Landbouwkundig en natuurtechnisch beheer van rivierdijkgrasland

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...

Erosiebestendigheid van gras op klei taluds

A guide to the use of grass in hydraulic engineering practice

Guidance on the use of grass to stabilise surfaces subject to erosion by intermittent flow. Provides information on the erosion resistance and frictional resistance of grass. Includes recommendations on grass mixtures, etc. Extensive literature survey

Evaluation of potential use of vegetation for erosion abatement along the Great Lakes shoreline

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...

Stroombestendigheid van een grasmat op de dijk van Oostelijk Flevoland

Scour resistance of farm dam spillways with grass dormant

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...

Resistance of low cost surfaces for farm dam spillways

Third report on use of grass on farm spillways; tests on slopes 1:10 to 1:2.5 (prototype scale tests). Permissible velocities suitable for design were given.

Hydraulic characteristics of low cost surfaces for farm dam bywash spillways

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...

By-wash spillways for farm dams

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...

Low cost spillway surfaces for farm dams

With the aid of a grant from the Water Research Foundation of Australia, the Water Research Laboratory has undertaken an investigation into surface treatments for small farm dams Vegetal cover with natural gr asses and low cost soil and bitumen admixtures are under study. As a preliminary to laboratory and field testing, a survey of available...
