In this article, a system which determines slope, aspect, and curvature in both the downslope and across-slope directions is developed for an altitude matrix, and the upslope drainage area and maximum drainage distance are determined for every point within the altitude matrix.
Abstract
Land surface topography significantly affects the processes of runoff and erosion. A system which determines slope, aspect, and curvature in both the down-slope and across-slope directions is developed for an altitude matrix. Also, the upslope drainage area and maximum drainage distance are determined for every point within the altitude matrix. A FORTRAN 66 program performs the analysis.

Digital terrain modelling: A review of hydrological, geomorphological, and biological applications

TL;DR: In this article, the authors describe elevation data sources, digital elevation model structures, and the analysis of digital elevation data for hydrological, geomorphological, and biological applications.

On digital soil mapping

TL;DR: The generic framework, which the authors call the scorpanSSPFe (soil spatial prediction function with spatially autocorrelated errors) method, is particularly relevant for those places where soil resource information is limited.

Landslide inventory maps: New tools for an old problem

TL;DR: In this article, the authors outline the principles for landslide mapping, and review the conventional methods for the preparation of landslide maps, including geomorphological, event, seasonal, and multi-temporal inventories.

A detachment-limited model of drainage basin evolution

TL;DR: In this article, a drainage basin simulation model incorporating creep and threshold slumping and both detachment-and transport-limited fluvial processes is introduced, and it is argued that fluvial erosion of natural slopes and headwater channels is dominantly detachment-limited.

Predictive vegetation mapping: geographic modelling of biospatial patterns in relation to environmental gradients:

TL;DR: Predictive vegetation mapping as discussed by the authors is defined as predicting the geographic distribution of the vegetation composition across a landscape from mapped environmental variables, which is made possible by the availability of digital maps of topography and other environmental variables such as soils, geology and climate variables.

Topographic controls of soil moisture distributions

TL;DR: In this article, the potential value of topographic indices as a basis for the prediction of soil moisture distributions and hillslope runoff is briefly discussed, but only at times of high soil wetness.

Saturation regions in catchments and their relations to soil and topographic properties

TL;DR: In this paper, the authors derived criteria for the existence of saturated areas on draining hillslopes in natural catchments in terms of soil transmissivity, the hillslope gradient and its wetness state, characterised by the baseflow discharge from the catchment.

One-Sided Constraints in Automated Contouring of Drift Thickness

TL;DR: In this article, a technique is described which permits the use of minimal and maximal data values in automating contouring of drift thickness from shallow borehole data and the facilities available and the strengths and weaknesses of the method are described in relation to the contouring.
