Transport of estuarine sediment have a highly complex method, which is the combined effects result periodically reciprocating flow, ocean waves, and electrochemical characteristic sea water [1]. Settling velocity (SV) such parameter fundamental for researchers so that its accurate resolution has been regarded as top priority in correcting modelling numerical conceptual understanding fine dynami...

Cyanobacteria constitute the main toxin producers in inland water ecosystems and have extensive global distribution. The presence of hepatotoxins in aquatic environments is hazardous to human and animal health; even though the presence and identification of hepatotoxic microcystins in rivers and reservoirs of the world have been confirmed by several studies in the last few years. Herein, we stu...

Formation water is a by-product of oil and gas processing. This formation very different from fresh because contains harmful chemicals other elements contained in or gas. To prevent contaminating the environment, it necessary to reduce content using an adsorbent. Some parameters that indicate reduced mineral chemical must be considered for this research are pH, TDS (total dissolved solid), SG (...

In this study, the particle size distribution (PSD) of soil sediment from topsoil obtained erosion experiments under different conditions was measured. Rainfall simulators were used for rain generation on plots with slopes 22°, 30°, 34° and length 4.25 m. The influence external factors (slope initial state) aggregate evaluated by laser diffractometer (LD). representation percentage in eroded al...
