Hydrogeology 101: Groundwater exploration strategy

In this video I will discuss my preferred groundwater exploration strategy, which divides a project up into four separate phases:
Phase 1: Desk study and baseline survey
Phase 2: Geophysical survey
Phase 3: Exploratory drilling and pumping tests
Phase 4: Groundwater exploration report
At the end of phases 1 & 2 you decide to either stop the project, continue with caution or to go ahead. This reduces the risk of wasting time and money on unsuccessful wells. We will look at some examples from projects in Mali, Afghanistan, Pakistan and Ghana.

This is an educational video & part of the Hydrogeology 101 course.

thanks sir useful for baseline survey

[samuelbakasa]

Great content very insightful and explained beautifully

[mamadoudiaby]

Am Diaby From Mali, completing my master in engineering geology in Malaysia. I find your content extremely helpful
keep up the good work

[mostafaismail]

Very generous sharing this knowledge. I have learnt a lot. Thank you.

[annagravina]

How did you break into gw well installation in Africa? These videos are super helpful for me as a junior geologist in environmental consulting!! Keep up the good work!

[hajaraibrahim]

Interesting and educating I want manual to go through for knowledge tnx.

Thanks Andreas. I have a MSc in surface hydrology and remote sensing. I am self-learning groundwater hydrology and soon want to be a hydrogeologist. I have a solid knowledge in GIS, Hydrology, Hydroclimatology.


I want to fill a gap in my country Somaliland where it's hard to find a knowledgeable and experienced hydrogeologist. About 6 out of 10 drilled wells fail during the pumping test because of very poor geophysical survey and they skip the desk and baseline studies. Those people who do such poor geophysical survey have only geology background.

Would I be a good hydrogeologist soon?

Can hydrogeoligist do all the phases of groundwater exploration including the geophysical survey?

Hello Mr Andreas, thanks for these extremely valuable tutorials. I have a question regarding to the pumping tests that you mentioned in here. How do we actually interpret the recharge zones based on a pumping test result like a constant discharge test curve? I have heard this in a couple of places, but is it actually possible to delineate such information like this area must be a inflow boundary, this area must be a no flow boundary and so on, only based on the pumping test?
Really appreciate if you could let us know your thoughts on this. Thanks for the amazing work again :)

Thanks...it was very informative... but what if want to drill a well on a private land, I mean is it the same steps or more or less?
So you're restricted to a limited area on your land...what's the best tools available for decrease odds of failure?

Informative video, I'm from Ghana. Will also like to know the opportunities in this field if one specialises.

[ramonbaccomperi]

please how many groundwater assessment methods do we have? if you can list some or refer me to link where i can get them. thank you

[NaqibullahKargar]

Thank you !, very useful and informative !

[nickpiscopo]

What resistivity testing equipment are you using for the geophysical survey? Thank you

[oubiradjihane]

thanks sir, Can u explain the important steps of modeling ?

[sinkymanku]

Please explain all methods of ground water exploration

[anaspatel]

Sir i have a one question
How to do course of ground water exploration
Is there any certificate course available plz reply I am trying to do this 👌

[gmallikarjunaswamy]

Please do more videos on hydrogeology.

[Rahulkumar-zktf]

Upto how much depth we can detect ground water ?

[MrOrdaaye]

Which underground water detector do you advice? Thank you

[osamakh]

Thank you sir, your videos are really useful and helpful.
