It also assigns the necessary subbasin identification. The delineated watershed with subbasins will be added to the View. The procedure is similar to the process of manually adding or removing an outlet. The DEM properties should correctly define the grid size and units. If the wrong subbasin is arcswta, click No and repeat step 7 2.
If not, an error dialog will prompt. In this section, the method based threshold area will be introduced.
Using this button, the user can check the projection information of the DEM Figure 7. For simulation, a watershed is subdivided into a number of homogenous subbasins hydrologic response units or HRUs having unique soil, slope and land use properties. Add DEM Grid 1. Click beside Maskthen three options is available to specify the watershed area of interest: Choose Load from disk and tutorrial the DEM grid located in your disk and click add.

Inlets represent any point source loading into the study area or the inlets tjtorial drainage into the watershed from an upstream area. Assuming the outlet and stream definition to be acceptable proceed to inlet definition for the study area. If the wrong subbasin is listed, click No and repeat step 7 1. A stream network theme can be superimposed onto the DEM to define the location of the stream network.

In this step the users will select one or more outlet locations to define the boundary of the main watershed. Select the Load mask grid from disk option and click OK. A prompt box will appear to announce completion of the watershed and subbasin delineation. However the general procedure is given below for reference. How to Create a Project. The detailed procedures on how to use the Watershed Delineation tool are introduced in the following sections: Next step is Outlet and Inlet Definition.
Click EXIT in the watershed delineation main dialog. You can view the area and percentage wise distribution of tuhorial for the entire watershed and each subbasin. After loading DEMthe button will be activated.
In this example, select 1 outlet at the downstream edge of the masked area Figure 14 and click the Delineate Watershed button. Reservoirs The user can add or remove reservoirs to refine the delineation process. It means that a minimum number of cells are required to start delineating the stream. Go to the View menu of ArcMap, hover the mouse over the Toolbar button, a list of tools will appear.
This tool is used to create watershed delineations using a combination of DEM, digitized network, and other user inputs. If the correct subbasin is listed, click Yes. Open the Reach or Watershed attribute tables to view the calculated characteristics. Exit the Watershed Delineation Dialog. Click on the Calculate Subbasin Parameters button to estimate the subbasin parameters.
To add a reservoir, click on the ADD button and with the cross appearing as mouse pointer, click on the subbasin where the reservoir will be added.
Main Watershed Outlet s Selection and Definition. A dialog box with Select option from Select from Map and Load from disk is opened.
