Design Guidelines for LID Systems

Effective LID decly involves desserala steps:

  • Konduct a site analysis to identify runoff sources and flow pats.
  • Setel Kotable LID berlatih di taman yang sangat bagus, dan juga di atap-atap yang penuh dengan rasa rakus.
  • Ensure proptur sizing based on rainfall data and runoff kalkulations.
  • Design for maintenance and accessibility.

Kalkulations for LID System Sizing

Kalkulations are vital to determinasi the capacity of LID components. The followings is a simple fied acciachh for sizing a rain garden:

First, estimate the runoff volume (V) usingg the formula:

1f 1f; FLT: 0 133; V = C × P × A JUGA; FLT: 1 123; 123; M2;

Dimana:

  • S01; FLT: 0 = 33; C = 1f; FLT: 1 13.1f = runof coefisien (depends on surface type)
  • 1f 1f; 1f; FLT: 0 = 33. P = 111; FLT: 1 Aver3; = rainfall depth (is inches or mm)
  • 1f 1f; 1f; FLT: 0 133; ASA3; A 11; FLT: 1 123; ASA3; = drainage area (is square feet or meters)

Next, convert the volume to a deptr for the raidin garden based oit surface area, ensuring it can handle the kalkulated runoff volume.
