Beyond the site, deep drainage channels appeared to lead to a shoreline in the distance.
In the images returned by the Hugyens to scientists, where do "deep drainage channels" appear to lead? d.
Using a salt-water balance model (SaLF), deep drainage (mm/year) is estimated.
Compared to TPRPS, deep drainage was reduced ∼72 88%, evaporation was lessened ∼83 89% and transpiration was limited ∼6 10% under GCRPS.
We estimated natural discharge (i.e. deep drainage plus evapotranspiration) from water table fluctuations monitored in six (6) piezometers.
The hypothesis was confirmed that arable land constitutes the main source of deep drainage and groundwater recharge in Northeast Germany.
Shrubs also captured drainage losses beyond the effective root depth of annuals and revealed 25 50% lower deep drainage losses than in sole crop plots.
It was also found that the soil dried fastest in the loamy and duplex soils present in the field, which was attributable to deep drainage and preferential flow.
Evaporation fluxes are quantified and compared with other fluxes (precipitation, run-off, deep drainage) affecting soil water content and matric suction.
The underestimation seems to be caused by an unrealistic deep drainage through the soil, whereas the overestimation can be attributed to impervious surface runoff overestimation.
