Overall purpose: • provide representative periodic assessments of the status and

trends in the availability and use of freshwater resources• adequately monitoring the progress along with the European

policy objectives• improve water facts today to facilitate policy decisions and issues

Three main questions to adequately capture the drivers, pressuresand state of freshwater resources are important:• What variables are useful?• What spatial and temporal scales are appropriate?• How to build on existing effort and where to expand?

What is needed ?



Why is it needed ?

• Adequately formulate indicators • Assess the state & trends of the WR and associated pressures• Monitor the progress with European policy objectives• Broader assessment of specific water-related issues in the

relevant conceptual ecosystem frameworks• Assess the impact of specific sectors, driving forces & responses

The information needed in relation to water quantity can generally be described as:

Drivers: natural availability of WR, hydrometeo parameters Pressures: water demand, water abstraction by source & sectorState: assessment of trends by sourceImpacts: ecosystem integrity, use value

Need for more detailed and less aggregated data

Reporting sheet Reporting sheet QNT_SWQNT_SW (3) (3)How should it be reported ?

1. Data on Freshwater Resources Availability

Status and trends in the hydrometeorological parameters and the hydrological freshwater resources budget

Spatial aggregation: RBD level (scaled down to reflect spatial variability of WR and support adequate analysis)

Temporal aggregation: monthly basis (allow distinguishing seasonal patterns and assessing dry periods within a hydrological year, as well as investigating additional indices such as the “Dry season flow index, WRI)

Some additional data will be collected on surface water storage volume for the natural or man-made reservoirs in the RBD, and groundwater levels and storage for the main aquifer systems (comprehensive of the water resources’ availability trends over long-term and deeper assessment of water scarcity issues)

Streamflow data will be also compiled for selected gauging stations on a daily time step (provide a more complete national picture and assess additional hydrological trends, such as flood patterns, changes in the 7-day low flow etc.)

How should it be reported ?

2. Data on surface water & groundwater abstractions @ RBD level

• enhance the assessment, complimentarily with the OECD/Eurostat work, by including the aspects of seasonality, temporal and spatial variability

• Annual assessments at national level do not reflect regional trends and patterns…

thus a regionalization at RBD level is required, and a monthly scale analysis is needed to accurately capture the evolution of water abstractions by source and sector

Water Resources Availability

Streamflow at selected gauging stations_Specifications:Daily data for the representative gauging stations (minimum of 10 years continuous measurements is desirable). Each representative GS and year should be described by a set of summary statistics (mean, maximum, mean annual minimum flow (MAM), etc.)

Representative GS: such as downstream stations at the main catchments and main tributaries. Stations may also be selected to describe natural flow such as stations unaffected by reservoirs or water abstractions. One GS/1000 km2 may be used as an indicative density
