Slope

Fuel density

Fire spreads cell to cell, biased downwind and uphill — the two dominant drivers of real wildfire rate-of-spread. Rotate the wind and raise the slope to see how a fire front elongates and races upslope. For training and situational awareness only.

Wind15 @ 90°

Slope10°

Governing equation

R = R_{0} (1 + ϕ_{w} + ϕ_{s}), ϕ_{w} = 0.60, ϕ_{s} = 0.22

Reading this result: Moderate wind and slope: the fire spreads roughly outward, with a gentle bias downwind and uphill.

Release rate (g/s)

Wind speed (m/s)

Action level (mg/m³)

A Gaussian plume estimates how a gas or vapor release disperses downwind. Stability class (A unstable to F stable) sets how fast the plume spreads. The dashed line is the protective action distance where concentration falls below your action level. Screening estimate only — use ERG and monitors on scene.

Protective distance>20 km

StabilityD neutral

Wind4 m/s

Governing equation

C (x, y) = \frac{50}{2 π 4 σ _{y} σ _{z}} exp (- \frac{y ^{2}}{2 σ _{y}^{2}})

Reading this result: Concentration falls off as the wind stretches and vertical mixing thins the plume — stronger wind and less stable air pull the protective distance in toward the source.

Walk speed

Speed1×

Occupants head for the nearest exit while pushing apart in crowds, so bottlenecks and congestion form at doorways — the effect that drives real egress times. Add or remove exits to see how total clearance time responds. Planning aid only.

v = 1.3 \overset{e}{^}_{exit} + 2.2 j \sum f_{ij}, \frac{N}{exits} = \frac{150}{2} = 75

Reading this result: Around 75 per exit — congestion starts to build at the doors, and adding an exit usually helps more than speeding people up.

Combines the radio horizon (1.23·(√h₁+√h₂), feet→miles) with a free-space link budget (EIRP minus path loss vs receiver sensitivity). Actual range depends on terrain, foliage, and buildings — treat this as a best-case planning estimate.

Governing equation

FSPL = 20 lo g_{10} (\frac{4 π d}{λ}) = 147 dB (d = 9.7 mi, f = 155 MHz)

Reading this result: Range is capped by the horizon at 9.7 mi — raising the base antenna helps more than adding power here.
