After the investigations carried out (four exploratory boreholes B-1 to B-4) and detailed engineering-geological mapping, a detailed engineering and geological map of the landslide was prepared. Based on the established properties of the landslide (size, volume, type of landslide), the causes and mechanisms of sliding, it was proposed measures of remediation landslide. After simulations on numerical models, using the PLAXIS 2D v8.5 software package, it is suggested to build a retaining wall on the counterfort, making of drainage systems in the form of fish bones and regulation of the roof water and fecal water in the appropriate receiver or drainage system. Keywords Landslide, Sliding, Drainage system, Reinforced concrete wall on the counterfort 1. Introduction In 2014, during the heavy rains, in the settlement Mahmutovići, the municipality of Sapna, a landslide was activated that threatened three residential buildings. Due to slipping, plastic sewer pipes are broken, while the auxiliary dryer is destroyed and moved 40-50 meters from the original location. As a temporary measure of remediation under the houses, nylon is placed that prevents further soaking and sloughing of the soil. To stabilize the terrain, 20 wooden pilots were inserted into the ground. It has been observed that in one of the three buildings there are no gutters, so all the water flows over the surface of the terrain and contributes to the instability of the terrain. 2. Geomorphological, Hydrogeological, and Engineering Geological Characteristics The landslide is located on the hillside with exposition towards the east. The inclination of the hillside is 19° and according to the inclination it is classified into a medium steep slope and according to the form in the concave hillside. Due to the presence of water, it is classified into a little sodden slope with occasional occurrences of diffusion Published online at http://journal.sapub.org/jce Copyright © 2019 The Author(s).

Based on the geological map of Zvornik 1: 100 000 the subject site is located in the part of the terrain that builds the middle Miocene sediments ( 2 M 2 2 ) that represented by sandstones, clays, and marls. Dip azimuth of the sediments is towards the northeast at an angle of 20 0 . Marls and sandstones take part in the substrate structure, while surface deposits built by multicolored sandy dusty clay to marly clay. Surface waters have not been observed in the investigated field. Near the landslide, two wells are registered: the well 1 northeast of the B-2 borehole at a distance of 30 meters and the well 2 southeasts of the borehole B-4 at a distance of 36.7 meters. In the first well whose depth of 3.0m, groundwater is registered at a depth of 30cm from the surface of the terrain while the other well was locked so the water level in this well not registered. The presence of the wells near the landslide indicates that the hillside is watered. To define the geological, engineering and geomechanical characteristics of the terrain, four exploration boreholes were performed. In exploratory boreholes, sandy-dusty to marly-clay, sand, sandstone, and marl were determined. Based on the performed experiments of standard dynamic penetration in boreholes, it has been proven that the compact soil occurs at depths of 1.8 to 3.0 meters. These depths represent the depths to the sliding surface. In the investigated terrain, the geological substrate is represented by a complex of rocks built of marls and fine-grained yellow-green sandstone. The mentioned rocks belong to a group of poorly-petrified rocks that, under the influence of exogenous forces, decompose and form thick clay-sandy blankets with debris. The substrate is at a depth of 1.8 to 3.0 meters. The surface coverings are eluvial-diluvial and colluvial. The
