Old dikes are usually still constructed entirely from clay and since 1953 many much heavier dikes have been made from a core of sand with a covering. This construction puts heavier requirements on the covering, as it also does for grassland on a clay layer. These and other developments have led to the need for more insight into the strength of...

Bij zeer veel zeedijken in Sleeswijk-Holstein en op Jutland breken de golven tijdens de maatgevende stormvloeden op grasmatten. Deze groene zeedijken blijken voldoende veilig te zijn. De aanleg wordt gekarakteriseerd door o.a. flauwe buitentaluds en een gedeeltelijke bezoding met zoute kwelderzoden. Bij een voldoende brede kwelder is een harde...

Minderhoud, J.W. (author)
Aan de orde komen waar een natuurtechnisch beheer gewenst is, waar met een landbouwkundig beheer kan worden volstaan, welke mogelijkheden deze gebruikswijzen hebben, welke moeilijkheden zich kunnen voordoen en wat men bij een goed gebruik dient te doen of dient na te laten. De adviezen voor het graslandbeheer hebben steeds als uitgangspunt dat...

Erosional problems and damages include loss of land, imperilment to roadways, loss of recreational beach, loss of access to the lakes and structural damage to dwellings, boathouses, docks, and stairways: Some shoreline conditions along the Great Lakes are difficult to alter to control erosion, particularly in areas where there is no beach or...

Yong, K.C. (author)
This report is the fourth in a series dealing with the use of natural grasses and bituminous and soil admixtures for surfacing farm dam bywash spillways. When the work reported here was completed, the test channels were demolished to make way for new construction, and no further tests of this nature are contemplated. The previous report (Yong...

As part of a program of research aimed at improving the design and construction of farm dams, the Water Research Laboratory, has with the aid of a grant from the Water Research Foundation of Australia, undertaken a study of the protection afforded to spillways by various low cost surfacing techniques. These include vegetal cover by natural...

Model studies formed a basis for investigating the hydraulics of bywash spillways for farm darns When constructed in natural earth such spillways are trapezoidal in cross section The surface of the spillway needs protection from scour and this protection is usually in the form of grass. These tests extended to variations in spillway geometry and...
