Identifying Changes In Climatic Trends And The Fingerprints Of Landuse And Landcover Changes In The High Plains Of The Usa, Denis Mutiibwa Jul 2011

Identifying Changes In Climatic Trends And The Fingerprints Of Landuse And Landcover Changes In The High Plains Of The Usa, Denis Mutiibwa

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Human activities such as conversion of natural ecosystem to croplands and urban-centers, deforestation and afforestation impact biophysical properties of land surface such as albedo, energy balance, and surface roughness. Alterations in these properties affect the heat and moisture exchanges between the land surface and atmospheric boundary layer. The objectives of this research were; (i) to quantitatively identify the High plains’ regional climate change in temperatures over the period 1895 to 2006, (ii) detect the signatures of anthropogenic forcing of LULC changes on the regional climate change of the High Plains, and (iii) examine the trends in evolving regional latent heat …

The first step in managing large-scale (national) collaborations and networks is to consider and address how a group and a potential partnership may match up (Luther, 2005). To explore this concept and many other collaborative concepts, the National Integrated Drought Information System (NIDIS) hosted a workshop, “Building a Sustainable Network of Drought Communities,” which was facilitated by the National Drought Mitigation Center (NDMC) in Chicago, IL, June 8-9, 2011.

The workshop explored current examples of good communication and lessons learned within the realm of drought planning in order to address a future NIDIS Engaging Preparedness Communities (EPC) working group that …


Spatial Patterns Of Drought Triggers And Indicators, Joseph P. Robine May 2011

Spatial Patterns Of Drought Triggers And Indicators, Joseph P. Robine

Department of Environmental Studies: Undergraduate Student Theses

Drought is a reoccurring phenomenon with widespread economic, social, and environmental impacts. Unlike other disasters, a drought cannot be easily detected. In addition, droughts are widespread and develop slowly over time making it difficult to detect its onset and monitor its severity and impacts. To assist in monitoring the severity and spatial extent of droughts, drought managers frequently use indicators and triggers. Drought indicators are meteorological or hydrological variables or indices that quantify or describe the level of drought severity. A drought trigger is a value of an indicator that initiates management and response actions. Despite the clear importance of …

Evaluation Of Drought Indices Based On Thermal Remote Sensing Of Evapotranspiration Over The Continental United States, Martha C. Anderson, Christopher R. Hain, Brian Wardlow, Agustin Pimstein, John R. Mecikalski, William P. Kustas Apr 2011

Evaluation Of Drought Indices Based On Thermal Remote Sensing Of Evapotranspiration Over The Continental United States, Martha C. Anderson, Christopher R. Hain, Brian Wardlow, Agustin Pimstein, John R. Mecikalski, William P. Kustas

National Drought Mitigation Center: Faculty Publications

The reliability of standard meteorological drought indices based on measurements of precipitation is limited by the spatial distribution and quality of currently available rainfall data. Furthermore, they reflect only one component of the surface hydrologic cycle, and they cannot readily capture nonprecipitation-based moisture inputs to the land surface system (e.g., irrigation) that may temper drought impacts or variable rates of water consumption across a landscape. This study assesses the value of a new drought index based on remote sensing of evapotranspiration (ET). The evaporative stress index (ESI) quantifies anomalies in the ratio of actual to potential ET (PET), mapped using …

Mapping Acid Groundwater In Western Australia’S Wheatbelt, Karen Holmes, Adam Lillicrap Feb 2011

Mapping Acid Groundwater In Western Australia’S Wheatbelt, Karen Holmes, Adam Lillicrap

Resource management technical reports

The extent of the area affected by deep drains in Western Australia (more than 11 000 km of drains installed as of 2002: Australian Bureau of Statistics 2002) and their continuing installation by land managers make understanding the distribution of naturally occurring acid groundwater a priority for land managers working toward sustainable agricultural production in the wheatbelt. This report describes development of a map of the likelihood of acid groundwater occurrence. It is meant to guide state agencies, natural resource management groups, landholders, and community stakeholders on where acid groundwater may occur.

A Financial Impact Assessment Of Ld 1725: Stream Crossings (Presentation), New England Environmental Finance Center, Muskie School Of Public Service

Water

This report looks at the potential financial impact of LD 1725 on the estimated 30,000 stream crossings in the State of Maine that would be affected by the law. Our research for this report included the analysis of nearly 2000 stream crossings and the data collection necessary for the development of extensive stream crossing replacement cost models. We found that the 1.2 bankfull requirements in LD 1725 would result in a 75% ‐ 250% increase in structure widths for stream crossing projects across the state. An upsize of this magnitude would increase the cost of replacing stream crossings statewide by …

Farmer Perceptions Of Sustainable Agriculture Practices And Drought Risk Reduction In Nebraska, Usa, Cody L. Knutson, Tonya Haigh, Michael J. Hayes, Melissa Widhalm, J. Nothwehr, M. Kleinschmidt, L. Graf Jan 2011

Farmer Perceptions Of Sustainable Agriculture Practices And Drought Risk Reduction In Nebraska, Usa, Cody L. Knutson, Tonya Haigh, Michael J. Hayes, Melissa Widhalm, J. Nothwehr, M. Kleinschmidt, L. Graf

National Drought Mitigation Center: Faculty Publications

Social factors, such as farming methods, have an impact on farm vulnerability to drought, but have received little research or policy attention. Some researchers and advocates have argued that sustainable agriculture systems are less vulnerable to climate risk than conventional systems because sustainable agriculture requires producers to have skills promoting adaptability. In this paper, we investigate producers’ perceptions on the use of sustainable agriculture in reducing drought risk, and what they believe would help them better adapt to drought. We surveyed and interviewed farmer members of two sustainable agriculture organizations in Nebraska, USA, during a multi-year drought period from 1999 …


The Global Drought Monitor Portal, Michael J. Brewer, Richard R. Heim Jr. Jan 2011

The Global Drought Monitor Portal, Michael J. Brewer, Richard R. Heim Jr.

National Drought Mitigation Center: Faculty Publications

Drought monitoring, assessment, response, mitigation, adaptation, and early warning systems have been created in a number of countries around the world, and some regional and continental efforts have been successful. However, the creation of a Global Drought Early Warning System (GDEWS) remains elusive. A GDEWS incorporates forecasting and research improvements, in addition to monitoring, impact, planning, mitigation and adaptation and recovery information. At a series of workshops in 2010, the U.S. National Integrated Drought Information System (NIDIS) agreed to take the first step toward a GDEWS, the formation of a Global Drought Monitoring Portal (GDMP). This effort currently covers three …

Influence Of Karst Landscape On Planetary Boundary Layer Atmosphere: A Weather Research And Forecasting (Wrf) Model–Based Investigation, Ronnie Leeper, Rezaul Mamood, Arturo I. Quintanar Jan 2011

Influence Of Karst Landscape On Planetary Boundary Layer Atmosphere: A Weather Research And Forecasting (Wrf) Model–Based Investigation, Ronnie Leeper, Rezaul Mamood, Arturo I. Quintanar

High Plains Regional Climate Center: Staff Publications

Karst hydrology provides a unique set of surface and subsurface hydrological components that affect soil moisture variability. Over karst topography, surface moisture moves rapidly below ground via sink holes, vertical shafts, and sinking streams, reducing surface runoff and moisture infiltration into the soil. In addition, subsurface cave blockage or rapid snowmelt over karst can lead to surface flooding. Moreover, regions dominated by karst may exhibit either drier or wetter soils when compared to nonkarst landscape. However, because of the lack of both observational soil moisture datasets to initialize simulations and regional land surface models (LSMs) that include explicit karst hydrological …

Geochemical Analysis Of Surface And Ground Waters Around Cle Elum, Wa; Implications For The Proposed Exempt Well Moratorium, David Hickey, Ryan Opitz, Carey A. Gazis Sep 2010

Geochemical Analysis Of Surface And Ground Waters Around Cle Elum, Wa; Implications For The Proposed Exempt Well Moratorium, David Hickey, Ryan Opitz, Carey A. Gazis

Student Published Works

The Yakima River drainage is one of the most heavily irrigated regions in the state, and water use has been much contested and litigated. Due to this water demand and the increase in drilling of domestic wells, a moratorium on exempt well drilling was proposed in 2007. In this study geochemical data is used to evaluate the surface-groundwater interaction in the area around Cle Elum, WA. The hydrogeology of this area is poorly understood due to the complex stratigraphy where the valley floor meets the bedrock of the Cascade Range. It is important to understand the relationship between groundwater and …

Effects Of Drought On Avian Community Structure, Thomas P. Albright, Anna M. Pidgeon, Chadwick D. Rittenhouse, Murray K. Clayton, Curtis H. Flather, Patrick D. Culbert, Brian D. Wardlows, Volker C. Radeloff

National Drought Mitigation Center: Faculty Publications

Droughts are expected to become more frequent under global climate change. Avifauna depend on precipitation for hydration, cover, and food. While there are indications that avian communities respond negatively to drought, little is known about the response of birds with differing functional and behavioral traits, what time periods and indicators of drought are most relevant, or how response varies geographically at broad spatial scales. Our goals were thus to determine (1) how avian abundance and species richness are related to drought, (2) whether community variations are more related to vegetation vigor or precipitation deviations and at what time periods relationships …
