Fluvial Erosion Impacts on Infrastructure Along Indiana Rivers and Streams

Rivers provide for storm water drainage, municipal water usage, and recreation, and they add to the natural aesthetics of a community. As we encroach on river corridors, flooding and damage due to streambank erosion endangers our built environment. In this session we use the recently completed White Lick Creek System Assessment in Hendricks County as a case study to discuss the importance of understanding system-wide stream evolution and movement processes in evaluating and addressing impacts on infrastructures along Indiana streams

Fluvial Erosion Hazard Mitigation

Fluvial erosion—erosion that occurs along a river—is a major threat to infrastructure, and most commonly to roads. This presentation provides an overview of the Indiana Fluvial Erosion Hazard Mitigation Manual, which was recently developed on behalf of the Indiana Silver Jackets. The manual provides a framework for analyzing, designing, and post-construction management / maintenance for fluvial erosion hazard mitigation projects in Indiana

Tick Ectoparasites of Animals in Borderline of Iran-Iraq and Their Role on Disease Transmission

Background: Since ticks are potent vectors of various diseases, identification of these species are clinically important to protect the public health and control veterinary problems in the communities. We aimed to figure out the frequency of ticks on cows, goats, sheep, lambs, turtles and also obscure hosts in Kurdistan Province, bordered with Iraq June 2012 to May 2013. Methods: The hosts were selected randomly and examined individually for tick infestation. In case of infestation, ticks were collected using forceps and then preserved in 70% ethyl alcohol. All collected specimens were preserved in tubes and relative information was recorded and then identified based on morphological characteristics. Results: Totally, 1209 ticks were collected. The prevalence of ticks on cows, sheep, goats, lambs, turtles, poultry and obscure hosts was 11.33%, 55.41%, 6.53%, 5.95%, 0.9%, 8.02% and 11.82% respectively. The mean number of ticks on each animal was 1.6. Number of 5 genera, including Rhipicephalus, Argas, Ornithodoros, Hyalomma and Haem­aphysalis and 9 species; including R. sanguineus (60.05%), R. bursa (0.08), Hy. anatolicum (12.33), Hy. asiaticum (1.49), Hy. aegyptium (0.91), Hy. marginatum (0.08), Haemaphysalis parva (4.22), Hyalomma sp. (0.99), Orni­thodoros lahorensis (11.83), and Argas persicus (8.02) were identified. Conclusion: The most abundant species in this study area was Rh. sanguineus (60.05%). Due to high prevalence of tick specimens and a variety of collected species from sheep (55.41%), the vaccination of sheep and control of tick vectors are recommended
