Why arcswat 2012 does not give give output for infiltration and evaporation from reservoirs?

31 March 2016 1 7K Report

Hi all,

Greetings. I am modelling a catchment using Arcswat 2012 with many floodplains which i consider as reservoirs in the model. I have calculated all characteristics of reservoirs (floodplains) and the simulated discharge seems fine as the reservoirs clearly have an influence on the peak discharges. However when i look at the output file i noticed the following:

TILE FROM IMPOUNDED WATER = 0.000 (MM)

EVAPORATION FROM IMPOUNDED WATER = 0.000 (MM)

SEEPAGE INTO SOIL FROM IMPOUNDED WATER = 0.000 (MM)

OVERFLOW FROM IMPOUNDED WATER = 0.000 (MM)

When I increase the hydraulic conductivity to 1mm/hr, it give the same output as above.

Could someone explain to me where i have gone wrong? I am using Arcswat2012 (version ArcSWAT 2012.10.2.17).

your input was not a problem. All the outputs were related to impounded water. the water impounded on surface means after meeting the all loses such as evaporation, seepage and overland flow the water gets accumulated on the surface. hence nothing wrong in your output.
