Assessing wetland habitat quality for Sandhill Cranes (Lindsey Marshall
Lindsey Power conducted a study assessing wetland habitat quality for Sandhill Cranes in the Lower South Platte River Basin in Colorado. She analyzed data on different wetland habitats including emergent marsh, playa, sandbar, river channel, and wet meadow. For roosting habitats, playas scored highest while emergent marshes scored lowest. For feeding habitats, emergent marshes and wet meadows scored similarly and higher than other habitats. The study provides insights that can help inform management recommendations to improve habitats for Sandhill Cranes.
This thesis examines the interaction between aeolian (wind-driven) and fluvial (water-driven) processes of sediment movement and erosion in dry washes on the Colorado Plateau. The author deployed dust traps, conducted wash transects using GPS and photogrammetry, and correlated weather and land use data to quantify the impact of individual erosion events. The results suggest seasonality and land use play a large role in determining the strength of interaction between aeolian and fluvial processes, with high land use and dry, windy conditions most conducive to surface sediment movement and subsequent removal by water. Comparisons between the different data collection methods are also discussed.

Christopher Wright presented his work modeling water infiltration for the City of Bothell. He used soil data, land use/cover data, slope data, and impervious surfaces data in a multi-criteria analysis within a GIS to identify areas suitable for water infiltration. The results showed that suitable areas ranged from 6-24% of the total planning area depending on how the criteria were weighted. Identifying priority infiltration areas will help the city implement programs to increase infiltration and require on-site infiltration in new developments.
This study aims to develop methods to increase CO2-enhanced oil recovery in nonconventional oil reservoirs in Illinois, focusing on the thick Cypress Sandstone. CO2 injection could potentially extract bypassed oil while storing the CO2 underground, mitigating climate change. Geological modeling and petrophysical analysis of core and log data from the Cypress Sandstone will be used to assess the CO2-EOR potential. Findings could aid development of otherwise uneconomical oil resources and remove more carbon from the atmosphere than produced during recovery. The results may demonstrate economic incentives for CO2 storage and reuse in oil production from this nonconventional reservoir.

This document summarizes a study on the biogeochemistry of dissolved nitrogen, phosphorus, and organic carbon along terrestrial-aquatic flowpaths in a montane headwater catchment in the Peruvian Amazon. The study investigated spatial and temporal variations in nutrient concentrations from upland soils to streams under baseflow and stormflow conditions. Key findings include: 1) During baseflow, strong terrestrial controls maintained relatively constant nitrate levels in streams compared to more variable upland soils; 2) Dissolved organic nitrogen dominated stream nitrogen despite decreasing concentrations from uplands; 3) Phosphorus concentrations showed the inverse pattern, with higher levels in streams than uplands. 4) Stoichiometric ratios contrasted between uplands and streams
EVALUATION OF GROUNDWATER QUALITY OF VAIPPAR BASIN, TAMIL NADU, INDIA: A GEOI...SagarChougule11
The Vaippar Basin, one of the important basins of Tamil Nadu is located between 9° 0' 05" & 9° 44' 56" N latitudes and 77° 23' 25" & 78° 17' 02" E longitudes with an area of 5339 sq.km. Groundwater samples were collected from 91 different locations in the Vaippar basin, Tamil Nadu, India. Groundwater quality data for the period of 30 years (1983 to 2013) of both pre-monsoon and post-monsoon periods were used to analyze the groundwater quality aspects of the Vaippar basin. The physico-chemical parameters such as Total Dissolved Solids (TDS), pH, HCO3-, Ca2+, Mg2+, Na+, K+, SO4-, NO3- and Cl have been analyzed to determine the geological and non-geological source of contamination. An overall hydrogeochemical analytical study using Electrical Conductivity, Sodium Adsorption Ratio (SAR), Sodium percentage (Na%) and Residual Sodium Carbonate (RSC) values reveals that most of the groundwater samples collected from the study area are suitable for drinking, irrigation, and industrial purposes.
This study examined the impact of increased infiltration rates on the transport and degradation of the herbicide atrazine in agricultural soils. Column and microcosm experiments were conducted using soils from Nebraska. The results showed that at higher infiltration rates, atrazine transport increased but degradation also increased due to higher soil moisture levels. Overall, atrazine transport was not significantly influenced by the higher infiltration rates because the enhanced degradation limited its movement. The findings suggest that the direct impacts of climate change on contaminant transport in soils are complex and depend on competing degradation and transport processes.

UNCERTAINTY OF HYDROLOGIC EVENTS UNDER SOUTH DAKOTA’S CHANGING CONDITIONS: A ...Boris Shmagin
Widespread flooding across South Dakota in 2011 has spurred a new look at the institutional, regulatory, and mathematical models used to manage the Upper Missouri River Basin as it affects all aspects of life in South Dakota. An SD EPSCoR planning grant was awarded to a team of local, national and international
researchers, who produced a strategy to create a research infrastructure with the goal of developing conceptual and mathematical models to understand and describe the uncertainty of hydrological events (HE) across South Dakota. The strategy involves two main tasks: 1) planning for study of the uncertainty of HE in the Upper Missouri Basin (Shmagin, B. 2011. Missouri River watershed: the object for hydrological study and uncertainty of models. Available from Nature
Precedings at <http: />. [Accessed Oct 3, 2012].)
and 2) developing concepts for communicating uncertainty of HE for wider use outside the professional community. The plan brings together a variety of disciplines, and outlines the development of an artificial intelligence approach to analyzing the interaction of HE, engineering installations and social systems in South Dakota.
The focus of study is the system hydrological researcher – mathematical modeler
– stakeholder, and the process considered is the interaction of knowledge with uncertainty in application to HE. Uncertainty in HE will be defined using concepts broader than hydrology (such as statistical learning) and linked to the concerns of all social, cultural and economic sectors in South Dakota.
Considering this system of interacting participants allows focusing on the principal stages in tackling uncertainty, from developing the research task and obtaining the hydrological results to communication between researcher and stakeholder. Mathematical models are the universal language in scientific research
and will be adapted to bring the results to stakeholders. Three mathematical
approaches to modeling HE and impacts to South Dakota will be considered: 1) distributed system interactions, 2) statistical learning and 3) cellular automata.
Specific concepts of uncertainty for modeling watersheds and describing the time-space variability of water cycles and budget for regional hydrologic study were developed. These concepts include remotely sensed data use, scale and influence of drainage and irrigation on the groundwater regime and hydrology of wetlands and lakes in the Missouri River Valley and Prairie Pothole Region. Additional necessary concepts concern risk assessment and HE interaction with the sociology and economy (e.g., types and scales of regionalization of the physical and human environment), and the design of interactive simulation models (e.g., cartographic presentation and simplified educational modeling after A. Voinov [2008]. of HE in the natural landscapes and industrial/changed conditions in South Dakota.

A 20-year study compared surface runoff quantity and quality from native prairie and cropped livestock grazing systems in central Oklahoma. Runoff, sediment, and nutrient losses were consistently lower from the native prairie (watersheds 1-4) compared to the maximally disturbed watersheds (6 and 8) that were conventionally tilled. The native prairie had increased infiltration and canopy interception, which reduced runoff and erosion. Lower fertilizer inputs to the native prairie also decreased nutrient losses. The long-term data collection contributed to national research networks on agricultural impacts to water quality.

This document summarizes a study of water quality in the Kentucky River watershed from 2001-2006. The author thanks their advisors Dr. Buddhi Gyawali, Jeremy Sandifer, and Ms. Cynthia Rice for guidance. The study analyzed how land use, such as agriculture, mining, and urbanization, impacted water quality. High levels of metals and nutrients were found near mining and urban areas, while low dissolved oxygen levels occurred by agricultural land. The author used GIS data and trend analysis to link changes in water quality parameters to land activities affecting the watershed.
AOPs Report on Resiliency -- Appendices (Final)Steve Gao
This report analyzes the potential impacts of climate change on water supplies for the City of Long Beach by 2030 and 2050. It finds that higher temperatures will reduce snowpack and shift peak runoff earlier in watersheds that supply imported water to Southern California. This will decrease the reliability of imported water supplies by mid-century. Locally, temperatures in Long Beach are projected to increase by 2.3-2.7°F by 2050, increasing demand. Population growth may outpace conservation efforts, raising overall demand. The report recommends expanding local supplies like recycled water and stormwater capture to strengthen Long Beach's resilience to reduced imported water availability due to climate change.
