• Talud Stabilization of Bird House Residential in Manaus City
  Abstract Slope stabilization techniques have been increasingly used in the field, mainly due to high market values for land in large urban centers. With this, the technical feasibility study guarantees the application of the best solution for each case. From this context, we sought to verify the best method of containment by means of a case study according to the parameters of soil resistance, cohesion and angle of friction at the residence Morada dos Pássaros in Manaus - AM. The methodology used was of an exploratory nature with a case study, where in the first phase the topographic survey of the study area was carried out. In the second phase, it was sought to plan the location of the holes, according to ABNT NBR 8036 (1983). for the accomplishment and technical follow-up of the investigation of the soil in the place by means of the test of percussion to the percussion - SPT and in the 3º phase was characterized by means of physical and mechanical laboratory test with the collection of material. Considering the collected data, it is noticed that the soil is with 3% of plasticity, concluding that a soil with plasticity below 7% loses the capacity to be molded and to become brittle. Therefore, it is concluded that the best technique to be used is geosynthetics, both in cost and in soil absorption, due to the feasibility of redistribution of stresses and slope deformations.

• A proposal for sustainable surface drainage on hard floors
  The Brazilian population, during the wetter periods, has faced great difficulties of locomotion in the urban roads due to the accumulation of water on the surface, considering that the areas of natural infiltration (soil) are being increasingly scarce through a process called soil sealing. This is due also through the intense process of urbanization, particularly in the formation of metropolitan regions, have been generated many problems of urban infrastructure, especially in relation to drain rainwater. The volume of water collected by the urban drainage network is dropped directly into rivers and streams, causing the water table decrease considerably. A solution is found the addition of thinning in the gutters so that there is a decrease in the flow sluice gates, and also that increase the permeability or renaturation. The new system adopted will solve the problem of waterproofing of urban roads, since it will have the function of collecting the waters coming from the surface runoff and throwing directly to the ground, making a balance in a sustainable way. Keywords: Renaturalization, permeability and flow.
