Choice and Selection of Irrigation Methods

The type of irrigation system selected is an important economic decision. Some types of pressurized systems have high capital and operating costs but may utilize minimal labour and conserve water. Their use tends toward high value cropping patterns. Other systems are relatively less expensive to construct and operate but have high labour requirements. Some

Types of Tube wells

In design, find its length, slot size, opening area, diameter and material requirements Corrosion resistant Strong enough to prevent collapse Prevent excessive movement of sand into well Materials used for Tube Well Construction Zinc free brass Stainless steel Low carbon steel High copper alloy

Advantages and Disadvantages of Surface Irrigation Methods

Surface irrigation is the introduction and distribution of water in a field by the gravity flow of water over the soil surface. The soil acts as the growing medium in which water is stored and the conveyance medium over which water flows as it spreads and infiltrates. Common surface irrigation systems used are rill irrigation, furrow or border irrigation. The term 'surface

Construction of Water Wells

A water well is a lot more than a drilled hole, but for many people, the above ground part of the drilling process is the only part they see. A water well is a specially engineered hole in the ground; For ground water monitoring, or for scientific research purposes, wells may be drilled in a way that allows the specialists to closely examine the rock formations and take

Types of Strainers in Wells

Following are the types of strainers used in water wells: Cook strainer Browlie Ashford Leggett Phoenix Layne and brownlie

Design Of Non Erodible Channels

The Initial dimensions of a channel are determined by uniform flow or manning formula. But final dimensions are determined on the basis of 1. Hydraulic efficiency 2. Empirical rule of the best section. 3. Practicability And Economy

Causes, Importance And Prediction of Flood

Flood is a natural even which has always been an integral part of geological history of earth. It occurs along rivers, streams and lacks. Most of the hydraulic are designed on flood record. Small hydraulic structures are based on a minimum of 25 years flood records e.g all structure constructed in the canal, soil conservation practices etc. Large irrigation projects are based on 100

Public Health Engineering

The public health engineering sector is responsible for the Collection of water, purification, transmission and distribution of water. A Public Health Engineer has to perform his job by calculating design flow, design population, design area and population density. Quality of the collected water is checked by physical and chemical tests on water and if the quantity is not

Population Forecasting Methods & Techniques

Population is one of the most important factors for design of the water systems, so it should be estimated, so as to know the increasing demand and ensure continuous supply to them. Population data is obtained by previous records and the rate of increase is found out and this used for further analysis, which may be by using the methods described below

Sectoral Consumption of Water

Domestic uses of water include the consumption of water for drinking, washing, cooking, toilets, livestock etc. the domestic average use per capita per day is 50 – 90 gallons (70 – 380 liters per capita per day).

Types of Pavements - Flexible Pavement / Rigid Pavement

Flexible pavements are those pavements which reflect the deformation of subgrade and the subsequent layers to the surface. Flexible, usually asphalt, is laid with no reinforcement or with a specialized fabric reinforcement that permits limited flow or re positioning of the roadbed under ground changes. The design of flexible pavement is based on load

Factors Affecting Selection of Water Source

The quantity of water available at the source must be sufficient to meet various demands and requirements of the design population during the entire design period. Plans should be made to bring water from other sources if the available water is insufficient. The water available at the source must not be toxic, poisonous or in anyway injurious to health. The impurities

Sources of Fresh Water in Environmentl Engg.

The quantity of water available at the source must be sufficient to meet various demands and requirements of the design population during the entire design period. Plans should be made to bring water from other sources if the available water is insufficient.

Chemical Characteristics of Water

Hardness is the property that makes water to require more soap to produce a foam or lather. Hardness of water is not harmful for human health but can be precipitated by heating so can produce damaging effects in boilers, hot pipes etc by depositing the material and reducing the water storage and carriage capacity. Absolute soft water on the other hand is not acceptable

Preliminary Treatment of Water

The first unit operation generally encountered in wastewater treatment plants is screening. A screen is a device with openings, generally of uniform size, that is used to retain solids found in the influent wastewater to the treatment pant. The principal role of screening is to remove coarse materials (pieces of wood, plastics, rags, papers, leaves, roots etc.) from the
