Purpose
The purpose of this Wiki tutorial is to demonstrate and explore various hydrology tools used for hydrological analyses in QGIS. The objective of this tutorial is to provide instructions on how to use digital elevation models (DEM) for extracting channel networks, delineating watersheds and defining a catchment area. Additionally, this tutorial will allow for comparison between open source softwares of QGIS, ILWIS and SAGA GIS, tutorials created for hydrological analyses in 2013 and 2014.
Introduction
Hydrological analysis tools are important resources and are used in a variety of programs to define how the geographic range of an area interacts with water. Hydrological analyses can aid researchers and emergency personal in identifying the source and pathway of groundwater, delineating watersheds and identifying communities prone to flooding conditions (Sui et. al., 2011, Mani et al., 2014). A variety of programs can be used to perform hydrological analyses including ARCGIS, ILWIS and SAGA GIS. This tutorial will give instructions on using QGIS, a Free and Open Source Software for Geospatial Data (FOSS4G), for hydrogeological analyses. QGIS is an open source geographic information system that runs on various platforms including Windows, Mac OS and Linux (QGIS, 2015). Using a digital elevation modeling of the West Ottawa region, we will demonstrate and explore hydrogeology toolsets offered by QGIS.
