Publications and Research

Charles Alexander Baskerville captured our imagination, as a senior colleague in the practice of engineering geology in New York City. “Charlie” held the seat of master Big Apple Geologist during his matured career. He was the source, he knew the possibilities, he was aware of the pitfalls of this most geologically complex of American cities. His final work was his greatest reach—the four bedrock geologic quadrangles of the city. Baskerville mapped New York City for more than fifty years. He was sought and given access to sites of bedrock and bedrock/ overburden interface on the various capitol construction projects undertaken …

Groundwater: Solution To The Las Vegas Water Problem?, Rosa Perez, Christopher Ruiz

Festival of Communities: UG Symposium (Posters)

A contentious debate is taking place in different sectors of the community on how to manage the states groundwater system. It is a battle whose outcome, regardless of who wins, will have a tremendous impact on the future of Las Vegas. Economic benefits always seem to downplay environmental considerations in the policy-making process often with serious consequences. This paper takes a look at the SNWAʼs Groundwater Development Project and provides a discussion of the issues for and against it. Groundwater is inexpensive, relatively abundant and accessible. However, over-pumping of groundwater can have significant environmental consequences, as well. It is our …


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 …

Review Of The River Returns: An Environmental History Of The Bow. By Christopher Armstrong, Matthew Evenden, And H.V. Nelles., Ted Binnema, David Vogt Apr 2011

Review Of The River Returns: An Environmental History Of The Bow. By Christopher Armstrong, Matthew Evenden, And H.V. Nelles., Ted Binnema, David Vogt

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

This book should be read more as a collection of essays on a wide variety of topics related to the Bow River than as a monograph. Each of its thirteen chapters examines an aspect of the history of human interactions with the river, ranging from ranching, forestry, hydroelectricity, and irrigation to urban sanitation, recreational fishing, flooding, and park building. The Bow River is amenable to a discussion of such diverse themes. Its headwaters are among the glaciers of the Rocky Mountains in Banff National Park, but it also flows through the ranching country of the foothills, the major urban center …


Estimation Of Land Surface Evapotranspiration With A Satellite Remote Sensing Procedure, Ayse Kilic, Ian Ratcliffe, Pariskhit Ranade, Kenneth Hubbard, Ramesh K. Singh, Babuarao Kamble, Jeppe Kjaersgaard Apr 2011

Estimation Of Land Surface Evapotranspiration With A Satellite Remote Sensing Procedure, Ayse Kilic, Ian Ratcliffe, Pariskhit Ranade, Kenneth Hubbard, Ramesh K. Singh, Babuarao Kamble, Jeppe Kjaersgaard

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

There are various methods available for estimating magnitude and trends of evapotranspiration. Bowen ratio energy balance system and eddy correlation techniques offer powerful alternatives for measuring land surface evapotranspiration. In spite of the elegance, high accuracy, and theoretical attractions of these techniques for measuring evapotranspiration, their practical use over large areas can be limited due to the number of sites needed and the related expense. Application of evapotranspiration mapping from satellite measurements can overcome the limitations. The objective of this study was to utilize the METRICTM (Mapping Evapotranspiration at High Resolution using Internalized Calibration) model in Great Plains environmental …


Nir-Red Reflectance-Based Algorithms For Chlorophyll-A Estimation In Mesotrophic Inland And Coastal Waters: Lake Kinneret Case Study, Yosef Z. Yacobi, Wesley Moses, Semion Kaganovsky, Benayahu Sulimani, Bryan Leavitt, Anatoly A. Gitelson Mar 2011

Nir-Red Reflectance-Based Algorithms For Chlorophyll-A Estimation In Mesotrophic Inland And Coastal Waters: Lake Kinneret Case Study, Yosef Z. Yacobi, Wesley Moses, Semion Kaganovsky, Benayahu Sulimani, Bryan Leavitt, Anatoly A. Gitelson

School of Natural Resources: Faculty Publications

A variety of models have been developed for estimating chlorophyll-a (Chl-a) concentration in turbid and productive waters. All are based on optical information in a few spectral bands in the red and near-infra-red regions of the electromagnetic spectrum. The wavelength locations in the models used were meticulously tuned to provide the highest sensitivity to the presence of Chl-a and minimal sensitivity to other constituents in water. But the caveat in these models is the need for recurrent parameterization and calibration due to changes in the biophysical characteristics of water based on the location and/or time of the year. In this …

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.

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.

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 …

United States Geological Survey: Water Reports and Publications

The High Plains aquifer, underlying almost 112 million acres in the central United States, is one of the largest aquifers in the Nation. It is the primary water supply for drinking water, irrigation, animal production, and industry in the region. Expansion of irrigated agriculture throughout the past 60 years has helped make the High Plains one of the most productive agricultural regions in the Nation. Extensive withdrawals of groundwater for irrigation have caused water-level declines in many parts of the aquifer and increased concerns about the long-term sustainability of the aquifer.

Quantification of water-budget components is a prerequisite for effective …

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 …
