conduction, and in-channel damming) in this study. Two non-parametric statistical methods, Mann-Kendall and Pettitt test, were employed to detect the long-term changes in the time series of water discharge and sediment load (1959-2002) at the annual, monthly
and seasonal scales. The impacts of precipitation variation and human activities on water discharge and sediment load were discerned and quantified using double mass curve and linear regression methods. The operation of reservoirs and hydropower stations
is considered to be responsible for the observed increasing trends of water discharge in the dry-season and decreasing trends of sediment load after 1986, and for the latter, reforestation program in the catchment is another contributing factor. The distinct
seasonal changing patterns of both water discharge and sediment load in this study highlight the importance of involving monthly or seasonal time series in the change detection in hydrological data.
The article deals with EU water framework directive, the lowland rivers, the hydromorphology, the bed load sampling, typology of watercourses and hydropower. Our research examines if the classification of the Fintau as a sand dominated lowland river
The aim of this study is to use data data on wood loads from headwater streams in La Selva Biological Station in north-eastern Costa Rica to examine potential differences in wood dynamics between temperate and tropical headwater streams
. The variables wood diameter/flow depth, stream power, the presence of backflooding, and channel width/depth are consistently selected as significant predictors by statistical models for wood load. The results along with the spatial distribution of wood
with respect to the thalweg, suggest that transport processes exert a greater influence on wood loads than recruitment processes.
The impact of environmental changes on the sediment loads of Norwegian rivers
The aim of this paper is to discuss some examples where detailed measurements of the sediment load have been made during extreme events. A selection of rivers representing the range of sediment yields and processes in various parts of Norway has

This paper describes the dominant bed load transport circulatory pattern over the tidal channel confluence as well as the scour hole genesis and evolution in Bahía Blanca estuary, Argentina. In addition, the AA. detail the bed morphology associated
To identify the internal pollution load of Dianchi Lake it is necessary to evaluate its sediment accumulation. Sedimentation rates of Dianchi Lake are determined by Cs 137 dating. However, Cs 137 vertical distribution in sediment cores of Dianchi
and the lakebed area of each section is calculated. It is necessary to evaluate the gross sediment accumulation of the lake in order to identify evolutionary stages of the lake and load of its internal pollution sources. Therefore, this study evaluates gross
