Predicting 85th Percentile Speeds for Safer Roads: A Case Study Using Regression-Based Estimation

Operating speed is one of the key parameters in road design, classification, and safety assessment. This study examines changes in 85th percentile (operating) speeds (V85) across the analyzed road network in the Middle East, between 2016 and 2020, using a combined dataset of meas...

Long-term temperature, oxygen and water clarity trends in Swiss lakes

Abstract. Water temperature, electrical conductivity, dissolved oxygen concentration, and water clarity are key variables routinely measured in Swiss lakes by lake monitoring programs run by cantonal environmental offices and international lake commissions. In most lakes, data is...

High-performance computing in the hydrosciences

This paper provides an overview of High Performance Computing (HPC) in the hydrosciences. It begins with the development of HPC architectures and performance as well as with the expansion of application fields over the last decades. Subsequently, four HPC application cases are pr...
