In this study, the free-surface dynamics in several turbulent flows commonly found in nature were investigated using a synchronised setup consisting of an ultrasonic sensor and a high-speed video camera. Basic sensor capabilities were examined in dry conditions to allow for a better characterisation of the present sensor model. The ultrasonic sensor was found to adequately reproduce free-surface dynamics up to the second order, especially in two-dimensional scenarios with the most energetic modes in the low frequency range. The sensor frequency response was satisfactory in the sub-20 Hz band, and its signal quality may be further improved by low-pass filtering prior to digitisation.

For this purpose, the deammonifying sludge available at the side stream was investigated for nitrogen (N) removal with respect to the operational factors temperature (15-30°C), pH value (6.0-8.0) and chemical oxygen demand (COD)/N ratio (≤1.5-6.0). The highest and lowest N-removal rates of 0.13 and 0.045 kg/(m³ d) are achieved at 30 and 15°C, respectively. Different conditions of pH and COD/N ratios in the SBRs of Partial nitritation/anammox (PN/A) significantly influenced both the metabolic processes and associated N-removal rates. The scientific insights gained from the current work signifies the possibility of mainstream PN/A at WWTPs.

This paper presents the first study on application of the optical flow method to aerated stepped spillway flows. For this purpose, the flow is captured with a high-speed camera and illuminated with a synchronized LED light source. The flow velocities, obtained using a basic Horn-Schunck method for estimation of the optical flow coupled with an image pyramid multi-resolution approach for image filtering, compare well with data from intrusive conductivity probe measurements. Application of the Horn-Schunck method yields densely populated flow field data sets with velocity information for every pixel. It is found that the image pyramid approach has the most significant effect on the accuracy compared to other image processing techniques. However, the final results show some dependency on the pixel intensity distribution, with better accuracy found for grey values between 100 and 150.}, language = {en} } @article{HoettgesRitterbachEls1987, author = {H{\"o}ttges, J{\"o}rg and Ritterbach, E. and Els, H.}, title = {Optical Improvement of LDV-Measurement in Pipe Flow / Ritterbach, E.; J.

Such waves can occur in lakes and fjords, or due to glacier calving in bays or at steep ocean coastlines. Infrastructure and residential houses along coastlines of those waterbodies are often situated on low elevation terrain, and are potentially at risk from inundation. Impulse waves, running up a uniform slope and generating an overland flow over an initially dry adjacent horizontal plane, represent a frequently found scenario, which needs to be better understood for disaster planning and mitigation. This study presents a novel set of large-scale flume test focusing on solitary waves propagating over a 1:14.5 slope and breaking onto a horizontal section. Examining the characteristics of overland flow, this study gives, for the first time, insight into the fundamental process of overland flow of a broken solitary wave: its shape and celerity, as well as its momentum when wave breaking has taken place beforehand.}, language = {en} } @article{BaierHebel2001, author = {Baier, Reinhold and Hebel, Christoph}, title = {Parkraumbewirtschaftung und Modal-Split - die relativierte Stellschraube}, series = {Strassenverkehrstechnik . 45 (2001), H. 4}, journal = {Strassenverkehrstechnik . 45 (2001), H. 4}, isbn = {0039-2219}, pages = {165 -- 167}, year = {2001}, language = {de} } @article{RegerDoeringKuhnhenne2016, author = {Reger, V. and D{\"o}ring, Bernd and Kuhnhenne, M.}, title = {Passive und aktive Maßnahmen zur Fl{\"a}chenk{\"u}hlung im Stahl(leicht)bau}, series = {Bauingenieur}, volume = {91}, journal = {Bauingenieur}, number = {Jul/Aug}, publisher = {VDI Fachmedien}, address = {D{\"u}sseldorf}, issn = {0005-6650}, doi = {10.37544/0005-6650-2016-07-08-63}, pages = {309 -- 316}, year = {2016}, abstract = {Mit steigenden D{\"a}mmstandards und h{\"o}heren Komfortanforderungen der Nutzer ger{\"a}t die Problematik der sommerlichen {\"U}berhitzung zunehmend in den Fokus.
