Water Systems Analysis and Policy Research Group
We study the impacts of design and policy choices on the performance of water infrastructure systems under changing conditions. To do this we apply systems analysis methods to understand feedbacks in coupled human-hydrological systems, assess the role of design choices, and inform decision making.
We collaborate with research groups at ASU and beyond to apply interdisciplinary approaches to address pressing water resources and infrastructure challenges. We are part of the School of Sustainable Engineering and the Built Environment and the Global Institute of Sustainability at ASU. Our students are part of graduate programs in Sustainable Engineering and Hydrosystems Engineering and undergraduate programs in Civil and Environmental Engineering.

We have a few pieces of news to report as the summer wraps up. First, we recently had a new paper accepted in Global Environmental Change comparing water managmenet transitions in three U.S. cities. The paper presents work funded by a graduate pursuit grant from SESYNC. Second, we received funding from the NSF to extend the work from the paper to a dozen cities with two members from the SESYNC team and two new Co-PI's. We'll be hiring PhD students at ASU in Civil Engineering and the School of Sustainability, so send a note using the contact page if you're interested. The project is funded by the NSF program on Coupled Human-Natural Systems (award 1923880) and more info can be found here: https://web.asu.edu/mgarcia/research

Our team has had a busy summer so far. First, in May we welcomed Behshad Mohajer as the newest PhD student in the group. Behshad has his MSc. degree in Water Resources Engineering and Management and BSc. degree in Civil Engineering from Tehran Azad University. Prior to ASU he worked for UNICEF in their WASH division. Second, Annika presented her honors thesis at the ASCE EWRI meeting and won third place in the student poster competition – congrats Annika! Next, in June PhD student Ashish headed to Yunnan University to participate in a Summer Research Institute on Transboundary Water Management. He’s working with a team of students from around the world analyzing case studies to identify drivers of cooperation and conflict in transboundary water. Prof. Garcia joined the students in Yunnan for two weeks as a faculty adviser. Many thanks to Prof. Fuqiang Tian of Tsinghua University for organizing and inviting us. Last, but not least, we are excited to report our first NSF grant as lead. The project on Cross-Scale Interactions & the Design of Adaptive Reservoir Operations is in collaboration with colleagues at Purdue and University of Illinois will being in August.

A new paper on adaptive infrastructure was recently published in collaboration with ASU colleagues Mike Chester and Brad Allenby. Erica Gilrein, masters student in Chester's group, led the project which developed a database of existing technologies and strategies that can increase infrastructure flexibility.
We also congratulate Dillon Nys on finishing his MS in Environmental Engineering. Durnig his masters Dillon worked with Margaret Garcia on a research paper examining institutional and infrastructural influences on water stress in Los Angeles and completed an applied project. For his applied project Dillon developed a mathematical model, BioSim, of a fully-enclosed human habitat where all resources (air, water, food) are recycled and regenerated. BioSim models the flows and fluxes of these resources throughout the system as they change over time using a system of physical equations and discrete time steps. The equations used for modeling are presented alongside results and the MATLAB code for more in-depth analysis of the individual components. More info can be found on his github site: https://github.com/dnys1/biosim Great job Dillon and best of luck in your new job!
We also congratulate Kiran Pendyla on finishing his BS and successfully completing his honors thesis. Kiran conducted an exploratory analysis on water use trends using household level water use data from the City of Santa Monica, CA. He developed a series of scripts to organize, clean and visualize the data and completed a cluster analysis identifying groups of water users with similar time series behavior. Nice work Kiran and best of luck in your new job!

Three papers from the group have been recently accepted for publication. One of papers, accepted to the Urban Water Journal, describes an analysis of water use data from the city of Las Vegas and the development of a model to assess the impact of external and emergent factors on per capita water use. The second paper, accepted at the Journal of Environmental Studies and Sciences, evaluates the effectiveness of the SESYNC graduate pursuit program in building interdisciplinary and team science skills in PhD students. The third paper is an introduction to the special issue on Socio-Hydrology in Water Resources Research discussing the state of the field, contributions of the special issue, and areas for growth. See publications page for more details. Additionally, Annika's thesis work has been accepted as a poster and conference paper at the 2019 ASCE Environmental and Water Resrouces Institute conference.

Annika, Civil Engineering undergraduate student in the Barret Honors program, successfully defended her thesis on the Effect of Drought Policies on Los Angeles Water Demand. In her work she created a comprehensive data base of local, county and state conservation policies and assessed their role, in conjunction with hydroclimatic and socio-economic variability, in explaining the observed decline in per capita water use. Annika’s thesis work was supported by the ASU Fulton Undergraduate Research Initiative (FURI).

We kicked off a new multi-university project to assess the effectiveness of several real-time flood detection, reporting, and communication technologies for cities and local communities. The project is supported by the National Science Foundation's Smart and Connected Communities program (award 1831475). We will be working in collaboration with Giuseppe Mascaro and Mikhail Chester at ASU and colleagues at NAU, University of Arizona, Michigan Tech, and University of Buffalo. In our group we will be developing urban hydrological models for Phoenix and Flagstaff to pilot the integration of a novel combination data sources (flood cameras, citizen science reports, traffic cameras, and social media) with traditional data and forecasts to provide real time flood alerts. We’ll be providing periodic updates on our project website: http://floodaware.net/

We welcomed two new graduate students into the research group for the Fall 2018 semester. Ashish Shrestha join the group as a new graduate student pursuing his PhD. Student in Sustainable Engineering. Ashish will work on the integration of new information sources to predict and mitigate urban flooding. Dillon Nys, masters student in Environmental Engineering, is assisting with Prof. Garcia with ongoing work on urban water stress and reservoir operations and will be completing his applied project in the Spring of 2019.
