Coriolis effect on a river flowing north-east?

Click For Summary

Homework Help Overview

The discussion revolves around the Coriolis effect as it applies to a river flowing at a specific angle and speed at a given latitude. The original poster is trying to determine the depth difference on either side of the river due to this effect.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster has attempted to start the problem by drawing a diagram but expresses confusion regarding the variables involved, particularly the angular velocity and the velocity vector of the river.

Discussion Status

Participants are engaging in clarifying the definitions of the variables involved, such as angular velocity and the velocity of the river in vector form. There is an ongoing exploration of the necessary components to apply the Coriolis effect correctly.

Contextual Notes

The original poster indicates a lack of clarity on specific terms and variables, which may impact their ability to progress with the problem. The discussion is focused on understanding these foundational elements before moving forward.

Homework Statement


Consider a river of width 1000 m flowing 30 degrees east of north with a speed of 10m/s at latitude 50 degrees north. The river bottom is flat. On which side of the river is the water deeper and by how much?

Homework Equations


the only correction i need to use is -2m(omega cross v). I can't figure out what omega is.. then after that I don't know what to do. Any help?

The Attempt at a Solution


I've started it and drawn a diagram, but after that I'm lost.. any help would be great! thank you!

ω is the angular velocity of the Earth …

it goes through the Earth's axis :wink:​
 
Sorry! I meant I don't know what v is, is it the velocity of the river in vector form?

yes of course
 
thanks :)
