El relieve de la quebrada Cay, monta?osa en su mayor parte favorece la ocurrencia de procesos de remoci?n en masa, condici?n que se ha manifestado debido a los cambios de cobertura y uso del suelo. En la ciudad de Ibagu? se presenta problemas de agua debido a que los afluentes de captaci?n presentan turbiedad y ya que la quebrada Cay surte en parte de recurso h?drico a la poblaci?n, ha obligado al sistema de abastecimiento a garantizar el continuo servicio por el incremento exponencial en los habitantes. La metodolog?a consisti? en una descripci?n de las zonas afectadas por inestabilidad en la cuenca, identificando los par?metros morfom?tricos de la microcuenca utilizando las herramientas SIG por medio del software ArcGIS 10.3, se identificaron ?reas de amenazas; dise?ando una clasificaci?n de riesgo ubicando sectores que puedan ser propensos a remoci?n, bas?ndose en caracter?sticas del terreno; seguido a esto con visitas de campo se corroboro las presuntas zonas y en caso de existencia de remoci?n, se dise?? un modelo de bioingenier?a utilizando herramientas de suelos con el programa Slide Rocscience. Para desarrollar la investigaci?n se plante? como objetivo general dise?ar obras de bioingenier?a en las ?reas de riesgo de la quebrada Cay, como objetivos espec?ficos se identific? las ?reas de remoci?n de masa y se defini? la t?cnica de bioingenier?a seg?n las caracter?sticas morfom?tricas de la micro cuenca Cay. Como resultado se identific? un talud que en su corona presenta una carretera; sector que es propenso a remoci?n, el cual se propone ser intervenido con un gavi?n verde, cumpliendo como metodolog?a de bioingenier?a, el cual se le fue realizado los chequeos correspondientes de verificaci?n cuantitativa del mejoramiento.The relief of the hilly Cay, mountainous for the most part, favors the occurrence of mass removal processes, a condition that has been manifested due to changes in coverage and land use. In the city of Ibagu? there are water problems due to the fact that the tributaries have turbidity and since the Cay falls partly from the water resource to the population, it has forced the supply system to guarantee the continuous service due to the exponential increase in the inhabitants. The methodology consisted in a description of the zones affected by instability in the basin, identifying the morphometric parameters of the microbasin using the SIG tools through the ArcGIS 10.3 software, areas of threats were identified; designing a risk classification locating sectors that may be prone to removal, based on terrain characteristics; Following this, field visits corroborated the presumed zones and in the case of removal, a bioengineering model was designed using soil tools with the Slide Rocscience program. To develop the research, the general objective was to design bioengineering works in the risk areas of the Cay Creek, as specific objectives were identified the areas of mass removal and the bioengineering technique was defined according to the morphometric characteristics of the Cay basin. As a result, a slope was identified that has a road in its crown; sector that is prone to removal, which is proposed to be intervened with a green gabion, complying as a methodology of bioengineering, which was made the corresponding checks of quantitative verification of improvement.
