Currently a new wave flume for hydraulic experiments near to prototype scale is under construction at Deltares. In the flume, modern measurement equipment will be installed. One of the potential sensor techniques is Terrestrial Laser Scanner (TLS) based range measurements of water waves. TLS range measurements are a very fast and accurate method for solid surfaces, providing temporal and spatia...

In a set of streamside mesocosms, stream ecosystem respiration (ER) increased with biofilm biomass and flow heterogeneity (turbulence) generated by impermeable bed forms, even though those bed forms had no hyporheic exchange. Two streamside flumes with gravel beds (single layer of gravel) were operated in parallel. The first flume had no bed forms, and the second flume had 10 cmhigh dune-shaped...

The classic notion of a win–win situation has key flaw in that it cannot always offer the parties equal amounts winningsbecause each party believes they are winners. In reality, one may win more than other. This strategy is not limited to single product or negotiation; be applied variety situations life. We present novel way measure this paper. proposed method employs fuzzy logic create mathema...

Flume studies have been carried out to investigate flow structure for relatively low velocities and inundation for vegetation typical to floodplains and wetlands, such as grasses and bushes. Mean velocity profiles and turbulence characteristics from flume experiments on three different natural vegetal roughness types are reported. Two relatively new approaches for describing vertical velocity p...

We study provably effective and efficient data reduction for a class of NP-hard graph modification problems based on vertex degree properties. We show fixed-parameter tractability for NP-hard graph completion (that is, edge addition) cases while we show that there is no hope to achieve analogous results for the corresponding vertex or edge deletion versions. Our algorithms are based on transfor...
