WF22083Examining the effect of moisture thresholds on post-fire water-repellent soil: a large-scale modelling approach applied to the Upper Arroyo Seco watershed, California, USA

Nawa Raj Pradhan and Ian Floyd

 

At a watershed scale, the impact of wildfires on runoff following a precipitation event is greatest when the soil is dry and decreases sharply as soil moisture increases. Once the post-wildfire soil moisture reaches the threshold value of 0.25 m³/m³, flooding due to water repellency is no longer significant.

WF23028An evaluation of wildland fire simulators used operationally in Australia

P. Fox-Hughes , C. Bridge, N. Faggian, C. Jolly, S. Matthews, E. Ebert, H. Jacobs, B. Brown and J. Bally

 

Australian fire and land management agencies use fire simulators to predict characteristics of fires in the landscape, and require evaluation of simulator accuracy. Simulations of fire spread were assessed against observations. Inputs were perturbed to evaluate simulator sensitivity. Against the evaluation measures, no simulators proved universally superior to the others.

WF23151Firebrand burning under wind: an experimental study

Weidong Yan, Naian Liu, Hong Zhu , Haixiang Chen , Xiaodong Xie, Wei Gao and Zhihao Du

 

Knowledge about firebrand burning characteristics is essential for predicting the flight distance and trajectory for transport. This work studies the flaming and smouldering burning of firebrands under forced convection. Models are established for burning rate, projected area and surface temperature of firebrands, and applied to predict firebrand transport.

WF23174Linking crown fire likelihood with post-fire spectral variability in Mediterranean fire-prone ecosystems

José Manuel Fernández-Guisuraga , Leonor Calvo, Carmen Quintano, Alfonso Fernández-Manso and Paulo M. Fernandes

 

Satellite products with a direct physical meaning were accurate for estimating fire behaviour (surface fire, intermittent crown fire, and continuous crown fire) of past wildfire events across large burned Mediterranean ecosystems. This has major implications for anticipating post-fire ecosystem responses (e.g. delayed tree mortality).

WF23104A national accounting framework for fire and carbon dynamics in Australian savannas

Keryn I. Paul and Stephen H. Roxburgh

 

Savanna fire management has proved to be an effective mechanism for reducing greenhouse gas emissions and increasing carbon storage in ecosystems. In this study, we calibrate the FullCAM carbon accounting model with extensive field data to improve the model’s representation of fire impacts and carbon dynamics in Australian savannas, and to facilitate carbon accounting at project to national scales.

WF23142Australian Fire Danger Rating System: implementing fire behaviour calculations to forecast fire danger in a research prototype^†

B. J. Kenny, S. Matthews, S. Sauvage, S. Grootemaat, J. J. Hollis and P. Fox-Hughes

 

A spatially explicit forecast calculation system was designed and implemented to assess a new fire danger rating system for Australia based on fire behaviour models, weather inputs and a national fuel spatial data layer. This article is part of a collection about the Australian Fire Danger Rating System.

This article belongs to the Collection Australian Fire Danger Rating System.

WF23116The initiation of smouldering peat fire by a glowing firebrand

Shaorun Lin , Tianhang Zhang, Xinyan Huang and Michael J. Gollner

 

This work evaluated the propensity for spotting ignition of peat soil by a single glowing firebrand. We found that a new smouldering fire on the peat layer can be easily initiated by a firebrand that may fly over a firebreak to quickly expand burning regions in peatland.

WF23118Modification of the Rothermel model parameters – the rate of surface fire spread of Pinus koraiensis needles under no-wind and various slope conditions

Daotong Geng, Guang Yang, Jibin Ning, Ang Li, Zhaoguo Li, Shangjiong Ma, Xinyu Wang and Hongzhou Yu

 

The ROS of surface fire in Pinus koraiensis plantation was measured in the laboratory for different fuel loads, fuel moisture contents, and slope conditions. Fuel particle and environmental parameters in the Rothermel model were modified. The modified I_R and ϕ_S parameters significantly improved the Rothemel model prediction accuracy.

WF23134Fire and geodiversity

Ruby O. Hoyland , Melinda T. McHenry and Erin A. Foster

 

Geodiversity provides valuable benefits through its existence and function. Fire can degrade geodiversity elements in several ways, on vast spatial and temporal scales, with implications for geoconservation and protected areas management. Understanding recovery rates of geodiversity elements, and the cumulative impact of fire on geodiversity, requires further research.

WF23095Heat input determines the response and rapid recovery of post-fire soil microbial biomass

Rong She, Rong She, Jing-Chao Li , Jing-Chao Li , Xin Zhang, Xin Zhang, Yao-Quan Yang, Yao-Quan Yang, Fa-Ping Zhou, Fa-Ping Zhou, Davide Fornacca , Davide Fornacca , Xiao-Yan Yang, Xiao-Yan Yang, Wen Xiao and Wen Xiao

 

Recovery of soil microbes is crucial for the entire forest ecosystem following a fire. Our research, using simulated burns, revealed that soil microbial biomass began to recover only 20 days post‐disturbance, with subsurface soil microbes playing a key role. Heat indicators were found to more significantly influence microbial responses than soil physiochemical properties.

WF22113Assessing wildfire risk to critical infrastructure in central Chile: application to an electrical substation

Gonzalo Severino , Andrés Fuentes , Alejandro Valdivia, Fernando Auat-Cheein and Pedro Reszka

 

A methodology offering a comprehensive interpretation of wildfire risk considering both wildfire likelihood and asset vulnerability is proposed. The former is estimated with an event tree, while the latter is considered as the ignition probability of a polymeric fuel within a critical infrastructure. Wildfire risk is ~10⁻⁴ events/year.

Scanning remote sensing instruments allow us to understand the processes contributing to extreme wildfire fire plume behaviours including the development of strong rotation in the smoke column and fire-generated clouds reaching deep into the atmosphere. These data help us understand which fires are prone to extreme fire behaviour.

We present a 19-year climatology of the Australian Fire Danger Rating System: Research Prototype (AFDRS_RP), recently implemented operationally throughout Australia. The climatology describes the typical spatial and temporal behaviour of the AFDRS_RP. It is important for users to improve familiarity with the new system, and to ensure it performs as expected.
