Procedure for using the Rational Method The rational formula estimates the peak rate of runoff at a specific location in a watershed as a function of the drainage area, runoff coefficient, and mean rainfall intensity for duration equal to the time of concentration. The rational formula is: Where: Q = maximum rate of runoff (cfs […]

Contour Bunding Bunding or construction of small embankment is carried out to reduce the length of slope, to reduce the velocity of runoff water and to hold the water in the catchment for a longer period. Thus more water infiltrates into the ground and less run-off and soil erosion take place. Different types of bunds […]

Terracing: “A terrace is an embankment or ridge of earth constructed across a slope to control runoff and minimize soil erosion”. A terrace reduces the length of the hill side slope, thereby reducing sheet and rill erosion and prevents formation of gullies. Types of Terraces: There are two measure types of terrace. Bench Terrace: which […]

1. Remote Sensing: We perceive the surrounding world through our five senses. Some senses (touch and taste) require contact of our sensing organs with the objects. However, we acquire much information about our surrounding through the senses of sight and hearing which do not require close contact between the sensing organs and the external objects. […]

What points you will consider while selecting a site for the construction of a farm pond?

What points you will consider while selecting a site for the construction of a farm pond?

by
Factors to be considered in site selection: 1. Ecological factors 2. Biological and operational factors 3. Economic and social factors In order to select a suitable site for aquaculture, the following factors have to be considered on the site (Pillay, 1977). 1. Ecological factors a. Water supply b. Water quality c. Climate d. Hydrological characteristics […]
