Hello to everybody,

I am trying to assess the vulnerability of any water body to be
polluted through surface runoffs passing agriculture areas. I am
trying to consider the effect of the soil permeability to do this. I
have been looking for information about the soil in this place, and I
have only found edafology information about the dominant soil and the
soild type.

So, the soils found in this place are:

II: Igneous Rock, intermediate igneous - Andesite, trachyte,
phonolite, diorite-syenite
S01: Sedimentaty Tock, clastic sediments - Conglomerate, breccia
SC: Sedimentaty Tock, clastic sediments - Conglomerate, breccia,
sandstone, greywacke arkose, siltstone, mudstone, claystone, shale,
ironstone.
UC: Unconsolidated, colluvial
UL: unconsolidated, lacustrine

dominant soils:

CLl: Luvic Calcisols
CMe: eutric cambisols
CMx: Chronomic Cambisols
LVh: Haplic Luvisols
LVk: Calcic Luvisols
LXh: Haplic Lixisols
PHl: Luvic Phaeozems
VRe: Eutric VErtisols


Could anybody tell me if I can relate in a broad way (high, medium,
low) the permeability of these soils using this information?

Thank you very much!

The best thing to do is to measure the hydraulic conductivity (permeability)
with a
infiltrometer (permeameter). www.soilmoisture.com has some information
about
equipment.
