The paper attempts to establish the total quantity of surface tributary inflow to a coastal lake as illustrated with an example of the Lake Łebsko. The surface tributary inflows include not only tributary rivers in the catchment, but also forced
inflow from pumping stations on polders situated around the reservoir, periodical tributary inflow from the sea as well as tributary inflow from direct catchment. The main works were based on local investigations as well as a query of source materials
Spatial patterns of geomorphic processes in channelized tributary streams
The A. examines spatial patterns of widening and incision in 3 tributary streams of the Lower Hatchie River (west Tennessee) with similar land use history and geology, using w/d ratios calculated from field measurements of channel morphology
. The results suggest that channel incision dominates 2 of the tributaries, while widening dominates a third tributary. The dominance of channel widening or incision throughout a system results in large amounts of sediment being produced throughout the system
Which tributaries disrupt downstream fining along gravel-bed rivers?
In this paper a procedure for identifying significant lateral (tributary) sources, whithout the benefit of grain-size information, is outlined. A high-resolution characterisation of bed material texture along 2 Canadian gravel-bed rivers facilated
classification of all their perennial tributaries as either significant or insignificant. 3 absolute tributary basin parameters and their relative counterparts, chosen to reflect the likely controls on tributary significance, are then used to develop
a discriminant function which isolates a large proportion of significant tributaries while minimising incorrect classifications.
Influence of storm-related sediment storage on the sediment delivery from tributary catchments in the Upper Waipaoa River, New Zealand
Sediment delivery ratios focused on the influence of storm-related sediment storage are measured at Matakonekone and Oil Springs tributaries of the Waipaoa River basin, east coast of New Zealand. The terrace deposits of both tributaries show
a tributary to the main stream by the volume of sediment generated at erosion sites in the tributary catchment.
Adjustment of mainstream - Tributary relation upstream from a reservoir : an example from the Laohahe River, China
Based on data from the Laohahe River and the Yangchangzihe River, its tributary, both located above the Honshan Reservoir, effort has been made to reveal the response of tributary channel to the rising base-level induced by the reservoir
construction and the sedimentation in the river mainstream. This paper also discusses the feedback from the tributary to the channel adjustment of the river mainstream. Due to the strong sedimentation in the river mainstream, the response of channel adjustment
of the tributary was quite complex, and this has been generalized as a 5-stage descriptive model in this study.
Changes in stream channel characteristics at tributary junctions
. This study has shown that expected relationships exist only at relatively symmetrical junctions (Q2/Q1 > 0.7), where the simultaneous hydrological responses of the tributaries predominantly control channel morphology and sediment properties.
Dominierende und tributäre Bestandteile des fluvialen Abtragungsreliefs. (Principal and tributary components in fluvial degradation relief)
The formerly proposed concepts of slope of degradation and of initial and dominating lines of erosion as also the processes which account for those phenomena are explicated. Normal and subnormal water-divides and various types of a tributary
condition of area within the mechanisms of degradation are discussed. An exact subdivision of fluvial degradation reliefs into components of dominating and of tributary landforms or into corresponding processes of degradation is rendered possible
The occurrence of obtuse junction angles and changes in channel width below tributaries along the Mekong River, south-east Asia
SPOT-5 imagery from Google Earth was used to identify and catalogue junction geometries and downstream changes in channel width below tributary junctions along a 2200 km reach of the Mekong River. Of the 284 junctions identified, 30% were found
to be obtuse. Meander extension of the incoming tributary and deflection of the tributary across bedrock shoulders were found to be the dominant geomorphological causes of the obtuse tributary junctions. The relationship between the width of the tributary
channels and the width of the mainstem upstream and downstream of the confluences was analysed. It was observed that, over the whole reach, a slight narrowing occurred immediately below tributary junctions. The geological control observed suggests
Generic styles of mainstream response to lateral inputs are investigated using a one-dimensional sediment routing model with multiple grain size fractions. Numerical experiments isolate the effects of 3 parameters : ratio of tributary to mainstream
water flux, ratio of tributary to mainstream bedload flux, and ratio of tributary to mainstream bedload diameter. The primary distinction is between junctions that aggrade, causing local profile convexity with interrupted downstream fining, and junctions
Effect of baselevel change on floodplain and fan sediment storage and ephemeral tributary channel morphology, Navarro River, California
This study reports data for 3 ephemeral tributary systems in the Navarro basin; however, field reconnaissance suggests that maintenance of numerous small tributary crossings induces similar responses elsewhere on the North Fork and Navarro River
Tributary-trunk stream relations in a cut-and-fill landscape : a case study from Wolumla catchment, new South Wales, Australia
In this paper, the timing of incision and the relation between trunk stream and tributary streams are explained for Wolumla catchment on the south coast of New South Wales. To date, the linkage of tributary and trunk streams has been neglected
This paper examines sediment transfer processes at river junctions, using as a case study the River Kas, a tributary of the River Mula, Godavari basin, Maharashtra. The study uses 4 cross-sections, 2 from upstream tributaries, one in the main
confluence zone, and one downstream. Sediment samples are collected from each cross-section and adjacent banks. To understand the tributary impact on the main channel, variations in sand, silt and clay percentages and variations in the shape of sediment
particles were recorded. Sediment characteristics between tributary and the main stream reflect both downstream distance from sediment source and the characteristics of the respective transport processes. The distribution of fine material at the tributary
mouth suggests that there have been instances in the past where the mainstream flow has dominated the confluence and has led to slack water deposits on the tributary mouth. In this large seasonal river, confluence sedimentology is a joint product of flow
In this paper the writer tries to analyze urban tributary areas and daily city regions of central cities according to the analysis of connectivity between central cities and their surrounding municipalities by using commuting data among
municipalities (1985 Census). Instead of the concept of a city region the writer uses the concepts of a daily city region corresponding to the commuting areas of a central city and an urban tributary area consisting of a wider area. As shown in another paper
tributary areas and then observed the characteristics of each WAMS.
The behavior of specific sediment yield in different grain size fractions in the tributaries of the middle Yellow River as influenced by eolian and fluvial processes
Based on data from 35 stations on the tributaries of the Yellow River, annual specific sediment yield in 8 grain size fractions has been related to basin-averaged annual sand-dust storm days and annual precipitation to reveal the influence of eolian
The origin and development of the Nyl River floodplain wetland, Limpopo Province, South Africa: trunk-tributary river interactions in a dryland setting
of accommodation space for sedimentation has previously been attributed to tectonic controls, but new investigations reveal that a more likely cause is progradation of coarse-grained tributary fans across the narrow river valley downstream of the main area
Late Quaternary alluvial stratigraphy of a low-order tributary in central Texas, USA and its response to climate and sediment supply
This paper presents the late Quaternary alluvial stratigraphic study of a low-order tributary in central Texas, using Cowhouse Creek as a case study. The AA. correlate episodes of stream incision and alluviation to climate records and to previous
Some new concepts are developed and terms are introduced concerning channel processes manifestation under conditions of confluent rivers interaction (within the area of river junction, in the lower reach of the tributary, in the zone
of the tributary influence on the trunk stream etc.). Delta formation in the junctions appeared to be controlled by solid runoff and backwater phenomena. Specific conditions are required to form fill-in delta, prograding delta or other morphological types of river
