Journal ArticleDOI
TDR calibration of organic forest floor media
TL;DR: In this paper, a time domain reflectometry (TDRD) calibration for 25 forest floor samples of five different forest stands was carried out and linear regression was used to estimate the volumetric water content from the refraction index.
Journal ArticleDOI
Coevolution of nonlinear trends in vegetation, soils, and topography with elevation and slope aspect: A case study in the sky islands of southern Arizona

TL;DR: In this article, a landscape evolution model that couples pedogenesis and topographic development over geologic time scales, with rates explicitly dependent on vegetation density, was developed to test if eco-pedo-geomorphic feedbacks drive this pattern.
Journal ArticleDOI
Quantification of uncertainty in pedotransfer function-based parameter estimation for unsaturated flow modeling
TL;DR: In this paper, the PTF input uncertainty is quantified by assuming that the cokriging estimates follow a normal distribution, and the authors show that additional sample acquisition for the PTP input variables would have a more favorable impact on reduction of the parameter estimation uncertainty than collecting additional soil hydraulic parameter measurements for PTF development.
Journal ArticleDOI
Forest floor evaporation in a dense Douglas fir stand
Marcel G. Schaap,Willem Bouten +1 more
TL;DR: In this article, the authors used the Penman-Monteith approach to model the evaporation rates as well as the temperature difference between forest floor surface and air at 1 m height.
Journal ArticleDOI
Forest floor water content dynamics in a Douglas fir stand
TL;DR: In this paper, the hydrology of the forest floor within a homogeneous Douglas fir forest was investigated and the authors used simple linear relations to translate forest floor water content dynamics from one site in a forest to another.
