   Three-dimensional models are available for raised mires situated in parallel-sided troughs or with circular or elliptical margins (Ingram, 1992). All the models indicate that taller raised mires containing taller ground-water mounds will be found in circumstances that promote greater moisture surplus and hence greater recharge, or where discharge is impeded because catotelms have lower hydraulic conductivities.
