Remote sensing as a tool for resource assessment towards the determination of the legal compliance of surface and groundwater use
Expanded Title:The overall objective of this project is to determine the usefulness and applicability of using remote sensing technologies as a tool for resource assessment towards the determination of the legal compliance of surface and groundwater use. This project focuses on the creation of new knowledge and being at the innovative edge of the topic. This study found that in the context of illegal water use, using remote sensing as a tool to quantify water storage may be appropriate in identifying water bodies and generating a fair estimate of volumes stored. The application of the water balance equation to the G10K catchment did not determine the level of legal compliance of water users to legislation. However, new methodologies, untested in South Africa, were applied to the study area with many challenges encountered. There is much hope that, as remote sensing technology develops and remotely sensed data becomes available at a higher spatial and temporal resolution, the full potential of these models will be able to be fully tested and if proven accurate, could possibly be used operationally in the future. In addition, if the uncertainties and limitations encountered in the course of the research project are considered and acted upon, it is may be possible that at least parts of the methodology may be relevant at a later stage for water use determination. The uncertainties, limitations and challenges encountered during this research project can be categorised into four sections: 1) the accuracy, availability and accessibility of input data, 2) heterogeneity of the study area, 3) skills shortage at supervisory level in South Africa, and 4) computer resource intensive models and software. The anomalies in the WARMS database also made it difficult to compare water use and storage results to the registered values.
