Correct Answer

Options:

1. Three
2. Four
3. Five
4. Six

Correct Answer

Options:

1. Different channel patterns are not related to energy conditions and local constraints.
2. Straight channel patterns are common in natural systems.
3. Meandering channel patterns are rarely found in alluvial rivers.
4. Channel sinuosity is defined as the ratio of valley length to channel length.

Correct Answer

Options:

1. Pools and riffles at crossovers.
2. It may be possible in natural systems up to stretches of 100 meters or so.
3. Water adopts a sinuous path.
4. Defined as straight when sinuosity index is between 1.05 and 1.5.

Correct Answer

Options:

1. The ratio of valley length to channel length.
2. The ratio of channel length to valley length.
3. The ratio of channel width to channel depth.
4. The ratio of channel depth to valley length.

Correct Answer

Options:

1. Defined as straight when sinuosity index is less than 1.05.
2. A stream channel having sinuosity index more than 1.5.
3. It is characterized by pools at the bends and riffles at the crossovers.
4. A channel pattern that is rarely found in alluvial rivers.

Correct Answer

Options:
