Specialized in hydrology, geomorphology and hydraulics, she developed and applies environmental models for engineering projects in particular related to the natural hazards and the maintenance of
The HortonMachine library is a Free and Open Source geospatial library containing tools for data management (raster, vector and point cloud), data collection in the field, and environmental modelling. The environmental models are mainly related to hillslope stability, floods, debris flow and woody (Large Wood) floods.
The HortonMachine is actually a suite of independent tools, a package of applications (i.e. SpatialToolbox, DBViewer, GForm) without a specific GIS support. The input and output geospatial data follows the main OGS standards and can be visualized within anyone’s preferred GIS.
In the last year a set of modules of the SpatialToolbox have been developed to perform geomorphological analysis to automatically delineate a hierarchical structure of basins and subbasins for a selected area. The result of the analysis will be the input of the integral distributed hydrological model GEOframe. The GEOframe application is a complex system with more than 50 components used to simulate the complete hydrological cycle within a watershed (Spatial extrapolation/interpolation of meteorological variables; Estimation of the radiation budget, evapotranspiration, runoff production; Simulation of infiltration; Calibration).
The first tool is an improvement of the original NetNumbering algorithm with a new feature to homogenize the area of the extracted basins and, at the same time, it saves the hierarchical structure of the basins which can be used to navigate the network upstream and downstream. Based on the output of this model the new GeoFrameInputBuilder tool creates the complete input folder of the geomorphological inputs of the GEOframe model.
