This paper presents a review of the fluvial geomorphology research undertaken on Wales’ rivers. As well as discussing trends seen in these studies, by firstly focussing on the work of geologists of the late nineteenth century, and by progressing through the development of geomorphology as a research field to the present interdisciplinary period, the fields that have received particular attention on Welsh rivers are discussed. These include the evolution of the mega-geomorphology of Wales, innovative process studies, the evolution of alluvial fluvial systems to short- and long-term climatic changes, and the response of Welsh rivers to anthropogenic activity. This range of studies is a result of the nature of Welsh fluvial systems. Firstly, they display an evolutionary history including glacial periods and rejuvenation. Secondly, contemporary processes have created a wide range of channel types, including bedrock channels, gravel bed rivers, meandering, braided, stable and unstable channels. Thirdly, academic interest and pragmatic concerns regarding river management have led to a large body of work that has, in some cases, led to many reaches on Welsh rivers being classed as international archetypes. Gaps in our knowledge are also discussed. These include the need to increase our understanding of contemporary process and to continue the work done on alluvial response and evolution through using the latest techniques to constrain the chronology of fluvial system development. There is a need to extend the spatial scope of our studies to areas which have not received as much attention in the past such as the bedrock and mixed bedrock-alluvial channels of the north-west and the south Wales valleys.

The Welsh language has several features in its grammar which are crosslinguistically very unusual. This paper looks at five such features, at their rarity in the languages of the world and at their place in Welsh grammar. It shows that the textual frequency of each feature, in corpora of spoken and written Welsh, is declining. These five features, which had been stable in Welsh since the earliest records well over a thousand years ago, have in the lifetime of older speakers become optional or obsolescent in the spoken language: the grammar of the language has changed. Welsh is likely changing because of bilingualism. Along with the recent increase in the public use of Welsh has come an increase in the use of English in the everyday lives of Welsh speakers. The average Welsh-speaker now speaks more English than Welsh, outside the family at least. Speaking a second language fluently and regularly HAS been shown to affect the speaker's first language, probably to lessen the psychological load in constantly switching between the two languages. It is argued that in such a situation cross-linguistically unusual features are inherently more susceptible to loss. Finally, the paper looks very briefly at possible future developments.

The paper reports on three epochs of bridge building in Wales. The first period, from Roman times to the start of the Industrial Revolution, was dominated by the use of local materials (stone and timber) by local craftsmen. The second period was an integral part of the Industrial Revolution when new bridge building materials (cast iron, wrought iron and steel) were developed and used in the construction of canal and railway bridges. The third period was associated with the growth of traffic following World War II when concrete and steel became the dominant bridge building materials during the development of the trunk roads and motorways. The paper shows, in simple terms, the fundamental structural engineering developments underpinning these developments as new materials became available for bridge building. In particular, the evolvement of various beam cross-sections, tubes and trusses is discussed. Attention is also given to the significant contribution of four world-renowned bridge builders: William Edwards who built the famous arch bridge at Pontypridd; Thomas Telford who built the Pontcysyllte Aqueduct and the Menai Suspension Bridge; Robert Stephenson who built tubular bridges at Conway and over the Menai Straits and I. K. Brunel who built the unique Chepstow Railway Bridge and the railway timber viaduct at Landore, Swansea. Finally, the paper draws attention to some of the unique bridges of Wales.
