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 three main types of salt affected soils. The types are: 1. Saline Soil 2. Sodic Soils 3. Saline-Sodic Soil. Type # 1. Saline Soil: Soil that contains sufficient soluble salts to impair its productivity is known as saline soils, also called as Solonchak. These salts are mainly of chlorides and sulphates of sodium, calcium and [...]
