This study aims to validate the HEC-HMS model in Karnali river basin of Nepal, while also physically verifying parameters for area. The is a semi-distributed based that requires site-specific information about weather, as well spatial on soil and land use. Using Arc-GIS, HEC-HMS, HEC DSS, hydrological rainfall runoff was developed River at Asaraghat (DHM station 240) period 1998-2005. Calibrati...

Two headwater tributaries of the Little Muskingum River were compared to assess possible effects of oil field brines on biological integrity of the streams. Diatom, macroinvertebrate, and fish communities were analyzed during the summer, 1990, for possible changes in community-structure caused by brines. Dissolved chemicals associated with brines and natural surface waters were quantified month...

Switch toggling games such as Lights Out and the σ-game are widely studied in mathematics and have been applied to model a variety of situations such as genetic networks and cellular automata. This paper introduces a class of toggling games where at each iteration a fixed number of switches is chosen to be toggled where the only switches changed are the switches chosen to be toggled. The switch...

The influences of climate change on water resources availability in Jinjiang Basin, China, were assessed using the Block-wise use of the TOPmodel with the Muskingum-Cunge routing method (BTOPMC) distributed hydrological model. The ensemble average of downscaled output from sixteen GCMs (General Circulation Models) for A1B emission scenario (medium CO2 emission) in the 2050s was adopted to build...

After the Paris Agreement was signed in 2015, many countries worldwide focused on hydrogen economy, aiming for eco-friendly and renewable energy by moving away from existing carbon which has been primary source of global warming. Hydrogen is most common element Earth. As a light substance, can diffuse quickly; however, it also small risk explosion. Representative explosion accidents have includ...

The U.S. Army Corps of Engineers elevated Zoar Levee and Diversion Dam to a Dam Safety Action Class I (urgent and compelling) ranking due to seepage concerns. An accelerated program is in progress to address project deficiencies which include seepage through the levee’s glacial outwash foundation, through a fractured rock knoll beneath the levee, and through the dam’s fractured rock abutments a...

The interaction between groundwater (GW) and surface water (SW) not only sustains runoff in dry seasons but also plays an important role river floods. Lateral inflow is the recharge of to during a flood; this part GW-SW exchange. Hydrological engineers proposed idea modelling flood routing using Muskingum-Cunge method, which exchange fully considered. This study proposes improved nonlinear mode...

The amount of rainfall can be used to estimate the runoff that enters a reservoir. Runoff is influenced by land use, and soil type greatly affects will occur. This study discusses development hydrological model with application Hydrologic Engineering Center (HEC-HMS) in Karangmumus watershed using data has been verified field divided into zones based on permeability testing laboratory. With hel...
