[1] Dekker and Rietkerk [2005] (hereinafter referred to as DR) raise some valid points regarding our paper ‘‘Multiple equilibrium states and the abrupt transitions in a dynamical system of soil water interacting with vegetation’’ [Zeng et al., 2004] (hereinafter referred to as XZ). We appreciate the opportunity to clarify these issues here and hope this dialogue (between scientists working on h...

We developed and evaluated a three-layer snow model for application in general circulation models. This onedimensional snow model has many features of the detailed physically based model SNTHERM, yet is computationally much simpler. We have also extended the point model to vegetated areas using the parameterization concepts of the Biosphere-Atmosphere Transfer Scheme (BATS). Results of model ap...

In semi-arid regions, infiltration of rain water into the soil is significantly higher in vegetated areas than for bare ground. However, quantitative data on the dependence of infiltration capacity on plant biomass is very limited. In this paper, we use a simple reaction-diffusion-advection model to investigate the effects of varying the strength of this dependence. We begin by studying the for...

A Compact Airborne Spectrographic Imager-2 (CASI) dataset was used for detecting mortality and vegetation stress associated with a new forest disease. We first developed a multilevel classification scheme to improve classification accuracy. Then, the CASI raw data were transformed to reflectance and corrected for topography, and a principal component (PC) transformation of all 48 bands and the ...

Theoretical considerations and empirical evidence indicate a linear relationship between the land surface temperature (Ts) and the corresponding evapotranspiration (ET) rate under spatially constant wind and net energy conditions at a homogeneous vegetated surface. Such a relationship lies at the core of the popular surface energy balance algorithm (SEBAL); the satellite-based energy balance ap...

—Lampropeltis getula is a species of conservation concern in several parts of its wide geographic range. I describe habitat use and movement patterns of L. getula holbrooki in an agricultural landscape, a portion of which has been brought out of agriculture and reforested. Both sexes strongly preferred vegetated shrubby levee habitats, and avoided active agricultural fields. There was no eviden...

The researcher will be required to work on vegetation monitoring using hyperspectral airborne or space borne data in both mountainous and urban areas. The research will require the definition and the implementation of a full processing chain of hyperspectral datasets that is able to start with radiometrically calibrated data and ending with maps of vegetated species and tree status in various e...

River flooding is one of the most widespread natural disasters. Projections indicate that climate change will increase flood hazard in many areas around world. In this study, we investigate individual and combined effects sea level rise, flow riparian vegetation encroachment on lower Biobío River, Chile. Results show each has potential to individually certain areas, can compound. Encroachment o...
