Fine Sediment Modeling During Storm-Based Events In The River Bandon, Ireland, Juan T. Garcia, Joseph R. Harrington

Publications

The River Bandon located in County Cork (Ireland) has been time-continuously monitored by turbidity probes, as well as automatic and manual suspended sediment sampling. The current work evaluates three different models used to estimate the fine sediment concentration during storm-based events over a period of one year. The modeled suspended sediment concentration is compared with that measured at an event scale. Uncertainty indices are calculated and compared with those presented in the bibliography. An empirically-based model was used as a reference, as this model has been previously applied to evaluate sediment behavior over the same time period in the River …

Evaluating E. Coli Particle Attachment And The Impact On Transport During High Flows, Louis Amegbletor

Electronic Theses and Dissertations

Fecal indicator bacteria, including E. coli, are the leading cause of water quality impairments within assessed waters in the United States. The source of E. coli includes WWTP, leaking sewers, animal manure, wildlife, livestock, and stream bed sediment. Storm events contribute to bacteria loading within waters through wash-in of land sources of bacteria and resuspension of bacteria within sediments. Bacteria introduced into the water column are either attached to particles or are unattached (or free-living). The goal of this study was to examine the attachment of E. coli to different particle sizes, including their impact on contributing to water …

Changes In Heavy Rainstorm Characteristics With Time And Temperature, Barry A. Palynchuk Phd, Yiping Guo Phd

Barry A. Palynchuk PhD

The effects of climate change upon extreme rainfall is evaluated, based upon the identification of individual storms, and the changes in their statistical parameters and distributions. Those changes will be measured based upon historical time spans, and climatic temperature associated with the events. A brief review and comparison with other research is provided.

From Gananoque Reporter Extensive damage to properties in Gananoque

An unconfirmed tornado touched down here in Gananoque. Most of the damage was confined to River, Fourth, Oak Streets and Victoria Ave.

Most of the damage was to trees. Several trees in the narrow path were damaged between Garfield and Victoria. In general, young trees with a diameter of under 1ft were uprooted, larger trees, diameter greater than 1.5ft, appeared snapped off about halfway up. The snapped off tree tops appear to have caused a significant portion of the roof damage in the area. It appeared that only two or three houses sustained roof damage directly tied to the tornado. The uprooted/snapped off trees gave us the best indication of convergence and in one instance, we actually have two trees, on opposite …

Massive Spatiotemporal Watershed Hydrological Storm Event Response Model (Mhserm) With Time-Lapsed Nexrad Radar Feed, Changqing Song

Civil & Environmental Engineering Theses & Dissertations

Correctly and efficiently estimating hydrological responses corresponding to a specific storm event at the streams in a watershed is the main goal of any sound water resource management strategy. Methods for calculating a stream flow hydrograph at the selected streams typically require a great deal of spatial and temporal watershed data such as geomorphological data, soil survey, landcover, precipitation data, and stream network information to name a few. However, extracting and preprocessing such data for estimation and analysis is a hugely time-consuming task, especially for a watershed with hundreds of streams and lakes and complicated landcover and soil characteristics. To …
