Thanks Isaac. It helps me clarify my confusion about time of concentration and td. Also it helps me solve problems about discharge calculation with mult-catchment. Thank you very much.
Issac, in your lecture about aquifer, you mentioned 1 wellpoint dewatering. How about when there are 2 wellpoints for deeper dewatering calculation? How may we know how to solve those kind of calculation like finding drawdown, pump rate, etc. Thank you very much for your in-depth teaching. Best wishes from Hong Kong.
@@fn15895 The principle of superposition applies in cases of multiple wells. None of my videos or examples include multiple well problems, but there is an example in the book "Water-Resources Engineering" (3rd edition) by David A. Chin. ISBN: 978-0-13-283321-9. See pages 741 to 744.
@@IsaacWait I just discover my university library has this book. I will read it tomorrow to see whether it can help me understand. Really thank you very much for your selfless help. Thank you.😊
Thanks Isaac WAIT. It helps me to clarify discharge calculation, I am very appreciate with the excel sheet template, could you send for learning purpose ,I remain your kindly student
Thank you for this video! It explains the concept and the processes I need to do a similar set of calculations!
Glad it is helpful. Good luck!

Thank you! i have one question. Why is the slope not considered in getting the velocity?
It is considered in the re arranged Manning Equation.
hello sir. could you further explain where did the mD=2.16 came from?
Manning's equation for BG units, rearranged in terms of unknown pipe diameter, D.
