The watersheds of Faddal, Fettouh and Takamout rivers are all located in the great Tizirene unit. The latter shows fields marked by a rugged topography and a heterogeneous and contrasted lithology, composed of sandstones and soft and plastic formations, which are exposed under humid climatic conditions that increase with hypsometry. This coastal area of the central Rif becomes a site of several socioeconomic activities, increasingly populated and crossed by main communication routes. The slopes in this area usually suffer of slope instabilities that cause substantial damage and a very high maintenance cost. In order to assess the type of instability mechanisms affecting these slopes of heterogeneous formation, representative sites of the Rifian Mediterranean coastal area was chosen. A wide inventory of mass movements (MM) was performed, with the reporting of the existing lithology, fracturing, elevation, aspect, slope degree, land use and stream network. All these layers data have been jointly used for characterization of MM mechanisms in the study area. It is shown that the Mediterranean coasts of central Rif represent an identical functioning for the entire area between the Bokkoya and Beni Bouchra massifs, a distance of approximately 40 km.

The seasonal energy requirements and fuel consumption for heating purposes in residential buildings are influenced by the architectural design, construction materials characteristics, meteorological temperature measurements, internal gains and air exchange rate of the building. The goal of this study is to assess the thermal performance and environmental impact of residential buildings' in Morocco taking into account all these factors and considering two sources of energy: liquefied petroleum gas (LPG) and electricity. The study concludes that the heating energy requirements for the prototype building vary between 2 and 253 kWh/m2.year depending on localities, glazing type, glazing area percentage, the internal gains and the air exchange rates. The electricity consumption is 2.6 times greater than that of LPG in terms of kg oil equivalent, and by using LPG instead of electricity the emissions of greenhouse gases can be 3.4 times reduced. © 2014 © 2014 Taylor & Francis.

In the western part of Morocco, various studies deal with land use (LU) mapping and analysis. However, no quantitative or qualitative analysis has been focused on the interrelations between mass wasting (MW) and LU. This paper is centered on the mapping in the NW Morocco (Chefchaouen province) to define different LU classes and their consequences for slope stability. Seven classes of LU were mapped: dense forests, shrubs or matorrals, reforestation areas, farmlands, naked areas, urban zones and free water bodies. Four major types of MW occur within this region: landslides, rock falls, debris flows and undercutting. Badlands (BL) do not belong to MW but are characterized by successive thalweg and crests resulting from linear erosion, also responsible for the loss in farmlands. Therefore, their location and extension are analyzed. The analysis of the spatial distribution of MW according to LU classes demonstrated that high densities of MW and BL classes cover three main LU classes: farmlands include 45% of MW and BL; dense forest's areas reach up to 24% of the phenomena, commonly due to an important local clearance of vegetation; shrubs are concerned by 11% of the MW only, in conformity with the discrete character of their plant cover. Landslides, river undermining and badlands are mostly triggered by farmlands. Debris flows and rock falls develop where steep rocks and resistant formations (limestone, sandstone, and quartzite) dominate, in association with marquetry of shrubs and islands of dense forests.
