Pore size distribution

A discussion forum for RETC users. RETC is a program which can be used to analyze the soil water retention and hydraulic conductivity functions of unsaturated soils.

Pore size distribution

Post by Sara Vero » Mon Jul 15, 2013 2:49 pm

Hi,
Is it possible to obtain a measure of the pore size distribution using RETC or Hydrus, and if so how would I go about this?
Many thanks,
Sara

Sara,

You do not need RETC or HYDRUS to get you a pore size distribution. Such information is directly in the retention curve, since the pressure head corresponds to a certain pore size (radius). Larger pores are empty and smaller pores are full (of water). You can find this information in most Soil Physics textbooks.

I’m currently hiking in Sierra and thus do not have my books currently available.
