Coastal City Scenario on Sea Level Rise

In the event of a meter rise in Sea Level which has actually accumulated over the last 25 years, there will be a need to build breakwaters and install pumping stations to operate 24/7/365 to prevent flooding in the downtown areas which have elevations of zero MASL ( Meters Above Sea Level ) up to 1 MASL. These pumping stations will need a total of 272.5 MW of constant power for every Meter. These figures are assumptions based on a land area of 10,000 hectares or a total of 100 Million Square Meters.

GLOBAL WARMING SIGNS

When I came back here in Davao City 24 years ago after 18 years of living in Metro Manila : The air was very fresh,  cruising along Diversion Road was like going to Baguio. When it is LOW TIDE, nothing can be seen in the drainage system. When it is HIGH TIDE,  around 5 to 6 inches of sea water is visible. There is no flooding at all during heavy rains. Starting 2008, when signs of degradation were spreading the flooding started : During LOW TIDE, the drainage is already with 12 inches water. When HIGH TIDE COMES,  The sea water is at street level or 4 inches below street level When the rains come during LOW TIDE,  the newly improved drainage system works fine, and in extended duration, the floodwaters recede faster. Disaster strikes when rains strike during HIGH TIDE, as the drainage system have no use at all. I guess this is true in all coastal cities around the world.

THE TIME HAS COME

The time has come to join my two blogs : www.sanjosepower.blogspot.com  and  www.sanjosemessages.blogspot.com. The issues of environmental and faith has just intersected with Hurricane Harvey and Irma, prompting US President Donald Trump to call for prayers. MAN has to balance development with Environmental Preservation.
