Objective Question
Which one of the following conditions is correct for a channel to behave in true regime?
Which one of the following conditions is correct for a channel to behave in true regime?
Silt charge is constant
A channel is said to be in true regime when it has attained a stable condition in which the channel dimensions, slope
and flow characteristics remain constant.
According to Lacey's regime theory, the silt charge and silt grade should remain constant for a channel to maintain
regime conditions.
जब कोई नहर (Channel) ऐसी स्थिर अवस्था प्राप्त कर लेती है, जिसमें उसकी चौड़ाई, गहराई, ढाल तथा प्रवाह की विशेषताएँ स्थिर रहती हैं,
तो उसे रेजीम अवस्था (Regime Condition) कहते हैं।
Lacey के Regime Theory के अनुसार, ट्रू रेजीम के लिए गाद की मात्रा (Silt Charge) तथा गाद का ग्रेड (Silt Grade) स्थिर होना चाहिए।
