Hello SWMM-Users,

EPA has made available Lew Rossman's SWMM 5.2.2 on https://www.epa.gov/water-research/storm-water-management-model-swmm.  Please check the updates file but here are the Engine Updates:

1.  Long run times occurring when the simulation duration exceeded the end of an externally applied time series were eliminated.

2.  A bug introduced in 5.2.0 causing the math expression evaluator to compute a*b^c as (a*b)^c instead of a*(b^c) was fixed.

3.  A check was added to the dimensions supplied for the Modified Baskethandle and Round-Rectangular cross sections to insure that the computed height of the rounded portion does not exceed the total height.

4.  Additional performance statistics were added to the Street Flow Summary table in the project's report file.

5.  The warning messages removed in release 5.2.1 about raising a  node's maximum depth and adjusting a conduit's elevation drop were restored.

6.  The values reported for storage unit evaporation and exfiltration loss as a percentage of total storage volume were corrected.

7.  The default number of threads used for dynamic wave flow routing was changed to 1 to be consistent with the User's Manual and with the GUI.

Also on EPA's web page is a link to the external Dstorm web page https://gcc02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.openswmm.org%2FTopic%2F32275%2Fdstorm---a-design-storm-wizard&amp;data=05%7C01%7Csimon.michelle%40epa.gov%7Cd0b2d598d5684727797808dad3de61aa%7C88b378b367484867acf976aacbeca6a7%7C0%7C0%7C638055249343941960%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&amp;sdata=V2emB5Cft1aeXIyHuHRpz%2FSIW3CditnI2ulnvr5ehx8%3D&amp;reserved=0 ,  which is a non-EPA product.

Thanks to all who commented back to EPA on the webpage, to  me directly, (simon.m...@epa.gov), or to the SWMM-USERs List Serv on SWMM 5.2.1.

Please check out 5.2.2 and let us know what you think.

Buenas tardes!

Soy profesor y con los estudiantes estamos modelando una red de alcantarillado pluvial con SWMM y nos encontramos con la siguiente problemática, a la cual no le encuentro una explicación ni se cómo corregirlo. 

Les cuento:

1) Se modelo la red de alcantarillado para un lluvia de 1 hora de duración y distintas recurrencias (2, 5, 10 y 10 años), con un Sistema Superior de calles y un Sistema Superior de conductos.

EL PROBLEMA: al agregar las calles, por ejemplo, el caudal de descarga final disminuye considerablemente.

Les envio el inp e imagen por si alguien tiene la gentileza enorme de querer observarlo y darme alguna idea o explicación del motivo de estos cambios. 

NOTA: les envio el inp CON y SIN CALLES córranlo para TR5 años y anótense el caudal pico en la salida (Qmax=5.11cms). Luego borren AL MENOS 3 TRAMOS DE CALLE y observaran como el caudal en la descarga comienza a aumentar (Qmax=6.29cms).

Insisto, para 5 años de recurrencia, no hay escurrimiento por calles.

¿Tienes idea de cual es el problema? ¿Cual es la explicacion de esta inconsistencia? 

Ojala me puedas ayudar.

Saludos cordiales,

Pablo
