Abstract. Human immediate response is contextualized into different time compartments reflecting the tsunami early warning chain. Based on available and evacuation quantified. The latter incorporates accessibility of safe areas determined by a hazard assessment, as well environmental demographic impacts speed properties assessed using Cost Distance Weighting GIS approach. Approximately 4.35 million Indonesians live in endangered southern coasts Sumatra, Java Bali have between 20 150 min to...
Abstract. An innovative newly developed modular and standards based Decision Support System (DSS) is presented which forms part of the German Indonesian Tsunami Early Warning (GITEWS). The GITEWS project stems from effort to implement an effective efficient Mitigation for coast Indonesia facing Sunda Arc along islands Sumatra, Java Bali. geological setting active continental margin very close densely populated areas a particularly difficult one cope with, because potential tsunamis' travel...
The population balance equation finds many applications in modelling poly-dispersed systems arising engineering such as aerosols dynamics, crystallization, precipitation, granulation, liquid-liquid, gas-liquid, combustion processes and microbial systems. lays down a modern approach for the complex discrete behaviour of Due to industrial importance liquid-liquid extraction columns separation chemicals that are not amenable by distillation, Windows based program called LLECMOD is developed....
Water quality in estuarine and coastal waters of Aotearoa New Zealand is concern yet currently under-monitored, reflecting challenges sampling at regular intervals across large areas. Satellite products are underutilised (globally) by management agencies but could be part a holistic approach. NIWA-SCENZ (Seas, Coasts Estuaries Zealand) website providing access to MODIS-Aqua moderate spatial resolution (500 m) relatively clear (Case 1) turbid 2). It also provides advanced analytical tools on...
The shallow marine environment represents a region of high biological productivity, ecological diversity, and complex oceanographic conditions, often supports various human activities industries. Mapping the seafloor in environments reveals features detail, shedding light on range natural anthropogenic processes. We present high-resolution (2-m) multibeam dataset, combined with geologic samples that complete map from land-water interface to ~350 m water depth within Queen Charlotte...
Abstract Die Dimensionierung von Extraktionskolonnen erfolgt in der Regel auf Basis experimentellen Untersuchungen im Labor und Auslegungsversuchen Technikum. Eine neue, alternative Auslegungsmethode basiert Einzeltropfenuntersuchungen zum Stoffaustausch zur Sedimentation Labormaßstab, aus denen die erforderlichen Modellparameter Simulation Technikumskolonnen ermittelt werden. Diese bisher bei Standardtestsystemen erfolgreich erprobte Vorgehensweise soll Industrie etabliert Hierzu werden...
A rigours mathematical model based on the bivariate population balance frame work (the base of LLECMOD “Liquid-Liquid Extraction Column Module”) for steady state and dynamic simulation pulsed liquid-liquid extraction columns is developed. The simulates coupled hydrodynamic mass transfer (packed sieve plate) columns. It implemented using visual digital FORTRAN then integrated into program. Experimental validated correlations are used estimation droplet terminal velocity in single swarm...
Abstract The new scale‐up concept for extraction columns relies on three identities being kept idem, as is the total specific flow rate, energy dissipation, and mean droplet residence time in a compartment. population balance‐based model allows maintaining hydrodynamic similarity different geometries, mini‐ or pilot plant. This leads to similar breakage coalescence probabilities giving comparable size distributions, thus mass transfer area efficiency. A frequency term has been developed...
Abstract Effectively forecasting and communicating flood hazards at national or continental scales is critical to reducing impacts of flooding. Yet, it remains a challenge due the predominance ungauged catchments in often complex steep terrain. We present development, communication, evaluation awareness system, Aotearoa (New Zealand) Flood Awareness System, AFAS. Forecasts are produced with an uncalibrated, semi‐distributed hydrological model, driven by high‐resolution convective‐scale...
Auf Basis von Einzeltropfen- und Tropfenschwarmuntersuchungen in charakteristischen Kolonnensegmenten wurden die Parameter zur Kolonnensimulation gerührter Kolonnen unter Stoffaustausch für das bivariante Tropfenpopulationsbilanzmodell bestimmt. Die beschreiben den Tropfentransport Einfluss des Energieeintrages der Kolonnengeometrie sowie Einzeltropfenzerfall Berücksichtigung zeitlich veränderlichen Stoffeigenschaften. Trotz Größenunterschiede lässt sich zeigen, dass aus...
Floods cause over $40 Billion of damage worldwide every year. In Aotearoa New Zealand, it is the most frequent natural disaster, with an average annual cost NZ$100 million for residential properties. Effectively forecasting and communicating flood hazards at national or continental scales critical to reducing impacts flooding. However, developing national-scale river flow systems remains a challenge due predominance ungauged catchments in often complex steep terrain. We will present model...
