The model was calibrated with acceptable goodness-of-fit between the observed and measured values.

Three types of drainfields were simulated: (1) a pipe-and-stone (P&S), (2) advanced soil drainfields, pressurized shallow narrow drainfield (PSND) and (3) Geomat (GEO), a variation of SND.

A water content-dependent function was used to compute the nitrification and denitrification rates. Experimental data from a mesocosm-scale study, including soil moisture content, and total N, ammonium (NH 4 +) and nitrate (NO 3 -) concentrations, were used to calibrate the model. We simulated the fate and transport of N in different types of OWTS drainfields, or soil treatment areas (STA) under current and changing climate scenarios, using 2D/3D HYDRUS software.

OWTS rely on physical, chemical and biological soil processes to treat wastewater and these processes may be affected by climate change. Nitrogen compounds cause eutrophication, depleting the oxygen in marine ecosystems. History of changes in HYDRUS 2.x - History_H3D_2xx.Most of the non-point source nitrogen (N) load in rural areas is attributed to onsite wastewater treatment systems (OWTS).History of changes in HYDRUS 3.x - History_H3D_3xx.pdf (42 kB).History of changes in HYDRUS 5.x - HYDRUS_History.pdf (200 kB).HYDRUS 5.x Technical Manual (1D) (3 MB).HYDRUS 5.x Technical Manual (2D/3D) (4 MB).This is a DEMO version, the full version is available in ELIS However, you can look at results of some prepared examples and try out almost all functions of HYDRUS GUI. The demo version does not allow you to run calculations and save data. Here you can download installation programs for HYDRUS demo versions.
