# Hydraulic engineering
## MicroSim spec
- **Recommended sim type:** flow field
- **Microsimmability score:** 78/100
- **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below.
### Parameters (tunable controls)
- `Flow rate Q - 0 to 50 m^3/s`
- `Channel slope - 0 to 5 %`
- `Roughness / gate opening`
### What animates
Open-channel flow depth and [[Velocity|velocity]] evolve along a profile as flow rate, slope, and a gate opening change, switching visibly between subcritical and supercritical regimes.
### Learning objective
Relate channel flow depth and velocity to discharge, slope, and roughness.

> Hydraulic engineering as a sub-discipline of civil engineering is concerned with the flow and conveyance of fluids, principally water and sewage. One feature of these systems is the extensive use of gravity as the motive force to cause the movement of the fluids. ([Wikipedia](https://en.wikipedia.org/wiki/Hydraulic_engineering))

## Concept summary
Hydraulic engineering applies fluid mechanics to the conveyance and control of water through channels, pipes, and structures.
## Build checklist
- [ ] Claim it: set `status: in-progress` + `lease` + `leased_at`
- [ ] Write the child page explaining the concept (tie it back to process engineering)
- [ ] Finalize parameter ranges and defaults
- [ ] Implement the p5.js sketch (drawing + control regions)
- [ ] Add caption + the learning objective on the page
- [ ] Set `status: done`
## p5.js sketch
```javascript
// MicroSim: Hydraulic engineering
let controls = {};
function setup() {
// createCanvas(...); create sliders for the parameters above.
}
function draw() {
// background(...); read controls; render flow field; respond live.
}
```
