The characteristic group of loess relief in the western part of the Lublin Upland makes up a unique and varied landscape that is particularly attractive for tourists. Gullies, whose density exceeds 11 km/km2 in the Kazimierz Dolny area, are the best known element of the loess landscape. Along the gullies, tourist and interpretive trails have been established, but there is a lack of well-prepared geotourism trails. The southern part of the study area, the Urzędów Hills, is particularly underdeveloped in terms of tourism. This study presents the key characteristics of loess relief in the western part of the Lublin Upland, the current development of tourist infrastructure, and prospects for geotourism based on the unique landforms in the area. A few geotourism trails focusing on the unique loess relief features have been proposed, and attention has been drawn to threats to these landscape assets posed by certain forms of adventure tourism and problems related to private land ownership.

Repeat photography offers a valuable tool for assessing gully erosion development over the past 140 years in North Ethiopia. From a dataset of 57 repeated historical photographs that display gully cross-sections, this study demonstrates that a gully incision phase took place in the second half of the 20th century. At present, thanks to the successful implementation of soil and water conservation measures, most gullies are stabilizing.

Sediment transport along erosion gullies in flysch badlands under Sub-Mediterranean climate is presented. Presented are weekly measurements, compiled measurements by months, as well as correlations of sediment transport with selected weather data. Sediment transport was measured up to 19 kg m-2 and was largely dependent on special weather conditions.

In semiarid regions with low rainfall, poorly developed soils and marly lithologies, land abandonment leads to an increase in soil erosion and degradation processes. In some cases, the initiation of piping processes and the emergence of gullies takes place not long after its abandonment.

The object of this study was to compare and quantify carbon sequestration and erosion control in two type soil and three land uses. Direct measurements of sediment retained in dams with mesh and branches have been taken. In conclusion it may indicate that these dams are an efficient filter control on gully erosion, which is higher in cropland. The capture of organic carbon was higher in natural vegetation due to higher content of organic matter in soil.

In semiarid regions, the main purpose of afforestation has been to provide a protective vegetative cover in order to prevent or reduce soil erosion. This paper shows the results of a study carried out in some areas afforested in the 1970s, in steep slopes and mostly in marls. Afforestation where performed using terraced with subsoiling, so the existing scrub vegetation was removed and Pinus halepensis was planted. The main conclusion is that human action developed in this semi-arid territory, perhaps because the technique applied was not the most suitable for afforestation, has led to the geomorphological activation of the slopes and the emergence and large development of gullies.

The area occupied by gullies and ravines in Murcia Region is 161,028 hectares, representing 14.63%. The origin of these erosive forms are related to several factors such as : lithological and stratigraphic features, mineralogy and geochemistry of the sediments, tectonics, climatic characteristics, low vegetation cover and poorly developed soils.

Gullies developed on sandy lithologies are scarce. Such landforms have developed in the sandy deposits of the Cretaceous 'Utrillas' facies within the Segovia province of Central Spain. They appear at the slopes of a group of mesas and cuestas located at the edge of the northern piedmont of the Guadarrama Mountains of the Spanish Central System. The activity of the different geomorphic processes acting in these gullies, as well as their connectivity, are being characterized and quantified. This study was preceded by reconnaissance methods, whereas presently technologically advanced and more accurate techniques are being utilized. The new methods are applied in an experimental catchment (1.26 ha). They include: i) an automatic Reid-type (formerly termed Birkbeck) slot bedload sampler for continuous monitoring of bedload flux and for continuous sampling of bedload; siphons for sampling the suspended load; and a Parshall flume to monitor water discharge. Jointly, these instruments allow to study the fluvial dynamics at the catchment mouth; ii) topographic surveys undertaken by a Terrestrial Laser Scanner (TLS) to quantify the activity of gravitational, overland flow and fluvial processes in different sediment source areas within the gully basin; iii) micro runoff and erosion plots to monitor the infiltration and erosive response of different Hydrologic Response Units (HRU) comprising the interior of the catchment. This ensemble of novel methods has started providing patterns of sediment movement within the gully system.
