Management Of An Urban Stormwater System Using Projected Future Scenarios Of Climate Models: A Watershed-Based Modeling Approach, Ranjeet Thakali, Ajay Kalra, Sajjad Ahmad, Kamal Qaiser
Management Of An Urban Stormwater System Using Projected Future Scenarios Of Climate Models: A Watershed-Based Modeling Approach, Ranjeet Thakali, Ajay Kalra, Sajjad Ahmad, Kamal Qaiser
Civil and Environmental Engineering and Construction Faculty Research
Anticipating a proper management needs for urban stormwater due to climate change is becoming a critical concern to water resources managers. In an effort to identify best management practices and understand the probable future climate scenarios, this study used high-resolution climate model data in conjunction with advanced statistical methods and computer simulation. Climate model data from the North American Regional Climate Change Assessment Program (NARCCAP) were used to calculate the design storm depths for the Gowan Watershed of Las Vegas Valley, Nevada. The Storm Water Management Model (SWMM), developed by the Environmental Protection Agency (EPA), was used for hydrological modeling. …
Integrating System Dynamics And Remote Sensing To Estimate Future Water Usage And Average Surface Runoff In Lagos, Nigeria, Gilles A. Kandissounon, Ajay Karla, Sajjad Ahmad
Integrating System Dynamics And Remote Sensing To Estimate Future Water Usage And Average Surface Runoff In Lagos, Nigeria, Gilles A. Kandissounon, Ajay Karla, Sajjad Ahmad
Civil and Environmental Engineering and Construction Faculty Research
The goal of this study was twofold; first analyze the patterns of water consumption in Lagos, Nigeria and use them in a System Dynamics (SD) model to make projections about future demand. The second part used remote sensing to quantify the contribution of extensive land use/cover change to urban flooding. Land use/cover dynamics over the past decade was analyzed using satellite imagery provided by Landsat Thematic Mapping (TM). Unsupervised classification was performed with false color composite using the Iterative Self-Organizing Data Analysis (ISODATA) technique in a Geographic Information Systems (GIS). The study area was divided into four different land use …
Changing Demands From Riparian Evapotranspiration And Free-Water Evaporation In The Lower Colorado River Basin Under Different Climate Scenarios, Daniel Bunk
UNLV Theses, Dissertations, Professional Papers, and Capstones
Observed and projected trends in riparian evapotranspiration (ET) and free-water evaporation are examined in this study to help improve water demand forecasting, particularly in modeling of lower Colorado River system reservoir operations. While most previous research in the Colorado River basin have focused on the impacts of climate change and climate variability on water supply, the impacts of changing climate on water demand have not been adequately addressed. Changes in temperature, precipitation, and wind patterns are expected to increase evaporative demands in the lower Colorado River mainstream, including free-water evaporation and ET from riparian vegetation, and may also impact infiltration …
Changing Climatic Conditions In The Colorado River Basin: Implications For Water Resources Management In The Las Vegas Valley, Srijana Dawadi
Changing Climatic Conditions In The Colorado River Basin: Implications For Water Resources Management In The Las Vegas Valley, Srijana Dawadi
UNLV Theses, Dissertations, Professional Papers, and Capstones
Climate change affects the water available in a region. It also affects the water demand, because of the increase in temperature. A system dynamics model was developed for the Colorado River Basin (CRB), operating at a monthly time scale, to assess the potential impacts of climate change on streamflow in the Colorado River and its subsequent impact on the water resources management in the Las Vegas Valley (LVV). The effect of climate change on streamflow was evaluated using 16 global climate model outputs for 3 emission scenarios, also referenced in the Inter-Governmental Panel on Climate Change Fourth Assessment Report.
