“…With the advent of remote sensing, it has been possible to prepare this dynamic resource map at various levels of confidence. However, the application of multi-spectral classification techniques in extracting vegetation classes has been inconsistent because of similarities in spectral responses (Bocco and Valenzuela 1991;Adinarayana et al 1994a). The problem is more serious with the digital techniques under heterogeneous hilly terrain.…”

The watershed is the natural planning unit in modelling and monitoring of the effect of watershed management policies. To ensure optimum and sustained productivity through scientific planning, the watershed needs a decision-making information system which involves an appraisal of agroecological characteristics, resource limitations and potential of the watershed for resource development. This complete information helps in generating an information system for watershed management, a Watershed Management Information System (WATMIS). This paper describes an approach to develop a WATMIS for a river basin in the difficult, semi-arid mountainous terrain of the Indian Peninsular region. The methodology includes compilation of various watershed resource data (maps, space and ground-based systems); development of Geographic Information System-based models for soil erosion evaluation; and formulation of a treatmentoriented land-use planning scheme with multidisciplinary knowledge-based rules. A priority sub-watershed delineation survey carried out in the watershed indicates significant variation in sediment yield index values. This calls for conservation planning in cases of high and very high priority sub-watersheds. This systems approach, which is hopefully fast and cost-effective, without individual bias, is related to the optimization of natural resources while minimizing the impact on the watershed environment. This paper envisages some future studies for watershed management strategies.

“…Some studies have been carried out wherein a Geographic Information System (GIS) was used for the determination of the potential for soil erosion in different plot size areas (Bocco & Valenzuela, 1988;Omakupt, 1989;Jurgens & Fander, 1993;Jain & Saraf, 1995;Dutta et al, 1995). A GIS technique, however, is best suited for quantification of the heterogeneity in the topographic and drainage features of a catchment (Schumann, 1993;Schultz, 1994;Beven, 1989).…”

A method has been developed in the present study for the determination of the sediment yield from a catchment using a GIS. The method involves spatial disaggregation of the catchment into cells having uniform soil erosion characteristics. The surface erosion from each of the discretized cells is routed to the catchment outlet using the concept of sediment delivery ratio, which is defined as a function of the area of a cell covered by forest. The sediment yield of the catchment is defined as the sum of the sediments delivered by each of the cells. The spatial discretization of the catchment and the derivation of the physical parameters related to erosion in the cells are performed through a GIS technique using the Integrated Land and Water Information Systems (ILWIS) package. Estimation de l'exportation de sédiments par utilisation d'un SIGRésumé Dans cette étude une méthode d'estimation de l'exportation de sédiments d'un bassin utilisant un SIG a été développée. La méthode repose sur une dicrétisation du bassin en mailles dont les caractéristiques d'érosion du sol sont uniformes. L'érosion de surface de chacune de ces mailles est routée à l'exutoire du bassin en utilisant le concept de fraction sédimentaire exportée, définie comme fonction de la surface de maille recouverte par la forêt. L'exportation de sédiments du bassin est définie comme la somme des sédiments fournis par chacune des mailles. La discrétisation spatiale du bassin et la détermination des paramètres physiques relatifs à l'érosion dans les mailles sont réalisés grâce à une technologie fondée sur les SIG utilisant le logiciel ILWIS (Integrated Land and Water Information).
