Sustainable integrated catchment management is a complex task that often involves finding compromise between the views of multiple stakeholders that may not easily be brought to consensus. Interactive three dimensional (3D) visualisations of landscapes can facilitate discussion, but these can only partially inform decision makers as many important aspects of interventions are abstract. Such abs...

There is an increasing awareness that rivers need more room in order to safeguard flood safety under climate change conditions. Contemporary river management is creating room in the floodplains and allowing, within certain bounds, natural processes of sedimentation and erosion. One of the aims is to restore dynamic conditions, so as to get a sustainable and more diverse river ecosystem that can...

Remote Sensing techniques with GIS were used to study the two sub-catchments of the upper catchment of Sukri River, Luni River basin. The measurement and analysis for the two sub-catchments were carried by using GIS for linear, areal and relief aspects. Both sub-catchments have low permeability, high surface run-off, and control of geologic structure. The morphometic analysis and measurements a...

This paper presents a multi-criteria based tool for assessing the relative impact of diffuse-source pollution to the Great Barrier Reef (GBR) from the river basins draining into the GBR lagoon. The assessment integrates biophysical and ecological data of water quality and pollutant concentrations with socio-economic information pertaining to non-point source pollution and (potential) pollutant ...

The opinions and interpretations expressed within are those of the authors and do not necessarily reflect the views of the Mekong River Commission. 4 FOREWORD The Lower Mekong Basin, covering major areas of Cambodia, Laos, Thailand and Vietnam, is a region of dynamic change and growth. Reports in the Mekong Development Series closely examine aspects of change and development in the river basin ...

The relationship between some habitat factors and fish assemblage was analyzed in the Taleghan River, Alborz Province, Iran. Fish specimens from thirty-three sites were sampled by electrofishing device in October 2014. The habitat parameters, including elevation (m), water depth (cm), river width (m), river slope (%), current velocity (m.s-1), number of large stone (> 15 cm), average stone diam...

The concept of an integrated multifunctional river management is gaining importance. For major rivers, restoring the contact between rivers and alluvial plains is an important goal, as riparian areas have a specific role for several riverine processes. However, former and current human activities are an obstruction or a limitation for river restoration. We studied the influence of former dredgi...

Historically, rivers have served as sources of drinking water, fisheries resources, transportation routes, irrigation supplies, and waste removal systems. Human civilization has had many major effects on rivers, dating back more than 5000 years when Egyptians built dams on the Nile to supply water for crops and human consumption. Today, management of large rivers requires a balance between huma...

Discharges of Combined Sewer Overflows (CSOs) into periurban rivers present risks for the concerned aquatic ecosystems. In this work, a specific ecotoxicological risk assessment methodology has been developed as management tool to municipalities equipped with CSOs. This methodology comprises a detailed description of the spatio-temporal system involved, the choice of ecological targets to be pr...

Storm water overflow from the combined sewer system might result in a sudden devastating impact to the local ecosystem in an urban river environment. In order to assess overflow pollution load during tropical rainfall, a web-based share vision modelling system is organized and designed in this study to investigate the resultant water quality impacts from both spatial and temporal aspects simult...
