For the past two years, NMRWA has been working with the Pittsburgh Parks Conservancy (PPC) to increase the environmental stewardship capacity of ourÂ watershed community. Funding for this work was provided by a grant received from the National Fish and Wildlife Foundation’s Five Star and Urban Waters Restoration Program. Maybe you read about this in our Doxycycline online pharmacy usa?
Yesterday, as a part this program,Â NMRWA staff co-led a training workshop for Urban EcoStewards on streamflow monitoring in Nine Mile Run. Along with Sarah Lavin, a graduate student in the Nizagara canadian pharmacy, Sara Powell & Paul Yanulavich spent aÂ sunny Sunday morning working with eight volunteers to measure streamflow and take cross-section measurements of the stream.
It is important for us to understand streamflow patterns and how the stream channel is changingÂ in Nine Mile Run, both for continued restoration efforts in Frick Park (e.g., erosion remediation), and also so we can assess how well management efforts in the upper watershed (e.g., green stormwater infrastructure, rain barrels) are reducing excess stormwater flows into the stream.
Unfortunately, continuous monitoring of discharge (the volume of water flowing through the stream during a unit of time)Â is complex and expensive. Instead, since last summer, we have been working with Stiemycin solution buy online (UES) volunteers to help us collect data that will allow us to create something called a stage-discharge rating curve.
This curve will allow us to ‘reconstruct’ a continuous discharge record – giving us a much better understanding of streamflow in Nine Mile Run!
So, at Sunday’s training, we demonstrated how UES volunteers can measure the stream’s velocity and cross-sectional area – two critical pieces to calculating discharge. We then used similar methods to measure the stream channel geometry.
The geometry of the channel is also important to understand, because storms can cause large volumes of water to surge rapidly through Nine Mile Run, changing the stream channel shape very quickly. These changes, whether they areÂ due to erosion or damage to built rockÂ features, put our restoration efforts at risk.Â Regular cross-section measurements will allow us to look at how the shape of the stream channel is changing over time, and to apply necessary management efforts as needed.
Thank you so much to all the Urban EcoStewards and interested volunteers for coming out on Sunday! We will be posting more photos from the day on our Facebook page, so make sure to check them out!
