Ecohydrology has the potential to make a significant contribution to the global need for improved water resources management. An investigation was conducted into educational and capacity building activities related to ecohydrology in an effort to better integrate understanding, promote awareness of existing activities, and to recommend action for global knowledge translation. Based on a survey of key partners and a review of the literature, three key observations were made: 1) consistency in the use of the definition and key concepts behind ecohydrology must be achieved, 2) development of a framework for courses in ecohydrology be developed for application on a regional and global scale and 3) there may be existing educational materials on ecohydrology but they are not well publicized or accessible even to seasoned practitioners. These recommendations are currently being implemented with the development and testing of three pilot courses.

Late spring/summer depth and velocity conditions of 16 ‘functional habitats’ were investigated in lowland rivers. The habitats significantly associated with shallower, faster areas were 'submerged, fine-leaved macrophytes' (20-40 cm deep, >0.45 ms-1) and 'macroalgae' (10-30 cm, >0.60 ms-1). 'Cobbles' were associated with slightly slower, shallower conditions (0-20 cm, 0.45 ms-1), 'gravels' with slower conditions again (around 0.15 ms-1, depths from 0-30 cm). The slowest velocity class (0-0.05 ms-1) was associated with 'silt' (depths 20-70 cm), ‘marginal plants' (0-20 cm deep), 'emergent macrophytes' (10-80 cm deep), 'submerged, broad-leaved macrophytes' (40-110 cm deep), 'floating leaved macrophytes' (40-150 cm deep) and a second mode of ‘macroalgae’ (145-180 cm deep). The factors thought to be behind these findings are discussed.
