The objectives of seasoning of timber are as follows :-
– Improve strength, hardness and stiffness of timber.
– Make it suitable for receiving various treatments like paints, preservatives, varnishes, etc.
– Allows the wood to burn quickly if it is used as fuel.
– Reduce the tendency of timber to crack, wrap, shrink and bend.

If a building foundation sits on soft or filled-in soil, the whole building may fail in an earthquake regardless of the advanced engineering techniques employed. Assuming, however that the soil beneath a structure is firm and solid, engineers can greatly improve how the building foundation system will respond to seismic waves.

Another solution refers to base isolation which involves floating a building above its foundation on a system of bearings, springs or padded cylinders.

The curve number method is an adaptable and widely used for runoff estimation. This method is important properties of the watershed, specifically soil permeability, land use and antecedent soil water conditions which take into consideration. Thus, straightforward methods of calculating runoff can tell you the amount of water that storms bring to the earth. For a given surface area such as a roof or yard, multiply the area by the inches of rainfall and divide by 231 to obtain the runoff in gallons.
