The catchment feature model addresses two questions in the field of multimodal interaction: how we bridge video and audio processing with the realities of human multimodal communication, and how information from the different modes may be fused. We argue from a detailed literature review that gestural research has clustered around manipulative and semaphoric use of the hands, motivate the catch...

Extensive flood damages all over the world necessitate its control and operation. Hydrologic impacts of land use change appear in many ways such as total runoff, and flood peak flow. This study was performed in 2014 and aimed to investigate the impacts of land use changes on the occurrence of floods in the catchment of Boostan dam in Golestan province, Iran. For this purpose, Watershed Modeling...

Over the course construction of Tugu Reservoir, it is proposed to build a spillway gate increase its performance as flood control infrastructure. The planning requires calculation design discharge for Reservoir Catchment Area. latest was carried out during in 2010. Therefore, necessary evaluate and recalculate using data. This study aims model Area HEC-HMS software. software able simulate rainf...

[1] Dozens of large, low‐gradient alluvial fans are present within impact crater basins on the cratered highlands of Mars. The timescales and climate conditions that were required to generate such fans are unknown, but testable through our understanding of terrestrial hill slope erosion in the presence of precipitation. Previous estimates of fan formation time vary from years to millions of yea...

Rainstorms can flush large amounts of faecal pollution from land sources into water bodies, threatening, particularly, contact recreation and bivalve shellfish harvest. We quantified the faecal pollution loads of stormflows in the Toenepi Stream, draining a catchment in intensive dairy-farming (Waikato Region, New Zealand). In this stream, as is typical, E. coli concentration peaks well ahead o...

Catchment area and watershed delineation is a common task in hydrology. The determination of the catchment is still as a challenge considered being crucial key issues particular in flat terrains. Three concepts could be briefly identified through: the manual delineation of a catchment based on a topographic map with contour lines which is a difficult task for flat terrains, by combination of fi...

Integrated catchment policies are widely used to manage natural resources in Australian catchments. Decision support tools available to aid integrated catchment management are often limited in their integration of environmental processes with socio-economic systems. Fully integrated models are required to support assessments of the environmental and economic trade-offs of catchment management c...

In this study, faecal sterols were used to identify human faecal pollution in a non-sewered catchment in Southeast Queensland, Australia. In all, 36 water samples were collected from six sites on six occasions and the concentration of sterols were determined using gas chromatography and mass spectrometry. The stanols concentration in water samples generally increased with increased catchment ru...

Many estuaries are becoming increasingly eutrophic from human activities within their catchments. Nutrient loads often are used to assess risk of eutrophication to estuaries, but such data are expensive and time consuming to obtain. We compared the percent of fertilized land within a catchment, dissolved inorganic nitrogen loads, catchment to estuary area ratio and flushing time as predictors o...

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...
