In general, depth of soil varies from place to place to great extent. But the top 30 cm soil depth is very useful for both human being and wild life. This layer is continuously exposed to the action of atmospheric…
It broadly classified in to two: A. Geologic erosion: B. Accelerated Erosion: 1. Wind Erosion 2. Water Erosion. Raindrop/ splash erosion. Sheet erosion. Rill erosion. Gully erosion. Stream erosion. C. Other types of Soil erosion: Glacial erosion Snow erosion Organic…
Factors Affecting Soil Erosion Factors such as rainfall, runoff, wind soil, slope, plant cover and presence or absence of conservation measures are responsible for soil erosion. But mainly three following factors affect the erosion. 1. Energy: It include The potential…
It is the technique in which deterioration of soil and it looses is reserve by using it within its capabilities and applying conservation technique for production as well as improvement of soil. Soil and Water Conservation Measures Agronomical Measure (…
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, there by reducing sheet and rill erosion and prevents…
Contour Bunding Counter Bunding are carried out in many parts in India- notably in Maharashtra, Gujarat, Tamilnadu, Karnataka and Andhra Pradesh. Contour Bunding: It consists of building earthen embankments across the slope of the land, following the contour as closely…
Basically four principles involved in pumping water: Atmospheric pressure. Positive displacement Centrifugal force Movements of columns of water caused by the difference in specific gravity. Pump Characteristic: Terminology: Capacity: It is volume of water pumped per unite time. It is…
A. Centrifugal Pumps Definition: It may be defined as one in which an impeller rotating inside a close fitting case draws in the liquid at center and by virtue of centrifugal force throws out the liquid through an opening at…
Soil, vegetation and water are most important vital natural resources for the existence of the man and his animals. These three interdependent resources can bee managed collectively, conveniently, simultaneously and efficiently on watershed basis (unit of management.) Watershed: Definition: “Watershed…
A. A large numbers of terms are very frequently and loosely used to classify watershed in different sizes [based on size] a. Micro watershedsb. small watershedsc. Large watersheds, etc Small watersheds: “Small watersheds are those where the overland flow is the…
