In the structural-tectonic sense, the terrain is a part of the 
Sava Depression, which is distinguished by its complex 
structure and composition. The basic characteristics of 
the structural relationship is block structures resulting 
from radial tectonics (Velic, 1983). 
On the satellite images, faults of various intensities and 
spreading directions are observed. Amongst them the 
most noticeable ones are those which surround the Sava 
Depression (the Medvednica-Kalnik Fault, the northern 
Sava Depression Fault, and the fault that stretches along 
the Vukomericka Gorica - the Southern Depression 
Fault). Also important is the transcurrent fault which. 
trends from Dugo Selo in southwestern direction. Inside 
the depression many small, less important faults were 
detected (Fig. 3) which determine the block structure. 
Among the lateral faults the most pronounced ones are 
those striking in the directions Zadvorsko-Maksimir, 
Lukavec-Drenje and Rugvica-Kuce. The most significant 
meridional spreading fault is the one that runs from 
Podsused over Rakitje to Rakov Potok. 
The Jakusevec waste dump is situated inside the Zagreb 
epicenter area, i.e. in the immediate vicinity of the source 
of possible strong earthquakes which can result in 
deformations in the soil along the fault zone with a 
magnitude ranging from a few centimeters to several 
decimeters. In addition, the waste dump is located on an 
area in which the Sava used to flow before it was 
regulated. You find many small ,buried" backwaters and 
meanders in its vicinity. They are in most cases 
sediment-filled and overgrown by vegetation and easily 
detectable in aerial and satellite images (Fig. 4).

Multitemporal Landsat TM images (1984, 1990, 1992) 
have been used for classifications of the wider area 
around the waste dump site with ten important terrain 
categories. Comparsons of images from different dates 
show changes that have occurred between the two dala 
takes. Also, a merged Landsat TM and SPOT p image 
has been used to map old river channels and meanders 
as well as the hydrographic net, which is manifested 
through the surface and near-surface moisture content. 
3.2. Analysis of waste dump growth 
Waste transport to the Jakusevec waste dump began in 
1965. The earliest aerial photographs available stem from 
1968 and have a scale of 1:18750. Based on these 
images it was tried to map the terrain relief before the 
waste depositing. It is a rather devastated terrain with 
numerous depressions resulting from gravel removal and 
also a few lakes in the old gravel pits. Small quantities of 
waste were only observed in two locations. The 
dimension of the one closer to the Sava dam were 
approximately 200 x 100 m? whereas the smaller one 
was only 80 x 40 m2. 
Airphotos from 1977 show a spreading of the waste dump 
into northwestern and southwestern direction along the 
Sava riverbank, the total length now being around 1400 
m, the total width approximately 350 m.
