1 Developing countries: Practical proposals to overcome common problems Dipl. Ing. Francesco Masola Technical Support Manager Maccaferri Deutschland GmbH
2 Contents The use of DT Mesh in Developing countries 1. Erosion i. Impact on agricultural land and wetlands ii. Impact on Infrastructure 2. Water supply i. Irrigation ii. Sanitation 3. Other structures 4. Common advantages
3 1. Erosion Impact on agricultural land and wetlands Loss of land for cultivation Water management in area (too dry or too wet) Storm surge vulnerability excess sudden erosion asdasd Impact on Infrastructure Limited resources Journey time increases Transportation hazard People movement health / trade / food Community isolation
4 River characteristics River characteristics vary: Climate. The type of soil. The particular location along the river course. Mountain regions Steep gradients (5-10%), High flows, low discharge. Each river is different and therefore requires solutions according to its characteristics. Valley regions Flat slopes (< %), Low flows and high discharges. Mid slope regions Moderate gradients (1-5%), mid flows and discharges.
5 The cause High flows passing over weak surfaces Steep gradients Narrow channels Flash flows / storm surges Critical velocity of the protection required Resistance to abrasion and erosion of the material on the surface influences the rate of damage.
6 Unstable river beds seasonal flooding / flash floods
7 Uncontrolled rill erosion / wetland stabilisation Ref: Piet-Louis Grundling, Working for Wetlands
8 Meandering rivers Critical velocity for fine sand 0.2m/s to 0.5 m/s Transportation of rocks Transportation of stones and pebbles
9 Loss of critical infrastructure Unsuitable scour protection at the base of bridge piers / bank protection
10 Control structures - failure Erosion of culverts
11 Control structures - failure River protection structures are designed for multiple purposes; Day to day control of flow for irrigation, sanitation, supply Additional capacity for flood conditions
12 Solutions Weirs Longitudinal works Groynes Culverts Low-level water crossings 12 Strettamente confidenziale
13 Solutions Mountain region Transverse structures = Weirs and Bank protection Designed to; Reduce river gradient Control erosion Stabilize river bed level Dissipate excess water energy Reduce solid transport Retain water for supply purposes
14 Weir function During flood During normal use During low flow
15 Water retention structures Generally gabion weirs are permeable structures, but when applied geomembrane MacLine and geotextile MacTex behind the weir, they can also serve as water containment structure.
16 Solutions Mid-slope region Longitudinal works aimed to reduce river bed movement which can be braided showing patterns of main flow during severe floods. Longitudinal structures = Weirs, Groynes and Bank protection Designed to; Control erosion Stabilize river bed level Dissipate excess water energy Reduce solid transport
17 Solutions Valley region Mainly longitudinal works to contain the water within its course, thus correcting its pathway as well as providing bank protection. Longitudinal structures = Weirs, Groynes and Bank protection Designed to; Control erosion / meanders / land loss Stabilize river bed level
18 Community involvement Ref: Piet-Louis Grundling, Working for Wetlands
19 Groynes
20 Culverts Van Stadens River Pass
21 Bridge pier protection
22 2. Water Supply Irrigation / Sanitation Management Controlled water flows Settlement ponds Containment structures Ref: Piet-Louis Grundling, Working for Wetlands
23 Irrigation management Delay water leaving catchment More effective use of scarce water Maximise potential growth Ref: Piet-Louis Grundling, Working for Wetlands
24 3. Housing & Other Structures Sand filled bottles as fill to gabions Above, above right: BBC Right: Heinsdorf, Stehr, Naidoo
25 Montana Winery Ian Ritchie: La Terrasson greenhouse 25
26 Gabions as walls 35% voids (traditional rock fill) Air flow through building Cooler inside than out thermal mass of gabion fill Structural consideration column support BDP Archirtects: Film Vaults 26
27 4. Common advantages Social Community involvement Simple to install Empowers local labour Benefits obvious More productive land water controlled Technical Flexible Permeable Easy to transport Local materials to be used wherever possible
28 Community engagement Creating work Teaching skills More self-sufficient communities Reduced need for external support/intervention Ref: Piet-Louis Grundling, Working for Wetlands
29 Flexible Structures Gabion Sack Gabions Reno mattress Flexible Resistance Tensile strength Permeable Structural continuity Low construction cost Excellent integration into the environment. These valuable and positive characteristics make gabion and Reno mattress structures really competitive in the whole field of hydraulic protection works and soil conservation.

34 Transportable: Bundles Flat-packed Easy to transport Filled on project-site
35 Fill types Preferred stone sizes 100 to 300 mm for gabions and 75 to 150 mm for mattresses Always overfill gabions ± 25 to 50mm D= 80mm for gabions D=60 mm for mattresses
36 The smaller sized stones permits improved and more economical filling of the cage and allows better distribution of the imposed loads. 36
