Underwater pipelines are often necessary to transport valuable resources between patches of land, and are expected to have increased utilization across the globe with the steep population increase on one hand, and unbalanced depletion of resources on the other. It is desirable to automate monitoring of various performance parameters associated with the pipelines through wireless sensor networks to ensure longevity of use and reduced running costs. However, such pipelines are not easily accessible, and are subject to harsh environments such as salt water and underwater currents. Therefore, an ideal node in this sort of network is embedded into the pipeline, and does not require batteries with regular replacement provisions. Using an energy harvester as the power source becomes a viable option. A method for near-optimal piezoelectric bimorph energy harvester module design is presented in this paper to enable a self-powered wireless sensor node for in-pipe monitoring using kinetic energy of water flow. A crude analytical model provides a starting point for the design, which is tuned through finite element modeling and simulation. Recently constructed Turkey-Cyprus water pipeline project is considered as a realistic application for determining boundary conditions. With an average water velocity of 1.4 m/s, the designed energy harvester is scalable to produce power between 820 mu W (single) to 12.3 mW (15 in parallel) with a negligible impact of 1.5 mm additional head loss. The method developed to deliver a finely modeled, scalable harvester design with minimum quantified impact to pipe performance is first of its kind to our knowledge.

Comparison of Frequency Analysis with Density Based Clustering in Evaluating Extreme Streamflows Kentel Erdoğan, Elçin(2018-12-31) Analysis of streamflow data has significant importance concerning sustainable use of water resources, planning supply of short and long term demands. Streamflow, unlike many other completely random variables, is a dependent variable which is closely related to both meteorological (such as precipitation, temperature) and catchment characteristics (such as land use and soil type). Thus inter-dependencies should be taken into consideration while analyzing streamflow. Besides this, while analyzing streamflow da...
Engineering Properties of Basalt Fiber-Reinforced Bottom Ash Cement Paste Composites Hanafi, Mohamad; Aydin, Ertug; Ekinci, Abdullah (MDPI AG, 2020-4-21) <jats:p>Extinction of natural resources builds up pressure on governments to invest in research to find more sustainable resources within the construction sector. Earlier studies on mortar and concrete show that bottom ash and basalt fiber are independently alternative binders in the concrete sector. This study aims to use bottom ash and basalt fiber blends as alternative novel-based composites in pure cement paste. The strength and durability properties of two different percentages of bottom ash (40% and 5...
Fuzzy vulnerability assessment model of coastal areas to sea level rise Özyurt, Gülizar; Ergin, Ayşen; Department of Civil Engineering (2010) Climate change and anticipated impacts of sea level rise such as increased coastal erosion, inundation, flooding due to storm surges and salt water intrusion to freshwater resources will affect all the countries but mostly small island countries of oceans and low-lying lands along coastlines. Turkey having 8333 km of coastline including physically, ecologically and socio-economically important low-lying deltas should also prepare for the impacts of sea level rise as well as other impacts of climate change w...
Energy harvester design method to power wireless sensor nodes for in pipe monitoring applications Qureshi, Fassahat Ullah; Muhtaroğlu, Ali; Sustainable Environment and Energy Systems (2016-7) A sensor network, used to monitor water, oil or gas pipelines, consists of a group of wireless sensor nodes (WSN) that are linked using a communication infrastructure. Traditional batteries are commonly used to power sensor nodes, but they have limited lifetime and require regular maintenance. Thus, their utility is limited in locations that are difficult to access, such as underwater pipelines. Therefore, using an energy harvester to power the sensor node becomes a desirable option. A method for near-...
Combined simulation-optimization of a coastal aquifer by using Genetic Algorithm Demirbaş, Kerim; Altan Sakarya, Ayşe Burcu; Onder, H. (2010-06-25) Excessive pumping in coastal aquifers results in seawater intrusion where optimal and efficient planning is essential. In this study, numerical solution of single potential solution by Strack (1976) is combined with Genetic Algorithm (GA) to optimize the maximum benefit in a coastal aquifer. Injection wells are added as an artificial recharge to prevent seawater intrusion. The objective is to optimize both pumping rates and locations of injection wells. The model is applied to a previous work by Mantoglou (...
