1. A reach-scale remote sensing technique to relate wetland inundation to river flow

Author:
Frazier, Paul; Page, Ken
Source:
River research and applications 2009 v.25 no.7 pp. 836-849
ISSN:
1535-1459
Subject:
Landsat; floods; geomorphology; models; remote sensing; rivers; Australia
Abstract:
... Knowledge of the relationship between river flow and wetland inundation at a reach-scale is important for effective flow management, particularly, for environmental outcomes. Historical remotely sensed data, such as Landsat TM, provide the potential to determine the relationship between flow and wetland inundation for extended river reaches. In this paper we apply, adapt and evaluate a technique u ...

2. Functional trait differences between extant exotic, native and extinct native plants in the Hunter River, NSW: a potential tool in riparian rehabilitation

Author:

Subject:
analysis of variance; biodiversity; ecosystem services; ecosystems; flora; humans; indigenous species; introduced species; leaf area; leaves; phanerophytes; principal component analysis; rivers; shrubs; trees; New South Wales
Abstract:
... Riparian and riverine systems around the world are subject to human mediated degradation. It is increasingly recognized that rehabilitation of these systems is important to retain biodiversity and important ecosystem services. Plant functional traits represent a potentially useful but underutilized tool in the restoration or rehabilitation of ecosystems such as riparian systems. This study uses a ...

3. Growth of Phragmites japonica on a sandbar of regulated river: morphological adaptation of the plant to low water and nutrient availability in the substrate

Author:

River research and applications 2009 v.25 no.7 pp. 874-891
ISSN:

Subject:
Phragmites; belowground biomass; habitat destruction; nitrogen; nitrogen content; nutrient availability; nutrients; phenotypic plasticity; phosphorus; plant adaptation; plant growth; plant tissues; rhizosphere; riparian areas; rivers; sand; soil; soil sampling; stream channels
Abstract:
... The construction of upstream dams regulates flood magnitudes, reduces the inundation frequency of the riparian zones and curtails the discharge of sediments to the downstream. Adaptation of a Phragmites japonica colony growing at a rarely flooded sandbar (1.4 x 0.25 km) was investigated. Above- and belowground biomass was sampled, together with litters on the ground surface of a quadrat and soil i ...

4. Longitudinal patterns in flathead catfish relative abundance and length at age within a large river: effects of an urban gradient

Subject:
Pylodictis olivaris; adults; animal growth; body length; catfish; islands; land use change; longitudinal studies; population dynamics; population size; rivers; spatial variation; summer; urbanization; Kansas
Abstract:
... We investigated the spatial variation of flathead catfish (Pylodictis olivaris) relative abundance and growth in the 274 km long Kansas River to determine if population dynamics of catfish are related to urbanization. Electrofishing was conducted at 462 random sites throughout the river in summer, 2005-2006 to collect fish. Relative abundance of age 1 fish ([less-than or equal to]200 mm), subadult ...

5. Mapping river floodplain ecotopes by segmentation of spectral (CASI) and structural (LiDAR) remote sensing data

Subject:
aerial photography; automation; color; floodplains; land cover; lidar; remote sensing; rivers; texture; vegetation
Abstract:
... Floodplain land cover maps are important tools for river management and ecological assessment. These maps have to be revised regularly due to the dynamic nature of floodplains. Automation of the mapping process cuts the map processing time and can increase overall accuracy. Manual delineation and classification of vegetation is based on colour, contrasts (texture) and often-stereoscopic view of ae ...

Subject:
Brachionus; adverse effects; biomass; chlorophyll; correlation; dissolved inorganic nitrogen; grazing; hydrology; models; phosphorus; rivers; water temperature; zooplankton; Italy
Abstract:
... Water and quantitative zooplankton samples were collected at approximately monthly intervals from June 2000 to June 2002 in the middle section of the Po River (Northern Italy). Highly variable hydrological conditions were observed in the 2 years, with river flow varying approximately between 400 and 9300 m³ s⁻¹. Dissolved inorganic nitrogen (DIN) usually decreased at higher river discharges. Autot ...

7. Simulating the hydrology and total dissolved solids (TDS) of an ephemeral river in South Africa for environmental water requirement determinations

Author:
Hughes, D.A.

ISSN:

Subject:
hydrologic models; rivers; stream flow; total dissolved solids; water quality; water quantity; watersheds; South Africa
Abstract:
... Existing hydrological approaches to support the determination of environmental water requirements (EWRs) were largely developed for perennial rivers and may not be applicable to ephemeral rivers, where the quantity and quality dynamics of pool storage and frequency of connection can be more important than flow rates. The current understanding of semi-arid hydrological processes and how best to app ...

Abstract:
... The installation of 517 river works in the upper Hunter catchment, New South Wales over the last 50 years is linked to geomorphic river adjustment and flood history at catchment and reach scales. Nineteen types of works are classified into three categories consisting of engineering, heavy machinery and vegetation works. Since 1952, a transition in techniques has been detected from engineering-base ...
