Open water channel control for bypassing river chokes

Rivers are a primary source for irrigation and domestic water. However, naturally occurring narrow sections in rivers can restrict flow and cause water shortages. Irrigation channels play a crucial role in transporting water to agricultural fields and secondary channels. In this paper, we propose a control strategy for irrigation channels that allows large water volumes to bypass river bottlenecks without disrupting normal channel operations. The strategy involves a bumpless transfer between a standard distant downstream control configuration and a hybrid configuration combining upstream and downstream control. When the bypass is no longer needed, the system can be seamlessly returned to the standard configuration. We compare our proposed approach with the standard configuration by simulating a 7-pool system. The results demonstrate a significant reduction in water level deviations during bypass operations.
