I assume for the San Francisco Bay, if sea levels rose enough to be a serious problem, they could just build some kind of dam or something across the Golden Gate. Is that correct?
- Karellen 13y agoWhere would the water from all the rivers that empty into the bay go?
- pstrateman 13y agoThe worlds only 1m high hydroelectric dam.
- mikeash 13y agoAlas, since you want to keep the water level lower inside, that means you'd have to pump the incoming flow up to get it into the ocean. Rather than generating electricity, it would consume vast quantities of it.
- pstrateman 13y agoThe tide moves 6ft+ from high to low. As long as the flow rate is less than 3ft/day then you can just wait for low tide.
- cpolis 13y agoI'm not sure if this is feasible and certainly it would be more of a process than 'building some kind of dam'. A few reasons: - The bridge spans 2700m and the channel is 350+ feet deep in some spots. For scale, the Three Gorges Dam is 2300m long - Sea levels will rise so incrementally that a massive public works project might seem unnecessary or hard to get support for - Shipping traffic needs to be able to pass through to get to the port of Oakland, Richmond, Stockton, etc...
- dsl 13y agoThis map is simply based on sea level and totally ignores sea force. If the sea were 10' higher, it would probably erode most of San Francisco within 50 years.
