One of the most important uses for geotextiles is as a filter in drainage and erosion control applications. Drainage examples include trench and French drains, interceptor drains, blanket drains, pavement edge drains, and structural drains, to name just a few.

Seismic retrofitting is the modification of existing structures to make them more resistant to seismic activity, ground motion, or soil failure due to earthquakes. With better understanding of seismic demand on structures.

The concrete whose density is lower than normal concrete (2200 kg/m3 or 140 lb/ft3 ) is known as lightweight concrete. It includes an expanding agent in it to increases the volume of the mixture while giving additional qualities. It is lighter than conventional concrete (Dry Density 300 kg/m3 up to 1840 kg/m3). In place density of 90 to 115 lb/ft3 compared to the

Many precipitation stations have short breaks in their records because of absence of the observers or instrumental failure. It is must to estimate this missing record. The following method is adjusted for estimating this missing rainfall data.
