ImageryViGrA [deprecated]ViGrA - "Vision with Generic Algorithms" Version: 1.11.1 ViGrA is a novel computer vision library that puts its main emphasize on customizable algorithms and data structures. By using template techniques similar to those in the C++ Standard Template Library (STL), you can easily adapt any ViGrA component to the needs of your application, without thereby giving up execution speed. Find out more at the ViGrA - Homepage.
Because the ViGrA project seems to be abandoned since quite a while SAGA's ViGrA tool set has been marked as deprecated and might become removed from future SAGA versions!

SimulationHydrology: IHACRESThe metric conceptual rainfall-runoff model IHACRES (Identification of unit Hydrographs and Component flows from Rainfall, Evaporation and Streamflow data) has been implemented as a module library. The IHACRES model was developed by: Jakeman, A.J. and G.M. Hornberger (1993); Jakeman et al. (1990). Purpose The tool can be used to simulate streamflow (catchment runoff) on the basis of daily rainfall and temperature data. No spatial data, such as elevation models, soil or land use maps are required. IHACRES has been applied to catchments with a wide range of climatologies and sizes (Croke et al., 2004). It has been used to predict streamflow in ungauged catchments (Kokkonen et al., 2003; Post and Jakeman, 1999; Post et al., 1998), to study land cover effects on hydrologic processes (Croke et al., 2004; Kokkonen and Jakeman, 2002), and to investigate dynamic response characteristics and physical catchment descriptors (Kokkonen et al., 2003; Sefton and Howarth, 1998). More recently, the model has been used to develop a rainfall-runoff database for flood risk assessment and forecasting by Liersch, S. and M. Volk (2008) (pdf). References

Tool ChainsTravel Time Analysis The travel time tools were created to join together and automate a number of processing steps in order to simplify service access modelling. The purpose of these tools is to create a simple open source way of calculating travel time to services to facilitate rapid testing of multiple travel scenarios. Two tools have been created using SAGA GIS Tool Chains. The SAGA Tool Chains capability uses a simple xml scripting code that allows the joining of multiple SAGA processes. The two tools produced are (1) for land cover grid creation and (2) travel time calculation, the latter requiring the output of the first. Separating the two tools allows for simpler and faster execution to test multiple scenarios with the Travel Time Grid creation tool without having to recalculate the base land cover grid each analysis iteration. Find further information at Rohan Fisher's web page on Travel Time Modelling with SAGA. 2
