Service-Learning In Action: Lafayette, Indiana, Rain Garden Installation, Elizabeth Mccleery
Purdue Journal of Service-Learning and International Engagement
Indiana’s Wabash River is being polluted with contaminated water runoff from precipitation events. A lack of pervious land cover has led to an accumulation of fertilizer, sediment, and waste in the river. Green infrastructure, a stormwater management practice that mimics the natural ecosystem, is one of the most effective ways to prevent pollution from stormwater runoff and benefit the community. This project consisted of a rain garden installation at the Lafayette Fueling Station, a site where frequent water drainage and water runoff into the Wabash occurs. The rain garden will allow on-site water infiltration during rain events and promote natural …

Permeability is a soil parameter related to the construction industry to understand the processes of infiltration, runoff, and settlement. The risk of testing errors is inevitable in permeability investigations, especially in expansive soils. Trial and error in permeability testing becomes difficult due to soils with small pore sizes and large shrinkage expansion. Several studies related to soil physical properties that affect permeability have been conducted. However, the correlation results obtained still have poor accuracy. Artificial neural networks (ANN) are machine learning systems that can change their structure to solve problems that are included in the system. The use of ANNs …

Improving Square Skirted Foundations Behavior On Sand, Tamer Al-Shyoukhi, Ayman Altahrany, Mahmoud Elmeligy
Mansoura Engineering Journal
Shallow foundations' behavior is enhanced by using skirts to confine the soil beneath the foundation. The bearing capacity and settlement of skirted foundations resting on the sand are influenced by the size of the skirt cell and shear strength of sand. Experimental modelling was carried out on an axially square-skirted footing resting on sand in this study. Plaxis-3D software was used for numerical analysis to support the experimental results. The numerical analysis results validated the experimental results. The outcomes of the study demonstrated that skirts wider than the footing size increased the bearing capacity of skirted foundations. In the case …
Hawai'i Wildlife Fund V. County Of Maui, Lowell J. Chandler
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 …
