Water hammer is an unsteady hydraulic problem commonly found in closed conduits of hydropower plants, water distribution networks, and liquid pipeline systems. Because of either a malfunction of a system or inadequate operation conditions, a pipeline may collapse or burst erratically, resulting in substantial damages and human loss in some cases. Therefore, it is crucial that engineers design and/or analyze projects with reliable computing methods for all foreseeable operation situations. In this paper, transient flow situations in run-of-river plants are investigated for various operation conditions such as load rejection, load acceptance, and instant load rejection. A computer program using the method of characteristics is used in two case studies having Pelton and Francis turbines, respectively. On the basis of the field data of the plants, their computational models are set up, and resulting transient pressures are computed and compared with available measured pressures. Comparisons indicate that the mathematical model predicts the measured pressures closely for all simulations.

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...
Renovation of a safety-inspection methodology for river bridges
Yanmaz, Ali Melih; Caner, Alp (American Society of Civil Engineers (ASCE), 2007-09-21)
River bridges and related infrastructural elements need to be monitored and inspected periodically for deterioration and loss of function due to aging, adverse hydraulic conditions, and chemical attacks. Necessary protective works and related actions should then be implemented to increase safety. Types of items to be inspected would be categorized as structural, geotechnical, hydraulic, and structural material conditions. Requirements for periodic inspections and the ways of handling these activities were d...
Performance Evaluation of Internal Drains of Earthen Dams
Çalamak, Melih; Yanmaz, Ali Melih (American Society of Civil Engineers (ASCE), 2018-12-01)
Seepage is always expected in earthen dams because they are made of porous materials. However, it should be always under control and its amount and pore-water pressures should be kept below acceptable limits. This can be satisfied by installing internal drains. This study reviews the characteristics of blanket, chimney, and toe drains and assesses their suitability and effectiveness for various material types and geometric characteristics in separate cases. Numerical simulations are conducted for steady-sta...
Seismic Performance Assessment of Masonry Buildings Using In Situ Material Properties
Cobanoglu, Baran; ALDEMİR, ALPER; Demirel, Ismail Ozan; Binici, Barış; Canbay, Erdem; Yakut, Ahmet (American Society of Civil Engineers (ASCE), 2017-08-01)
Seismic performance assessment of existing buildings requires the existing material's properties to be determined as this has a significant influence on the seismic risk. As one of the most common construction type in Turkey, masonry buildings are assessed generally based on the recommended material properties specified in relevant codes as opposed to testing of samples taken from the existing buildings. However, due to different material types and workmanship quality, the specified properties might be quit...
Method for energy performance integration in corporate public real estate management
Gürsel Dino, İpek; SARİYİLDİZ, Sevil; Stouffs, Rudi (American Society of Civil Engineers (ASCE), 2014-04-01)
Building-performance assessment is receiving increased attention within the building industry because of the European Union's (EU's) targets to improve energy efficiency and to increase the use of renewable energy technologies. In this context, there is great emphasis placed on the existing building stock as having a huge environmental impact. The continuous assessment of the energy performance of existing buildings comes into focus to ensure the intended performance and operation during the building life c...
