A. Introduction
Gully erosion has been recognized as an important environmental threat throughout the world affecting several soil and land functions. There is ample physical evidence of intense gully erosion occurring at various times in the past in different parts of the world. Gullies are one of the few sources of morphological evidence in the landscape of past phases of erosion reflecting the impact of environmental change (land use, extreme climatic events).
Gully erosion represents a major sediment source although gully channels often occupy less than 5 % of a catchment. The development of gullies increases runoff and sediment connectivity in the landscape, hence increasing the risk of flooding and reservoir sedimentation. Assessing the interactions between environmental change (land use, climate) and land degradation remains a key issue for environmental scientists, land managers and policy makers.
Over the last decades, significant progress has been made in understanding gully erosion and its controlling factors. However, many research questions relating to gullying mechanisms, human impact on gully erosion, gully control measures etc. remain and these represent major challenges for the scientific community. Jean Poesen identified the most significant contemporary challenges during the last International Symposium on Gully Erosion held in April 2010 at Lublin, Poland (Poesen, 2011). Several of these are highlighted below:
- The need for more detailed studies of historical gullies, in particular of environmental and socio-economic conditions leading to their formation, development, and sometimes to their infilling;
- The need for better use of process-based knowledge about contemporary gully development to explain historical gullying and gully infilling. Many gully studies have focused on gully incision and gully widening processes but very few studies address gully infilling.
- What are the appropriate measuring techniques for monitoring and experimental studies of the initiation and development of various gully types at various temporal and spatial scales? In

addition, both more applications of new technologies to detect gully systems and medium to long-term monitoring of gullies are needed to better understand gully erosion processes.
- Modelling the incision, development and infilling of gullies, and validation of the models in different environments;
- Prediction of gully erosion rates; - What are topographic thresholds for gully head development and for channel infilling? - What are the most effective and efficient gully prevention and gully control measures? The 6th International Symposium on Gully Erosion (6th ISGE) 2013 continues the
sequence of successful meetings held in Leuven (Belgium, 2000), Chengdu (China, 2002), Oxford (USA, 2004), Pamplona (Spain, 2007) and Lublin (Poland, 2010). The city of Iasi located in the Moldavian Plateau of Eastern Romania has about 400,000 inhabitants from which over 60,000 are students (Figure 1).

Land degradation has been recognized as an important environmental threat in the Moldavian Plateau of Eastern Romania. This area of extensive farming extending about 27,000 square kilometers is one of the most severely degraded agricultural areas in the country in the form of soil erosion, gullying and landslides accompanied by deposition in the reservoirs or

along the valley-bottoms. Among these processes and landforms most of the present-day gullies are scenic and active (Figures no. 2, 3, 4, 5).

This symposium targets all scientists undertaking research on gully erosion and embraces national and international studies and established newly initiated investigations. The objectives of the Symposium are to communicate exciting scientific developments, to identify current gaps in knowledge and to discuss ways in which soils and land can be better managed to meet the challenge of protecting environment against the impacts of climate change and increased human-induced pressure.
Given your research interests, we would encourage you to contribute an oral or poster presentation to the 6th ISGE in 2013. The organisers are keen to see a wide range of work and approaches represented in the hope that this will stimulate discussion, the development of new ideas and increased collaboration within this important area of research.
Please visit the “www.gullyerosion2013.com” web page regularly for new information regarding this symposium. Please bring this information to the attention of other colleagues who may be interested.

Abstract
Land degradation has been recognized as an important environmental threat in the Moldavian Plateau of Eastern Romania. This is an area of extensive farming where land degradation in the form of rill - inter-rill erosion, gullying and landslides is accompanied by deposition in both the reservoirs and along the valley-bottoms. Nine reservoirs within seven catchments and other six basins were selected for investigation. These small catchments are tributaries of the Barlad and Elan basins and their size does not usually exceed 10,000 ha.
The study aims to evaluate the mean recent sedimentation rates in the basin floor of the discontinuous gullies, in the reservoirs, and on the floodplains. Three main areas of monitoring discontinuous gullies were explored: classical leveling work, repeated survey through a particular close stakes grid and the Caesium-137 technique. By period leveling over previous iron check-plates deployed on the gully basin floor it was possible to monitor sediment deposition. The Caesium -137 technique was
7
also used in the reservoirs and on the floodplains to get information on dating specific levels of sediments and documenting erosion/sedimentation rates.
Results have indicated that over the last half of the century the mean deposition rate was 4.4 cm yr-1 for short successive discontinuous gullies. The higher precipitation on record over 1963-1986 (especially 1968-1973) was associated with 5.2 cm yr-1 mean deposition while the rate of 2.7 cm yr-1 was estimated after 1986. As for the floodplains, the estimates are in the range of 1.3–9.3 cm yr-1. The estimated sedimentation rates in the reservoirs located in two geomorphologic subunits are averaging 7.0 cm yr-1 in the Tutova Rollling Hills and 3.0 cm yr-1 in the Central Moldavian Plateau, respectively. Main changes in land management, especially arising of the up-and-down hill farming since 1991 caused significant increase in erosion/sedimentation rate in comparison with the previous conservation farming.
