Someone plz answer

2. What are three things a hydraulic engineer would have to consider to build a canal?

1. The hydrological regime of the area.

2. The subsoil and its mechanics alongside the region of the intended canal.

3. The  Environmental Impact Assessment

Explanation:

1. The hydrological regime of the area.

Rains, rivers, floods, draughts must be considered. Volume, period, seasons and their effects.

2. The subsoil and its mechanics alongside the region of the intended canal.

Stability studies must be developed from the subsoil and soil strata and composition.

3. The  Environmental Impact

A hydraulic engineer must assess the environment impact of a work like that so that the river might not be drained too much and many of their species die.
