Laser Profiler (LP) data from aerial laser surveys have been increasingly used as topographical inputs to numerical simulations of flooding and inundation in river basins. LP data has great potential for reproducing topography, but its effective usage has not yet been fully established. In this study, flooding and inundation are simulated numerically using LP data for the Jobaru River basin of ...

A curve-theorem based approach is proposed and is used to handle NDVI data. The curve-theorem based approach includes a general index CD and two nonlinear transformations SAV and CAV . It is applied to Landsat MSS images of the Yellow River Delta, taken on 1 December, 1976 and 3 December, 1988. Results show that CD can describe the general situation of vegetation cover change in the Yellow Rive...

A study of the spatial and temporal changes in land use and land cover (LULC) was conducted using Remote Sensing and GIS. We analyzed the LULC of Bharathapuzha river basin, south India using multispectral LANDSAT imageries of 1973-2005 time periods. 31% depletion in the natural vegetation cover and 8.7% depletion in wetland agriculture area were seen in the basin during the period. On the other...

The context of urban rivers is one pollution their courses, the degradation riparian habitats, loss biodiversity, and marginalization human populations that live next to them. Due growth, hydrological dynamics in entire basins hydromorphology are changing. This situation increases flooding, decreases availability water for use, disconnects from city. Agroforestry integration cultural, wild, dom...

As an emerging contaminant, rare earth elements (REEs) are becoming environmental concern, especially in Chinese cities. This study investigated the distribution of REEs river water and tap samples Guiyang, Southwest China. In all samples, concentrations total dissolved REE (∑REE) ranged from 15.1 to 53.3 ng·L–1, with heavy enriched than light elements. Most showed significant positive Gd anoma...

Culture sustainability is one of the indispensable components of sustainability. Culture has likely always been an important element for promoting urban and rural sustainable development. It is now playing an increasingly significant role in sparking and incubating innovation, which is becoming the main driver of economic growth and competitiveness. Unfortunately, little research has been condu...

To provide information on the ecology of Pseudomonas aeruginosa in nature, bacteriological surveillance was performed in the defined area in Hokkaido, Japan. P. aeruginosa was isolated from water samples of Ushubetsu River in the down stream from the urban area of Asahikawa. P. aeruginosa was isolated from fecal samples of pigs but not from samples of soil of a tomato field, sand of sandboxes i...

This paper is concerned with the integrated modelling, and control of urban wastewater systems (UWS) comprising the wastewater treatment plants (WTP), receiving waters (river) and the sewer networks. A unified framework is developed and simple models are used and implemented in Matlab/Simulink to produce a toolbox. Novel linear and nonlinear control structures are then proposed to design integr...

Dissolved oxygen (DO) is not only a fundamental parameter of coastal water quality, but also an indication of organics decomposed in water and their degree of eutrophication. There has been a concern about the deterioration of dissolved oxygen conditions in the Minjiang River Estuary, the longest river in Fujian Province, Southeast China. In this study, the syntheses effects on DO was analyzed ...
