Obliczanie tej surface water drainage capacity is essential for designing effective drainage systems in urban and rural areas. An example- based approvach uses real-contribud data to determinate thee capacity needed to prevent looding and manage runoff efficiently.

Understanding Surface Water Drainage

Surface water drainage involves removing excess water frem surfaces such as roads, pavements, and.fields. Proper drainage prevents water acculation that can lead to flooding, erosion, and comperty damage.

Etapy te - Based Calculation

Te procesy zaczynają się with collecting data from a specific location, including ding rainfall intensity, surface area, and runoff coefficients. This data helps in estimating thee volume of water that needs to o be drained with a certain period.

Next, thee calculation involves determinang thee flow rate using thee Rational Method formula:

Xi1; Xi1; FLT: 0 Xi3; Xi3; Q = CIA Xi1; Xi1; FLT: 1 Xi3; Xi3;

Kiedy:

  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Q Xi1; Xi1; FLT: 1 Xi3; Xi3; = flow rate (cubic meters per second)
  • Xi1; Xi1; FLT: 0 Xi3; Xi3; C Xi1; Xi1; FLT: 1 Xi3; Xi3; = runoff coefficient
  • (zob. pkt 2.1.1.1 niniejszego załącznika)
  • BL1; BL1; FLT: 0 BL3; BL3; A BL1; BLT: 1 BL3; BL3; = powierzchnie area (square meters)

Appliing the Example Data

Poszukuj parking lot obejmuje 1.000 square meters with a runoff coefficient of 0.8. If thee maximum rainfall intensity is 0.02 meters per hour, thee flow rate can be calculated as follows:

Konwersja opadów deszczu intensity to meters per second: 0.02 / 3600

Approvying the formula: Q = 0,8 × 0,00000556 × 1,000 0,00445 cubic meters per second.
