A method for mapping fire hazard and risk across multiple scales and its application in fire management.

Keane, Robert E.; Drury, Stacy A.; Karau, Eva C.; … - 2010

This paper presents modeling methods for mapping fire hazard and fire risk using a research model called FIREHARM (FIRE Hazard and Risk Model) that computes common measures of fire behavior, fire danger, and fire effects to spatially portray fire hazard over space. FIREHARM can compute a measure...

Structured Application of the Two-Point Method for the Estimation of Infiltration Parameters in Surface Irrigation.

Bautista, E.; Clemmens, A.J.; Strelkoff, T.S. - 2009

The two-point method is one of the best known procedures for estimating empirical infiltration parameters from surface irrigation evaluation data and mass balance, mainly because of its limited data requirements and mathematical simplicity. However, past research have shown that the method can...

A nonparametric/parametric analysis of the Universal Soil Loss Equation.

Sonneveld, B.G.J.S.; Nearing, M.A. - 2003

Due to its modest data demands and transparent model structure, the Universal Soil Loss Equation (USLE) remains the most popular tool for water erosion hazard assessment. However, the model has several shortcomings, two of which are likely to have prominent implications for the model results....
