(van der) Mention d'édition : Institute for Land and Water Management Research Editeur : Institute for Land and water Management Research Année de publication : 1977 ISBN/ISSN/EAN : CI-09394 Note générale : A description is given of an operational field registration unit for open and submerged drain outflow, groundwater depth and rainfall. The drain outflow meter has a measuring range from 20 to 400 cm3/s with a mean error in recorded sediment free outflow of 15 per cent at flow rates below 60cm3/s and 1.5 per cent at higher flow rates. Its weight is 6-8 kg, depending on drain outlet it is adopted to, has a length of 90cm and a height of 50cm. The groundwater level meter has a measuring range of 1.25cm but it can be adopted to deeper levels. Its accuracy is 0.5cm were a float of 4.5cm in a 5cm diameter piezometer tube is used.

H. A. M. ; Oosterom, H. P. Mention d'édition : ILWMR IVCW Editeur : ILWMR IVCW Année de publication : 1979 ISBN/ISSN/EAN : CI-08773 Note générale : Nitrogen and phosphate pollution of surface water by various potential sources is discussed in general attention is paid to the more or less natural sources: precipitation, leaching of natural soil constituents, seepage of saline groundwater and to the artificial sources: domestic waste water, inlet water from storage canals, leaching of fertilizers, surface runoff and discharge of dune water. For three polders and three book catchmont areas the total nitrogen and phosphate load has been calculated. Polders and catchmant areas differ with respect to the geo - hydrological situation, soil,type, agricultural soil use and population density. In the sandy soil of the brook cathment areas on the other hand, the nitrogen pollution originates for the largest part from scattered agricultural sources. The contribution to the phosphate laod by domestic sewage depends on the population density and the treatment method of waste water, out generally speaking it is an important factor.
