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 takeTypes of Strainers in Wells
Following are the types of strainers used in water wells: Cook strainer Browlie Ashford Leggett Phoenix Layne and brownlieDesign 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
Uses & Effects of Canal Irrigation
Irregular supply of water in the rivers is then regulated by construction of dams & barrages. Canal system irrigates a vast area. Even the deserts have been made productive. Cheap labour and availability of cement reduces the cost of canal construction. Huge quantities of water from Monsoon rainfall & melting of snow can be stored in reservoirs during
Factors Affecting Crop Water Requirements
A certain crop grown in a sunny and hot climate needs more water per day than the same crop grown in a cloudy and cooler climate. There are, however, apart from sunshine and temperature, other climatic factors which influence the crop water need. These factors are humidity and wind
Classification of Irrigation Schemes
Irrigation Projects include storage dams, diversion works, barrages, lift irrigation schemes and tube wells. Irrigation Projects are divided into the following three categories viz., Major, Medium and Minor Projects. The criteria of classification is as under: Projects having CCA more than 10,000 ha. are classified as Major Projects Projects having CCA more than 2000 ha.
