RADAR LEVEL SENSOR
Advantages Disadvantages Non-contacting, and not
affected by dirty water, or aquatic wildlife
Not affected by fluctuating water temperatures
Not affected by high flow rates
Easy to calibrate Low maintenance Can withstand freezing
temperatures Long term reliability
Affected by air temperature fluctuations
May reflect off floating foam or debris
May be affected by turbulent water (A stilling well may be required)
Some delay between the time when power is first applied and the first output
Gov
ernm
ent o
f the
Pun

FLOAT TYPE SENSOR:WORKING PRINCIPLE
A float-cable-counterweight-system transfers water level changes to the float pulley on the encoder unit. The position of the pulley changes in a rotating movement and this movement is converted into an electrical signal which is transferred by the transducer cable to the data logger and then saved as a measured value .

FLOAT WITH SHAFT ENCODER WATER LEVEL RECORDER
Advantages Disadvantages Not affected by water
temperature Low effect of changing
air temperature Low maintenance Low cost Can withstand freezing
temperature
Stilling well required Cable may slip (Pulley and
counterweight type only) Easily damaged unless
enclosed May wear if water level
remains at one position for extended periods
Corrosion/Salt build up may jam the pulley
Some sensors damaged by flooding

SUBMERSIBLE PRESSURE TRANSDUCER
Advantages Disadvantages Easy to install Low power draw Not usually affected by
air temperature fluctuations
Almost no time lag No delay between the
time when power is first applied and the first output
Damaged by ice Can clog in dirty water Susceptible to malfunction if often
allowed to dry May hang up debris Adversely affected by water
temperature fluctuations Range is not adjustable Desiccant must be periodically
replaced Lightning protection
recommended Damaged if submerged too deep Easily damaged by aquatic
wildlife and floods.

NON-SUBMERSIBLE BUBBLER PRESSURE TRANSDUCER
Advantages Disadvantages Easy to install and
calibrate Electronics can be
installed away from the water
Only inexpensive bubbler tubing contacts the water
Insignificantly affected by air or water temperature fluctuations
Insignificantly affected by drying
Not easily clogged by dirty water
May hang up debris Requires one of the following:
o A large nitrogen tank which must be periodically refilled
o A power-hungry air compressor with desiccant packs which must be periodically replaced
Sensor output may lag behind a changing water level

Currently decision making is largely based on experience rather than scientific knowledge.
Decision making is based on century old rules and practices.
Now insufficient to meet the needs of efficient water management.
Quality and timely data availability is lacking for appropriates decision making.
Transparently, equity in water allocation and its distribution is lacking.
Water accounting and auditing needs to be more efficient.
DSS – Background
Gov
ernm
ent o
f the
Pun
jab
Water availability forecasts.
Assessment Punjab’s share.
Crop water requirements and placing indents.
Conveyance of water in river and irrigation network.
Water conservation at storage sites.
Assessment of hydraulic performance of irrigation canals.
Inadequate, untimely data availability for decision making.
MAJOR ISSUES
Gov
ernm
ent o
f the
Pun
jab
Efficient systems for decision making andinformation management are required.
Development of comprehensive Water ResourcesManagement Information system and DecisionSupport System would help greatly policy makersand system mangers to take informed decisionfor efficient management of irrigation water.
HOW TO MANAGE ?
Gov

A computer based set of tools.
Consists of interactive, graphical and modeling characteristics.
Addresses specific problems and assist users in study and search for a solution to problems.
Main characteristics as follows:- Helps decision makers at the upper levels.
- Flexible and responds quickly to questions
- Provides “what if” scenarios; and
- Considers the specific requirements of the decision – makers.

Development of DSS to perform:- Accurate forecast of water availability.
- Determining water share of Punjab.
- Defining the share of each main canal and preparing equitable main canals’ rotation and operation plans.
- Forecasting real time irrigation water requirements.
- Determine flow routing through rivers and link canals.
- Placing indents to Indus River System Authority (IRSA) by taking care of the following:
• Conserving water at storage sites.
• Minimum effects on power generation,
SCOPE OF WORK - DSS
