Chapter 9 Baseflow seperation

[@Jet-rx1ji]

This is better than the 3rd year hydrology course I pay thousands for. I wish I had found this sooner. Thanks so much..

[@嗯加油]

You saved my assignemnt and exam. Thank you so much!! (Dead Serious)

[@ajjones7295]

Your videos are incredibly helpful. Thank you so much!!

Can we just appreciate the handwriting 😍

For the data given below, a) Calculate the runoff coefficient for this storm event, by first separating the base-flow using the log Q - time method. b) Calculate the basin lag time (by finding the time difference between the centroid of the rainfall data and the peak of the surface runoff hydro-graph). TIME (hours) 0 3 6 9 12 15 18 21 24 27 FLOW (cumecs) 5.0 3.0 2.0 5.7 12.1 8.1 5.3 4.0 3.1 2.7 RAINFALL (mm) 0.0 6.0 10.0 9.0 4.0 2.0 0.0 0.0 0.0 0.0

Since the time step is 1 hour, shall we multiply the direct runoff by 1 hour?

[@muhammadzeeshan1752]

Good work mam..

[@alvinmaliakal6314]

Why did you multiply the direct runoff by 2 hrs? Could also multiply it by 1 hr? ..also awesome video

[@Mr0132456789]

yes .. you must multiply by 1 Hr

[@yishakabrham5002]

yes by 1 hr

[@brennicolas4885]

what base flow method did you used ma'am ?

[@samuelnimax1551]

If between 3-4 hours there is no rain. How does that affect the calculation?

[@mther123]

You have good knowledge

[@TokaallahAbdelwahab--]

Excellent and simple :D

[@kobietroipatino8900]

may i know why time isn't in days? or it just wont matter?

[@akshayhamde8554]

Hlo mam.. I didn't understand how did u find that Vdr... Can u explain more. Plz...

[@faridoondanesh1655]

this is a simple area method calculation. the average height x base (triangle figure).

[@MsFVee]

how did u get the value of 90 for the 1st hr base flow

[@seemashah-fairbank2760]

In base flow separation you start a hour zero and find the lowest value. It is assumed that until the hydrograph starts to rise the flow is considered to be base flow.

[@seemashah-fairbank2760]

typo should be 1hr

[@celinkosixolani7873]

On direct runoff madam, why did you divide by 2, and also why did you multiply by 2hrs each discharge.

[@ruffneck168]

@@celinkosixolani7873 i need to know this too

[@hmarmac2347]

I thought this is a bass lesson

[@akshayhamde8554]

Mam may I know your Email to know more.
