Abstract
This paper reports on a number of advances in the hydrologie characterisation of farm dams that are required in the assessment of farm dam impacts on streamflows. While the characteristics were derived for input to the TEDI simulation model, the generic nature of the information derived is applicable to any quantitative analysis of farm dam impacts, regardless of the method used. The use of topographic maps and aerial photography to identify the number and volume of farm dams is discussed, and this includes development of a functional relationship between farm dam surface area and volume. An essential component required for the estimation of farm dam impacts is the proportion of a dam’s volu..
