 Well, then we will move right to our third speaker who is Stacy Archfield from the US Geological Survey. Hi, I'm Stacy I don't have a presentation planned. I'm also like full disclosure a surface water modeler So but but my background is in surface water and statistics and that's really how I interface with the groundwater modeling at least Activities at the US Geological Survey. So some of the things that we have there that involve both surface and groundwater is a large Congressionally mandated project to model the Mississippi alluvial plane, which is a large highly human dominated, I would say aquifer And so there the piece is how do you constrain properly? Groundwater modeling with surface water in data sparse regions and complex hydrology hydrogeology So that's one aspect where I've been involved as an advisor and reviewer I've also been working with Lenny Conakow and Bob Hirsch on looking at the relationship between groundwater depletion and Trends in low flows and low flow extremes and there what we're finding is the confounding effects of Different aspects that affect the groundwater Depletion it makes it very difficult to understand it to find actually strong correlations Between low stream flows for the principal aquifers and groundwater depletion, which was kind of been a surprising result for us It's not very clear that signal because other factors are coming into play like precipitation is increasing generally Across the United States and so that's confounding the effects of how stream flow depletion relates to low flow extremes So that's another piece of work that I've been involved in that's going to frame some of my comments today I've also done work in transferring information from gauge to ungaged locations Which I've always been interested in how that might relate to groundwater and how we might be able to transfer Information where we have we're monitoring wells high High temporal resolution of monitoring of water levels and things like that and how that might translate actually to Places where we don't have such as extreme monitoring network Particularly for things like groundwater surface water coupled stream gauges, which we have a limited Set of it from the USGS, but we could certainly look to expand that information Those are some of the ways that I've been engaged with kind of my surface water background plugging into to groundwater Modeling so I'm gonna stop there
