2 Survey Details
2.1 Dates of erosion monitoring survey: (1990-1994) since 1990
2.1 Water/wind erosion? Water erosion
2.3 Area monitored: Upper and middle Orcia river valley, Central Italy 23.000 ha
2.4 Character of area: Pliocene marine fine sediments; distensive tectonics in neogenic basin; badlands erosion forms, gullies, Mediterranean climate
2.5 Frequency of monitoring: Seasonally on field; some years interval photo interpretation
2.6 What fraction of fields in the monitored area were included in the survey? What fraction of fields in the monitored area were included in the survey?
Fields showing erosional forms and mass movements, 2 pilot areas undergoing severe erosion
2.7 How were estimates of erosion made? Terrestrial photogrammetry, DTM techniques, measures on aerophotos
2.8 Were air photographs used? Yes, several, different scale and date flights; Landsat TM (April and September 1987)
2.9 For each erosion site, information recorded: Location, contributing area, topography, morphology (slope length, gradient, elevation, aspect, surface roughness, slope shape), erosion features, soil volume removed, land cover (vegetation, land use), soil type


2.10 Data obtained from elsewhere: Climatic data
2.11 Data calculated from above information: Erosion rate
2.12 Meterological station density and type: 1 fully equipped meteo station (ours); 5 rain gauges (National Network); 1 thermopluviometric (National Network)
2.13 Length of record of meterological data: Variable from 60 to 2 years depending on the station
3. Associated Work
3.1 Associated experimental or plot-based work: Process based studies (TORRI)
3.2 Associated modelling work:
