This paper describes the geospatial river network (“hydro-fabric”), physics, and parameters of the NWM, elucidating the challenges of extrapolating parameters a large scale with limited observations. A set of regression-based channel geometry parameters are evaluated for a subset of the 2.7 million NWM reaches, and the riverine compound channel scheme is described. Based on the results from regional streamflow experiments within the broader NWM context, the compound channel reduced the root mean squared error by 2% and improved median Nash–Sutcliffe efficiency by 16% compared with a non-compound formulation. Peak event analysis from 910 peak flow events across 26 basins matched from the US Flash Flood Observation Database revealed that the mean timing error is 3 h lagged behind the observations. The routing time step was also tested, for 5-min (default, operational setting) and 1-h increments. The model was computationally stable and able to convey the flood peaks, although the hydrograph shape and peak timing were altered.</p>","PeriodicalId":17234,"journal":{"name":"Journal of The American Water Resources Association","volume":"59 5","pages":"1051-1066"},"PeriodicalIF":2.4,"publicationDate":"2023-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50140196","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 2008, the Scientific Surveys came home to where it all started, the University of Illinois, under the umbrella of the Prairie Research Institute with the addition of the Illinois Sustainability and Technology Center and Illinois State Archeological Survey. Together, the Prairie Research Institute has over 800 scientists, technicians, post-docs, research affiliates, visiting scholars, students, and administrative support staff, conducting transformative science that benefits the people, economy, and environment of Illinois, the nation, and the world. From their inception, the Scientific Surveys have always been located on the University of Illinois campus and continues to capitalize on the mutual benefits of collaboration with faculty and staff.&lt;/p&gt;&lt;p&gt;The papers presented in this special issue marking the 125th anniversary founding of the ISWS are but a representation of the current contributions and research being conducted by ISWS scientists and colleagues, aiming to demonstrate what Illinois experiences in water resources planning and management under changing conditions, especially changing climate. They build on water supply planning legacy by incorporating future demands and climate uncertainties in Illinois, including the major updating of Illinois precipitation frequency standards. The theme of understanding uncertainties and bias continues in evaluating groundwater static head measurements to understand water-level variability. Of course, projecting climate change impacts is paramount to many water resource issues and authors discuss which climate ensemble approaches produce less uncertain climate model outputs. Nutrient losses in US agricultural lands are an issue not only for loss of crop production but downstream impacts. Winter cover crops have much promise for reducing nitrate, phosphorus, and sediment loads. Authors present possible detrimental impacts on storage volumes for downstream reservoirs in drought years. An Illinois River watershed analysis presents evidence that spatial and temporal shift in phosphorus loading affects recent increases in phosphorus despite point and nonpoint source efforts. The ISWS has long-term datasets which contributed to improved model calibration to capture chloride accumulation in shallow aquifers. Reservoirs serve populations and industry so understanding outflows from them is important for water resource planning and management. Comparing performance of three machine learning models shows promise for simulating reservoir outflow.

Questions like, “Do we have less suitable drinking water now than we had 20 years ago?” or “Are flood events more common now than they were in the past?” prompted improvements in data, trend estimation methods, and modeling frameworks to track changes in, and better understand how land use and climate influence four water resources domains: surface and groundwater quantity and quality. However, continued advancement in trend assessments to better address issues related to changes in water availability is needed. Areas of need include more timely and efficient delivery of water resources trend results and improved capacity to estimate trends at unmonitored locations. Additional integration pieces include increased understanding of groundwater–surface water interactions, incorporation of both quantity and quality trends into water availability estimates, and the refinement of trend metrics to account for the competing needs of society and ecological integrity.

The analysis of the method reveals nonlinear recession which can result from the down-valley flow component, a dual-aquifer effect, and leakage to or from the aquifer. Important concepts include the dominant recession index and secondary recession characteristics which can affect low flow. Under conditions of down-valley flow, the cross-valley flow component tends to be important for determining recession characteristics, including hydraulic diffusivity and the recession index.

This study uses the 2019 American Housing Survey to produce the first joint, nationally-representative analysis of household reliance on wells and septics in decades. We find that there are lower proportions of U.S. households off the regulated water grid than other contemporary estimates. We also find that while 9.1% of U.S. households rely on both private well and septics simultaneously, a slightly higher proportion of households rely on only one of these systems, with the companion infrastructure being publicly regulated. Our results show that both private well and septic reliant households are much more likely to be non-Hispanic White, live in a single family home (a detached or attached one-family dwelling) or mobile home (a portable habitable structure that was originally fitted with wheels to facilitate movement), and to live outside a metropolitan area than those reliant on publicly regulated service. Yet, surprisingly both private well and septic reliant households do not have lower average incomes than households reliant on regulated systems. These results suggest that federal, state and local financial assistance, technical assistance and educational programs can be better targeted to ensure that in-need private well and septic reliant households can operate and maintain their essential water and sanitation infrastructure.</p>","PeriodicalId":17234,"journal":{"name":"Journal of The American Water Resources Association","volume":"59 6","pages":"1397-1412"},"PeriodicalIF":2.4,"publicationDate":"2023-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113970133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We evaluated temporal trends and variations in agricultural water use and hydroclimatic variables including precipitation, air temperature, reference evapotranspiration, runoff, groundwater level, and terrestrial water storage across the HPA region for different periods from 1985 to 2020 at the grid, county, or region scale. The results showed that water withdrawals decreased from 21.3 km³/year in 1985 to 18.2 km³/year in 2015, while irrigated croplands increased from 71,928 km² in 1985 to 78,464 km² in 2015 in the entire HPA. The hydroclimatic time-series showed wetting trends in most of the northern HPA, but drying and warming trends in the southern region from 1985 to 2020. The groundwater level time-series indicated flat trends in the north, but significant declining in the central and southern HPA.
