Groundwater Flow Basics

[@garyromero3058]

Wish I found this video before I took my quiz... Damn dude, you explained this very well.

Many doubts in hydrogeology has cleared after watching this

[@jackdaniels9296]

Thank you for creating this video.

[@mohammadaasifkhaja1892]

respected sir i am highly motivated by your video lecture series. Thanks for shearing your precious knowledge with us. Sir i hv a question how can i delinate and define catchment aquifer practically or through some software to calculate all the hydrogeological properties of a catchment especially catchment transmissivity.

Hi, nice video, but acording to the image, the flow might be like a valey, there are two ranges on the limit of the image, so the direction would be more like the water movign to the center, well, we kown that the water movement could no be according to the topography, but its interesting. I didnt understan, did you take the information from a real work or the lines more for explanation?

[@gooddaniel8603]

Very well explanation, thank you

[@ganeshgowda3dgroundwatersu251]

nice job

[@chickboris8946]

Thanks for this video. Please I need the video that differentiates a confined from an unconfined aquifer

Can we get such map of our farm ? What are procedure

[@sab35263]

Great video, Dane! Have you ever used MicroFEM groundwater modeling program or any other groundwater modeling programs? would be really nice if you can do a video on that. Thanks again!

[@kyleuzumaki917]

Really helpful, thanks.

[@anitadewi4021]

Thanks for the info . Im trying to make a well on a solid limestone Island near Bali, Indonesia ,and trying to get the any info to better understand how aquifers work . Much appreciated

[@daneandersen8181]

What is the purpose of the well? For domestic supply? Usually, a drilling contractor is adequate to help you site your well location. If you require more water production, you will want to hire a professional geologist.

[@sangamsamal1685]

Sir why we always say that where the equipotential lines are closely spaced it will not a good aquifer and where the equipotential lines are widely spaced it shows a good aquifer presence?

[@laispereira5534]

Thank you!!

How to measure the water table depth in a well ?

[@jonathanrichardcotting5029]

the depth of water surface in the well after stabilization, might be interpreted as the water table depth

[@bernardrobenson5071]

Thanks for this video. However, does the GW moves from well to another as its direction above the earth specifically when we deal with confined aquifer.? Does it follow the same path based on gradient difference or is there any difference in water direction under ground which might be influenced by geological formations?

You probably dont give a damn but does anyone know a way to get back into an instagram account? I was dumb forgot my account password. I appreciate any assistance you can offer me!

@Maximilian Rudy instablaster =)

[@maximilianrudy8231]

@Maximus Deshawn Thanks for your reply. I found the site thru google and im trying it out atm. Seems to take quite some time so I will get back to you later when my account password hopefully is recovered.

[@maximilianrudy8231]

@Maximus Deshawn It worked and I finally got access to my account again. I'm so happy:D Thank you so much you saved my account :D

[@maximusdeshawn4409]

@Maximilian Rudy happy to help :)

[@hichamfarhat28]

Thank you

[@charitykisirisa4683]

useful video

[@skullet2461]

@TerraLearn Thanks for the video! Just a question, how do you calculate the hydraulic gradient (as in which values do you use) based on the flow lines that you have constructed? Could you please make a video on it? Thanks heaps! This was very helpful (made up for a 2hrs lecture!) :D

[@daneandersen8181]

Thanks! The hydraulic gradient is the difference in groundwater elevation between two points. For instance, say you were standing at a well and you measured the groundwater elevation in that well to be 100 feet above sea level (let's call that e1). Now imagine another well that is 100 feet away from you. You measure the groundwater elevation in that well to be 50 feet above sea level (e2). The hydraulic gradient would the the change in groundwater elevation (50 feet) divided by the change in distance between the two wells (100 feet). So, hydraulic gradient= e1-e2/length= 100-50/100=0.5. Make sense?

[@skullet2461]

Yes! That makes a lot of sense now that you've explained it. Thank you very much for your help!

Please speak in Hindi pls

[@daneandersen8181]

haha i dont know Hindi... sorry

[@andyparks6120]

You think your smart dont you?

[@daneandersen8181]

Reasonably smart I guess
