arcgis groundwater flow direction

In the following image, the flow direction of the groundwater is determined using the Darcy Flow and Darcy Velocity tools to understand how a contaminant will move through the groundwater. Particle Track Calculates the path of a particle through a velocity field, returning an ASCII file of particle tracking data and, optionally, a coverage of track information. Again, thanks for the reply. This example calculates the groundwater volume balance raster as well as the flow direction and seepage velocity of an aquifer. The differences between Darcy Flow and Darcy Velocity are:. Usage. Please let me know if you can think of anything other tool to use. Click OK. Is there an email I could reach you at that might be able to allow better communication? Piezometric Map. Thanks for any help! The previous image was using elevational values that were based off a benchmark of 10m, so values were between 9-7 meters but not true to mean sea level. Thanks, Noman With Groundwater Analyst you will be able to import a variety of datasets (wells, time series, cross sections, volumes) into your geodatabase, manage symbology of layers in ArcMap and ArcScene, map and plot time series, and create common products such as water level, water quality, and flow direction maps. A complete professional GIS. Use the DEM output from Step 1 as the 'Input surface raster'. Sorry to have to ask you for more advice but I am at a loss and so frustrated. ArcGIS for Developers. These lines were created using my research data of hydraulic head values and elevation of the groundwater system. thematic layers were finally integrated using ArcGIS and IDRIS software to produce a g roundwater potential . Its still the same field site just actual values. I guess I am not sure which interpolation you are suggestion since both have flaws. So the direction of groundwater flow is usually two directions, losing stream or gaining stream for floodplains. Navigate to Spatial Analyst Tools > Hydrology > Flow Direction. I am looking at the groundwater surfacewater relationship between stream and floodplain groundwater. Working with Borehole Data: Creating GeoRasters from Borehole Data: Updating GeoRasters Using Cross Section Data: Building 3D Models with the Horizons Method: Working with Non-Vertical Borehole Data: Well Construction: Those are D8, Multi Flow Direction (MFD) and D-Infinity (DINF). Utilities Style - Marker Symbols R amfm water 08 N amfm water 09 O amfm water 10 Can you please help me if you find the correct way?? I want to create. I am constantly working on trying to fix problems with it. In ArcCatalog, navigate to Toolboxes > System Toolboxes > Spatial Analyst Tools > Hydrology > Flow Direction. Comunidad Esri Colombia - Ecuador - Panamá. Any other suggestions you might have now with the new version is welcomed. I guess the main problem I would like to try and have fix is using an analysis that would not start at points of origin and would look at the site as a whole. You are correct on that the hand version has flaws. You are correct that these maps were created based of piezometer head readings. Flow lines serve two purposes. 3.5. I am looking at the groundwater surfacewater relationship between stream and floodplain groundwater. Below you will see the new version. The first shows what I think should be the groundwater flow lines based off the equipotential lines that were created in ArcGIS using contours. If this tool works for me, that would make a world of difference! The values for each direction from the center are the following: For example, if the direction of steepest drop was to the left of the current processing cell, its flow direction would be coded as 16.
