Urban Drainage Modelling for Management of Urban Surface Water

Glossary

Catchment:

The area where all the rainwater naturally drains toward the same point (outlet)

Drainage:

Surface water coming from rain either drains (percolates) into the (permeable) ground or runs off to the location in the area with the lowest point of elevation. The water which does not drain requires transporting away from the catchment premises. The task of designing sewer systems for that purpose is called drainage

Percent imperviousness:

The average percent of an area considered impervious for drainage of rain

Sewage:

Wastewater from households or industry transported in sewer pipes

Surface runoff:

The water which runs off the surface and does not drain into the ground is termed surface runoff
