INTRODUCTION Afforestation activities in the Lower Mississippi River Alluvial Valley (LMRAV) are currently peaking after the past four decades of extensive deforestation (Allen 1997, King and Keeland 1999, Stanturf and others 1998). Different forces drive the afforestation efforts of public resource agencies, conservation organizations, private corporations, and private landowners. Their intere...

A long-term study of four degraded streams in the upper Owens River watershed documented the recovery of riparian habitats and significant improvement in channel morphology in response to grazing strategies, recreation management, and pre-irrigation peak flows. Increased control of livestock distribution, timing of forage use and degree of forage utilization on and near stream banks was designe...

We quantified how rates of stream channel migration in a montane meadow vary as a function of the riparian vegetation community. The South Fork of the Kern River at Monache Meadow, located in California’s southern Sierra Nevada range, supports two distinct types of vegetation: a dry meadow community dominated by sagebrush and non-native grasses (xeric scrub and meadow), and a wet meadow communi...

Pteridophyta plants as plant communities in biodiversity have important ecological functions rivers and human life. One of the habitats for ferns upper reaches river Bengkulu is Pasmah River. The River a source water people its surroundings. To maximize role river, it necessary to make an inventory around one which ferns. This study aims determine diversity types variations pteridophyta sorus. ...

When the Yellow River flows through Hetao Plain in Inner Mongolia, north China, it forms a mountain-river-desert system with Yin Mountains on one side and Hobq desert other side. In this system, dense growth of green grass is formed area fronting river mountains at back, however, opposite river, has an inherent trend to lost moisture, which might cause desertification. This study verifies theor...

The objective of this study is to assess the variation of pollution in the Thai-Laos Mekong associated with seasonal dynamics concomitant with the natural geological features and human activities that impact on the adverse quality of the river. The complex ecology of the 1500 km stretch of the Thai-Laos Mekong River has been studied in this paper to understand the relationship with the geomorph...

Phosphorus loss from bank erosion was studied in the catchment of River Odense, a lowland Danish river basin, with the aim of testing the hypothesis of whether stream banks act as major diffuse phosphorus (P) sources at catchment scale. Furthermore, the study aimed at analyzing the impact of different factors influencing bank erosion and P loss such as stream order, anthropogenic disturbances, ...

The rate of bank retreat was measured using erosion pins on the alluvial banks rivers in Podhale region (the boundary zone between Central and Outer Carpathians) during hydrological year 2013/2014. During winter half-year (November–April), mainly caused by processes related to freezing thawing ground (swelling, creep, downfall). summer (May–October), fluvial mass movements such as lateral erosi...

Heavy metal concentrations were investigated in the overbank sediments in the middle reach of the regulated Odra River, in south-west Poland. Samples of sediments were taken in 20 vertical profiles to a depth of 70 cm at 1–20 cm intervals. Regulation and lateral stability of the river channel for over 150 years enabled to follow the decrease in depth of the Cu and Pb concentration peaks across ...
