Delineation of Groundwater Potential Zones Using GIS/Remote sensing Techniques and AHP
Delineating the potential groundwater zones using Remote Sensing (RS) and Geographic Information Systems (GIS) is a viable apparatus. In recent years, broad utilization of satellite information along with conventional maps and amended ground truth information, has made it simpler to set up the standard data for groundwater potential zones. Remote sensing not only provides a wide-range scale of the space-time distribution of observations but also saves time and money. (Kumar et al. 2014). In addition, it's widely used to characterize the earth's surface (such as lineaments, drainage patterns and lithology) yet on examine the groundwater recharge zones.

How to calculate NDVI using Erdas Imagen
Просмотров 1,2 тыс.5 лет назад
Normalized Difference Vegetation Index (NDVI) quantifies vegetation by measuring the difference between near-infrared (which vegetation strongly reflects) and red light (which vegetation absorbs).

Tutorial on Regional Groundwater Modeling Using MODFLOW with ModelMuse GUI
Просмотров 10 тыс.6 лет назад
This tutorial shows procedures on how to build, run and import/export results of a MODFLOW model. The input files and details on example problem can be found at blog link :agualabs.edublogs.org/
Thankyou Dear
What a nice presentation, please Dr. Kider, launch sessions on real data set as much as possible.
Wonderful video and informative keep it up
Very excellent video. Learn a lot from it. Is it possible to have both production wells and observation wells in the same model? what would be the package to use if using MODFLOW-NWT?
bravo bro
Thanks for exemple, Kedir.
Interesting part shukren
Thank you so much for this amazing tutorial. I am not able to change my aquifer from confined to convertible. Kindly help me.
Excellent work done. Thanks for a great explanation of the data and problem
Thank you so much for this amazing tutorial. I'm trying to do a model for a state in India. I just wanted to know that how did you find out the Conductance per unit length or area as 0.001
calculate ndvi of previously stacked sentinel 2 image?
Good one bro
how are you doing dear, the tutorials which you were releasing are very interestive , but also require the tutorial for how to prepare hydrogeological map. plse support me , now l am working my pg in hydrogeology stream.
Thank you Mr. K.M Bushira for such a wonderful explanation. I'm Sierra Leonean and trying to do a model for a local state. I've imported the model and try to generate a grid,but,the software is telling me "Grid generation canceled because only one column boundary would have been created. I've tried so many other ways to do it,but to no avail. Would be so happy if anyone would help
How to add variable thickness of the layers in the model?
Please refer another video of mine with a title inserting DEM..............
The explanation is very clear. Thank you for this video
Dear Sir, I have question about runoff calculation from CNgids. I used hec-geohms to create CNgrid, I want to find runoff from SCS equation. I have the interpolated rainfall map and maximum retention(S) found from CNgrids and i used raster calculater to find runoff, however every time the result of the created raster is zero. how you advice me to solve this issue. Thanks in advance for your respond
interesting and informative too...👍👍👍👍
Greatly explained
nice one
Dear kedir, your videos are very interesting and helpful specially for water related research, and I seen your tutorial on ground water potential zone mapping, image classification on ERDA ... I need the AHP analysis excel package to determine weight of each parameters used, please forward with this email. thank you for your support. kassiea2014@gmail.com
Interesting
Dear Dr. Kedir, Nice to meet you. And thanks a lot for sharing your experience about GWM for free on public media, youtube. Stay Safe
Hello sir, Please kindly send me a copy of the AHP excel sheet used in groundwater potential zone 🙏. Your videos are really helpful. Thanks so much ololade.olaleye@gmail.com Thanks
Sir, how can I save an image after unsupervised classification is done, I want to save the classified image for the purpose of publishing an article I am very new to ERDAS. Please help me, sir, Thank You
Sir i have watched your, AHP approach for UGpz. Can please send me...your AHP calculator Excel, i hve send you messages also in your website. it will be very helpful to me please sir i need it so much.
Raw at, I will send you as soon as I can
@@kedirbushira_GW i have got your mail sir, thank you so much for helping me.🙏🙏
Hello neeraj please i came here for the same purpose after watching the GWPZ by keedir. Please kindly share the excel sheet with me please 🙏. ololade.olaleye@gmail.com
the imported file is not shown up. it has shown up only in the 3D sections. what is wrong in this case?
Follow the procedure.you have to interpolate it to be displayed in the cross section view.
Thanks, Dear Dr Kedir
Dear Kedir, Thank you very much, it is very helpful. Is that possible to estimate groundwater recharge using modflow model? also please upload calibration and validation tutorial.
Hi. thankyou for sharing such useful information. Please, can you tell me at what point I am doing wrong as my runoff raster is 2 columns and one row? I have done everything as you said, again and again, but the result is the same. Looking forward to seeing you soon. Thanking you in anticipation.
I had subscribed sir...plzz put a video for groundwater recharge using rainfall data
Thank you for ur reply!!!!.....then what are the data used for find initial head ,hydraulic conductivity and boundary condition...can you put a video for this..plzzz
Could you please go to the blog (agualabs.edublogs.org) for more. Subscribe the channels for future related videos.
Is water level data needed for groundwater flow modelling??? It used for what purpose???can u plzzzz say that
The observed (measured) groundwater level data would be used for calibration purpose.Hope this will help.
How to use rainfall data in modelmuse
In MODFLOW, what is important the Recharge derived from ppt when you delt with subsurface flows. You can use infiltration derived from ppt in UZF package or recharge rate from the surface water balance.
i am lucky learning by you
what does bottom elevation -15, -30, -45 mean. what is the datum reference if bottom elevation is -45?
hi I encounter problem in model packages and programs when I choose some packages and the model send me error bug do you know where this problem may come from and how it can be fixed?
Hi Seyed, which GUI are you using.ModelMuse? Could you please use ModelMuse 3.9 or more. I havent ever had failure in modeflow package selection. If you failed to correct it, send me you model as zip file, i can check. it.
thanks
