Toolbox: a summary of case studies around the world about
water management. It is being continuously updated.

(III WWF)
The largest conference of the world on water management,
next meeting in Japan march 2003.

Demand Results
Demand results cover requirements by and allocations to demand sites. The following reports are available:
Annual Water Demand
The annual requirement at each demand site, before distribution losses, reuse and demand-side management savings are taken into account.
Monthly Supply Requirement
The monthly requirement at each demand site, after distribution losses, reuse and demand-side management savings are taken into account.
Supply Delivered
The amount of water supplied to demand sites, listed either by source (supplies) or by destination (demand sites). When listed by destination, the
amounts reported are the actual amounts reaching the demand sites, after subtracting any transmission losses.
Unmet Demand
The amount of each demand site's requirement that is not met. When some demand sites are not getting full coverage, this report is useful in
understanding the magnitude of the shortage.
Coverage
The percent of each demand site's requirement (adjusting for distribution losses, reuse and demand-side management savings) that is met, from
0% (no water delivered) to 100% (delivery of full requirement). The coverage report gives a quick assessment of how well demands are being met.
Cost of Delivered Water
The cost of delivering water to demand sites, listed either by source (supplies) or by destination (demand sites).
Demand Site Inflow and Outflow
The mass balance of all water entering and leaving one or more demand sites. Inflows (from local and river supplies) are represented as positive
amounts, outflows (either consumed or routed to wastewater treatment plants, rivers and local supplies) as negative amounts.
Supply and Resources Results
Area
Inflows: Water entering the area (river headflows, surface water inflows to reaches, groundwater recharge, local reservoir inflows, other local
supply inflows).
Outflows: Water leaving the area (consumption at demand sites, evaporation on river reaches and reservoirs, losses in transmission links,
losses in wastewater treatment, and outflows from the end of rivers and diversions).
Note: Inflows to area may not equal total outflows from area due to changes in storage.
River
Streamflow: The streamflow at selected nodes and reaches along a river. You can plot a line for each point on the river over time (choose Year
for the X Axis), or a line for each month plotted along the river (choose River Nodes and Reaches for the X Axis).
Flow Requirement Coverage: The percent of each flow requirement that is met, from 0% (no water flowing) to 100% (flow requirement met or
exceeded).
Groundwater
Storage: The aquifer storage levels at the end of each month.
Inflows and Outflows: A mass balance of all water entering and leaving a specified aquifer. Inflows (from recharge, inflow from river reaches,
and return flows from demand sites and wastewater treatment plants) are represented as positive amounts, outflows (withdrawals by demand
sites and outflows to river reaches) as negative amounts.
Overflow: Groundwater overflow occurs when the aquifer storage is at its maximum, and there is net inflow.
Reservoir
Storage: The reservoir storage levels at the end of each month.
Inflows and Outflows: All water entering and leaving a specified reservoir. Inflows (either from upstream (river reservoirs) or monthly inflow
(local reservoirs) or return flows from demand sites and wastewater treatment plants) are represented as positive amounts, outflows (to
downstream, evaporation, or withdrawals by demand sites) as negative amounts.
Hydropower: The power generated by reservoirs and hydropower nodes.
Transmission Link
Inflows and Outflows: Includes amounts lost to evaporation and leakage.
Other Local Supply
Inflows and Outflows: A mass balance of all water entering and leaving a specified other local supply source. Inflows are represented as
positive amounts, outflows as negative amounts.
Return Link
Inflows and Outflows: Includes amounts lost to evaporation and leakage.
Environment Results
Environment results cover pollution generation by demand sites, pollution loads at receptors, and wastewater treatment.
Pollution Generation
Pollution generated by each demand site.
Pollution Loads
Pollutant loads carried by return flow links from demand sites and wastewater treatments (sources) into rivers and local supplies
(receptors).
Pollution Inflow to Treatment Plants
Total pollution flowing in to wastewater treatment plants.
