The spread rate and flame geometry of the forward and backward sections of a line-ignited fire front were measured in 94 plots 10\u201315 m wide. Measured head fire rate of spread, flame length and Byram\u2019s fire intensity varied respectively in the intervals of 0.3\u201313.9 m min\u20131, 0.1\u20134.2 m and 30\u20133527 kW m\u20131. Fire behaviour was modelled through an empirical approach. Rate of forward fire spread was described as a function of surface wind speed, terrain slope, moisture content of fine dead surface fuel, and fuel height, while back fire spread rate was correlated with fuel moisture content and cover of understorey vegetation. Flame dimensions were related to Byram\u2019s fire intensity but relationships with rate of spread and fine dead surface fuel load and moisture are preferred, particularly for the head fire. The equations are expected to be more reliable when wind speed and slope are less than 8 km h\u20131 and 15\u00b0, and when fuel moisture content is higher than 12%. The results offer a quantitative basis for prescribed fire management.<\/jats:p>","DOI":"10.1071\/wf08023","type":"journal-article","created":{"date-parts":[[2009,9,21]],"date-time":"2009-09-21T21:46:10Z","timestamp":1253569570000},"page":"698-710","source":"Crossref","is-referenced-by-count":97,"title":["Empirical modelling of surface fire behaviour in maritime pine stands"],"prefix":"10.1071","volume":"18","author":[{"given":"Paulo M.","family":"Fernandes","sequence":"first","affiliation":[{"name":"ACentro de Investiga\u00e7\u00e3o e de Tecnologias Agro-Ambientais e Biol\u00f3gicas (CITAB), Universidade de Tr\u00e1s-os-Montes e Alto Douro, Apartado 1013, 5001-801 Vila Real, Portugal."},{"name":"CCorresponding author.
