Pict. 31. Sedimentation from pond of longer life-time on the outer margin of a doline-with-ponor near Dudar Legend: 1. karst depression; 2. water recharge; 3. plant detritus zone with sharp outer margin; 4. plant detritus series; 5. terrain free of plant detritus; 6. maximum horizontal (a) and vertical (b) extension of pond; 7. Dudar village (the zone of plant detritus indicates pond level and its wedging out points to accelerating subsidence of water level) Pict. 32. Sedimentation in flood pond of longer life-time with recharge from meltwater, interior of dolinewith-ponor shown on Pict. 31. Legend: 1. maximum level of pond; 2. colloid rings indicating slower dropping of pond water table (a,-a

); 3. tree trunk detail free of colloids (the conduit opening at the tree roots results in local acceleration of flow); 4. erosion rills (colloid coating marks the influx of fine sediment, colloid rings point to water table subsidence at variable rate)
