Would placing sand along the sides along the coasts of the river and increase the height of the coast, so that if any flood occur , it would be harder to overflow?

You could do that and also create another bank about 25 ft or so back from that one and have any overflow hit that bank and flow back into the river. A secondary defense.

I personally don't think these defences, like building dykes are safe. Better leave smaller islands for nature and animals. People should settle in safe parts of the world and keep a check on their population. Global warming is a truth and soon many small island countries shall disappear. City of venice is already drowning. Sweden and Norwary have built dykes and pushing the sea back. But when some nature force strikes, there is a huge loss of men and property. Govt should encourage ppl to vacate such islands sooner and help them settle some where safter, before somthing unpredictable strikes.

the defences fail due to the erosion / failure of their toes, so stabilize the base by means to preventing the water to leech out the soil.
a bulky and porous wall that does not fully resisit the water (does not creat a splash) lives longer than a rigid wall

pretty much, just depends on the placement. Also you need alot more than just a row because the preasure of the water is very high.
