Geomorphic and vegetative recovery processes along modified stream channels of West Tennessee

Hundreds of miles of streams in West Tennessee have been channelized or otherwise modified since the tum of century. After all or parts of a stream are straightened, dredged, or cleared, systematic hydrologic, geomorphic, and ecologic processes collectively begin to reduce energy conditions towards the premodified state. One hundred and .five...

Sediment transport in rivers - report on experimental and theoretical investigations

I: Flow of water in a curved open channel with a fixed plane bed II: Flow of water in a curved open channel with a fixed uneven bed III: Accuracy of measurements in a curved open channel In this report the flow of water in a curved open channel, which consists of a38 m long straight section followed by a 90° bend with a radius of 50 m (see...

Influence of a sloping bed on the sediment transport direction

From Struiksma et al (1985) it can be concluded that more experimental evidence is needed to achieve a correct formulation. Generally the available data can only be used for an integral check as, for instance, was done by Zimmerman and Kennedy· ( 1978). More useful information could be obtained by carrying out experiments directed at the...

Algemene adviezen Maas, deel II: Morfologische gevolgen mogelijke ontgrinding benedenstrooms van Maaseik

Luanika waterway

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...

A morphological time-scale for rivers

Processes on degradation and aggradation of rivers have a speed depending on the characteristics of the rivers. Starting from the basic equations a morphological timescale, characterising these processes, is defined. This morphological time-scale is estimated for various rivers.

Ventidue anni di studi e lavori sul Po dal 1919 al 1941

Overview of the studies and works in the Po river (Italy) in the years 1919 to 1941. The object of the work is the arrangement of the river Po with "free flowing water"system for the navigation profit and for the hydraulic protection, projectation and execution of the works. Moreover there is described an economic an special system adopted for...
