The ability to predict how water will behave when filling a reservoir is essential for planning and managing water resources. For those interested in civil engineering, hydrology, and risk management, … Read more
A watershed is an area of land that captures water, which eventually flows through a single point or outlet such as rivers, reservoirs, and the ocean. QGIS 3 has a … Read more
Endorheic basins (internally drained) have no surface outlet (to a river) and lose water through evaporation and sometimes underground. In the traditional method of watershed delimitation, these internal drainage areas … Read more
Spatial Analyst and Hydrology tools can be used to identify and extract dividing lines (of mountains) from an elevation raster (DEM), this by creating a network of flows by inverting … Read more
Very often catchment delineations are required for several processes in hydrological analysis. The GIS offers a lot of flexible tools in order to derive these products, using as main input … Read more
The information which can be derived from Elevation data have a lot of applications in different fields of the science, from hydrology, risk analysis, urban planning among others. In this … Read more
Fundamentals of Remote Sensing Tutorial, is available for free by The Canada Centre for Mapping and Earth Observation (formerly Canada Centre for Remote Sensing). The tutorial is structured as a … Read more
One of the most used geomorphic parameters (both directly or to derive other parameters) is the river profile. Sometimes the estimation of this parameter can be cumbersome to some users … Read more
