Hyporheic Flow Possibilities Within Lamprey (Petromyzon Marinus) Redds On The Blackledge River In Marlborough Connecticut, Samuel Fixler

Environmental Studies Honors Papers

The fluvial geomorphic process of hyporheic flow provides critical nutrients and dissolved oxygen to macroinvertebrates and eggs within riverbeds through hyporheic exchange. Hyporheic flow may operate at similar scales within sea lamprey (Petromyzon marinus) redds. Limited documentation exists on the hyporheic processes within lamprey redds. This study attempts to measure hyporheic flow using a saline injection syringe and salinity probe to record salinity-time curves. The method was applied to several redds on the Blackledge River, Marlborough, Connecticut. The second aspect of this study examined the hydraulic properties of lamprey redds within a controlled environment in a 0.5 m …

Malta : Natural Freshwater Resources, Lisamarie Pereira

Global Public Health

The aim of this paper is to discuss Malta’s struggle with limited natural freshwater resources. Malta currently uses aquifers to obtain natural freshwater. For over a decade, aquifers have been under pressure from over-abstraction. Due to this issue, Malta has not been able to obtain enough natural freshwater for agriculture and basic living. The biggest risk due to over-abstraction is retrieving a smaller volume of freshwater. In Malta’s attempted interventions, the biggest issue is the Maltese government’s misconceptions. The Maltese government believes the country has unlimited natural freshwater resources. Due to this misconception, nothing is being done to actively fix …

How To Collect Your Water Sample And Interpret The Results For The Poultry Analytical Package, Bradley J. Austin, Josh B. Payne, Susan E. Watkins, Mike Daniels, Brian E. Haggard

Arkansas Water Resource Center Fact Sheets

Rapidly growing birds may consume up to twice as much water as feed (Scantling and Watkins 2013), which means a plentiful supply of clean water is crucial for poultry health and productivity. To determine the quality of your poultry’s water resources, periodic sampling and analysis is needed. Analyzing water supplies can also be a crucial tool in identifying existing or potential challenges. The Arkansas Water Resources Center (AWRC) in cooperation with the UA Cooperative Extension Service offers several analytical packages to assess the quality of your water resources. This document is intended to provide guidance to poultry producers on collecting …

A Model-Based Assessment Of Potential Impacts Of Man-Made Reservoirs On Precipitation, Jesse Winchester, Rezaul Mahmood, William Rodgers, Faisal Hossain, Eric Rappin, Joshua D. Durkee, Themis Chronis

High Plains Regional Climate Center: Staff Publications

Land-use land-cover change (LULCC) plays an important role in weather and climate systems. Human modifications of land cover include building reservoirs and thus creating artificial lakes for multipurpose use. In this research, the authors have completed a Weather Research and Forecasting (WRF) Model–based assessment of impacts of two large parallel lakes on precipitation. This area is located in the western part of the states of Kentucky and Tennessee and known as the Land between the Lakes (LBL). To determine the impacts, this study has replaced the lakes with grass, deciduous forests, and bare soil and conducted model simulations for three …

The Effect Of The Dry Line And Convective Initiation On Drought Evolution Over Oklahoma During The 2011 Drought, Paul X. Flanagan, Jeffrey B. Basara, Bradley G. Illston, Jason A. Otkin

High Plains Regional Climate Center: Staff Publications

Observations from the Oklahoma Mesonet and high resolution Weather Research and Forecasting model simulations were used to evaluate the effect that the dry line and large-scale atmospheric patterns had on drought evolution during 2011. Mesonet observations showed that a “dry” and “wet” pattern developed across Oklahoma due to anomalous atmospheric patterns. The location of the dry line varied due to this “dry” and “wet” pattern, with the average dry line location around 1.5∘ longitude further to the east than climatology.Model simulations were used to further quantify the impact of variable surface conditions on dry line evolution and convective initiation (CI) …

Compensatory Response Of Fathead Minnow Larvae Following A Pulsed In-Situ Exposure To A Seasonal Agricultural Runoff Event, Jonathan M. Ali, John Sangster, Daniel D. Snow, Shannon L. Bartelt-Hunt, Alan S. Kolok

Nebraska Water Center: Faculty Publications

Agriculturally-dominated waterways such as those found throughout the Midwestern United States often experience seasonal pulses of agrichemical contaminants which pose a potential hazard to aquatic organisms at varying life stages. The objective of this study was to characterize the developmental plasticity of fathead minnow larvae in a natural environment subject to a seasonal episodic perturbation in the form of a complex mixture of agricultural stressors. Fathead minnow larvae were maintained at the Elkhorn River Research Station for a 28-d in situ exposure to an agrichemical pulse event.Minnow larvae were sampled after 14 and 28 days to characterize developmental plasticity through …

Water–Soil–Vegetation Dynamic Interactions In Changing Climate, Xixi Wang, Xuefeng Chu, Tingxi Liu, Xiangju Cheng, Rich Whittecar

Civil & Environmental Engineering Faculty Publications

Previous studies of land degradation, topsoil erosion, and hydrologic alteration typically focus on these subjects individually, missing important interrelationships among these important aspects of the Earth's system. However, an understanding of water–soil–vegetation dynamic interactions is needed to develop practical and effective solutions to sustain the globe's eco-environment and grassland agriculture, which depends on grasses, legumes, and other fodder or soil-building crops. This special issue is intended to be a platform for a discussion of the relevant scientific findings based on experimental and/or modeling studies. Its 12 peer-reviewed articles present data, novel analysis/modeling approaches, and convincing results of water–soil–vegetation interactions under …

Spatiotemporal Distribution Of Eutrophication In Lake Tai As Affected By Wind, Wenhui Zhang, Qiujin Xu, Xixi Wang, Xiaozhen Hu, Cheng Wang, Yan Pang, Yanbin Hu, Yang Zhao, Xiao Zhao

Civil & Environmental Engineering Faculty Publications

One common hypothesis is that wind can affect concentrations of nutrients (i.e., nitrogen and phosphorus) and chlorophyll-a (Chl-a) in shallow lakes. However, the tests of this hypothesis have yet to be conclusive in existing literature. The objective of this study was to use long-term data to examine how wind direction and wind speed affect the spatiotemporal variations of total nitrogen (TN), total phosphorus (TP) and Chl-a in Lake Tai, a typical shallow lake located in east China. The results indicated that the concentrations of nutrients and Chl-a tended to decrease from the northwest to the southeast of Lake Tai, with …

Developing A Hydrological Monitoring Program For Ponds In Wapusk National Park, Manitoba, Using Water Isotope Tracers, Stephanie Roy

Theses and Dissertations (Comprehensive)

Northern lake-rich landscapes are vulnerable to increases in surface air temperatures and are changing in dynamic ways. Current meteorological records indicate that some of the greatest warming in the past century has occurred in the Hudson Bay Lowlands (HBL). As the HBL is an extensive wetland consisting of hundreds of thousands of shallow lakes and ponds, it is difficult to anticipate the long-term implications that climate change will have on pond water balance. To develop and implement long-term monitoring of hydrological conditions, sampling of pond water isotope composition has occurred during the past six years in Wapusk National Park (WNP), …
