“…The sediment record shows that this process actually started much earlier than is apparent from the maps (Kadlec et al 2009, Grygar et al 2010. The neglect continued until the second part of the 19th century and the beginning of the 20th century.…”

“…Such channels can be recognized in the exposed sections of eroded river banks along the River Morava. Two such channels, dated by 14 C to mediaeval times, have been found in the northern part of the study territory, and are about 2 m deep and 10 m wide (Grygar et al 2010; today's channel is much larger, see Table 1). In terms of earlier runoff, this means that:…”

“…Today, the bed of the main Morava channel is incised 6 m below the floodplain surface on average. Locally it is incised down to the sandy gravels that underlay fine-grained overbank deposits dated to the early and middle Holocene (Kadlec et al 2009, Grygar et al 2010. The study of floods in the Strážnické Pomoraví region over the past 130 years requires that changes in the primary influencing factors, such as land use, climate and civil engineering, has to be taken into consideration.…”

“…Only in 1912 and 1936 was the peak annual water stage below 310 cm. This implies that sedimentation in the river floodplain may have been relatively continuous and undisturbed before its modification and regulation, which is an important presumption in the use of floodplain sediments as a palaeo-environmental archive in the Strážnické Pomoraví area (see also Kadlec et al 2009, Grygar et al 2010.…”

The development of the River Morava floodplain has been influenced by several natural and anthropogenic factors. This paper focuses on variations in flood activity and channel changes of the River Morava in the region of Strážnické Pomoraví (southeastern Czech Republic). Floods are analysed in terms of measured peak water stages, H k (Rohatec, 1886(Rohatec, -1920 and peak discharges Q k (Rohatec/Strážnice, 1921 evaluated with respect to their N-year return period (H N or Q N ). The frequency of floods with Q k ≥ Q 2 reaches a significant maximum in March, followed by July. According to flood series compiled from 1881 onwards, their frequency peaked in the 1961-1970 decade with the most severe events occurring in July 1997 (Q 100 ), March 2006 and June 2010 (Q 50 ). During the study period the natural dynamics of the original anabranching channel patterns were significantly modified by human intervention, such as the abandonment of some anabranching channels, channel straightening, enlargement of the main channel, flood-dike construction, and the creation of the Bat'a shipping channel. These changes resulted in decreased frequency and a reduction in the extent of floodplain inundations compared to the period prior to channel modifications in the 1930s. Q 50 ). Au cours de la période, les dynamiques naturelles d'écoulement du lit original en tresses ont été profondément transformées par l'intervention humaine: abandon des lits en tresses, redressement et élar-gissement du lit principal, construction de digues contre les crues, et création du canal de navigation Bat'a. Ces changements ont eu pour résultat de réduire la fréquence et la zone d'expansion des inondations dans la plaine par rapport à la situation qui prévalait antérieurement à la canalisation de la rivière dans les années 1930.Mots clefs inondation; transformation de la plaine d'inondation; transformation du lit fluvial; lit anastomosé; région de Strážnicke Pomoraví; Rivière Morava

Alluvial and colluvial deposits were investigated at prehistoric tells close to the Bosna River. The chronology is based on ten radiocarbon ages, five optically stimulated luminescence ages, and on the archaeological record. Fluvial activity of the Bosna River is indicated by overbank fines [ca. 5000 (±1000) BC, 500 BC until today] and a phase of lateral displacement of the river bed with subsequent channel fills ca. 2000–500 BC. Early Holocene fluvial activity was probably triggered by climatic variability but might have promoted the expansion of Neolithic societies into the Visoko Basin. Mid‐ to late Holocene river activity occurred under increased climatic aridity but coincided with the expansion of prehistoric settlements to a wider area of the river basin on hard rocks in the adjacent mountainous areas. The destruction of the thin soil cover in the mountains is discussed as a probable trigger for enduring subsequent river activity. This is also indicated by a change in the geochemical signature of the alluvial sediments. The proposed mechanism might explain the mid to late Holocene river history in other regions. The potential of geochemical analyses and diachronous high‐resolution archaeological records to make inferences regarding sediment sources and geomorphological processes is demonstrated.
