A Spatio-Temporal Neural Network Forecasting Approach for Emulation of Firefront Models

Abstract: Computational simulations of wildfire spread typically employ empirical rate-of-spread calculations under various conditions (such as terrain, fuel type, weather). Small perturbations in conditions can often lead to significant changes in fire spread (such as speed and direction), necessitating a computationally expensive large set of simulations to quantify uncertainty. Model emulation seeks alternative representations of physical models using machine learning, aiming to provide more efficient and/or simplifi… Show more

“…The model shows a promising result in basic conditions as the prediction closely matches the actual fire boundary. However, it is computationally demanding, requiring integration of many variables, and the model's accuracy varies widely across wildfires in different regions [16]. Another model, FIRECAST, is a convolutional neural network (CNN) used to predict the expected burned area of an active fire after 24 h [17].…”

“…We discuss a fire emulator (using a neural net architecture) that is hybrid in approach Bolt et al 2022). It is developed using Spark modeled fire perimeter inputs, having further hybrid data informing necessary spatial and temporal environmental inputs (weather, topography, vegetation and similar).…”
