The Nuovo Adige model is a hydrologicaI model:

working in continuous; with real time data acquired from database; fit to simulate low water periods on the whole basin; calculating water balance; built on international standards (CUAHSI, OPENMI).

FLEXIBLE

A system that can evolve in time if new demand are manifested

FLEXIBILITY from modeling point of view means allowing new models integration, by the way the knowledge of dynamics increases or new numeric methods are defined, with no change on EXTERNAL system structure (i.e. Implementing “plug-ins” method)

GLOSSARY

• CUAHSI - Consortium of Universities for the

Advancement of Hydrologic Science (representing

more than one hundred United States universities)

provides web services, tools, standards and

procedures that enhance access to more and better

data for hydrologic analysis. CUDAM is CUAHSI

international member. Nuovo Adige is developed

upon consortium specifications.

GLOSSARY

• OPENMI - I a set of specification for models integration. Originally developed in the HarmonIT EU project (DHI and Wallingfort software, among others).

All model OpenMI compliant can be connected and used

GLOSSARY

• PostgreSQL/PostGIS is an Open Source relational database including geographic extensions (i.e. the management of geometric features)

• Arc Hydro, is the database archietecture adopted by CUAHSI as base of its hydrological data management system.

Database (PostgresSQL/PostGIS/CUAHSI)

Netnode related to network and basins

Time series are linked to monitoring points:

• Geometries insertion;

• Positioning of cross sections;

• Lake intersections;

• Computation of water withdrawal;

• Time series updating.

Tools have been developed to managing insertion and creation of geometries and time series data, necessary to models’ run:

GEOMETRIES INSERTION

• Copying geometries from shapefiles to database tables; • Extracting topological nodes from net geometries;• Creating links between different geometries (nets, net nodes,basins).

POSITIONING OF CROSS SECTIONS

• Finding intersections between network and CROSS sections;• Computation of new nodes progressive distance, and network updating;• Copying new informations to analysis tables.

LAKE INTERSECTIONS

• Finding intersections between network and lake geometries;• Labeling intake nodes and outtake nodes;• Copying new node informations to node tables.

COMPUTATION OF WATER WITHDRAWAL

• Evaluating maximum available discharge to withdrawal, for different destination uses and different time periods.

TIME SERIES UPDATING

• Rewriting input file to SQL;• Linking time series to related monitoring points;• Creating new metadata.

Models (UNITN/OpenMI)

The approach to hydrological modeling is different for peripheral zones

of Adige basin, where natural outflow is preponderant, and for main

river channels where instead is fundamental to consider artificial

works: Basin peripheral area: a Rainfall-Runoff model (called GEOcuencas) is

used; Main river: a 1D routing model is used for discharge evaluation,

counting both natural and artificial intakes and withdrawals, if there

Geomorphological runoff model

Hydrological modeling data automatically extracted from DB are:

geometries (network structure) time series (hydrometers and weather stations) withdrawals data reservoirs data

The hydrological model can be run in any of the critical points in the basin:

• nodes: points in basin like: hydrometers, artificial reservoirs, lakes, points where you

want to evaluate discharge; macrobasins: areas marked by drainage divides and a node, o located between two

consecutive nodes; basic basins: basic hydrologic unit; with surface < 2 km2.

Models (UNITN/OpenMI): the digital watershed

Geometries for model execution are created for any single simulation, thanks to a

hierarchical numbering scheme, based on Pfafstetter numbering scheme (Verdin and

Verdin, 1999).

Models (UNITN/OpenMI): dynamic database

In this way one can extract upstream elements, starting from current net Pfafstetter

number, so you can navigate the whole network and build related basins. Then

macrobasins are created, closed on the node selected by the user for current

simulation.

Modelli (UNITN/OpenMI): network geometries creation

Models (UNITN/OpenMI): selecting closure nodes

Meteorological data used by models are: rainfall temperature pressure moisture wind velocity solar radiation

These data are evaluated on basic basins.

Meteo Forcing Needed and Managed

Meteo Forcing

Distributed model splits any basic basin (max area 5 km2) in altitude

layers and bands; evaluates stored rain water depth and possible snow melting;Create a filter between measured rain water and hydrological model,

modifying model input

Runoff

•Routing model solves Saint Venant equations, and sets the

required hydrodynamic 1D parameters;Numerical integration of 1D model uses difference finite

scheme;The initial condition is given by uniform flow upon the whole

domain;Boundary conditions are defined upstream/downstream

depending on flow regime;Generic cross sections could be used;Intakes and withdrawals are evaluated;
