How to use the central BMP.

The use of a central BMP allows for the user to load all upstream subcatchments to one downstream subcatchment. To include this option the user should check the "Add Central BMP" checkbox within the "Edit Catchments and BMP" tab. A new section appears for the user to edit the central BMP characteristics. First, the user must select which subcatchments in the list will be routed to the central BMP. Then, click the "Edit Central BMP" button. The form that appears allows the user to choose the central BMP type and define the specific characteristics similar to those available in the subcatchment editor form. The user may choose from 4 types. The maximum pond volume and contributing area are internally calculated by SELECT based on the upstream subcatchment characteristics routed to the central BMP. Add any addtional information desired, such as the percent losses, BMP surface area, dead volume, settling velocity, and cost values. Once finished, the user should select "Ok" to exit out of the form.

If you have an appropriate (.wmv) plugin installed, you can view a tutorial on using the central BMP here.  Alternatively, a downloadable version (.avi) can be found here. (Note that download can take several minutes and that you'll need a viewer like Real Player or Microsoft's Media Viewer to see the tutorial.)

How to update watershed parameters.

The 'Set Default Values' form contains four tabs that allow you to edit parameters for the Watershed, BMPs, and the rainfall data or allow data to be downloaded from a database. Within each tab are options for creating new, updating or deleting data. The Watershed Parameters tab has three default watershed land use types listed. The user may select any of these to update the default values or create a new land use type to better represent the watershed characteristics. For example, the default values for the residential watershed type include percent impervious and depression storage values that more than likely will need to be updated to more accurately represent the watershed characteristics being analyzed. The runoff coefficient may be calculated using the percent impervious by clicking the 'Calculate' button. There are also input boxes for mean and standard deviation data for phosphorus, nitrogen, suspended solids, fecal coliforms, copper and zinc. The user may decide whether or not the default values are sufficient for the watershed being analyzed. Once all data has been update, the user should select 'Save' to exit out of the form and return to the 'Watershed Parameters' tab.

How to download rainfall data from NCDC site.

Data may be downloaded from the National Climatic Data Center Website at www.ncdc.noaa.gov. Click on the landbased station data link within the lefthand side menu. Within the submenu select "Find a Station". Here you have two options: search by using the station name or using an interactive map tool. For this tutorial the interactive map tool is highlighted. Click on the map image to open the map tool. The map tool is built of layers of precipitation data. On the right hand side of the map, select the hourly data layer and uncheck any other layers that are not necessary. Doing so will improve the performance of the map. A dropdown menu on the left side of the map allows the user to choose between layers in order to utilize a variety of selection tools. Select the hourly precipitation layer. Navigate to the general area of interest on the map using the zoom tools on the left side of screen. The site provides a number of ways to acquire data from the gaging stations within the floating toolbar. Select a tool then highlight the desired gages. A list of gages appears. After reviewing the data available, check the box next to the desired gage. Click on the "Get Selected Data" button on the bottom left side of the window. The website asks for an email address, the desired time range of data, and the output format on the right side of the screen. The delivery format selected should be the text option (NOT the CSV option). The next page presents the data types available for the selected station and allows the user to select additional output options. Skip selection of the additional output options and proceed directly to the "Continue" button. The final page provides an order confirmation number and a summary of requested data. Processing of the data may take up to a few minutes. In your email, you should see two emails from NCDC: one verifying they received your order request and the other telling you the processing of your order is complete. The second email provides a link to the data. Open the email to retrieve teh data. Highlight and copy the data and paste it into a text editor. Save the file. This text file can be used directly in SELECT by using one of the two import rainfall options.
