Numerical modeling of seawater groundwater relationships in the Selçuk sub basın, İzmir Turkey
Hassan, Abubakr; Çamur, Mehmet Zeki; Department of Geological Engineering (2004)
Seawater-fresh groundwater natural equilibrium conditions in the aquifers of the Selçuk sub-basin may be disturbed by the discharge occurred during the past 30 years in order to supply water for irrigation and domestic purpose usage. Two dimensional density dependent cross sectional saturated flow and solute transport simulations were carried out to determine whether seawater intrusion has occurred in the Selçuk sub-basin due to the imposed discharge or the determined salt-water in the western section of th...
Effects of precipitation recharge and artificial discharge on salt water-fresh water interface movement in selçuk sub-basin: climatic indications
Aykanat, Gökben; Çamur, Mehmet Zeki; Department of Geological Engineering (2011)
Fluctuations in temperature and precipitation amounts due to climate change influence recharge rate of groundwater. Any variations in the amount of precipitation recharge and artificial discharge directly affect groundwater level and so the salt water intrusion rate in the aquifers, which are in contact with sea water. The purpose of this study is to determine the overall historical precipitation recharge trend in Selçuk sub-basin and to detect whether there is a decrease or increase in recharge amounts due...
Investigation of waterhammer problems in the penstocks of small hydropower plants
Çalamak, Melih; Bozkuş, Zafer; Department of Civil Engineering (2010)
Waterhammer is an unsteady hydraulic problem which is commonly found in closed conduits of hydropower plants, water distribution networks and liquid pipeline systems. Due to either a malfunction of the system or inadequate operation conditions, pipeline may collapse or burst erratically resulting in substantial damages, and human losses in some cases. In this thesis, time dependent flow situations in the penstocks of small hydropower plants are investigated. A software, HAMMER, that utilizes method of chara...

Adaptive control of guided missiles
Tiryaki Kutluay, Kadriye; Yavrucuk, İlkay; Department of Aerospace Engineering (2011)
This thesis presents applications and an analysis of various adaptive control augmentation schemes to various baseline flight control systems of an air to ground guided missile. The missile model used in this research has aerodynamic control surfaces on its tail section. The missile is desired to make skid to turn maneuvers by following acceleration commands in the pitch and yaw axis, and by keeping zero roll attitude. First, a linear quadratic regulator baseline autopilot is designed for the control of the...
