CHALLENGES -WATER
RESOURCES• Too many institutions managing water
• Low water productivity
• Short and narrowly focused private sector engagement
• Imperfect marketing
• No firm financing plans
• Water ownership issues
• No regulator for water use
• Lack of Coordination
• Deterioration water quality
• Uncertainty in Water Availability (Spatial/ temporal)
• Sea water Intrusion in Coastal areas
• Loss of Biodiversity/wetlands
• Over depletion of GW-Increased cost of pumping
• Increased Health Risks
• Hazards of water logging and salinity

Waste water-Neglected Resource
More than 80 percent of wastewater flows back into the environment without treatment
Almost 2 billion people use contaminated water
Contaminated water is causing more than 0.5 M deaths per year
Over 80% of all waste water is not used again
663 million people still lack improved drinking watersources
Twenty million hectares in 50 countries are irrigated with raw or partially treated wastewater
By 2050, 70% of the world’s population will live in cities, compared to 50% now-more waste water

• Clogging and blockage
• Hindrance in flow
• Sedimentation
• Retention time for waste water/Deep percolation
• Degradation of lands
• Deterioration of GW quality
• Increased O&M Cost
• Bad smell and environmental degradation
• Overtopping during rainy season and breaches

Abnormal lowering of water table in sweet GW areas.
Deterioration of groundwater quality
Saline groundwater intrusion in the fresh areas
Increasing cost of groundwater pumping with declinein water table.
Concerns regarding sustainability of agriculture due tosoil salinization.
Consumption of upper freshwater layer is causinggradual deterioration of GW quality
Balance of SW supplies, recharge, and GW pumping isin danger zone

3-HYDRO-INFORMATICS
The concept of “hydro-informatics” was pioneered by MichaelB. Abbott in 1989, as the application ofadvanced computation and communicationtechnologies to problems of the aquaticenvironment.
Hydro-informatics integrates knowledge fromsocial and technical domains to helpunderstand how technical interventions havesocial consequences and how these in turngenerate new technical developments.

Hydro-informatics ???
Hydro-informatics is a branch of informatics whichconcentrates on the application of information andcommunications technologies (ICTs) in addressing theincreasingly serious problems of the equitable andefficient use of water for many different purposes.Growing out of the earlier discipline of computationalhydraulics, the numerical simulation of water flowsand related processes remains a mainstay ofhydroinformatics, which encourages a focus not onlyon the technology but on its application in a socialcontext., in the so-called artificialintelligence community, such as artificial neuralnetworks or recently support vectormachines and genetic programming etc

BACKGROUND
Rehabilitation and modernization of barrages with the financial assistance of World Bank, JICA and (ADB).
Rehabilitation of Taunsa Barrage and Jinnah Barrages and Construction of New Khanki Barrage stands completed.
The rehabilitated barrages are being provided with the latest Supervisory Control and Data Acquisition (SCADA) System.
SCADA caters for automated regulation of barrage gates, discharge monitoring, automated data collection and transmission, central instrumental observation system for piezometers to measure sub-surface flows and CCTV based surveillance system, which are all software based.
SCADA system is located in the control center and is operated in the scanning mode, communicating between the CONTROL CENTER and the REMOTE STATION(S).

Functions – scada system
DATA ACQUSITION- Furnishes status information & measured data to operator.
CONTROL`` - Allows the operator to control the devices e.g. motor operation, circuit breakers, tap changer etc from a remote centralized location.
DATA PROCESSING - Includes data quality & integrity check, limit check, analog value processing etc.
TAGGING - Operator identifies any specific device & subjects to specific operating restrictions to prevent from unauthorized operation.

Functions – SCADA system
ALARMS - Alerts the operator of unplanned events & undesirable operating conditions in the order their severity & criticality
`LOGGING- Logs all operator entries, alarms & selected entries
TRENDING- Plots measurements on selected scale to give information on the trends e.g. one minute, one hour etc.
HISTORICAL REPORTING - To save & analyze the historical data for reporting, typically for a period of 2 or more years & to archive.
