Drainage area and incised valley fills in Texas rivers: A potential explanation

摘要: Abstract The largest rivers draining to the Gulf of Mexico in Texas are at more advanced stages valley filling than with smaller drainage areas, corresponding differences alluvial morphology and architecture, avulsion style. This seems imply that larger fluvial systems either produce sediment relative accommodation space valleys, or they have undergone longer periods aggradation. However, it is not clear these case. paper presents a theoretical analysis showing areas can infilling those (but identical histories production per unit area) due nature scaling relationships between basin area incised size, yield. Data for region shows strong linear relationship width area. nonlinear proportion filled somewhat weaker, but still significant, major deviations readily explained terms local inherited tectonic features. Results show degree stage could occur size alone. indicates caution interpreting fills basins different sizes supply.
