## 5 Conclusions  
The equations that were present in Table 8 were appropriate for soils present in the \"El Garrochal\" sector, in Southern Quito, which was composed of mostly organic material. The organic material presented in this type of soil is composed of a mix of decomposing organic materials, wooden roots, and inorganic soils, but in less quantity. Therefore, it was necessary to adapt the DMT equations to obtain correlations that better approximate the natural in situ conditions of soft soils. However, it is important to talk about the individual results, which must compare them not only with the values obtained from correlations, but it is also important compare them with laboratory test results. The most discussed parameter in this type of research was the undrained shear strength (\(C_{u}\)). Figure 17a showed that this parameter assumed values between 0 and 15 kPa, being the most critical zone between meters 2 and 7, with \(C_{u}\) less than 10 kPa of each well. Equation (6) showed a similar behavior in this section, taking conservative values without overestimating them; however, the values that were obtained by [PERSON]'s equation presented high values. Hence, the original [PERSON] equation had to be modified to consider the organic character of the material, and for this reason, [PERSON]'s work provided better results in mineral soils [39]. As with the undrained shear, the modulus of elasticity obtained by Equation (3) provided values that were closer to those obtained in the laboratory (Figure 22), estimating better this parameter in organic soils. Therefore, because of the close relationship between \begin{table}

**Parameter** & **Units** & **Description** & **Equation** \\ \hline \(E\) & MPa & Elasticity Modulus & \(E=1.191z^{-0.881}\) \\ \(C_{u}\) & kPa & Undrained Shear Strength & \(c_{u}=19.548z^{-0.523}\) \\ \(\rho\) & g/cm\({}^{3}\) & Density & \(\rho=1.413z^{-0.127}\) \\ \hline \hline \end{tabular}

Table 9: Summary of equations obtained as a function of depth. these two parameters and the complexity of organic soils, it is worthwhile to carry out studies on this type of material. In addition, [PERSON], et al. (2019) [40] corroborated that [PERSON]'s expressions overestimated the undrained shear value in organic soils, showing how [PERSON]'s nomogram provided a bad classification of organic soils and does not allow for finding adequate density values. This can be verified in Figure 28, although the in situ density did not have a defined trend given the composition of the material, the nomogram provided data that did not reflect the conditions of the material in its natural state. Although Equation (9) had an erratic trend, it allowed for obtaining data more following the natural state of samples. The density in this organic soil ranged between 1.00 and 1.60 g/cm\({}^{3}\); it is important to use this range and consider its variable behavior to understand why it is important to obtain low-density values [4]. As a summary, the equations obtained (Table 8) complement the work proposed by [PERSON], who was responsible for providing an adequate method for the study and determination of parameters in soft soils, such as those found in this work. However, it is important to adapt [PERSON]'s equations according to the soil types present in each region. The equations provided in Table 9 were considered an additional contribution to this research; however, it is recommended to complement this research specifically to determine the influence of depth on the deviation of the results obtained. Finally, the importance of obtaining accurate parameters for this type of soil was due to its poor mechanical properties, which hinders its use in construction projects.
