Abstract Climate change impacts on precipitation characteristics will alter the hydrologic characteristics, such as peak flows, time to peak, and erosion potential of watersheds. However, many currently available climate datasets are provided at temporal spatial resolutions that inadequate quantify projected changes in a watershed. Therefore, it is critical temporally disaggregate coarse-resolution data finer for studies sensitive characteristics. In this study, we generated novel 15-minute...

The determination of field capacity (FC), irrigation thresholds, and amounts is characterized by site-specific soil hydraulic properties (SHPs). This study, conducted in two zones (zone 1 zone 2) delineated based on soil, topography, historical crop yield Alabama (USA), focused determining zone-specific FC using negligible drainage flux qfc criterion. HYDRUS-1D model was used to optimize SHPs measured matric potential (h). FCs were determined optimized raw at 0.01 cm/day as qfc. results...

Abstract. The flow duration curve (FDC) of streamflow at a specific site has key role in the knowledge on distribution and characteristics that site. FDC gives information water regime, providing to optimally manage resources river. In spite its importance, because lack gauging stations, construction can be not straightforward task. partially gauged basins, FDCs are usually built using regionalization among other methods. this paper we show is characteristic basin only, but both weather....

Highlights Phosphorus and nitrogen in soil plants varied during the growing season across cornfield. Spatial variability nutrients caused spatial plant growth crop yield Hydrological characteristics hydraulic properties were responsible for nutrients. Need to consider delineating management zones before adopting practices. Abstract . The adoption of precision agricultural practices Alabama has been increasing recent years. Although challenging, understanding nutrient fields is important...

Land and water resources are the basic needs of agriculture for economic development any country.As becomes increasing scare demand irrigation water, everywhere, has now focused national attention public interest on utilization existing supplies, integrated conservation management policy practices.Accurate quantification evapotranspiration is crucial better allocation resources.It important that requirements crops known at different levels within irrigated area to accomplish effective...

Highlights The greatest heterogeneity in soil water was observed at 30-60 cm depth a corn field and 0-15 cotton field. Spatiotemporal variability did not increase with increasing all layers both croplands during the growing season. Water excess stress locations were identified fields. A single, temporally stable location each field, which can be used for precise uniform irrigation. Knowledge of stability useful determining number sensors to install crop fields assist irrigation scheduling...

Abstract. The Flow Duration Curve (FDC) set up at a specific site has key role to the knowledge of streamflow characteristic that site. FDC gives information on water regime providing important optimally manage resources river. Spite its importance, because lack gauging stations, construction can be not straightforward task. In ungauged or partially gauged catchments, FDCs are usually built using regionalization methods among others. this paper we show is basin only, but both and weather....

<h3>ABSTRACT</h3> TEMPO nanofibrillated cellulose (TNFC), (NFC), carboxymethyl (CMC), and lignin were used as templates for the addition of two well-known antimicrobial substances, benzalkonium chloride (BZK) copper. The resulting hybrid materials analyzed biocidal activity in three separate products. Assays nanocellulose-antimicrobials assayed viability against <i>Escherichia coli</i> suspension, <i>Saccharomyces cerevisiae</i> on PVA plastic, <i>bacillus lincheniformis</i> paper additives....

The southeastern United States observed a widespread expansion in area under irrigation over the past half century, primarily due to inadequate rainfall during crop growing season. In this region, El Niño Southern Oscillation (ENSO), seasonal-to-interannual climate-variability phenomena, may result bringing suitable precipitation any year while generating extremes of too much or little others. Therefore, climate variability phenomena results uncertainties availability stream water for...

Abstract In the Southeast US, El Niño Southern Oscillation (ENSO), climate variability phenomena affect quantity of water that is available for irrigation. The goals this study were to determine effect upstream surface withdrawals irrigation on in downstream areas as a function ENSO phase and quantify watershed area can be irrigated using withdrawn from streams an ecologically sustainable manner. was conducted Swan Creek (97 km2) located Limestone County, Alabama, USA. soil assessment tool...

Drip or trickle irrigation is one of the latest methods which becoming increasingly popular in areas with water scarcity and salt problems. The Government India recognized importance micro announced subsidy schemes few selected states 1991. Different crops require different plant spacings requirements. general layout system location emitters will depend on type crop. This paper describes a windows based computer application developed for designing efficient drip facilities using Visual Basic...

With the increasing trend of greenhouse gases in atmosphere, by 2052 temperature is expected to rise 1.5 from Pre-industrial Period, affecting future extreme rainfall events.

Water is increasingly becoming a limited resource due to rising demands for various uses, including hydropower generation, irrigation, and domestic supply. As the population grows, need water across different sectors constantly increases. However, availability of resources restricted both spatially temporally. Therefore, there an urgent systematic scientific planning ensure its optimal use. Agriculture sector being major consumer resources, adoption modern irrigation techniques can...
