The food and feeding habit of beardless barb, Cyclocheilichthys apogon (Valenciennes, 1842), from family Cyprinidae was investigated by stomach content analyses of 374 collected fish in two consecutive reservoirs Temengor and Bersia Reservoirs which are separated by Temengor Dam. The main aim of this study was to compare the stomach contents of C. apogon between these two reservoirs in wet and ...

Summer typhoons and spring snowmelt led to the riverine spread of continental Fukushima fallout to the coastal plains of Northeastern Japan and the Pacific Ocean. Four fieldwork campaigns based on measurement of radioactive dose rates in fine riverine sediment that has recently deposited on channel bed-sand were conducted between November 2011 and May 2013 to document the spread of fallout by r...

The main objective of this study was to investigate ecologically healthy regions near a dam reservoir. This study developed a model for assessing habitat suitability as a proxy for the ecological value of reservoirs. Three main factors comprising nine assessment variables were selected and classified as having a habitat suitability (HS) between 0 and 1: (1) geomorphic factors of altitude, slope...

Excessive nutrient loadings from drainage areas and resulting water quality degradation in rivers are the major environmental issues around world. The further deteriorates for large seasonal variation of precipitation flow. Environmental decision makers have been exploring affordable effective ways securing flow (EF) to improve quality, especially dry seasons, agricultural reservoirs attracted ...
