CUAHSI's 2018 Winter Cyberseminar Series:

Urban Stormwater Hydroinformatics

Wednesdays in February at 1:00 p.m. Eastern Time

Host: Randy Dymond (Virginia Tech)

This timely cyberseminar series addresses a mashup of the serious problems that today’s cities are facing with flooding, inadequate information about their infrastructure, the critical need for monitoring water quantity and quality holistically, and the role of modeling for performance and scenario evaluation.

    Developing and Utilizing Stormwater’s “Big” Dataset

    Virginia Tech researchers worked with various municipalities to implement innovative mobile, cloud-based GIS to develop, deploy, and utilize data for watershed master planning, hydrologic/hydraulic modeling, stormwater inspections, regulatory compliance, and infrastructure asset management. Procedures taken to build, troubleshoot, and improve the stormwater GIS are described, as are required personnel needs, data collection rates, and workflow scaling considerations. Various innovative scripts and tools used to develop and use this cloud-based GIS will be described, and the outcomes of this workflow will be presented with examples from two Virginia localities.

    Enabling “Smarter” Urban Watersheds

    We will discuss how recent advances in sensing, wireless communications and cloud computing are ushering in new opportunities for the adaptive management of urban watersheds. In particular, we introduce, an open source initiative aimed at enabling “smart” urban watersheds. We will illustrate how the flow and quality of water can be resolved in real-time across unprecedented spatiotemporal scales, allowing for a true system-level understanding of urban hydrology and stormwater systems.  Furthermore, we will show how real-time control, in the form of many distributed valves can be used to control and adapt watersheds on a storm-by-storm basis. We will discuss two case studies, which have been built entirely on Open-Storm technologies. The first is a large flash flood warning system in Dallas Texas. The second is a 10mi2 “smart” stormwater system in Ann Arbor, which is currently being controlled in rea-time to meet a variety of flood-reduction and water quality goals. We will also discuss the outcomes of a joint urban watershed sensing workshop that was co-hosted by CUAHSI and the University of Michigan.

    Urban Hydrology and the National Center for Infrastructure Modeling and Management (NCIMM)

    NCIMM has been funded by the US EPA to build and enhance the open-source modeling communities surrounding the EPA Storm Water Management Model (SWMM) and the EPANET water distribution model.  SWMM in particular represents the combined efforts of a large, diverse, and committed community of stakeholders over decades and around the globe, and both tools are used around the world, by many thousands of users, in practical applications and research.  The NCIMM views its role as a trust to continue this legacy, and combines efforts in research, code development, and broad outreach to engage the broader community of researchers, municipalities, engineering firms, software vendors, and others who have a stake in the future of these models. In this webinar, we will discuss the goals and future plans of NCIMM, and invite discussions as to ways that NCIMM can work with CUAHSI members in advancing modeling science for urban hydrology, watershed management, water distribution systems, and related application areas.

    Watershed-scale Effectiveness of Green Infrastructure

    The cumulative effectiveness of detention, infiltration, and harvest-focused stormwater management on a watershed-scale in maintaining urban watershed function has not been straightforward to observe or predict.  This presentation will discuss the results of a watershed-scale green infrastructure implementation in Clarksburg, Maryland in terms of watershed hydrology and function.  Combining this case study with others on networks of stormwater management, hypotheses of how watershed-scale hydrologic and water quality response would change in response to implementation of different types of stormwater management will be presented.  The monitoring and urban hydroinformatics needed in order to detect these responses and test these hypotheses will be discussed.
