... HSY has rebuilt the Helsinki combined sewer model for better accuracy and usability over the last years. The area covered by the model and its size details are shown in Figure 2a. The model includes even small pipes, the relevant separate sanitary sewer network, each customer's inflow and the inflow patterns read from water supply system measurements, all pumping stations and overflow structures, the relevant external flows from the surrounding areas that are not part of the model itself, the sewage quality model, and hydrology. ...

Depuis les dernières années, de nombreuses données d’origine et de nature variées deviennent aisément accessibles. Certaines, liées aux attributs forestiers, permettent d’accroître la précision des inventaires forestiers et de produire des estimations à des échelles beaucoup plus fines qu’auparavant. Sur cette base, une approche d’inventaire « mult...

Some different methods exist to restrain railway induced ground vibrations. In this study deep stabilisation has been examined as a countermeasure against the vibrations. In Finland there exist dozens of areas where train-induced vibration causes disturbance in the ground surrounding the railway. Koria is one of the residential areas suffering most...
