CHyMP recognizes that it is difficult to evaluate and access many existing hydrologic models and the data needed to calibrate them, and these shortcomings impede scientific progress. The third CHyMP workshop, “A Strategic and Implementation Plan,” funded by the U.S. National Science Foundation and the University of California Center for Hydrologic Modeling, brought together more than 30 participants from universities, government agencies, and the private sector to focus on defining step...

Understanding the larger scale dynamics of these events is critical to improving predictability, management and mitigation strategies. The history of drought in the United States shows both long (multi-decadal) and short (seasonal or yearly) droughts in various regions. Some of the most severe droughts, such as those with the largest economic losses or that have received the most attention both from the scientific and broader communities have occurred in the Midwest/Great Plains (e.g. the "Dust Bowl" years, the 1988 drought) and generally correlate with continent-wide anomalies. The Southeast region of the US, while generally having a more humid temperature climate than the rest of the country, also is subject to periods of drought conditions. In this study we analyze long term records of PDSI in the southeastern United States. While some occurrences c...

Therefore, understanding drivers, patterns, and changes in observed streamflow provide insight to both the physical functioning of a system and the possible applications for human-water system management. This study examines seasonality of the forcings of temperature and precipitation in conjunction with measured and modeled runoff to investigate 20th century climate and anthropogenic changes in the water balance in the Merrimack River (NH/MA). Seasonality statistics are generated for temperature, precipitation and observed streamflow for the 20th century, and examined for changes. Monthly runoff is generated using the USGS Thornwaite model using observed temperature and precipitation. Correlation between modeled monthly runoff and measured streamflow, and sea...

To investigate the presence of non-local interactions, locations are modeled as a set of independent columns and the moisture-outflow relationships are aggregated in such a way as to account for heterogeneity; this estimate is compared statistically to the large-scale response estimated from aggregate data. Significant differences would suggest the system is not well represented by the independence assumption, i.e. local outflow is dependent on local moisture and also is independently influenced by large-scale moisture. We applied these methods to data from three systems - a hillslope, an intermediate-sized watershed, and the state of Illinois, and found that heterogeneity coupled with...

The availability of fresh water resources in the future is likely to be limited as well as a source of dispute between states and nations. In the United States, water resources have been a major concern in the West for many years. In recent years, droughts have raised awareness in the South as well. With the possibility of future fresh water shortages increasing, a methodology for predicting future conditions is needed. This research outlines a methodology to estimate future conditions based on the influence of climate change, land use change, and population growth. The method is based on the UGSG Thornthwaite monthly water balance model, and can incorporate estimates of climate change and land use change parameters, to assess future water resources based on predicted monthly fluxes. The methodology is demonstrated by analyzing the lower Cape Fear River basin located in southeast North Carolina. This region ...

Advancing water science requires discovering, integrating, and analyzing data from these diverse sources as well as collaboration between different Earth science disciplines and computer and information scientists.
