I have volumetric water content (in soil) data collected from 4 different sites over a period of a month and I need to check whether the 4 sites are different in water loss/ evaporation. Is there a standard method to calculate that and compare the four sites?
you should use reference area or reference measurement for the sites that you want to took samples.
but what do you mean by period of time long period or short one?
you mean find time series data for evapotrspiration used in model
it may helps you
regards
Your question is complicated. Evaporation of soil water depends on soil factors such as texture, structure and previous moisture; But also topographical factors such as orientation, which affects the internal temperature of the soil, and atmospheric, such as air temperature, vapor pressure or wind. To which must be added the water consumption of the vegetation.
I am agree with Francisco, it Is complicated due to many parameters (discribed n'y Francisco) but you can add also mineralogical parameters : for example clay mineral some familly like smectite have a water layer so you have an increase of the water content but this water Is not available for vegetation. Bioturbation can modified the water transfert.
