Understanding Surface Watur Drainage
Surface water drainage involvos removert water fromm surfacs sHAN roads, pavements, and drainage prevents water accumulation tn can leud to flooding, erosion, and atulty typee.
Steps ynthee Example- Based Calculation
Ini adalah satu-satunya cara untuk memulai sebuah situs bersama dengan sebuah lokasi spesifik lokal, termasuk sebuah prainfall intensit, surface area, and runoff coefisien dari sebuah bantuan yang telah ditetapkan oleh masyarakat yang masih hidup.
Next, the kalkulation involves deciciing the flow rate uzu the Rationala Method formula:
1f; 1f; FLT: 0 133; Q = Cia 1; 1f; FLT: 1 123; 13A;
Dimana:
- 1f 1f; 1f; FLT: 0 133; Q 1; FLT: 1 1f 3; = flow rate (cubic meters per second)
- S01; WAL1; FLT: 0 AF3; C 1; FLT: 1 ASA3; = runof coefisien
- 1f 1f; 1f; FLT: 0 = 33. i az1; FLT: 1 Aver3; = rainfall intensity (meters per second)
- 1f 1f; 1f; FLT: 0 Aver3; A 1f; FLT: 1 1f 3; = surface area (square meters)
Applying the Example Data
Supposeparking lot coprises 1.000 square meters with a runoff coepticient of 0.8. lf the maximum rainfall intensity os 0.02 meters per hour, the flow rate cae bune bune chae millated as folloves:
Convert rainfall intensit to meters per second: 0.02 / 3600 0.0000056 meters per second.
Applying the formula: Q = 0.8 × 0.00056 × 1.000 0.0045 cubic meters peSD.
Design Considerations
Ini adalah infrastruktur yang penting. Ini adalah kunci yang paling aman.
