Robert Dickinson posted a discussionHow is the St Venant Equation Solved for in the Dynamic Wave Solution of SWMM 5?
Subject: How is the St Venant Equation Solved for in the Dynamic Wave Solution of SWMM 5? An explanation of the four St. Venant Terms in SWMM 5 and how they change for Gravity Mains and Force Mains. The HGL is the water surface elevation in the upstream and downstream nodes of the link. The HGL for a full link goes from the pipe crown elevation up to the rim elevation of the node + the surcharge depth of the node. The four terms are: dq2 = Time Step * Awtd * (Head Downstream – Head Upstream)…See More

"Ciao Andrea, grazie per il suggerimento. Sono stato fuori per lavoro ma ora mi rimetto a studiare il software. Se dovessi avere qualche dubbio mi permetterò di disturbarti ancora.
Saluti.
Alessandro"

In sostanza prendo le curve di possibilità pluviometrica calcolate con Gumbel in base alle serie storiche, e ricavo lo ietogramma di progetto per alcuni tempi di pioggia (la scelta dipende dalle caratteristiche di corrivazione del bacino).
Non compilo le time series direttamente nel software, ma creo tanti files .dat tanti sono i tempi di pioggia che intendo modellare. LI edito con excel e hanno forma del tipo:
03/11/2009 00:00 341.6
03/11/2009 00:01 341.6
03/11/2009 00:02 341.6
che ad es. rappresenta uno ietogramma rettangolare per una durata di pioggia di 2min di intensità pari a 341 mm/hr.
Nei dati del rain gage utilizzo come Rain format - Intensity e come Time Interval - 0:01 (ovvero il minuto).
Questo come impostazione di massima.
Ciao,
andrea
