Welcome to QTalsim’s documentation!

QTalsim is a QGIS plugin with five principal functionalities that enable the processing of spatial data suitable for Talsim. The core functionality of this plugin is to calculate Hydrological Response Units (HRUs) suitable for Talsim. This feature requires three input layers, that can also be created by the plugin. Further more, it is possible to connect to a Talsim database and to edit elements.

Main Features

• HRU Calculation

  Enables users to calculate Hydrological Response Units (HRUs).

• Sub-basins Preprocessing

  Calculates various parameters for each sub-basin and generates files compatible with Talsim.

• ISRIC Soil Type Converter

  Downloads and processes data from ISRIC, creating a soil layer that includes soil type and bulk density.

• Land Use Mapping

  If your area is in Germany, this feature allows you to convert ATKIS land use data into Talsim land use categories.

• Connect to Talsim DB

  For users of Talsim NG5, this functionality enables a direct connection to a Talsim database, allowing you to edit system elements, sub-basins, and transport reaches.
