The methods available for gully control are – (1) Diversion of runoff, (2) Vegetative methods, (3) Construction of temporary structures, and (4) Construction of permanent structures. (1) Diversion of Runoff: Diversion of runoff is achieved by constructing diversion drains. The diversion drain is a shallow channel put across the slope above the gully. The design principles of diversion drains are [...]
The following article will guide you about how to design gully control structures. Design of Gully Control Structures: There are three steps followed in the design of gully control structures. These are: (1) Hydrologic design, (2) Hydraulic design, and (3) Structural design. (1) Hydrologic Design: The hydrologic design consists in estimating the runoff which the structure is expected to handle. [...]
The following points highlight the four main types of permanent structures for gully control. The types are: 1. Spillway 2. Rubble Masonry Dam 3. Concrete Dam 4. Gabion Structure. The gully control structures are laid in the gully section, throughout the length, according to the profile of gully bed. Amongst different types of spillways, the chute spillways are located at [...]
