# Antecedentes de la evaporación y la precipitación en los embalses

## Cuantificación del flujo de evaporación y precipitación <a href="#quantifying-evaporation-and-precipitation-flow" id="quantifying-evaporation-and-precipitation-flow"></a>

**Pérdidas por evaporación** y almacenamiento adicional a través de **precipitación** son los principales componentes del balance de masa de un yacimiento. Las tasas de evaporación y precipitación se miden generalmente en duración/tiempo. En unidades métricas, esto es a menudo **mm/día**.

Para obtener las tasas de flujo volumétrico diario que se requieren para Pywr, estas tasas se multiplican por **Zona** del embalse. En las plantillas métricas de WaterStrategy, esta área se expresa generalmente en **Km2**.

**Para una plantilla que usa flow in&#x20;**<mark style="color:purple;">**MM3/día**</mark>**, es necesaria una conversión de 0.001 para obtener&#x20;**<mark style="color:purple;">**MM3/día**</mark>**.**

*Evaporación (mm/día)\* Área (km)\* 0.001 = MM3/día*

**Para una plantilla que usa el flujo en ml/día, no se requiere ninguna conversión para obtener ml/día.**

*Evaporación (mm/día)\* Área (km)\* 1 = ml/día*

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://water-strategy.gitbook.io/waterstrategy/espanol/tutoriales/creating-a-reservoir-system/adding-reservoir-details/background-on-evaporation-and-precipitation-on-reservoirs.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
