River Information

[Rory SnowParticipant]

Is there any available information about the river that passes through the village? I’m researching a possible hydroelectric energy solution for my team. I’ve also been trying to research the state of hydroelectric power in Cambodia as a whole and I was wondering if the EWB team might have some insights on that topic.

Hi Rory,

We’ve yet to confirm this with our EWB staff in Cambodia, but according to this resource (see Map 7) listed in the recommended readings of Design Area 2 – Water Supply, it appears that the Prek Chhlong River flows through the Kaev Seima district, where Pu Ngaol village belongs to.

I did a quick Google search and found this hydropower country profile and hydropower plan, which are excellent starting points in understanding the current hydropower trends in Cambodia.

I hope this helps.

Regards,
Jean

I am doing Energy, specifically challenge 4.1 this year. Have there been any updates on this information?

Hi Lachlan,

More information on the river? Yes, please check out water supply section of the discussion forum and there are some river topography related questions as well as water sources. Hope that helps.

Cheers,
Sai

Looking at some other threads I would assume a pico-hydro system is not ideal as the head would not be very high as beyond Kratie it is only around 0.03m/km.

Hi Lachlan,

It seems like you’ve already done some calculations and estimates. While we cannot definitively agree or disagree with your assessment, I recommend that you document the data and assumptions you used. You can revisit this in the future or work with your team as a design alternative.

I simply used data from this thread. This would suggest hydropower is not feasible. However, an article linked in a different thread suggests otherwise.

As a side note, posts which feature many links seem to fail to post, which forces me to retype the response.

Edit: the number seems to be anything over 1.

Hi Lachlan,

It’s great that you’ve looked into that article! It seems like the main issue there is the sustainability of installing small-scale hydropower dams in rural areas like the Pu Ngaol village.

Hi, I discovered this source, https://sites.google.com/sheffield.ac.uk/gec24/projects/water
that states that the river that flows trough Pu Ngaol is the Ou Te, not the Prek Chhlong. Can someone please confirm if this is factual or not?
Cheers

Hi Taine,

Thanks for sharing that resource. We couldn’t confirm if Prek Chhlong river doesn’t flow through Pu Ngaol village at all. These references suggests that they seem to be two different bodies of water: Prek Chhlong (river) while Ou Te (stream)

> Technical Report on Mondulkiri Provincial Spatial Plan (2020 – 2040) – see page 28
> Cambodia: Greater Mekong Subregion Biodiversity Conservation Corridors Project – see page 16-17

What we’re sure of is that the villagers access the Ou Te for their everyday needs.

Regards,
Jean
