The drain system is simple in form: It's made up of trenches filled with gravel or rock that contain a perforated pipe that reroutes water away from problem areas. "The drain operates by allowing ...
The site design and site planning process begins with the initial problem to be solved. This is started by a client contracting a planner to work with a particular site. Analysis phase: The next step involves programming the site as well as site and user analysis , which is focused on in-depth below.

A high proportion of damp problems in buildings are caused by ambient climate dependent factors of condensation and rain penetration. [1] Capillary penetration of fluid from the ground up through concrete or masonry is known as "rising damp" and is governed by the shape and porosity of the construction materials through which this evaporation ...
Although figs are not bothered by any serious pests, occasional problems can occur. Root knot nematodes live in the soil and feed on fig roots. This feeding can stunt plant growth and reduce fruit ...
the design drain spacing (L) can be found from the equation in dependence of the drain depth (Dd) and drain radius (r). Drainage criteria One would not want the water table to be too shallow to avoid crop yield depression nor too deep to avoid drought conditions. This is a subject of drainage research.
Unlike a full-depth porous asphalt pavement, OGFCs do not drain water to the base of a pavement. Instead, they allow water to infiltrate the top 3/4 to 1.5 inch of the pavement and then drain out to the side of the roadway. This can improve the friction characteristics of the road and reduce road spray. [27]
