Stream Correction and Protection Measures

This lecture covers the concept and design of protective measures for stream correction, focusing on increasing hydraulic capacity, modifying stream characteristics, and maximizing flood protection through plot correction and section modification. It discusses the consequences of altering stream ecology, the importance of bank protection, and the use of various protective measures such as deflectors, groynes, and embankments. The lecture also delves into the design considerations for riprap, rockfill, and geotextile installations to prevent erosion and ensure stability. Practical examples and calculations for sizing protective measures are provided, emphasizing the balance between hydraulic functionality, environmental protection, and safety against floods.
