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. [...]
Kinnel (2004) described the transportation of soil particles under raindrop erosion in following four processes: 1. Raindrop Detachment with Transport by Raindrop Splash (RD-ST) Raindrop Detachment with Transport by Raindrop Induced Flow Transport (RD-RIFT) 3. Raindrop Detachment with Transport by Flow (RD-FT) 4. Flow Detachment with Transport by Raindrop (FD-FT). These processes are described as under: 1. Raindrop Detachment with [...]
