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

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 .

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

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.

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

ernm

ent o

f the

Pun

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.

DSS – CONCEPTUAL LAYOUT

Gov

ernm

ent o

f the

Pun

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
