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. [...]
In this article we will discuss about:- 1. Introduction to Water Erosion Risk 2. Assessment of Water Erosion Risk 3. Factors 4. Methods. Introduction to Water Erosion Risk: The assessment of relative risk of erosion to bare soil involves consideration of slope class erodibility. Previous vegetative covers are not taken into consideration for water erosion risk analysis. Also, it is [...]
