Explanation:
Detailed explanation-1: -The height of the dike should be above the highest tide and flood that occur in the site. The design flood level is based on the maximum flood water that was observed in the locality to recur within 10 to 15 years (in Chapter 2).
Detailed explanation-2: -You can remove the water with a pump, a pump diverter on your existing pump, a shop vac or pond vacuum, or even just an old fashioned suck-on-a-hose-downhill syphon. I even get a good bit of the water that I change out of my pond out with a bucket, as I dip water out regularly to water other plants.
