Methods Of Water Proofing

DATA REQUIRED FOR DESIGN OF AN IRRIGATION SYSTEM

(Since all this data will lead to the best possible system being designed attempt should be made to answer all the questions possible)

( For design of a system for lawns drawing will suffice though the knowledge of plants proposed to be planted will help)

Name

Address

Telephone

A) Map of irrigation project site.

Should include the roads channels, boundaries, water source and direction of rows

B) Crop Data

Type of crop

Net Growing area in ha

Height of growth

Row spacing

Plant/ tree spacing

Rows direction

Date of sowing/placing

Date of harvesting

Required irrigation system

C) SOIL DATA

      ·        Soil texture (medium Sand, fine sand, loamy, clay loam, clay)
·        Infiltration rate
·        Soil depth
·        Soil pH
·        Soil salinity

D) WATER SOURCE

      ·        Type of water source (well, river, channel , lake etc,)
·        Available flow rate
·        Time limitation of water supply
·        pH of water

E) PUMPING DATA

      ·        Type of energy source
      ·        Electric current supply    (voltage/phase/cycles.)
      ·        Information about pump   (pump speed and BHP)

Flow rate (m3/hr.)
Dynamic head
Efficiency
Discharge outlet dia

     ·        Information about existing well (Casing diameter , static water level and flow rate)
     ·        Information about open water source (Suction level max and min)
     ·        Difference of elevation between pump and highest point in field.

F) Irrigation operation and control

· Available working time for irrigation per day/and no f days a week.
· Desired irrigation control (Manual, automatic, and manual with provision for future automation.)

G) Climatological data

· Wind (Velocity, duration direction)
· Maximum and minimum temperatures during season.

H) Options for future development

I) Special local problems if any
