“…The topography of major rivers was also assumed to be incorrect, but was proved correct or at least possible in the investigated cases (Székely, 2009). Finally, a lake of several hundred km 2 shown on the map in a nowadays dry lowland was spectacularly traced by a major flood and thus confirmed (Timár et al, 2008b). Of course, the result of such an investigation is not always that all the features are correct.…”

“…Most such studies deal with 1-2 centuries, based on surveys with known mathematical and geodetic backgrounds (Ziliani and Surian, 2012;Craciunescu et al, 2010;Comiti et al, 2011;Bravard, 2010;Gimmi et al, 2011). In some countries where older cartographic records are also well preserved, it is possible to span 500 or even 800 yr, with spatial accuracies sufficient for quantitative analysis (Longhitano and Colella, 2007;Bondesan and Furlanetto, 2012;Timár et al, 2008b;Székely, 2009;Armas et al, 2013;Kovács, 2010). This means that it is common for map-based historic hydrology studies to reach back in time to the Little Ice Age, which ended around 1850 A.D in Central Europe (Brown, 2003).…”

Abstract. Socio-hydrology is the science of human influence on hydrology and the influence of the water cycle on human social systems. This newly emerging discipline inherently involves a historic perspective, often focusing on timescales of several centuries. While data on human history is typically available for this time frame, gathering information on the hydrological situation during such a period can prove difficult: measured hydrological data for such long periods are rare, while models and secondary data sets from geomorphology, pedology or archaeology are typically not accurate enough over such a short time. In the first part of this study, the use of historic maps in hydrology is reviewed. Major breakthroughs were the acceptance of historic map content as valid data, the use of preserved features for investigating situations earlier than the map, and the onset of digital georeferencing and data integration. Historic maps can be primary quantitative sources of hydro-geomorphological information, they can provide a context for point-based measurements over larger areas, and they can deliver time series for a better understanding of change scenarios.In the second part, a case study is presented: water level fluctuations of Lake Balaton were reconstructed from maps, levelling logs and other documents. An 18th century map system of the whole 5700 km 2 catchment was georeferenced, integrated with two 19th century map systems, and wetlands, forests and open water digitized. Changes in wetland area were compared with lake water level changes in a 220 yr time series. Historic maps show that the water level of the lake was closer to present-day levels than expected, and that wetland loss pre-dates drainage of the lake.The present and future role of historic maps is discussed. Historic hydrological data has to be treated with caution: while it is possible to learn form the past, the assumption that future changes will be like past changes does not always hold. Nevertheless, old maps are relatively accessible data sets and the knowledge base for using them is rapidly growing, and it can be expected that long-term time series will be established by integrating georeferenced map systems over large areas.In the Appendix, a step-by-step guide to using historic maps in hydrology is given, starting from finding a map, through georeferencing and processing the map to publication of the results.

“…water management) v povezavi z zajemom, analizo in prikazom prostorskih podatkov so se ukvarjali že mnogi (na primer Schwab et al, 1996;Gregory et al, 2001;Timára et al, 2008). Avtorji ugotavljajo, da je za učinkovito gospodarjenje z vodami potreben celosten pristop, pri katerem se upoštevajo vse prostorske informacije, ki so na voljo, pri čemer imajo veliko vlogo geografski informacijski sistemi in kartografska vizualizacija.…”
