The project will study the effects of large debris flows in the Cheekye River using simple and low cost physical models, which could be used to study a wide range of problems in geomorphology and river engineering in the future. Here, we will test their performance and write guidelines for their application in BGCs steep creek assessments.
Infiltration facilities are an effective storm water management practice. The conventional continuous simulation models are widely used in the hydrologic analysis of infiltration facilities in practical engineering practices. However, these continuous simulation models are often time-consuming and data-demanding.
Vibrant coral reefs are amongst the worlds most diverse and economically important marine ecosystems, but are also imminently threatened by climate change and local threats, including fishing and pollution. Understanding how these threats impact coral reefs, and the capacity for reefs to recover after bleaching events is critically important. This project will focus on Kiritimati (Christmas Island), a natural laboratory in the equatorial Pacific Ocean, which experienced extensive coral bleaching during a recent intense heat wave.
This project will deal with the detection, the fractionation and the quantification of selenium in its many forms (elemental form or in the form of selenide (Se2-), selenate (SeO4 2-), or selenite (SeO3 2-)) in mining waters. Dissolved and total recoverable Se will be quantified by inductively coupled plasma mass spectrometry (ICP-MS). Quantitative Se speciation will be conducted using high performance liquid chromatography (HPLC) coupled with ICP-MS to allow the assessment of bioavailability of selenite and selenate in different plant-soil systems by sequential extraction.
Although rare, industrial facilities can suffer from minor to catastrophic failures, commonly referred to as loss of primary containment (LOPC), which can result in the release of hazardous gases and/or liquids. In order to protect the safety of the public, companies must provide a means of mitigating the potential damage to people and the environment.
Forest companies would like to reduce the number of birds, eggs, and nests that are negatively affected by logging. They are particularly interested in reducing impacts on species at risk. The problem is that we dont have detailed knowledge of where every bird lives, so its difficult to make educated choices about where and how much forest to harvest. This research will help provide a solution to this problem. We can relate bird data to landscape and forest characteristics like elevation, forest age, and forest height to understand which forest types have the most birds.
In this project, a pre-conditioning system to remove the oxygen prior to reaching a bioelectrode system sensor will be developed and tested. Bioelectrode system sensors require anoxic conditions for operation, and a low complexity solution would extend use cases of the technology. Bioelectrode system sensors measures the microbial activity of bacteria and the data can be used to optimize treatment efficiency, detect deleterious substances, and quantify Biological Oxygen Demand.
Glacial Isostatic Adjustment (GIA), also known as Postglacial Rebound, describes how the Earth responds to different loading/unloading processes, through deformation and vertical motion. One important loading/unloading process includes the Wisconsinan Glaciation Episode and the last glacial maximum, approximately 21ka BP. The unloading processes since led to vertical motion centered around James Bay/Hudson Bay, Canada, with uplift rates up to 12 mm per year. The spatial distribution of vertical motion differs which leads to differential vertical motion of the Earth surface.
When waste rocks generated by mining activities are exposed to the air and water, various toxic elements may be released to receiving waters and soils. Arsenic (As) is known as one of the most toxic pollutants which can cause damage to the environment and human health. To implement effective source control, it is essential to identify key factors that control the leaching process. The main objective of this research is to determine the rate-controlling steps in the release of toxic elements, with the initial focus on arsenic release.
The main goal of this research project is to develop an inexpensive multifunctional filtering medium for purifying contaminated drinking water using modified Canadian natural zeolite with different metal elements such as zinc, copper and silver. In this project, a filter material will be developed which has the ability to kill bacteria from drinking water sources. This filter will also be useful for removal of toxic heavy metals from contaminated drinking water.
