Verhagen, H.J. (author)During the dry season shipping between Mongu and Kalabo is impossible, therefore this project was started to improve the situation by dredging. Dredging was started at Mongu harbour, where a new dredger was delivered, assembled and launched. Due to the urgency of the project dredging had to be started before a profound survey concerning the...report 1978

Verhagen, H.J. (author)In a densely populated country such as The Netherlands it is almost impossible to install large numbers of large windturbines on the mainland. That was the main reason to investigate the possibilities of siting the windturbines offshore on the Dutch part of the North Sea Continental Shelf, with a further advantage of a higher windfactor. The...report 1980

Verhagen, H.J. (author), Loman, G.J.A. (author)Norman Hells is situated on the north bank of the Mackenzie River, 145 km south of the Arctic Circle. The use of a pool-wide water flood system for secondary recovery and the features of the oil-bearing structure require six man-made platforms to provide vertical access to the portion of the oil pool that 1 ies beneath the Mackenzie River (60%)....report 1980

Verhagen, H.J. (author), Starink, A.C. (author)The calculations of bottom changes presented in our report "Terminal do Seixal Hydro-morphological study", February 1982 were based on a calibrated sediment transport formula. This formula was calibrated with the results of measurements made by Hydronamic in September 1981. These measurements were executed during one of the driest summers...report 1982
