13 Particularities of Drain Liquid in the Small Wetland of Braila …

Fig. 13.15 Anti-erosion network of synthetic material
Banks and channel drains will need to be protected against erosion due to the
level changes occurring during pumping as well as to prevent clogging of the water
pump sorb with alluvial or vegetal materials. Anti-erosion networks are provided as
a system for preventing and controlling inclined surfaces, made up of tear-resistant,
low-elasticity polyester stacked meshes, arranged between them to obtain a threedimensional volumetric configuration.
These networks have the role of fixing the soil and fostering the development of a
continuous vegetal carpet. They can be made of high-density polyethylene (PEID),
polypropylene or polyester, 2% carbon black for ultraviolet protection, antioxidant
additives, and 0.25–0.75% lubricants. They generally have large chemical inertia,
which is practically inert and does not affect the hydric or terrestrial environment in
any form. The open and volumetric structure allows fixing of the slopes, ensuring an
increase in the friction angle. Also, high tensile strength and low creepage provide
long-term reinforcement of the slope (Fig. 13.15).
13.4.3.1 Reservoirs Locations
Taking into account the potential fire risk in the Small Wetland of Braila, seven
locations for some lakes have been identified, which can be used as reservoirs for
depositing and delivering water for putting out the vegetation fires. These locations
will be named reservoirs and they are numbered from 1 to 7 from upstream to
downstream. They can also be turned into fixed sources of collecting and pumping
the water with minimum building works (deepening the lake basins if such is the
case, putting up a motor-pump, building access roads used for extinguishing fires).
At the same time, in choosing the location, we took into account the strict protection
of the two areas from the Small Wetlands of the Braila reservation, and they have
not been equipped with reservoirs (Fig. 13.16).
