Thank you for the correction

The "periodic settling theory" refers to the process and design considerations intended at effectively managing sedimentation in the Settling basin. A settling basin is a structure used to remove sediment from the water before it enters the waterways, such as Forebay, pipes, surge tank, turbines, to prevent damage and ensure efficient operation. Key Aspects of Periodic Settling Theory in a Settling Basin: 1. Periodic Nature of Settling: The term "periodic" implies that the settling process is not continuous but occurs at regular intervals. This could be due to variations in water flow, sediment load, or operational procedures. For example, during periods of high water flow, more sediment might be carried into the basin, requiring more frequent settling and cleaning. 2. Sediment Transport and Deposition: Water entering the settling basin often carries sediment, including sand, silt, and other particles. The theory focuses on how these particles settle out of the water as it flows through the basin. Larger, heavier particles tend to settle more quickly, while finer particles may remain suspended longer. 3. Design Considerations: The design of the settling basin is influenced by the periodic settling theory. Considering factors like basin length, depth, and flow velocity to optimize the settling process. The goal is to ensure that the water velocity is low enough for sediment to settle out before the water exits the basin. It helps in determining the timing for maintenance activities, such as the removal of accumulated sediment. Regular intervals for sediment removal are planned to prevent excessive build-up, which could reduce the effectiveness of the basin. 4. Operational Management: Periodic settling theory helps in the operational management of the basin which involves in monitoring sediment levels and adjusting the operation of the basin to maintain its efficiency. For example, in some designs, water flow can be temporarily slowed or even stopped to allow more complete sedimentation. Importance in Hydropower Projects:  Turbine Protection: Effective sediment management in the settling basin protects the turbines and other downstream equipment from abrasion and damage caused by sediment-laden water.  Operational Efficiency: By ensuring that sediment is periodically settled and removed, the settling basin helps maintain the efficiency of the hydropower plant, reducing the need for costly repairs and prolonging the life of the equipment.  Environmental Impact: Proper management of sediment also helps minimize the environmental impact at the downstream section, as excessive sediment can harm aquatic habitats and alter river morphology.

Thank You!

Its in Nepal

We too haven't had any proper books but have taken some ideas from published papers like www.researchgate.net/publication/313242728_Surge_Tank_Design_Considerations_for_Controlling_Water_Hammer_Effects_at_Hydro-electric_Power_Plants, www.researchgate.net/publication/326345663_Optimizing_surge_tank_layout_for_highly_flexible_hydropower you can have a look on them

Lets connect and talk on our instagram/ messenger or in email. As provided in our pages

@@HydropowerExplorers I have sent you the mail which I have found on your page, please check it. thank you

Thank you for reaching out! I'll make sure to check my email.

😁😁

Why?

Thank you, Keep in touch with us, we will come again with one new project tour

We are from Nepal

For this question we have made another video with title "Derivation of Most Economic Trapezoidal Section" on link ruclips.net/video/qSgOedT_fLk/видео.html you can have a look on it.

The Side Slopes shall be assumed before the economic Perimeter Calculation. In case of canal design, the choice of slope is influenced by various factors such as the desired flow velocity, sediment transport by water, and the type of soil in the canal construction area. A slope that is too steep can lead to erosion and excessive sedimentation, while a slope that is too gentle may result in inadequate water flow. Here in our case the 1/2(H):1(V) ratio is a common slope used in trapezoidal canal designs as it balances these considerations, providing a reasonable compromise between efficient water flow and prevention of erosion.

Oh! Really, Thanx!

Oh! Really, Thanx!

Oh! Really, Thanx!

you mean, I need to create separate playlist videos only on "Pressure rise due to gradual closure of a valve" or separate playlist only for the all type solved Question ?

@@HydropowerExplorers I mean separate playlist for all solved questions, it will be much easier to navigate through your channel. Thnx!

@@keyable Some times it may not be possible to separate all the question as at present i am separating the playlist as per Hydropower, Hydraulics and Hydrology etc. but will try best

@@HydropowerExplorers Ok thanks!

We have created a Playlist as per your concern you can have a look on our play list sections.

for the reference you can refer Hydropower Engineering For SPPU B.E. Civil Engineering Sem 8 by B. L. Singhal, Hydropower Engineering by Edwin Parks, Hydropower from Small & Low-Head Hydro Technologies (Energy Science, Engineering and Technology)by Amanda E Niemi, Cory M Fincher, Technological Innovations and Advances in Hydropower Engineering by Yizi Shang, Ling Shang, Xiaofei Li, Hydropower Engineering Handbook by John Gulliver, Roger Arndt. you can also check out the Fundamentals of Hydropower Engineering by Er.

Recently we have uploaded a video on the surge tank, you can have a look. And for the pressure tank we will upload another video soon. keep on watching our channel, thank.

@@HydropowerExplorers Thanks looking forward for your new videos.
