HIGHLIGHTS - JAWRA AUGUST 2019 [access full table of contents here: https://onlinelibrary.wiley.com/toc/17521688/2019/55/4 ] CELEBRATING 55 YEARS OF JAWRA – SUSTAINED CONTRIBUTIONS TO IMPROVE WATER RESOURCES

ANOTHER INSTALLMENT of Celebrating 55 Years of JAWRA is presented in the August 2019 issue. The editorial highlights some contributions of JAWRA in the fourth decade (1995-2004) focusing on a set of trendsetting papers that defined the human dimensions of water resources and how the then burgeoning internet technologies and advanced data collection methods improved the development of decision support systems for collaborative stakeholder driven decision making. The virtual issue can be found at - https://onlinelibrary.wiley.com/doi/ toc/10.1111/(ISSN)17521688.JAWRA55. Featured Collection – Climate Change Solutions The climate change solutions featured collection guest edited by Drs. Aavudai Anandi, Christine Kirchhoff, and Venkataramana Sridhar presents eight papers that look at vulnerability of water systems to change. These papers focus on practical solutions to addressing how we should adapt to increasing climate risks and what barriers are in our way of mitigating the harmful impacts increased climate extremes can have on water resources systems. A few papers highlighted from the collection include: Paul et al. present a comprehensive literature review focused on Climate change effects on water quality, especially highlighting the changes in flow, temperature, and saltwater intrusion. They conclude the risks will vary in different regional and watershed settings and could present a risk to human health and the environment. Mullin and Kirchhoff study the preparedness of wastewater treatment plant operators’ adaptation to climate change. They find wastewater systems have diverse adaptive capacities and managers who deploy those capacities within an adaptive management framework create systems that are more resilient to storms. Ray et al. propose new advancements in the state of the art in climate change risk management, with emphasis on impact and likelihood aspects of multidimensional analysis. Their work updates the World Bank’s decision tree framework to assess climate risks by incorporating climate extremes and human dimensions. Featured Collection – National Water Model II The second installment of the National Water Model (NWM) featured collection was edited by Dr. Jerad Bales and includes three papers focused on: 1) Hyper-resolution modeling; 2) open-channel hydraulic routing; and 3) hazard communication to the public. Shastry et al . compare the simpler conservation of mass approach currently used in the NWM to a more

comprehensive conservation of momentum-based hydraulic routing model in the Neuse River Basin. Their study suggests the use of hydraulic routing improves,

albeit modestly, flood inundation forecasts in smaller streams. Godbout et al . evaluate the use of synthetic rating curves (SRC) currently used to estimate flood inundation in the NWM. Their study indicates while SRC are sufficient for large- scale approximation of inundation, they are not capable of modeling street-level inundation.

They propose a new method to improve the spatial resolution of flood indundation mapping. Featured Series – Optimizing the Ogallala Aquifer Water Use to Sustain Food Systems This installment of the featured series coordinated by Dr. Prasanna Gowda and edited by Drs. Ryan Bailey, Isaya Kisseka, and Xiaomao Lin include three papers focusing on the performance of AquaCrop and APEX models commonly used to simulate agricultural systems. Masasi et al. use field data from two sites in the Central and Southern High Plains to show the AquaCrop model is effective in simulating the response of sorghum to variable irrigation levels and can be used to study the impact of management practices on sorghum. Talebizadeh et al. report on the development of an open-source parallel computation package developed in R for capturing the dynamics of sensitivity and model performance indices in the APEX model. In addition to papers from the Climate Change Solutions and the National Water Model II collections and an installment of the Optimization of Ogallala Aquifer to Sustain Food Systems featured series, four other technical papers were included in the issue. There are several other articles tackling various water resources issues on the Early View section of JAWRA’s website. Jawra_v55_i4_issueinfo.indd 1
