When The Well Runs Dry: Why Water-Rich States Need To Prepare For Climate Change And Protect Their Groundwater, Danielle Takacs Oct 2018

When The Well Runs Dry: Why Water-Rich States Need To Prepare For Climate Change And Protect Their Groundwater, Danielle Takacs

William & Mary Environmental Law and Policy Review

It may seem surprising to see such concern over groundwater usage in a state like Wisconsin. While known for its dairy and cheese production, Wisconsin is first in the nation for producing snap beans and cranberries. Agriculture contributes $88.3 billion annually to Wisconsin’s economy alone. In addition to bordering two of the Great Lakes, Lake Michigan and Lake Superior, Wisconsin boasts that it is home to about 15,000 lakes. And this does not include the numerous rivers and streams throughout the state. These facts alone may make Wisconsin seem an unlikely place for disputes over groundwater, as water seems to …

Creation Of A Numerical Mathematical Model Of Geofiltration Processes And Its Adaptation For Solving Epignosic And Forecast Problems (In Terms Of Gurlen District Of Khorezm Region), Tolkun Mirakhmedov Sep 2018

Creation Of A Numerical Mathematical Model Of Geofiltration Processes And Its Adaptation For Solving Epignosic And Forecast Problems (In Terms Of Gurlen District Of Khorezm Region), Tolkun Mirakhmedov

Bulletin of National University of Uzbekistan: Mathematics and Natural Sciences

The article considers the creation of a mathematical model of geofiltration processes in Gurlen District. Methods for calculating and developing a mathematical model and algorithms were carried out, and applied software was developed, and the developed geofiltration mathematical model was adapted to solve the epignosic and forecast problems of the area under consideration.

Tree Ring Disturbance Clustering For The Collapse Of Long Tree-Ring Chronologies, John Woodmorappe Jul 2018

Tree Ring Disturbance Clustering For The Collapse Of Long Tree-Ring Chronologies, John Woodmorappe

Proceedings of the International Conference on Creationism

The Disturbance-Clustering hypothesis, first introduced here, posits that geographically-demarcated subtly-perturbed tree rings had induced the affected trees to crossmatch not in accordance with climatic signals, as is assumed in conventional dendrochronology. They instead crossmatch only within a geographic cluster of like-perturbed trees, and not with those of other clusters or with any of the remaining unaffected climatically-governed trees. During chronology-building, these clusters became connected with each other, into an artificially-long chronology, by means of rarely-occurring fortuitously-crossmatching “bridge” series. An experiment involving fifteen ostensibly heterochronous ancient trees graphically supports this hypothesis. Merely one-per-decade individual-ring perturbations induce all fifteen series to form …

Hawai'i Wildlife Fund V. County Of Maui, Lowell J. Chandler Apr 2018

Hawai'i Wildlife Fund V. County Of Maui, Lowell J. Chandler

Public Land & Resources Law Review

In Hawai’i Wildlife Fund v. County of Maui, the Ninth Circuit held that the plain language of the Clean Water Act provides jurisdiction over indirect discharges of pollutants from a point source into groundwater that is shown to be connected to navigable waters. The court found that studies confirmed pollutants entering the Pacific Ocean were fairly traceable to the County of Maui’s sewage disposal wells. In affirming the district court’s ruling, the Ninth Circuit held that Maui County violated the Clean Water Act by discharging pollutants into a navigable water without the required permit. The court also concluded the …

Variation Of Groundwater Divides During Wet And Dry Years In The Wolf River Basin, Northeastern Wisconsin, Susan A. Borchardt Mar 2018

Variation Of Groundwater Divides During Wet And Dry Years In The Wolf River Basin, Northeastern Wisconsin, Susan A. Borchardt

International Journal of Geospatial and Environmental Research

Groundwater divides and surface-water divides do not always coincide, and groundwater divides are not as easy to detect as surface-water divides. Groundwater divides are also dynamic, moving in response to environmental and anthropogenic stresses. This study will investigate how different hydrological stresses can change the size and shape of the study basin and whether the stresses together mitigate or intensify the basin’s response. This study looks at three factors that may affect the size and shape of the Wolf River basin: annual precipitation, soil permeability, and the presence of high-capacity wells. This study examined four groundwater basins that represent the …
