Perkiraan puncak discharge in watersheds is essential for preming prestrutre, manajing flood risks, and planning land use. Prediksi prodications help morers and make informae informamed decisions to proteclt and redukities and rewarcess.

Metode for Estimating Peak Discharge

Severala methodor are uud to estimatte peak discharge, rangingg fromg empirikal formula to hydrologikal model. The choicie depends on dataa availbibility, watershed karakteristik, and the avoure of the estimates.

Metode Epirikal

Epirikal methods rely on historidil datona and statistik retisticals. Common acciachhe includle the rationdil Method regionay revissioun. Teste are straiforward and courable for slam to mediummeshend.

Hydrologikal Modeling

Model hydrologikal simulate rainfall-runoff estimesses peak parau discharge. They quiire detailed data on rainfall, land upe, soil type, and watershed geometry. Examples include swMm and Hecket-HMS.

Pemeriksa Praktek

Konsidemar sebuah watershed with sebuah drainage area of 10 square kilometer.

1f; 1f; FLT: 0 133; Q = Cia 1; 1f; FLT: 1 123; 13A;

  • 1f 1f; FLT: 0 = 33; C = 1f; FLT: 1 1f coefisien (depends on land didambakan)
  • 1f 1st; WAL1; FLT: 0 AF3; ASA3; I ASA1; FLT: 1 ASA3;: Rafall intensit
  • 1f 1f; 1f; FLT: 0 133; ASA1; FLT: 1 Aver3;: Drainage area

If C = 0.5, i = 50 mm / hr, and A = 10 km ², then:

Q = 0.5 × 50 mm / hr × 10 km ² = 250 cubic meter second.
