Integrated Tool for Morphometric Analysis Using QGIS

Measurements of drainage basins and its parameters were evaluated earlier using conventional methods. At present, Geographic Information System (GIS) technique along with Remote Sensing data offers a better and precise way in performing morphometric analysis. Morphometric analysis of a watershed provides a quantitative description of a drainage system. It is an important aspect of the watershed characterization. As the analysis is having many parameters (drainage, slope, aspect, hillshade, watershed delineation, stream order, length of drainage channels, catchment area and perimeter, drainage density, form factor etc.) it requires different sequential operation to get all those results. When it come on handling numerous and big data set it tends to be tedious and time consuming and to overcome that some effort is to be made. In this study the main emphasis is given in developing an automatic integrated tool in GIS environment which helps in proper data handling results in reducing the time and workload of both user and the workstation. The Digital Elevation Model (DEM) of Asan river catchment is taken as the main input for the model and analysis is performed on it which exhibits suitable and accurate result and can be further utilize in watershed management.
