Hysteresis and scale in catchment storage, flow and transport
The closure problem of representing hydrological boundary fluxes given the state of the system has been described as the scientific ‘Holy Grail’ of hydrology. This relationship between storage state and flux should be hysteretic and scale dependent because of the differences between velocities and celerities in a hydrological system—effectively velocities are storage controlled, and celerities ...
متن کاملWater Quality from a Mixed Land-Use Catchment in Miri, Sarawak
Urbanization has been found to impact stormwater runoff quantity and quality. A study catchment with mixed land use, residential and industrial were investigated and the water quality discharged from the catchment were sampled and tested for four basic water quality parameters; BOD5, NH3-N, NO3-N and P. One dry weather flow and several stormwater runoff were sampled. Results were compared to th...
متن کاملModelling of Land-use Changes in a West African Catchment
Land-cover and land-use changes are an important part of global change but determine as well livelihoods at local and regional level. The knowledge of change trajectories and possible future conditions is important for a sustainable development strategy. Further on, reliable scenarios with spatial explicit simulations are needed as planning tools for decision makers. This paper describes an exa...
متن کاملCatchment land use predicts benthic vegetation in small estuaries
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...
متن کاملInvestigation of land use changes in Gorganrood catchment using Google Earth Engine platform
The purpose of this study is to investigate landuse changes in Gorganrood basin in 2001, 2010 and 2019. Using Landsat and Product-Modes satellite images, used maps were prepared using the classification method of random forest algorithm in Google Earth Engine. Satellite imagery was classified into eight classes including forest, cropland, shrubland, grassland, wetland, urban, barren, and water....
