Float-Area Method<\/strong> <\/span><\/p>\n

Untuk mengira Discharge bagi sebuah sungai formula ini digunakan:<\/p>\n

Q=V \u00d7A<\/p>\n

Di mana
\nQ = Discharge
\nV = Velocity
\nA = Cross-Sectional Area (Luas keratan rentas sungai)<\/p>\n

Untuk menyelesaikan formula di atas, nilai bagi A dan V mestilah diperolehi terlebih dahulu.<\/p>\n

Untuk mendapatkan nilai A;<\/p>\n

A=Width \u00d7Depth ; [Lebar \u00d7 Kedalaman Sungai]<\/p>\n

Untuk mendapatkan nilai V,<\/p>\n

V=s\/t<\/p>\n

Di mana
\nV = velocity
\nS = Displacement
\nt = time<\/p>\n

Untuk mendapatkan nilai velocity dari experiment Float-Area Method, objek yang diapungkan akan dilepaskan di atas sungai banyak kali.
