Résumé partiel
In case of the semi arid agro climatic conditions, there is need to enhance the land and water productivity sustaining spatially and temporally distributed rainfall quantity and its erosive effects. The primary objective of the work was to develop a spatial decision support system for optimal hydrological planning of land and water resources relating the variable characteristics of land use, soil and rainfall. The conceptual decision and flow logic was formulated to link this information through MMF model and transformed into computer model using python programming language. The QSCOT was developed with PyQt graphical user interface (GUI) capability and integrated with QGIS which is open source software and available for all users across the world as “QGIS plugin” repository. It provided the user with an effective interactive environment to select or enter the input variables and to get output data on runoff and soil loss rate at any stream node. Moreover, SDSS-QSCOT contains many features including “suggesting suitable soil conservation and water harvesting measures for arable and non arable lands”, “estimating excess runoff”, “displaying conservation measures spatially with set of icons as a vector layer”, which would enhance its efficacy in effective-interactive communication method for better comprehension
