Options

Basic option allows users to run every tool for watershed delineation automatically at once. Advanced option allows users to run any specified tools with customized inputs. Watershed Extraction option outputs entire watershed as a polygon shapefile by running only necessary steps - 'Move Outlets' and 'Gage Watershed'.
Basic Advanced Watershed Extraction
Select folder (optional) :

Automatic

This tool runs every step in the advanced option automatically. The outlet points will be moved to modified Peuker Douglas stream pixels. 10 pixels will be used as a stream threshold if drop analysis can't find the optimal value. The input DEM should be in a projected coordinate system with the same units of X, Y, and height. Otherwise, the slope raster's unit should be interpreted as [unit of height] / [unit of X and Y].

Watershed Extraction

This tool creates the entire watershed shapefile for the moved outlet points. Once user uploads or define outlet points, they will be moved to stream pixels automatically. The NHD+ v2.0 HydroDEM (stream-burned) pixels of values less than -100m were determined as stream pixels.

Clip DEM (optional)

This tool clips out NHD+ v2.0 DEM for input DEM (Note: This DEM is not burned DEM). Please drag mouse to the extent less than HUC 10 because clipping size is limited.

Fill Sinks

This tool fills out pits of input DEM to make input DEM hydrologically reasonable. The input DEM should be in a projected coordinate system. Later 'Stream Network - Drop Analysis' and 'Stream Raster - Threshold' tools accept only rasters in a projected coordinate system.

Compute Flow Direction

This tool creates two output grids - flow direction raster and slope raster, both in eight directions. The input DEM should be in a projected coordinate system. If input DEM is not in a projected coordinate system, the slope raster's unit should be interpreted as [unit of height] / [unit of X and Y].

Compute Flow Accumulation

Flow accumulation is calculated by summing up contributing numbers of pixels, through which stream flows into the target pixel. Please choose eight direction - flow direction raster as an input file.

Grid Analysis

This tool gives three outputs such as the longest flow path, total length of flow path, and Strahler Grid Network order.

Stream Network - Modified Peuker Douglas

This tool delineates stream pixes by the Modified Peuker Douglas Tool, which uses flow accumulation pixels in addition to original Peuker Douglas pixels.

Move Outlets

This tool moves user-uploaded or user-defined outlet points to stream pixels. Please upload outlet points shapefile by right clicking on folders or Spatial Layers in Project Layers section. Or click 'Create Layer' button and add outlets on the map. If you choose to upload shapefile, please upload files with formats - .shp, .shx and .dbf.

Weighted Flow Accumulation Area

Weighted flow accumulation sums up the number of contributing stream (such as Peuker Douglas) pixels at target pixel. The stream should eventually flow to the outlets.

Stream Network - Drop Analysis

Drop analysis finds the threshold value for stream raster by T test, which evaluates the significant difference between the average drops of the first and higher order streams created based on the threshold assumption. (Note: The input DEM should be in a projected coordinate system.)

Stream Raster - Threshold

Stream Raster - Threshold tool defines stream raster by choosing pixels from weighted flow accumulation grid with the values larger than the given threshold.

      In an effort to provide the most up to date and comprehensive data regarding draining mines throughout the state, the Division of Reclamation Mining and Safety (DRMS) and Colorado Department of Public Health and Environment (CDPHE) partnered to survey and sample 148 abandoned mines in 2016. The effort was championed by Governor Hickenlooper in his 2016 State of the State address. These 148 mines were a subset of roughly 230 mines DRMS, in cooperation with other state and federal agencies, identified as potentially impacting water quality. These mines were classified into three categories:

      • Green - Draining mines with partial to complete restoration (44)
      • Yellow - Draining mines with recent investigation or restoration project in process (32)
      • Red - Draining mines without recent investigations or restoration project (148)

      This website presents the results of the Abandoned Mine Water Quality Study. Red locations were visited and have water quality data, photos and complete field survey forms, unless those mines were not discharging water at the time of visitation. Yellow and Green locations provide mine name and locational information.

      The "Information" tab provides an executive summary and a downloadable dataset.

      Getting Started:

      1. Click "Abandoned Mines Information"
      2. Select layers to view on the map
      3. Use the Info Icon tool to select and summarize layer attributes
        • Only visible layers will be queried
        • If multiple layers are visible, use the drop down menu, at the top of the info box, to select which layer attribute summary to view
      4. Information about the datasets and other metadata is available on the "Information" tab
      5. Other Map Tools:
        • The Pan Icon tool to allows you to pan/move on the map
        • The Zoom Icon tool to allows you to zoom to a selected area on the map
        • The Zoom-Previous Icon tool to allows you to zoom to the previous zoom extent
        • The Zoom-Next Icon tool to allows you to zoom to the next zoon extent (only available after using the zoom to previous extent)
        • The Zoom-Extent Icon tool to allows you to zoom to the extent of all project layers
        • The Clear Icon tool to allows you to clear your query selection from the map
        • The Layout Icon tool to allows you to print the current map extent
      6. Map Base Layer:
        • A number of base layers (map background) images are availble in this tool. To switch to a different base layer (i.e. satellite aeral view):
          1. On the 'Map' tab, click on 'Base Layers'
          2. Select which base layer to use (i.e. Google -> Satellite)
      7. Public Layers:
        • If an item is struck out with a line, it is not visible at the current scale. Zooming in will activate this layer.
        • To access additional information on the Public Layers, left-click on the individual layers. This will bring up a list of options:
          1. Zoom to Full Extent - Zooms to the full extent of the data
          2. Zoom to Visible Extent - Zooms to visible extent of the data
          3. Transparency/DPI - The transparency slider changes the transparency of the layer. The DPI slider will change the size of the points.
          4. Identify Features - When selected, this activates an information tool. Draw a box around the feature to show more information about it.
          5. Map Service Metadata - Information about the data.
          6. Extract Layer - This is used to extract information from the Public Layers into the main project "Abandoned Mines Information" list of layers. From the drop down, the user can select the layer or "new layer" to place this information into. To choose the data points/features, choose the method (e.g. polygon, rectangle, etc.) you would like to use to choose the points/features on the map. Choose the features on the map using the selected tool and click the "Generate" button. This will extract the selected data as a layer into the "Abandoned Mines Information" section.
