Exoplanet Habitability Calculator vs Watershed Drainage Area Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
Exoplanet Habitability Calculator
Estimate an exoplanet's effective surface temperature and habitability based on its host star and orbital parameters. Use this when evaluating whether a discovered or hypothetical planet could support liquid water.
- Answers
- Surface Temperature (Kelvin)
- Inputs
- Stellar Luminosity, Stellar Temperature, Orbital Distance, Atmosphere Type
Watershed Drainage Area Calculator
Estimate the drainage area of a watershed from its length, average width, and a shape factor. Used by hydrologists and civil engineers to assess runoff, flood risk, and water resource capacity.
- Answers
- Annual Runoff Volume (million m³)
- Inputs
- Drainage Area, Annual Rainfall, Runoff Coefficient, Average Slope, Main Channel Length
