I am really interested in major laws and aspects of hydraulics. I would like to investigate the usage of hydraulics in medicine. After having learnt about the application of artificial lungs airing machine (aids ventilation) and diaphragm compressors, I have seen the importance of hydraulics in medicine. But I am just a beginner, so it‘s so difficult for me to concretize the exact sphere of my future research. I hope I will define it during the first two years of study at our university.

This thesis describes research carried out to study steep streams. Step-pool sequences, a typical feature of such streams, were found to occur on every steep stream studied in the field. The most important control on the spacing of the steps was width. Flume experiments produced steps (at an average Froude number of 0.88), and showed that the presence of steps increased resistance to flow at lower than step-forming flow and decreased resistance at above step-forming flows. In the field, flow resistance was found to be controlled by sediment characteristics and the amount of step protrusion. Th

Abstract:

In recent years, magnitudes of flood estimates used in hydraulic design have increased for many reservoirs. Consequently, many existing spillways are now deficient as they do not meet current discharge capacity requirements. To rehabilitate existing, fixed-width spillways, labyrinth weirs are often viable solutions. For reservoir applications, arcing labyrinth weirs into the reservoir increases hydraulic efficiency. This results from better cycle orientation to the approaching flow field. This study supplements available arced labyrinth weir hydraulic data by observing flow characteristics of

The Amazon River is the largest by discharge and basin area globally, annually it delivers large volumes of water to the oceans through a mono modal flood cycle. During this cycle an unknown quantity of water is exchanged with the adjacent floodplain. The volume and duration of this exchange plays an important natural function for sedimentological, biogeochemical and ecological processes. It is known that hydraulic processes within the floodplain, including water depths, flow discharges and inundation timings, influence this exchange of water between the Amazon River and its floodplain.

Experimental physical model studies of hydraulic structures are often conducted to replicate flow behavior that may occur at the prototype scale. Geometric similitude is most often maintained between the prototype and model when studying reservoir and open channel hydraulic structures to account for the dominant gravity and inertia forces while other fluid forces (e.g., viscosity,surface tension) are assumed negligible. However, as model size and/or upstream head decreases, other fluid forces can exceed the negligible level and influence model flow behavior. This phenomenon is referred to as s

Linear weirs are a common hydraulic structure that have been used for centuries with many different applications. One characteristic of weirs that is particularly useful is the head-discharge relationship where the discharge over the weir is directly related to the upstream water depth above the crest. In general, the head-discharge relationship for a weir is determined experimentally in laboratories using geometrically similar models. Due to space, time, money, and discharge capacity limitations at water laboratories, creating full scale models is not always a feasible option when determining
