[ I ] This study uses time series analysis to examine long-term stream water nitrate concentration records from a pair of forested catchments at the Coweeta Hydrologic Laboratory, North Carolina, USA. Monthly average concentrations were available from 1970 through 1997 for two forested catchments, one of which was clear-felled in 1977 and the other maintained as a control. The time series were ...

Covering one of the most important areas in the country, vit: the Central State os S.P., it provides crucial support to Civil Defense in a highly populated region and is intensively explored by the country ́s most important productive sector. In 1992 an S-Band Doppler radar substituted for the original non-coherent C-Band. BRU has just undergone a substantial upgrade/update which significantly i...

Catchment management requires modelling for compliance, investigation, understanding, knowledge capture, and informing decisions. The nature of the problems is variable, ranging across scales both temporally and spatially, including discrete events, long term averages, daily and seasonal dynamics, point and spatial estimates and total catchment outputs. These requirements have spawned a variety...

Three new Sperchon species are described from the Mangde Chhu river catchment area in central Bhutan. indicus Kumar, Kumar and Pesic, 2007 is synonymized with S. gracilipalpis Lundblad, 1941. reported for first time

The following Arena papers in this issue of River Research and Applications present the first of two sets of papers that address the current development status of Mesohabitat Simulation system (MesoHABSIM) and Target Fish Community approach. It includes a description of the methodology, results of testing and validation and example of application. I am excited to deliver this publication into t...

Hydrological, hydrodynamic and water quality models are often used to simulate surface water in a correct way to be a good basis for decisions regarding the development and management of water resources. Molenbeek is one of the main tributaries of the River Dender basin (Belgium). The hydraulic model is implemented by using the MIKE 11 software of the Danish Hydraulic Institute (DHI). It is a v...
