Abstract Storm events dominate riverine loads of dissolved organic carbon (DOC) and nitrate are expected to increase in frequency intensity many regions due climate change. We deployed three high‐frequency (15 min) situ absorbance spectrophotometers monitor DOC concentration for 126 storms watersheds with agricultural, urban, forested land use/land cover. examined intrastorm hysteresis the influences seasonality, storm size, dominant cover on loads. was generally anticlockwise at all sites,...
Landslides, floods, and droughts are recurring natural disasters in Nepal related to too much or little water. The summer monsoon contributes more than 80% of annual rainfall, rainfall spatial inter-annual variation is very high. Gandaki River, one the three major rivers tributaries Ganges covers all agro-ecological zones central part Nepal. Time series tests were applied for different River Basin (GRB) trends four seasons (pre-monsoon, monsoon, post-monsoon winter) from 1981 2012....
This paper presents temporal and spatial pattern of drought phenomena in central Nepal using standardized precipitation index (SPI) at multiple time scales. The study is based on 32 years monthly data from 40 meteorological stations 1981 to 2012. Results indicate that, while there no distinct trend regional precipitation, interannual variation large. Trend analysis shows that most are characterized by increases both severity frequency stronger for longer Over the period, summer season 2004,...
Precipitation in mountain regions is often highly variable and poorly observed, limiting abilities to manage water resource challenges. Here, we evaluate remote sensing ground station-based gridded precipitation products over Nepal against weather station observations on a monthly timescale. We find that the Tropical Rainfall Measuring Mission (TRMM) 3B-43 product exhibits little mean bias reasonable skill giving Nepal. Compared observations, TRMM showed an overall Nash-Sutcliffe efficiency...
Abstract Snow is an important component of the water resources New York State and watersheds reservoirs City (NYC) supply. In many NYC supply hydrologic regimes high‐elevation headwaters are linked to streamflow channel processes in low‐elevation stream reaches that serve as inputs reservoirs. To better simulate this linkage there a need understand spatial variations snowpack snowmelt. Snowmelt hydrology Soil Water Assessment Tool (SWAT) model where spring runoff strongly affected by melting...
Rain-on-snow (ROS) runoff events are important hydro-meteorological phenomenon due to their association with flooding. The severity of ROS depends on the magnitude precipitation, air temperature elevation, snow water equivalent (SWE), and areal extent antecedent snowpack. Examining consequences these factors acting together creates challenges for both flood prediction risk assessments. This study provides information spatial patterns, seasonality in New York. We examine temporal variability...
This paper describes Nepal’s national livestock policies and considers how they can be improved to help meet the pressing challenges of economic development, equity, poverty alleviation, gender mainstreaming, inclusion marginalized underprivileged communities, climate vulnerability. Nepal is in process transforming its government from a unitary system federal democratic structure through new constitution expected by 2015, offering opportunity bring set priorities stakeholders policymaking....
Abstract Recent works have indicated that climate change in the northeastern United States is already being observed form of shorter winters, higher annual average air temperature, and more frequent extreme heat precipitation events. These changes could profound effects on aquatic ecosystems, implications such are less understood. The objective this study was to examine how future temperature translate into streamflow using a physically based semidistributed model, subsequently potentially...
Suburban growth and its impacts on surface runoff were investigated using the soil conservation service curve number (SCS-CN) model, compared with integrated advanced remote sensing geographic information system (GIS)-based approach, over South Kingston, Rhode Island, USA. This study analyzed employed supervised classification method four Landsat images from 1994, 2004, 2014, 2020 to detect land-use pattern changes through applications. Results showed that 68.6% urban land expansion was...
Improved irrigation use efficiency is an important tool for intensifying and diversifying agriculture in Nepal, resulting higher economic yield from irrigated farmlands with a minimum input of water. Research was conducted to evaluate the effect method (furrow vs. drip) on productivity nutritious fodder species during off-monsoon dry periods different elevation zones central Nepal. A split-block factorial design used. The factors considered were treatment location, crop, method. Commonly...
Around 40% of the world’s population depends on coastal aquifers for freshwater supply but natural and anthropogenic drivers threaten groundwater availability. Of these drivers, saltwater intrusion (SWI) is one most critical increasingly affecting areas worldwide. Interest in has significantly increased, as demonstrated by growing number publications which researchers describe various approaches to illuminate importance aquifers, specifically with regard SWI. The state research knowledge SWI...
Abstract This study focuses on the effect of projected changes in rainfall, snow accumulation and snowmelt, consequent timing runoff NYC water supply system storage operation as simulated by reservoir Operational Analysis Simulation Integrated Systems (OASIS) model. The Generalized Watershed Loading Functions—Variable Source Area (GWLF‐VSA)—watershed model is used with future climate scenarios derived from different General Circulation Models (GCMs) to simulate inflows reservoirs that are...
Abstract Snowfall is an important part of the yearly water balance for Catskill Mountains in New York State, location supply reservoirs City. Recent studies have shown that effects climate change on hydrology Catskills will most likely create (1) a decrease proportion precipitation falling as snow, (2) shift timing snowmelt cause snowmelt‐supplemented streamflow events to occur earlier fall and winter, (3) magnitude traditionally high April streamflow. The snowmelt‐influenced measured by...
The general practice of rainfall-runoff model development towards physically based and spatially explicit representations hydrological processes is data-intensive computationally expensive. Physically models such as the Soil Water Assessment tool (SWAT) demand spatio-temporal data expert knowledge. Also, difficulty complexity compounded in smaller watershed due to constraint models’ inability generalize hydrologic processes. Data-driven can bridge this gap with their mathematical...
Climate studies have suggested that inland stream temperatures and average streamflows will increase over the next century in New England, thereby putting aquatic species sustained by coldwater habitats at risk. This study uses Soil Water Assessment Tool (SWAT) to simulate historical streamflow within three forested, baseflow-driven watersheds Rhode Island, USA followed simulations of future climate scenarios for comparison. Low greenhouse gas emission are based on 2007 International Panel...

Abstract. The cycling of carbon (C) in terrestrial ecosystems is closely coupled with the water. An important mechanism connecting ecological and hydrological processes lateral flow water along landscapes. Few studies, however, have examined explicitly how consideration routing affects simulated C dynamics ecosystems. objective this study to explore a process-based hydro-ecological model dynamics. To achieve that end, we rasterized regional simulation system (RHESSys) employed RHESSys...
