Changes in climate, waterlogging hazards and regional floods are more prominent present context. The paper reviews potential of flood hazard dense urban areas, using GIS-based 1-D hydrodynamic model (MIKE URBAN). major factor contributing to the recent decades is climatic variability thus long-term variations precipitation drainage system an area were evaluated. MIKE URBAN (1-D) can be used com...

Agent based modelling (ABM) environments are becoming increasingly popular for investigating the effects of land use change. The ABM environment enables models to be developed that simulate biophysical, economic and social processes at different spatial and temporal scales. The smallest spatial area modelled here is the paddock at a daily temporal resolution, therefore enabling daily interactio...

Coal mining is one of the core industries that contribute to the economic development of a country but deteriorate the environment. Being the primary source of energy, coal has become essential to meet the energy demand of a country. It is excavated by both opencast and underground mining methods and affects the environment, especially hydrological cycle, by discharging huge amounts of mine wat...

This paper describes an integration of recent new developments in snow, runoff and vegetation growth into the National Center for Atmospheric Research Land Surface Model (NCAR LSM). The new model, referred to as the Versatile Integrator of Surface and Atmosphere processes (VISA), has been validated with observed data. The results have demonstrated that the NCAR LSM, after integrating with these...

Changes of land use/land cover have a significant impact on runoff by altering the surface evaporation, soil moisture conditions and the amount of trapped ground cover, which directly impact the sustainable development of the watershed ecology. In this paper, based on remote sensing images, we simulate runoff of land-use changes of different slopes using GIS technology and SWAT model in Erhai w...

Identifying phosphorus (P) source areas and transport pathways is a key step in decreasing P loading to natural water systems. This study compared the effects of two modeled runoff generation processes – saturation excess and infiltration excess – on total phosphorus (TP) and soluble reactive phosphorus (SRP) concentrations in 10 catchment streams of a Catskill mountain watershed in southeaster...

abstarct development of greenhouse gases in future periods not only causes change in average amounts of climate variables but also makes variables of this variability affected. then for sure concerning alternations followed with climate variables’ fluctuations and its average amounts in effecting on runoff would make more reliable results. in this inquiry initially fluctuations and average amou...

Radar measurement characteristics have important consequences on the predictability of flood hazards in urban watersheds. Site-specific hydrologic prediction is made possible by highresolution geospatial data and physics-based distributed modeling. Within the urban context, basin response is typically less than one-hour and basin sizes less than several hundred square kilometers. Forecast locat...
