Remote sensing of water quality in inland waters requires reliable retrieval algorithms, accurate atmospheric correction and consistent method for uncertainty estimation. In this paper, the GSM semi-analytical inversion model is modified for inland waters to derive inherent optical properties (IOPs) and their spectral dependencies from air and space borne(More)
: Geo-ICT plays an increasing role in the management of spatial processes at different levels ranging from local to global scale. A world wide scientific and professional community develops and implements tools and methods to deal with these issues. Furthermore new business and Geo-ICT environments are emerging which force GI-providers to develop new(More)
– This paper discusses results of application of five erosion models with low input data requirements to a semi-arid mountainous catchment in the Bolivian Andes. in a semi-quantitative manner by overlaying the predicted spatial patterns obtained by the models with an erosion intensity map derived from comparison of an ortho-photo mosaic (1961) with a recent(More)
The identification of nitrate-nitrogen (NO 3 –N) origin is important in the control of surface and ground water quality. These are the main sources of available drinking water. Stable isotopes (15 N and 18 O) for NO 3 –N and along with a 1-D reactive transport model were used to study the origin and processes that lead to nitrogen transformation and loss in(More)
