| Description du jeu de données | |||
| Résumé | Results of erosion measurements performed by Birte Junge in the years 2001 and 2002 near three villages in the Upper Oueme catchment, notably Dogué, Serou and Awanla.Three different measurements methods were used (erosion nails, erosion parcelles, sediment traps) and finally the potential (longterm) erosion was quantified according to the universal soil loss equation (USLE). Parameter, Attribute list: surface runoff, soil loss, potential soil loss, P factor, K factor (erodability), C factor, R factor, LS factor. Dataset created by IMPETUS subproject A2. No information about Data Lineage; No information about Data Consistency; No information about Data Completeness; No information about Positional Accuracy; Data Completeness: Details can be found in Junge (2004), The experimental setup for the the erosion parcelles showed several errors in the first year (2001), There only the results from the year 2002 should be used, Erosion measurements were performed only during one or two rainy season, Considering the hgih rainfall variability this is not enough to obtain reliable amounts of soil erosion, Nevetheless the measuements are very useful for comparisons of soil erosion between different cropping systems and the natural savannah | ||
| Strategie d'observation | The major objective of the study were to compare the soil loss amounts for different landuse and cropping systems in three villages in the Upper Oueme catchment and to estimate the potential erosion rate according to the Universal soil loss equation (USLE) for local conditions in the Aguima catchment. | ||
