    Format of GSSHA.dep file

    Hello, I'm assuming that *.dep file the is the data file of simulated water depths for a given GSSHA simulation. I'd like to be able to import this file into Python or R to automate evaluation of simulated water depths at various locations within a model domain. Also, what is the general structure of the .dep file, and how is this linked to the model domain? Is the linkage through cell index or through the coordinates of the cell centroids? Thanks, David

    Converting GIS Point Features Into Gaging Stations

    Hi Chris, Sorry for the repeated posts. I wrote a small Python script to transform the point feature data into the gage file format you gave. It worked quite well. Thank you.

    Converting GIS Point Features Into Gaging Stations

    Hi Chris, An additional question: the gage file format looks to be space delimited. Is this correct? Thanks again, David

    Converting GIS Point Features Into Gaging Stations

    Hi Chris, As always, thank you for looking into this. I'll try your suggestion and let you know if it works. Perhaps this would be a good feature to add to WMS. Also, is there a way in WMS to do a bulk extraction of time-series from multiple gages? For example, one (ideal) export structure would be gages organized by ID (as columns) with a common time-stamp. Thanks again, David
  5. Hello, I'm trying to retrieve dynamic stage in a number of depressional features within a model. Is there a way to convert points within a shapefile into monitoring gages within WMS? Thanks in advance. David

    Extracting Flow Depth Time-series

    Hi Cody, Thank you for the suggestion. I'll take a look at placing monitoring gages in the depressions to get time-series of depth accumulation. The second part of my question is a bit vague, and is really mainly an idea at this point. In depressional landscapes depressions become connected through a fill-spill mechanism. This results in a continuous water surface connecting some depressions, but not all. The only way I can think of to map the connectivity of depressions at various points in a simulation is to evaluate the water depth contours and whether they intersect depressions. Is there a way to export these for a model domain for a set of time-steps? Thank you for your help. David

    Extracting Flow Depth Time-series

    Hello, I'm currently using GSSHA to model overland flow processes in a depression-dominated watershed. I've successfully mapped and retained the depressional characteristics of this basin, and have retained these features in the model and subsequent simulations. Now, I'd like to be able to determine the rate at which depressions fill from overland flow, and determine the extent of surface water connectivity between depressions using water depth contours at various times during a simulation. Is this possible using built-in WMS tools? Thanks, David

    Depression Polygon Mask

    Hi Chris, Thank you for the prompt reply and detailed instructions. I've worked through most of the tutorials on WMS, but have yet to fully make connections between parts of the platform. As I mentioned in my post, we are modeling depressional storage and fill-spill processes on varied low-relief watersheds (i.e. think the prairie pothole region). I know that these depressions exist on the landscape, but am uncertain about whether they are retained in WMS when building a GSSHA model. For instance, are all depressions resolved when running TOPAZ?, and if so, does the elimination of these features show up in the model grid? How can I be certain that I am retaining depressional features on the landscape, and ensuring that GSSHA models their fill-spill processes correctly? Thanks in advance for your assistance. David

    Depression Polygon Mask

    Hello, I'm attempting to construct a GSSHA model of a low-relief watershed containing a significant number of natural topographic depressions. I'm uncertain about how to build and apply the depression polygon mask within WMS. I have a polygon shapefile of the depressions for this watershed. Can someone either point me in the direction of a tutorial on this process, or provide general steps within the answer to this post? Thanks, David
