Project class content:
Content
Scale graphical presentation of waste deposits (plan
representation and transverse-longitudinal sections).
Stability analysis of waste deposits using the initial
condition methods presented in practical class. The
influence of the external factors on the waste deposits
stability (overloads, seismic shocks influence, rocks pore
water).
Waste deposits embankment and earthworks projecting (for
increasing the stability reserve and for ensuring the
agricultural, forest, tree and viticultural rehabilitation
required conditions). The calculation of the needed materials
for the embankment and earthworks.
Waste deposit scale graphical presentation after the
embankment and earthworks. Stability analysis of waste
deposits using the methods presented in practical class after
the embankment and earthworks.
Leveling works projects. The calculation of the needed
materials for the leveling works. The calculation of the
vegetal soil volume required for the degraded terrain
rehabilitation works.
Improvement, amendment and fertilization works for waste
deposits. Choosing the machines needed for the
embankment, earthworks, leveling and vegetal soil deposit
works. Plantation works. The graphic with work times.

Grading Policy:
The students pass the class if he obtains mark 5 (out of 10).
Final mark shares:
- lectures – 60%;
- practical class – 40%.
Minimum required knowledge for obtaining mark 5:
- knowing the degraded terrain types and their degradation reasons;
- knowing and explaining the effects of terrain degradation on the vegetation;
- comparing the terrain stability analysis methods;
- knowing the terrain rehabilitation and remodeling techniques.
Classroom Rules of Conduct:
 Turn off (or place on vibrate) cell phones and pagers during class;
 During exams, the use of cell phones, pagers, PDAs, or any other electronic devices is
strictly.prohibited
