This is one problem I encountered in the research. Now my groundwater model has 3 layers, representing acrotelm, catotelm and mineral soil respectively. The 1st layer (uppermost) is an unconfined layer with no question. But what about the 2nd? Is the permeability of mineral soil much less than that of catotelm? Besides, what if the water level is below the top of mineral soil level? Can I consider it unconfined layer then?
But Bouwer's (1978) description of unconfined aquifer is "[t]here is no clay or other restricting material at the top of the groundwater, so that groundwater levels are free to rise or fall." Thus the mineral soil under peat can be considered as unconfined aquifer when the watertable is below its top.
Hi,
回复删除Sorry to be off topic, but I had noticed you had blogrolled my wordpress.com blog. I'd like to point out that it doesn't contain the most recent posts of mine. You can hop over to my blog of 1st preference @ http://princeoflightning.blogspot.com to get your hands full on the latest posts!!
Anyway, you've got some nice content here especially about equity (I work for a BFSI company so I found that interesting).
Cheers,
Vineet Reynolds.
A book maybe useful on environmental modelling theories:

My quota for borrowing books is reached so I have to leave this for future reference.
