“…By applying the published interpretations of similar stratigraphic units (e.g., Joeckel, 1989Joeckel, , 1994Joeckel, , 1995Joeckel, , 1999Dalrymple et al, 1992Shanley et al, 1992;Archer et al, 1994;Feldman et al, 1995;Blum and Price, 1998;Posamentier and Allen, 1999;Blum and Tornqvist, 2000) to field observations of the ICS and associated units, a progression of genetic events can readily be developed relative to sea-level change (Figure 9):…”

“…Avulsions are a key process in floodplain construction -the dominant process in many situations -and the stratrigraphy and alluvial architecture in southeast Texas indicates their prevalence throughout (at least) the Quaternary (Waters and Nordt, 1995;Blum and Price, 1998;Aslan and Blum, 1999;Blum and Aslan, 2006;Taha and Anderson, 2008). However, avulsions and the flow networks and valley morphologies associated with them also have important implications for contemporary processes and water and sediment fluxes, as shown in recent studies of the Brazos (Sylvia and Galloway, 2006), Trinity (Phillips and Slattery, 2007, in press) and Sabine (Phillips, in press) rivers.…”

Avulsions -relatively sudden changes in course, or establishment of new anabranches -are an important process in alluvial rivers. Their key role in floodplain construction and alluvial architecture, and the general conditions favouring avulsions, are well known. However, avulsion processes and evolution, and the factors controlling avulsion regimes, are poorly understood. In the southeast Texas coastal plain, where avulsions are common features of the river valleys, avulsions were studied on the lower Brazos, Navasota, Trinity, Neches and Sabine rivers using a combination of aerial imagery, digital elevation models and field surveys. Avulsions have important influences on the surface morphology and contemporary processes in all five rivers. Features associated with avulsions are active and distinct throughout the study area, and all the rivers have experienced geologically (if not historically) recent avulsions. However, no two of the study rivers have the same contemporary avulsion regime. First-order differences in avulsion style are controlled by the stage of valley filling, and within the three rivers characterized by an unfilled incised valley, antecedent morphology associated with late Quaternary and Holocene coastal and fluvial-deltaic processes accounts for the major differences. In the Navasota (27 avulsions in 185 km) and Neches (21 in 340 km) rivers, subchannels associated with avulsions exist in all stages of development from active to infilled, and some have occurred in recent decades. The other rivers have fewer avulsions, but both the Sabine and Trinity have experienced historic channel shifts. Only the Brazos River has experienced no avulsions within the past c. 300 years. Results show that even within a region of similar environmental controls and geological history local variations in inherited morphology can result in different avulsion regimes.

“…The age of the deposits beneath any floodplain is variable (Bull, 1991;Knox, 1996;Blum and Price, 1998;Blum and Tornqvist, 2000). Therefore, the relative age of the terrace surfaces was established for each of the rivers (Fig.…”

In the Priego area, central Spain, extensive tufa deposits are located in three small tributaries located at the head of the 1000 kmlong Tagus River. The deposits are originated after karst-origin running waters emerged from the confines of the canyons and expanded outward. Old tufa deposits of Priego are mainly present as terraced alluvial plain deposits where different autochthonous and allochthonous facies appear. Extraclastic deposits of quartzite and limestone clasts derived from Mesozoic rocks are interbedded with the tufa marking pulsatory high-flow periods. Using the geomorphologic analysis six terraced levels were differentiated and sampled for ostracode amino acid racemization analysis. D/L ratios of aspartic acid and glutamic acid were used for dating purposes. Cluster analysis defined six aminozones (AMI-AM7) which were dated as follows: AMI: 407 ± 12 ka oxygen isotope stages (OIS 11); AM2: 263 ± 14 ka (OIS 7e); AM3: 181 ± 17 ka (OIS 7a); AM4: 136± 13 ka (OIS 5-6); AM5: 108 ± 14 ka (OIS 5); AM7: 11 ± 4 ka (OIS 1), indicating that tufa deposition took place during warm periods. Models of riverine and riverinebarrage tufa accumulation indicate that their maximum build-up took place between the canyon mouth and the point of depletion of dissolved CO 2 , and this affected the elevation of the top of the deposits and their relative chronology.
