The ideal situation for a French drain has a natural slope, which aids with water flow, Caballero says. ... Specifically, yard trench drains cost about $30 to $90 per linear foot, per Angi.
A French drain[1] (also known by other names including trench drain, blind drain, [1] rubble drain, [1] and rock drain[1]) is a trench filled with gravel or rock, or both, with or without a perforated pipe that redirects surface water and groundwater away from an area. The perforated pipe is called a weeping tile (also called a drain tile or ...
The equation for head loss in pipes, also referred to as slope, S, expressed in "feet per foot of length" vs. in 'psi per foot of length' as described above, with the inside pipe diameter, d, being entered in feet vs. inches, and the flow rate, Q, being entered in cubic feet per second, cfs, vs. gallons per minute, gpm, appears very similar.
Drainage gradient (DG) is a term in road design, defined as the combined slope due to road surface cross slope (CS) and longitudinal slope (hilliness). Although the term may not be used, the concept is also used in roof design and landscape architecture. If the drainage gradient is too low, rain and melt water drainage will be insufficient.

Roof pitch. Roof pitch is the steepness of a roof expressed as a ratio of inch (es) rise per horizontal foot (or their metric equivalent), or as the angle in degrees its surface deviates from the horizontal. A flat roof has a pitch of zero in either instance; all other roofs are pitched. A roof that rises 3 inches per foot, for example, would ...
A drainage equation is an equation describing the relation between depth and spacing of parallel subsurface drains, depth of the watertable, depth and hydraulic conductivity of the soils. It is used in drainage design. Parameters in Hooghoudt's drainage equation. A well known steady-state drainage equation is the Hooghoudt drain spacing equation.
The bioswale channel is grass-lined and nearly linear in form. Downslope gradient is approximately 4% and cross-slope gradient is approximately 6%. [16] A relatively recent project established was the "Street Edge Alternatives" (SEA) project in Seattle, Washington, completed in 2001. Rather than using traditional piping, SEA's goal was to ...
