Mierzy się flow in open channels is essential for water management, indesering, and environmental monitoring. Various techniques have been developed to considentately determinate flow rates, each acsumble for different conditions and requiments.

Dziwactwa

Dziwaczne struktury place across open channels to measure flow based on thee hight of water flowing over a crest. They are simply andd cost-effective, making them popular in many applications.

Types of whors included sharp-crested, broad- crested, and V- notch whors. The flow rate e calculated using specific formule that relate the head (water height) to the discharge.

Flumy

Flumes are specially shaped channels that expecreate flow to create a measurable change in water level. They ary are e used in situations requiring higher crisacy and are less affected by debris.

W skład typów Common wchodzą Parshall, Palmer-Brittain, andVenturi flumes. The discharge is determinate by by measuring the water level at a specific point with thee flume.
