitan are poses a high risk in case of failure causing significant losses to life and properties. In addition, a good site for a high risk hydraulic should be easy to secure, monitor, and protect against vandalism or terrorism.

Let’s simplify it. Picking a spot for a big water project, like a dam or canal, is like choosing the perfect garden spot in your backyard. First, you want to make sure it gets the right amount of sun and rain throughout the year, this is like checking the water flow and weather changes. Next, you look for solid ground that won’t shift or sink, ensuring the structure stays put. Accessibility matters too; just as you’d pick a garden spot easy to reach with your tools and water hose, the site needs to be reachable for building and upkeep. Lastly, we consider our neighbors—making sure the project doesn’t harm anyone’s home or the local wildlife. It’s all about finding that perfect balance for a lasting, beneficial addition to the community.

Podrían listarse los aspectos mas importantes a la hora de elegir un sitio para instalar una obra hidráulica de la siguiente manera: * Comparar el uso que se dará a la estructura frente a la disponibilidad tanto espacial como temporal de agua en los alrededores. * Analizar aspectos técnicos tales como topografía, características del suelo, localización, disponibilidad de recursos para su construcción, etc. * Garantizar que la estructura impacte lo menos posible el ecosistema circundante. * Considerar que se tengan los recursos económicos para su construcción. * Garantizar voluntad política en caso de la participación del estado en el proyecto. * Realizar una adecuada socialización del proyecto con las entidades o comunidades a beneficiar.

When selecting a site for a hydraulic structure, there are several key factors to consider. These include the topography of the area, soil conditions, water availability, flood risk, environmental impact, and proximity to transportation networks. It's important to assess these factors to ensure a suitable and sustainable location for the hydraulic structure.

Au-delà des éléments mentionnés plus haut (qui quantifie l'impact de l'environnement du site sur l'ouvrage), il est également important de quantifier l'impact de l'ouvrage sur son environnement (ce qui se trouve à proximité) et sur l'environnement en général. Aucun projet n'est neutre. Il est donc nécessaire de quantifier tout ce qu'apporte l'ouvrage et tout ce qu'il fait perdre. Sans une vraie analyse globale, nous sommes à la merci de demi-décisions et du syndrome NIMBY (not in my backyard).

Additional considerations include long-term sustainability and climate change impacts. Understanding future shifts in weather patterns, water availability, and environmental regulations can help in designing structures that are resilient and adaptable. By taking a holistic view that incorporates emerging challenges, you can ensure that the hydraulic structure remains functional and beneficial for decades.
