CUENCAS is a river networks analysis tool. It is a simplified version of the original GIS called HidroSig, developed by the Water Resources Department at the Universidad Nacional de Colombia over the last 5 years.
In addition to being a DEMs analysis tool, CUENCAS, establishes a Data Organization Framework (DOF), that allows different modules to interact with spatially and/or temporarly concurrent data. The DOF is illustrated in greater detail here.
The group of tools currently built into Cuencas can be group as:
River Network Extraction from Digital Elevation Models (DEMs) River Network Geomorphologic Analysis including but not limited to: Topologic and Geometric Width Function Horton Analysis Generalized Horton Analysis (Simple scaling of network properties) Network links analysis (Length, area, slope, etc) including xy-plots for link properties (e.g. Hack's Law) Area-Altitude Self-similarity based on the Random Self Similar network (RSN) model. Scale analysis of spatially distributed variables (Precipitation, Evaporation) in the river network context. Link based rainfall-runoff model 3D view of the basin Decomposition of basin into links and hillslopes Real time flow simulations Water Balance
Visualization tools for DEMs Visualization and Animation tools for Spatial Fields (e.g. precipitation) Time Series Analysis Rainfall Fields Simulator
