We use a pour-point model to show how and in which direction water travels. The eight adjacent cells in the pour point model have a value expressing how water drops. Flow Direction Example When water flows in the east direction, it has a value of 1. When water flows west, it has a ...
TheFlowMapper pluginfor QGIS is a quick and easy way to generate flow maps of your own. When you download the plugin, it comes with test data that you can use as a template. But essentially, it boils down to these two text files as inputs: A list of nodes with theirlatitude and lo...
Wavy flow; occurs at greater gas velocities and has waves moving in the flow direction. When wave crests are sufficiently high to bridge the pipe, they form frothy slugs that move at much greater than the average liquid velocity. • Slug flow; may cause severe and/or dangerous vibrations ...
We estimated the rate and direction of recent gene flow using BayesAss 3.0.459. This program calculates migration rates (hereafter referred to as dispersal rates) over the last few generations and does not assume HWE or mutation-drift equilibrium59. We estimated dispersal rates (i) for all samp...
across the nuclear genome we found a strong signal in the opposite direction, with 30% excess allele sharing between Malawi catchmentA. callipteraand mbuna (Fig.4d). Therefore, the Joyce et al.20hypothesis that the mbuna, the most species-rich group within the radiation, may be a hybrid ...
They were incorporated into the QGIS program, and using the tools provided by LAStools, the point layer was converted into a digital model of the terrain. This was conducted layer by layer for the area of study, and a digital model of the terrain was created based on the points with ...

This combined approach, facilitated by the MOLUSCE plugin within QGIS, enables the generation of predictive scenarios for future LULC patterns, providing valuable insights into potential landscape transformations. For this study, the LULC variations are considered for predicting the future streamflow of ...
A watershed, where precipitation collects and drains off into a common outlet, is a hydrological unit commonly used in natural resource management and planning [43]. Now, most GIS software can be used to extract watershed data, such as ArcGIS, QGIS, SAGA and so on [44,45,46]. These tool...
