CIR airphotos from 1980 show drastic changes of the 
terrain surface. Almost all of the depressions (gravel pits) 
which constitute the base of todays waste dump and 
which were registered on the aerial photographs of 1968 
were totally filled with waste. From the main entrance the 
thickness of the waste grows in southeastern direction up 
to a distance of about 700 m. 
Towards the railway bridge (Fig. 1) there is a more recent 
waste dump, of 400 x 570 m°. Near the road bridge 
another new waste site had developed. Its size is 
approximately 380 x 280 m°. New active gravel pits were 
observed. 
Aerial photographs from 1981 have also been analysed 
and showed a further spreading of the waste dump in 
southeastern direction. Waste has also been deposited 
along the Sava riverbank, all the way to the railway 
bridge. There was also spreading in a southeastern 
direction from the bridge. 
The 1989 aerial photographs at a scale of 1: 4650 clearly 
show the borders of the waste dump, which were at that 
time already adjacent to the village of Jakusevec. In 
addition, a Sava backwater, which in 1980 was still 
outside the northeastern border of the dump, was now 
almost completely covered with waste. The southeastern 
portion of the waste dump was now connected with the 
northwestern portions and they formed a single big mass. 
Waste was mainly deposited in the central area. That 
year, the dimensions of the waste dump were around 
1400 x 470 m°. 
Near and thermal infrared images of the waste dump 
have been analysed, too. There three portions of the

waste dump can be identified: a southeastern, a central, 
and a northwestern portion. This is probably a result of 
different thickness and compositions of the waste and 
different decomposition rates. Aerial thermograms taken 
in 1974 by a DS-1250 multispectral Daedalus scanner 
show increased thermal anomalies in comparison to the 
surrounding area. Some parts of waste dump were very 
pronounced. 
3.3. Waste quantities 
The quantities of waste deposited on the Jakusevec 
waste dump between 1968 and 1989 has been 
determined by photogrammetric measurements on 
airphoto stereomodels using a Leica BC-3 analytical 
stereo plotter and Aviosoft software. The volumina of the 
waste have been calculated by means of digital elevation 
models (DEMs), taking the original landscape level at 104 
m above sea level. 
The data obtained by the measurements and calculations 
result in the following table:
