Spiritual gifts are not innate, natural talents, like an ear for music or the ability to draw, but rather they are empowerments that the Holy Spirit gives to a believer to minister to the body in ways that were not possible by mere natural effort apart from the Holy Spirit.
In the design of a dam, the first step is the determination of various forces which acts on the structure and study their nature. Depending upon the situation, the dam is subjected to the following forces: 1. Water pressure. 2. Earthquake forces. 3. Silt pressure. 4. Wave pressure. 5. Ice pressure. 6.
There are limits to the amount of hydroelectric energy a dam can provide. The most limiting factor is silt that builds up on the reservoirs bed. This silt is carried by the flowing river, but prevented from reaching its normal destination in a delta or river mouth by the dam.
