Salinity Risk Mapping For Assessing Carbon Farming Initiative Proposals: Decision Support And Data Requirements, Paul Raper, Peter Gardiner

Resource management technical reports

The Clean Energy Legislation passed by the Australian Parliament on 8 November 2011 links the carbon price to the Carbon Farming Initiative (CFI). Under the Carbon Credits (Carbon Farming Initiative) Act 2011 (the Act), proponents need to consider regional natural resource management (NRM) plans to ensure that tree plantings for carbon bio-sequestration maximise environmental benefits and avoid unintended adverse effects on biodiversity, water and agricultural production systems.

Floodplain Mapping Using Soil Survey Geographic (Ssurgo) Database, Nikhil Sangwan

Open Access Theses

Floods are the most damaging of all natural disasters, adversely affecting millions of lives and causing financial losses worth billions of dollars every year across the globe. Flood inundation maps play a key role in assessment and mitigation of the potential flood hazards. However, there are several communities in the United States for which the flood risk maps have not been published yet, as the current flood inundation mapping methods are typically very expensive and time consuming. The objective of this study is to develop and examine an economical alternative approach to floodplain mapping using widely available soil survey data. …

Streamflow Modeling Of Johnson Creek Subwatersheds Using The Precipitation Runoff Modeling System, Theophilus Matthew Malone

Civil and Environmental Engineering Master's Project Reports

Johnson Creek, in the Portland, Oregon metropolitan region, has several pollutants on the U.S. Environmental Protection Agency's (EPA) 303(d) list including excess heat, low dissolved oxygen, and harmful bacteria. Understanding streamflow response to precipitation events is an important component to evaluating water quality trends and calculating the Total Maximum Daily Load (TMDL) for pollutants of concern. Investigating the streamflow-precipitation relationship on the subwatershed scale can give insight to the hydrologic response of a given watershed. However, developing rating curves for several subwatersheds can be cost and time prohibitive. The objective of this project was to develop a hydrologic model using …

Similar Resilience Attributes In Lakes With Different Management Practices, Didier L. Baho, Stina Drakare, Richard K. Johnson, Craig R. Allen, David G. Angeler

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Liming has been used extensively in Scandinavia and elsewhere since the 1970s to counteract the negative effects of acidification. Communities in limed lakes usually return to acidified conditions once liming is discontinued, suggesting that liming is unlikely to shift acidified lakes to a state equivalent to pre-acidification conditions that requires no further management intervention. While this suggests a low resilience of limed lakes, attributes that confer resilience have not been assessed, limiting our understanding of the efficiency of costly management programs. In this study, we assessed community metrics (diversity, richness, evenness, biovolume), multivariate community structure and the relative resilience of …

Groundwater Flow Across Spatial Scales: Importance For Climate Modeling, Nir Krakauer, Haibin Li, Ying Fan

Publications and Research

Current regional and global climate models generally do not represent groundwater flow between grid cells as a component of the water budget. We estimate the magnitude of between cell groundwater flow as a function of grid cell size by aggregating results from a numerical model of equilibrium groundwater flow run and validated globally. We find that over a broad range of cell sizes spanning that of state of the art regional and global climate models, mean between cell groundwater flow magnitudes scale with the reciprocal of grid cell length. We also derive this scaling a priori from a simple statistical …

Water Movement Through The Unsaturated Zone Of The High Plains Aquifer In The Central Platte Natural Resources District, Nebraska, 2008-12, Gregory V. Steele, Jason J. Gurdak, Christopher M. Hobza

United States Geological Survey: Water Reports and Publications

Uncertainty about the effects of land use and climate on water movement in the unsaturated zone and on groundwater recharge rates can lead to uncertainty in water budgets used for groundwater-flow models. To better understand these effects, a cooperative study between the United States Geological Survey (USGS) and the Central Platte Natural Resources District (CP NRD) was initiated in 2007 to determine field-based estimates of recharge rates in selected land-use areas of the CP NRD in Nebraska. Measured total water potential and unsaturated-zone profiles of tritium, chloride, nitrate as nitrogen, and bromide, along with groundwater-age dates, were used to evaluate …

Earth's surface is rapidly urbanizing, resulting in dramatic changes in the abundance, distribution and character of surface water features in urban landscapes. However,the scope and consequences of surface water redistribution at broad spatialscales are not well understood. We hypothesized that urbanization would lead to convergent surface water abundance and distribution: in other words, cities will gain or lose water such that they become more similar to each other than are their surrounding natural landscapes. Using a database of more than 1 million water bodies and 1 million km of streams, we compared the surface water of 100 US cities with …

Are Climate Model Simulations Useful For Forecasting Precipitation Trends? Hindcast And Synthetic-Data Experiments, Nir Y. Krakauer, Balázs M. Fekete

Publications and Research

Water scientists and managers currently face the question of whether trends in climate variables that affect water supplies and hazards can be anticipated. We investigate to what extent climate model simulations may provide accurate forecasts of future hydrologic nonstationarity in the form of changes in precipitation amount. We compare gridded station observations (GPCC Full Data Product, 1901–2010) and climate model outputs (CMIP5 Historical and RCP8.5 simulations, 1901–2100) in real and syntheticdata hindcast experiments. The hindcast experiments show that imputing precipitation trends based on the climate model mean reduced the root mean square error of precipitation trend estimates for 1961–2010 by …

Environmental Science and Management Faculty Publications and Presentations

We review how urbanization alters aquatic ecosystems, as well as actions that managers can take to remediate urban waters. Urbanization affects streams by fundamentally altering longitudinal and lateral processes that in turn alter hydrology, habitat, and water chemistry; these effects create physical and chemical stressors that in turn affect the biota. Urban streams often suffer from multiple stressor effects that have collectively been termed an “urban stream syndrome,” in which no single factor dominates degraded conditions. Resource managers have multiple ways of combating the urban stream syndrome. These approaches range from whole-watershed protection to reach-scale habitat rehabilitation, but the prescription …

Towards Improving Drought Forecasts Across Different Spatial And Temporal Scales, Shahrbanou Madadgar

Dissertations and Theses

Recent water scarcities across the southwestern U.S. with severe effects on the living environment inspire the development of new methodologies to achieve reliable drought forecasting in seasonal scale. Reliable forecast of hydrologic variables, in general, is a preliminary requirement for appropriate planning of water resources and developing effective allocation policies. This study aims at developing new techniques with specific probabilistic features to improve the reliability of hydrologic forecasts, particularly the drought forecasts. The drought status in the future is determined by certain hydrologic variables that are basically estimated by the hydrologic models with rather simple to complex structures. Since the …

Daugherty Water for Food Global Institute: Faculty Publications

Society has a universal need for water that crosses all sectors of activity. We need to be able to measure progress towards sustainable water for all by working towards targets that consider the different dimensions of water resources and use, including water quantity and quality. A suite of indicators that reflect water use by different sectors is needed to measure progress towards the forthcoming SDGs’ [sustainable development goals] water-related targets. Such indicators will need to rely on national data, must consider the variation in data availability, and can be complemented with new cost-effective ways for data collection.

Water-Food-Energy Nexus, Jeremy Bird, Felix Dodds, Peter G. Mccornick, Tushaar Shah

Daugherty Water for Food Global Institute: Faculty Publications

The proposed SDGs on water, food and energy security all include targets on increasing efficiencies. Yet the water–food–energy nexus has multiple dimensions that, if managed in isolation, will compromise a nation’s ability to achieve the full portfolio of SDGs.

Climate change introduces additional uncertainties, further increasing tensions between sectors for access to water. Conventional energy and food production are emitters of greenhouse gases, but measures to reduce emissions—including renewable energy interventions, such as subsidies for biofuel production—can have adverse consequences on food prices.

To achieve desirable and sustainable outcomes for water, food, and energy requires investigating these elements as an …

Daugherty Water for Food Global Institute: Faculty Publications

Elevated level of fluoride (F⁻) in drinking water is a well-recognized risk factor of dental fluorosis (DF). While considering optimization of region-specific standards for F⁻, it is reasonable, however, to consider how local diet, water sourcing practices, and non-F⁻ elements in water may be related to health outcomes. In this study, we hypothesized that non-F⁻ elements in groundwater and lifestyle and demographic characteristics may be independent predictors or modifiers of the effects of F⁻ on teeth. Dental examinations were conducted among 1094 inhabitants from 399 randomly selected households of 20 rural communities of …
