It will be very useful to study about the planning of a irrigation projects/reservoir

2. Irrigation Project:
Agricultural establishments capable of
applying controlled amounts of water to land to
produce crops are called irrigation project.
It mainly consists of engineering structures
which collect, convey, delivery of water to areas
on which crops are grown.
Ex:

3. Essential conditions for success of
irrigation project:
 Suitability of land for agriculture
 Favourable climatic conditions for proper
growth and yield of crop
 Adequate and economic supply of suitable
quality of water
 Good site conditions for hydraulic structures
for operations

4. Types of irrigation projects:
Based on purpose served
 Single purpose irrigation project
 Multipurpose irrigation project
Based on culturable command area
 Major irrigation projects
 Medium irrigation projects
 Minor irrigation projects
Based on flow of water
 Gravity irrigation projects
 Lift irrigation projects

5. Based on culturable command area
• Major irrigation projects: projects which have a
culturable command area (CCA) of more than
10,000 ha .
• Medium irrigation projects: projects which have
CCA of 2000ha to 10,000 ha.
• Minor irrigation projects: projects with CCA less
than or equal to 2,000 ha. utilizes both ground
water and local surface water resources.

6. Based on flow of water:
• Gravity irrigation projects: where the irrigation
water is conveyed by gravity for growing to the
irrigated land.
• Lift irrigation project: The water is lifted up by
pumps or by other mechanical devices for lifting
water and conveyed to the agricultural land
through channels flowing under gravity.

7. Irrigation project:
A irrigation project mainly includes
the following works:
• Storage and diversion works
• Conveyance and distribution channels
• Conveyance, control, and other hydraulic
structures
• Farm distribution
• Drainage works

8. Stages in irrigation project:
Every irrigation project undergo following
stages:
A. Development of an Irrigation Project
B. Feasibility of an Irrigation Project
C. Planning of an Irrigation Project

9. Development of an irrigation
project:
• A small irrigation project can be developed in a
relatively short time.
• a large irrigation project is more complicated and
time-consuming.
The principal stages of a large irrigation
project are:
 Promotional stage
 Planning stage
 Construction stage
 Settlement stage

10. Feasibility of an irrigation
project:
The feasibility of an irrigation project is decided
on the basis of preliminary estimates of:
• Area of land suitable for irrigation,
• Water requirements,
• Available water supplies,
• Productivity of irrigated land, and
• Required engineering works.
An irrigation project is considered feasible
if the total estimated benefits of the project exceed its
total estimated cost. Adequate planning of all aspects is
always essential for a feasible irrigation project.

11. Process of planning of irrigation
project:
• They are two stages in planning of an
irrigation project as follows
• Preliminary planning
• Detailed planning

12. Factors considering for the
planning:
• Type of project and general plan of irrigation
works,
• Location, extent and type of irrigable lands,
• Irrigation requirements for profitable crop
production,
• Available water supplies for the project,
• Irrigable areas which can be economically
supplied with water,
• Types and locations of necessary engineering
works,
• Needs for immediate and future drainage,

13. • Feasibility of hydroelectric power development,
• Cost of storage, irrigation, power, and drainage
features,
• Evaluation of probable power, income, and
indirect benefits,
• Method of financing the project construction,
• Desirable type of construction and development,
• Probable annual cost of water to the farmers,
• Cost of land preparations and farm distribution
systems,
• Feasible crops, costs of crop production, and
probable crop returns.
Factors considering for the
planning contd.

14. Preliminary planning:
• Collecting and analysing all available data for
the current study
• Doing field surveys, and determining the
feasibility of the project
• Suitability of land for cultivation can be
examined in the project surroundings
• Soil conditions can be determined from surface
& subsurface explorations for construction of
hydraulic structures

15. Detailed planning:
• Physical data needed for detailed planning
are collected by topographic and location
surveys, land and soil investigations and
geological explorations.
• Detailed plans & designs of engineering
works can be determined
• Location of hydraulic structures
• Location of hydro electric power plants etc..
