Short description of the project:
A section of the main project concerned with the revitalisation of the culturally significant yet environmentally damaged landscape around Moritzburg. During the project, fauna, flora, building substance, water usage and land use were analysed in order to decide the optimum recovery plan and preservation measures for the valuable biotope and a natural park containing ponds and small lakes for fish farming.
The focus of the water balance investigations was to design the most appropriate measures for reinstating the landscape in its historical setting and to be able to predict the consequent effects of this revitalisation. The main lake, the Venus Well and an artificial canal were prime features of the investigations. Once data was available as to the complete hydrological situation within the area, the current water balance for the catchment area around the main lake was calculated with the help of the AKWA-M model. Within the ponds of the park the flow regime is dictated by the fact that the water is primarily needed for fish farming. The procedures of draining and filling of the ponds was likewise taken into account.
A qualitative analysis of the matter balance was undertaken to complement the quantitive section of the water balance observations. This was carried out by investigating the hydrochemical / biological parameters over the period of a season. We tried out various scenario based calculations in order to determine the practicality of reintroducing historically true methods for water damming and the consequent changes which this would incur for the fish farming.
As for the Venus Wall and the artificial canals, we researched their historically documented, current and potential water supply capacities; we measured their respective geometry and calculated other hydrodynamic factors in order to be able to best reinstate and maintain the well and canal.
