Hello, I'm Thai. I used to participate the 11th IESO Thailand camp for selecting representative of Thailand. I have one question about hydrograph.

If many weirs are built, what is changing of the normal hydrograph? (The x-axis and y-axis of the hydrograph are time in hour unit and discharge in cubicmeter per second unit respectively.) Thank you.

I have difficulty in studying paleontology for IESO ET..

Can somebody suggest good resources to study from..(preferably videos)

Just say a few lines about yourself so that people get to know each other. :)

This is my website and I have added a lot of reference materials for International Earth Science Olympiad

i got 60 in entrance test. Will I qualify??

This is an awesome website to start with Geology. Also, I like this cool page they have: Are You a Rockhound or Just a Mineral Collector?
