Digital terrain modelling: A review of hydrological, geomorphological, and biological applications
The topography of a catchment has a major impact on the hydrological, geomorphological. and biological processes active in the landscape. The spatial distribution of topographic attributes can oftenExpand
Observed spatial organization of soil moisture and its relation to terrain indices
We analyze the degree of spatial organization of soil moisture and the ability of terrain attributes to predict that organization. By organization we mean systematic spatial variation or consistentExpand
Preferred states in spatial soil moisture patterns: Local and nonlocal controls
In this paper we develop a conceptual and observational case in which soil water patterns in temperate regions of Australia switch between two preferred states. The wet state is dominated by lateralExpand
Towards areal estimation of soil water content from point measurements: time and space stability of mean response
Areal estimates of soil moisture over large areas are required for the ground truthing of remotely sensed measurements and for establishing catchment-wide antecedent conditions for runoffExpand
Spatial correlation of soil moisture in small catchments and its relationship to dominant spatial hydrological processes
The geostatistical properties of soil moisture patterns from five different sites in Australia (Tarrawarra and Point Nepean) and New Zealand (three sites from the Mahurangi River Basin—Carran’s,Expand
Scaling of Soil Moisture: A Hydrologic Perspective
▪ Abstract Soil moisture is spatially and temporally highly variable, and it influences a range of environmental processes in a nonlinear manner. This leads to scale effects that need to beExpand
A quasi-dynamic wetness index for characterizing the spatial distribution of zones of surface saturation and
A quasi-dynamic wetness index that accounts for variable drainage times since a prior rainfall event is derived from simple subsurface flow theory. The method is tested through a series of fieldExpand
Physically based hydrologic modeling: 1. A terrain‐based model for investigative purposes
THALES, a simple distributed parameter hydrologic model is presented and applied to two catchments in Australia and the United States, each with different dominant hydrologic responses. The modelExpand
Determining the sources of suspended sediment in a forested catchment in southeastern Australia
[1] Knowledge is scarce regarding the relative contributions from harvested areas and unsealed roads to sediments in forested catchments. We investigate the source composition of suspended sedimentExpand
The Tarrawarra data set: Soil moisture patterns, soil characteristics, and hydrological flux measurements
Experiments investigating the spatial variability of soil moisture conducted in the 10.5 ha Tarrawarra catchment, southeastern Australia, are described. The resulting data include high-resolutionExpand
