This Presentation covers the topic of surface and subsurface tile drainage which is the part of canal irrigation. The content covered in this has been explained thoroughly with theory and Diagrams related to the topics and consists of various pictures to explain the content completely .Thank you.
The following file contains contents regarding Evaporation. Different methods to measure evaporations.
Primarily three methods are mentioned to measure Evaporation, that is Empirical Methods, Analytical Methods, and By using Evaporimeter or Pan.

Introduction:
Necessity of irrigation- scope of irrigation engineering- benefits and ill effects of irrigation- irrigation development in India- types of irrigation systems, Soil-water plant relationship: Classification of soil water- soil
moisture contents- depth of soil water available to plants-permanent
and ultimate wilting point
Water requirements of crops:
Depth of water applied during irrigation- Duty of water and deltaimprovement
of duty- command area and intensity of irrigation consumptive use of water and evapotranspiration- irrigation efficiencies- assessment of irrigation water
Flood has a great role in the socioeconomic status of the community living in the sourrounding of the river. How to analyze and manage the flood water is a real issue facing throughout the world specially in the developing countries. Unit Hydrograph play a vital role in predicting and analyzing the watershed water.
SWaRMA_IRBM_Module6_#4, Sediment management including landslide and river ban...ICIMOD
This presentation is the part of 12-day (28 January–8 February 2019) training workshop on “Multi-scale Integrated River Basin Management (IRBM) from the Hindu Kush Himalayan Perspective” organized by the Strengthening Water Resources Management in Afghanistan (SWaRMA) Initiative of the International Centre for Integrated Mountain Development (ICIMOD), and targeted at participants from Afghanistan.
Water is required for agriculture.
Sometimes this water requirement is fulfilled by rain, but there are some dry areas where irrigation is the only process by which water is supplied to crops.
Sprinkler Irrigation is a method of applying irrigation water which is similar to rainfall.
Water is distributed through a system of pipes usually by pumping at pressure above 2 kg/cm2.
It is then sprayed into the air and irrigated entire soil surface through spray heads so that it breaks up into small water drops which fall to the ground.
Pressurized irrigation through devices called sprinklers.

Paste Viscosity!
Attained by one of three means:
High cement content
High content of Fly Ash, Silica Fume etc
Use of Viscosity Modifying Admixture
Also low water content using HRWR
this slide about new Technics design sefl compecting concrete. it dose not required for compaction. its best to apply where compaction is not possible or critical.
