The Lower Mekong Basin (LMB) is biologically diverse, economically important, and home to over 60 million people. region has undergone extensive environmental changes due multiple factors, including agricultural expansion intensification, deforestation, more river damming, increased urbanization, growing human populations, of industrial forest plantations, plus frequent natural disasters from flooding drought. also heavily used for transportation, fishing, drinking water, irrigation. To aid...
Multiple satellite-based earth observations and traditional station data along with the Soil & Water Assessment Tool (SWAT) hydrologic model were employed to enhance Lower Mekong River Basin region’s hydrological decision support system. A nearest neighbor approximation methodology was introduced fill Integrated Multi-satellite Retrieval for Global Precipitation Measurement mission (IMERG) grid points from 2001 2014, together Tropical Rainfall Mission (TRMM) continuous precipitation...
Managing transboundary river basins requires balancing tradeoffs of sustainable water use and coping with climate uncertainty. We demonstrate an integrated approach to exploring these issues through the lens a social-ecological system, combining remote in-situ earth observations, hydrologic models, social surveys. Specifically, we examine how change dam development could impact Se Kong, San Sre Pok rivers in Mekong region. find that will lead increased precipitation, necessitating shift...
Lower Mekong River Basin (LMRB) Satellite remote sensing products are widely used for monitoring droughts. Using NASA satellite sensors of precipitation (Global Measurement Mission, GPM), soil moisture (Soil Moisture Active and Passive, SMAP), terrestrial water storage (Gravity Recovery Climate Experiment, GRACE), this study evaluates the historical drought in LMRB during 2015–16. SMAP was validated against in-situ moisture, GPM were cross-validated with streamflow observations. The...
The Great Salt Lake is a closed basin lake in which level and volume fluctuate due to differences between inflows outflows. only outflow evaporation, depends directly on area salinity, both of depend volume. lake's level, volume, adjust balance, average, precipitation streamflow by evaporation. In this paper, we examine the sensitivity changes precipitation, streamflow, evaporation interactions among these processes salinity related A mass balance model developed generate representative...
Global climate change (GCC) is projected to bring higher-intensity precipitation and higher-variability temperature regimes the Northeastern United States. The interactive effects of GCC with anthropogenic land use cover changes (LULCCs) are unknown for watershed level hydrological dynamics nutrient fluxes freshwater lakes. Increased can promote harmful algal blooms, also exacerbated by warmer water temperatures due GCC. To address complex interactions climate, humans, we developed a...
Study region: Malibu Creek and Ventura watersheds, California, USA.Study focus: Fires significantly alter how watersheds respond to precipitation, leading increased runoff rates heightened sediment loads. We used the Soil Water Assessment Tool (SWAT) analyze discharge Our assessment compared Woolsey Thomas Wildfire episodes on loads generated from burned unburned areas within watersheds. New hydrological insight for Following Wildfire, surged between 2.1 5.2 times, while escalated by 1.9...
The current influx of climate related information required scientists to communicate their findings decision makers in governments, disaster preparedness organizations, and the general public. Soil Water Assessment Tool (SWAT) is a powerful modelling tool that allows simulate many physical processes involved water cycle. This article presents design, methods development efforts overcome some limitations previously developed SWAT visualization software programs by creating set modular web...
Lake Champlain Basin, northwestern New England, USA. Our study uses regional hydrologic analyses and modeling to examine alternative possibilities that might emerge in the Basin streamflow regime for various climate scenarios. Climate data as well spatial were processed calibrate Regional Hydro-Ecological Simulation System (RHESSys) model runoff simulations. The 21st century simulations obtained by driving RHESSys with from Coupled Model Intercomparison Project phase 5 (CMIP5) representative...
Abstract With mounting scientific evidence demonstrating adverse global climate change (GCC) impacts to water quality, quality policies, such as the Total Maximum Daily Loads (TMDLs) under U.S. Clean Water Act, have begun accounting for GCC effects in setting nutrient load‐reduction policy targets. These targets generally require reductions attaining prescribed standards (WQS) by safe levels of concentrations that curtail potentially harmful cyanobacteria blooms (CyanoHABs). While some...
The Great Salt Lake is a terminal lake whose level determined by the balance between inflows and outflows. We examine causes for multimodality in distributions of hence volume area that have previously been examined from system dynamics perspective. focus on role bathymetry this show some modes are observed represent preferred states attributable to features described using topographic area‐volume relationship. Being lake, only “outflow” evaporation, which depends directly area, adjusts...
In 'Satellite observations and modeling to understand the Lower Mekong River Basin streamflow variability' [1] hydrological fluxes, meteorological variables, land cover use maps, soil characteristics parameters data were compiled processed for Basin. this work, daily time series at nine gauges located five different countries in region (Thailand, Laos People׳s Democratic Republic (PDR), Myanmar, Cambodia, Viet Nam) is presented. Satellite-based precipitation air temperature (minimum &...
In this work, we used the Regional Hydro-Ecological Simulation System (RHESSys) model to examine runoff sensitivity land cover changes in a mountain environment. Two independent experiments were evaluated where conducted simulations with multiple vegetation that include conversion grass, no and deciduous/coniferous scenarios. The performed at two hillslopes within Weber River near Oakley, Utah watershed (USGS gauge # 10128500). Daily precipitation, air temperature wind speed data as well...
The recently announced Freshwater Challenge (FWC) initiative (https://www.freshwaterchallenge.org/) at the United Nations Water conference, sets an ambitious goal of restoring 300,000 kilometers degraded rivers and 350 million hectares wetlands across globe by 2030. Central to moving towards this will be including tangible actions for freshwater linked ecosystems into supporting country’s Nationally Determined Contributions (NDCs) National Biodiversity Strategies Action Plans...
Abstract. NASA has launched a new initiative; the Open-Source Science Initiative (OSSI) to enable and support science towards openness. The OSSI initiative supports open-source software development dissemination. In this work, we present NASAaccess which is an package web-based environmental modeling application for earth observation data accessing, reformatting, presenting quantitative products. main objective of developing platform facilitate exploration, modeling, understanding...
