For urban watersheds VELMA has been setup at 5m resolution and includes a developed urban coverage type. Also includes a stormwater system. Bob's presentation focused more on the large watersheds that will feed into the SSM 01:53:24 Alan Chapman: Will existing models project whether stream flow changes associated with climate change be mediated effectively by natural infrastructure improvements? 01:54:08 Curtis DeGasperi: Potentially useful information? More specific information regarding existing stormwater infrastructure (e.g., detention, infiltration) that would allow some modeling of the flow changes caused by existing infrastructure. I believe the King Co. models incorporate large regional detention facilities, but I don't think we have the data that would allow the inclusion of the many smaller/local constructed facilities that have been build across the regions into the hydrologic models. 01:55:48 Alan Chapman: sorry I am in a warer resources meetin. Double duty. 01:56:23 Lynn Schneider: I am wondering how the massive die off of Doug Fir trees over the past few years is being incorporated into updates of the models? https://www.oregonlive.com/environment/2022/11/record-number-of-firs-dying-in-oregon-washington-in-what-experts-call-firmageddon.html 01:57:48 Ken Pierce: Jonathan, I expect that 5m data is down sampled NLCD data and the suite of "developed/urban" classes are entirely based on modeled impervious surface % so for example a low-density urban pixel only represents land with a specific range of imperviousness but lacks nay information about the other land covers, so a 10%impervious/90% trees would be the same as a 10%impervious/90%bare ground 01:58:20 Lynn Schneider: Thanks! 01:59:50 Philip Murphy: LandTrndr data provides historic harvest info, and covers Puget Sound https://geotrendr.ceoas.oregonstate.edu/landtrendr/ 02:00:06 Gordon Holtgrieve: I did have a question for the group…sorry to be slow with the mute button. 02:00:29 Tessa Francis: @Gordon put up your hand again! 🙂 02:00:58 Ken Pierce: LandTrndr maps Seattle as LOSING impervious surface at the regional level over the post 2005 period. 02:01:26 Shuhui Dun: I am wondering how much monitoring data available to calibration/verify the proposed models and if we need put in more resources to collect site-specific data for model development. 02:01:58 Ken Pierce: LandTrendr, LCC, CCAP are all pretty terrible for mapping urban land cover change 02:03:10 Tech Support: Thank you all, great discussion and reflections on urban land cover change sources! 02:04:05 Jonathan Halama: Hi Ken, The land coverage data were based on the King County high resolution coverage data. I think they started as 1m. We resampled based on majority area. 02:04:37 Michael Connor: It seems that livestock population is quite variable depending on the economy. How accurately are livestock pops tracked and updated 02:06:28 Aaron Clark: Is the Seattle data predicting ‘effective impervious area’ instead? i.e. incorporating GSI that offsets impervious especially in redevelopment? 02:07:11 Ken Pierce: No, what it is mapping, I think, is maturing urban tree canopy that makes it seem like impervious surface is reducing as a byproduct 02:08:55 Lynn Schneider: In response to the question about monitoring data available for calibration. I am curious if we need more data to demonstrate the contributions from on-site sewage systems. Especially as these systems transition from tank to drainfield to complex on-site treatment systems. The complex treatment systems have much greater nutrient reduction capabilities. We need to transition the data inputs to account for the changes in treatment capabilities. 02:08:57 Nick Osman: Hi all: I realized my slides don’t have my email: nosman@thefreshwatertrust.org 02:11:14 Ken Pierce: This should go to the forests paper 10.3390/f8040098 02:11:15 Curtis DeGasperi: :) Could vegetation overhanging roads be an important urban process that isn't considered in these models? 02:12:32 Ken Pierce: Curtis, we're going to start producing a version of our lc maps that try to capture trees over road and in the future trees over buildings 02:13:23 Jonathan Halama: For VELMA, roads and buildings are forced, then using tree LiDAR dataset the trees are overlaided. Finally the remaining is grass or open space. So we are favoring the buildings and roads. 02:14:06 Tessa Francis: Modeling Compendium contribution form: https://docs.google.com/forms/d/e/1FAIpQLSciTkipwMywD7y01uPfBTzTZ66pCSccxAEdaJUwdcx4tLAJBQ/viewform 02:14:12 Genoa Sullaway: To join the Modeling Work Group email: Genoa@uw.edu Modeling Compendium Contribution Form: https://docs.google.com/forms/d/e/1FAIpQLSciTkipwMywD7y01uPfBTzTZ66pCSccxAEdaJUwdcx4tLAJBQ/viewform Updates, recording and slides from todays meeting will be posted here: https://www.pugetsoundinstitute.org/about/waterquality/ 02:14:55 Tessa Francis: And the PSEMP Modeling Work Group will continue to host these workshops so stay tuned! 02:14:57 YI XIONG: thanks a lot! 02:15:02 Su Kyong Yun: Thank you! 02:15:03 Danyel Hiland: Thank you! 02:15:04 Philip Murphy: Tx!
