The Model of Living Landscape (MLL) is a set of empirical based tools for land management and landscape planning. It recognizes the complexity of the interactions between humans and the natural environment, and it aims to create a sustainable and resilient landscape that supports the well-being of both people and nature. One of the core MLL components is a process-based model for rainfall-runoff and erosion computation called SMODERP. The model operates on the principle of cell-by-cell mass balance, calculated at each time step. SMODERP (https://github.com/storm-fsv-cvut/smoderp2d) is open-source software implemented in Python language to ensure compatibility with most GIS software solutions. The current implementation supports Esri ArcGIS, GRASS GIS and QGIS. In this contribution, a new QGIS SMODERP plugin linking the hydrologic model outputs to MLL will be presented. The plugin performs the input data preparation on the background using GRASS GIS data provider, computation is done by SMODERP Python package, and results visualised with predefined map symbology in QGIS map canvas.

Surface runoff is one of the processes with direct impact on water erosion. Surface runoff has two basic components: a) sheet runoff and b) rill runoff. Observation of these phenomena at various scales and then using mathematical models to describe their observations plays a key role for soil protection. One of the models developed to compute these phenomena is SMODERP, used for example in the flexible and adaptive approach to land management and landscape planning called Model of Living Landscape project. Innovative application of the SMODERP model (https://github.com/storm-fsv-cvut/smoderp2d) named SMODERP Line is presented in this contribution. SMODERP Line is accessible through various interfaces including OGC Web Processing Service (WPS) which can be easily integrated into user-defined processing pipelines or web applications. Usage of SMODERP2D Line will be demonstrated in the QGIS environment through a new OWSLib-based QGIS WPS Client Plugin (https://github.com/OpenGeoLabs/qgis-wps-plugin).
