Design of Chute Spillway
In the previous lecture, chute spillway and its components of chute spillway are discussed. In this lecture, design of SAF stilling basin and structural design of chute spillway is discussed.…
Design Requirements of Gully Control Structures
A structure installed across an active gully to stabilize the gully through control of erosion of gully bottom and banks is called gully control structure. Design Requirements of Gully Control…
Grassed Waterways
Grassed waterways are natural or man made constructed channels established for the transport of concentrated flow at safe velocities from the catchment using adequate erosion resistant vegetation which cover the…
What Is Terrace Farming?

What are contour ditches?
Contour ditches are horizontal ditches dug on the slope of a hill to catch the rainwater running down the hill. Because the ditch is on the contour of the hill…
Trenching
Trenching is one of the major engineering measures for erosion control in non-arable lands and is mainly aimed to slope stabilization and drainage line treatment. The area with steep slope…
Vegetative Barriers for Erosion Control
The use of stiff-stemmed vegetation as barrier strips in cropland areas vulnerable to erosion is a new conservation practice that can augment more conventional measures designed to reduce soil losses.…
Controlling Erosion of Soil by Water: 9 Biological Methods
Biological Method # 1. Contouring: The term contouring, also referred to as contour farming, applies to the tillage practices or applying all treatments on the contour in agriculture pasture or…
Conjunctive use of surface and groundwater
SURFACE WATER OR GROUNDWATER? Disadvantages of surface water development compared to groundwater In most climates of the world, precipitation, either rain or snow, and consequently peak runoff corresponding to a…
Runoff, erosion and sedimentation: prediction and measurement
RUNOFF Runoff forms There are two situations when runoff will occur. If the intensity of rainfall exceeds the infiltration rate at the ground surface, ponding will lead to surface flow.…
