Extending from the flat slab buttress and multiple arch buttress dam designs, the contiguous buttress design entailed a thickening or widening of the upstream edges or heads of the buttresses in effect joining them together, thereby making them contiguous.s a result, this type of dam is also referred to as an Ambursen dam. Ambursenâs flat slab buttress dam design took advantage of the stabilizing effect of the vertical water load on the strongly inclined upstream face that required a minimal buttress thickness per unit of dam length.
