“…This map (Figure 7) allows us to visualize the spatial distribution of soil erosion risk in the province of Manabí, and also enables us to relate the different risk classes with the factors that have the greatest weight as regards their determination by interest areas (compared by the superposition of the final erosion map onto the map of each of the factors). This has allowed us to identify that the factors with the greatest influence on soil erosion risk are the slope and the soil coverage, thus corroborating the point made by Vulević et al (2015).…”

“…The variables were reclassified into five classes of soil erosion risk, as follows: 1 (very low), 2 (low), 3 (moderate), 4 (high) and 5 (very high). The variables were combined using a weighted ratio, obtained from expert judgment by means of a multi-criteria evaluation (Starkloff and Stolte, 2014;Vulević et al, 2015), and using software for the analysis and interpretation of satellite images and GIS, specifically those related to map algebra. The weighting process of the factors determined the following results: 20% (0.2) for the USLE R factor, 30% (0.3) for the topographic slope, 30% (0.3) for the NDVI, 10% (0.1) for land use, and 10% (0.1) for soil texture, expressed as follows:…”

Soil erosion risk zoning in the Ecuadorian coastal region using geo-technological tools

The activation of erosive processes on the slopes of the drainage catchments in the Ecuadorian coastal region represents a serious environmental problem that results in a loss of soil resources with the consequent reduction in agricultural productivity, an increasing lack of areas with vegetation, and decreased water quality. These issues increase, among other things, the probability of flooding. The purpose of this research is to zone soil erosion risk in the Manabí province, which is located on the Ecuadorian coast. The methodology is supported by the employment of Geographic Information Technologies (GIT) in order to access and process information of interest, such as: precipitation data with which to calculate the R Factor of the Universal Soil Loss Equation (USLE); topography, which was employed to create a slope map from the Digital Elevation Model (DEM) ASTER; vegetation cover, by applying the Standard Difference Vegetation Index (NDVI); land use, through the interpretation of orthophotos and a field survey; and infiltration capacity, obtained by considering the texture of the soil. The factors were combined by means a weighted relationship (map algebra) and exploiting the potential of software for the design of Geographic Information Systems (GIS). The results indicate the presence of soils with little or without vegetal protection, in areas with steep slopes, moderate rainfall and extensive farming activities. These characteristics determine conditions of high soil erodability, and propitiate the triggering of erosive processes. This scenario shows the need for autonomous governments to implement policies, strategies and actions so as to promote the strengthening of institutional and community capacities that will promote environmental sustainability.

The province of Central Java often experiences floods during the rainy season and drought in the dry season. To support the program, BBWS Bengawan Solo participated in building some small-dams in Solo basin watershed. For this plan to be realized there needs to be a preceded study to determine the locations of potential dams. The paper aims to identify potential small-dams in the Solo River Basin, particularly in the Wonogiri District, and to determine priorities for the sequence of development. The potential of the small-dams is roughly derived from public information, topographic maps, and ground surveys. Initially, based on public information and local government officials, 39 locations of small-dams were obtained. After analyzing the topographic map and ground checking, the potential locations were cut down to 13 sites. Five small-dams will be selected as the first priority. The priority is determined based on multiple criteria, which consisted of technical criteria (topography, geology, and hydrology) and non-technical criteria (drought, economy, social and environment). Assessment method was based on the scoring system on all criteria. The result found that the five most potential small-dams in Wonogiri District are Glimbung, Gompyong, Wungu, Weru, and Waru.

Soil erosion tends to occur with rainfall runoff, thus leading to grave soil and water loss. An increase of water content in soil caused by rain makes the loss of matrix suction and the decrease of shear strength obvious, and will promote soil erosion. The soil-water characteristic curve (SWCC) can be used to describe the relationship between the water content and the matrix suction in unsaturated soil. For this paper we studied the SWCCs of the granite residual soils in a collapsing erosion area in Jiangxi Province, China. A GEO-Experts pressure plate extractor was used to measure SWCCs for soils with different dry density, grain size, drying and wetting cycles, and lime content. The initial dry density has a significant impact on SWCC. With increasing dry density, the suction was decreased for the same water content. The larger the grain size, the greater the suction value for the same volumetric water content. Under the same suction, the volumetric water content decreases as the lime percentage increases and water stability improves. SWCCs of the drying and wetting cycle demonstrate the hysteresis phenomenon. The area of the hysteresis loop decreased with the increase of the dry density and drying and wetting cycle number. It also became small when the soils were mixed with lime. In this paper, the Van Genuchten model, the Fredlund and Xing model, and the Gardner model were used to fit the experimental data of SWCCs. The presented fitting parameters show that the residual sum of squares is less than 0.002. All the experimental data fit well to three models for SWCC. The results indicated that the simulated value of the Gardner model does provide best agreement with the measured value. These results will provide an important basis for the further study of the soil collapsing erosion process and soil cover design.
