# eFlows Overview

[![Build Status](https://travis-ci.org/leogoesger/func-flow.svg?branch=master)](https://travis-ci.org/leogoesger/func-flow)

## About

The functional flows calculator (FFC) quantifies key aspects of the annual flow regime based on long-term daily streamflow time series data, producing a broad suite of descriptive functional flow metrics. These metrics are meant to characterize ecologically relevant components of a flow regime in a robust, objective manner to enable comparisons of streamflow across regions, natural stream classes, and various forms and magnitudes of flow alteration. The FFC generates metrics describing aspects of streamflow timing, magnitude, duration, frequency, and rate of change, organized into five seasonally-based functional flow components: 1) fall pulse flow, 2) wet-season flows, 3) peak magnitude flows, 4) spring recession flows, and 5) dry-season baseflow.

This project uses [Python3](https://www.python.org/) for its processing algorithm, [React](https://reactjs.org/), [Mapbox](https://www.mapbox.com/), and [D3](https://d3js.org/) for front end web development, and [Express](https://expressjs.com/), [Sequelize](http://docs.sequelizejs.com/), and [Postgres](https://www.postgresql.org/) for the server.

# Agent Instructions: 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:

```
GET https://eflow.gitbook.io/ffc-readme/master.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
