Possible Functions of a Distributary Head Regulator

1. Regulation of Supply Entering the Distributary
A distributary head regulator serves the function of regulating the supply entering the distributary from the parent channel. This is important to control the flow of water and ensure a balanced distribution of water to the various branches of the distributary system. By adjusting the regulator, the flow can be controlled to meet the demands of the distributary.

2. Maintenance of Constant Water Depth
Another function of a distributary head regulator is to maintain a constant water depth in the distributary. This is crucial for efficient water distribution and irrigation purposes. By adjusting the regulator gates or valves, the water depth can be controlled and maintained at the desired level, ensuring optimal water flow and distribution.

3. Control of Silt Charge Entering the Distributary
A distributary head regulator also plays a role in controlling the amount of silt entering the distributary. Silt deposition can reduce the carrying capacity of the distributary and affect its efficiency. The regulator can be designed with features such as sedimentation basins or settling tanks to trap and remove silt before it enters the distributary, ensuring a clean and silt-free flow of water.

4. Safe Passage of Fish
Ensuring the safe passage of fish into the distributary is another important function of a head regulator. By incorporating fish ladders or fish pass structures, the regulator allows fish to migrate upstream or downstream without hindrance. This is particularly important for maintaining the ecological balance of the water system and preserving aquatic biodiversity.

Correct Statements
Based on the given options, the correct statements are:

- Statement 1: To regulate the supply entering the distributary from the parent channel.
- Statement 3: To control the silt charge entering into the distributary.

Therefore, the correct answer is option 'B' - 1 and 3 only.
