The aim of this paper is to present a new GRASS GIS toolset designed for Hortonian
analysis of drainage networks. The r. stream toolset uses a multiple flow direction algorithm …

A statistical approach to LiDAR derived topographic attributes for the automatic extraction of
channel network and for the choice of the scale to apply for parameter evaluation is …

Hydraulic conductivity K, as the coefficient of proportionality in Darcy's Law, is critical in
understanding the past Martian hydrologic cycle, climate, and landform evolution. However …

A spatial stochastic algorithm that aims to reconstruct an entire artificial drainage network of
a cultivated landscape from disconnected reaches of the network is proposed here. This …

River networks are often derived from digital terrain models and are affected by uncertainty
and errors of the corresponding elevation data. The analysis of the spatial distribution of the …

En zone méditerranéenne, d'intenses précipitations automnales sont responsables de crues
particulièrement violentes: les crues «éclair». L'intensité et la variabilité des précipitations …

Many digital elevation models (DEMs) have difficulty replicating hydrological patterns in
depressions and flat areas. Thus, methods of DEM hydrological correction must be used …

More and more elevation data and methods are available to automatically map
hydrographic or thalweg networks. However, there are few methods to assess the network …

Depression filling and direction assignment over flat areas are critical issues in hydrologic
analysis. This paper proposes a method to handle depressions and flat areas in one …
