Side channel spillways have a common usage in conveyance and distribution networks, high dams, water and wastewater treatment plants, and surface drainage networks. A side channel carries spatially varied flow with increasing discharge and their water surface profiles is a main feature in the design process. Usually, the bottom width of the channel is flared in the flow direction and an end sil...

Regional data needed for effective stream restoration include hydraulic geometry relationships (i.e., regional curves) and reference channel morphology parameters. Increasingly ecological conditions are being considered when designing, implementing, and assessing restoration efforts. We provide morphology relationships and associated ecological endpoint curves for reference streams in the Alaba...

Interrelations bctwecn drainage area, lake area, length, mean breadth, mean depth, and maximum depth arc examined in 2G2 rock basins and 137 basins lying in or dammed by glacial drift. The effect of lake dimensions upon the time taken for complete water replacement is calculated, and an illustration is given of the influence of lake urea and mean depth upon the tcmpcrature of surface and bottom...

In an industrial joining process, exemplified by deep penetration laser beam welding, ensuring a high quality of welds requires great effort. The cannot be fully established testing, but can only produced. fundamental requirements for weld seam in welding are therefore already laid the which makes use control systems essential automated production. With aid process monitoring that supply data i...

The drainage networks of catchment areas burned by wildfire were analysed at several scales. The smallest scale (1–1000 m) representative of hillslopes, and the small scale (1000 m to 1 km), representative of small catchments, were characterized by the analysis of field measurements. The large scale (1–1000 km), representative of perennial stream networks, was derived from a 30-m digital elevat...

global warming, as a consequence of greenhouse gases accumulation, has exerted significant impacts on biosphere. methane, a product of reduction processes of organic carbon in anaerobic conditions, is mainly emitted from paddy fields. the aim followed in this research is to evaluate the impact of midseason drainage on methane emission from paddy fields. the research was conducted with three tre...

The rational method is derived as a special case of kinematic wave flow. The definition of runoff coefficient is expanded from the flow-based ratio into volume-based ratio between the volumes under runoff hydrograph and rainfall hyetograph. The new method presented in this paper provides a dimensionless approach to theoretically derive the runoff coefficients for both the conventional two-flow ...
