The increase in population and the human activities this basin area has led to many water shortage problems. This research was carried out investigate impacts of land-use changes urbanization on discharge Langat River Basin using ArcGIS. It applied Soil Water Assessment Tool (SWAT). aimed identify how critical increment could impact discharge. rainfall, humidity, solar, wind speed data from 201...

This article presents snow hydrology updates made to iTree-Hydro, previously called the Urban Forest Effects—Hydrology model. iTree-Hydro Version 1 was a warm climate model developed by the USDA Forest Service to provide a process-based planning tool with robust water quantity and quality predictions given data limitations common to most urban areas. Cold climate hydrology routines presented in...

Abstract The traditional instantaneous unit hydrograph (IUH) is very useful for theoretical analysis and practical forecasting of floods owing to its linear assumptions. Although various revised methods overcome the unphysical assumptions have been proposed, it still difficult obtain efficiently a nonlinear IUH diverse rainfall excess intensities in watershed. In this study, we proposed physica...

the performance of the swat2012 model for estimation of hydrological budget in gharasou watershed, west of iran, during 1995 to 2005 was assessed. digital elevation model, hydro-climatological data, soil and land use maps with their properties relevant to the watershed were considered to fulfill the model. a branch program in swat-cup software (sufi2) program implemented to simulate and validat...

Wetting pattern geometry is useful in determining the spacing between emitters and irrigation time drip systems. This research aimed to generate an empirical model estimate width depth of wetting front surface based on experimental tests a cube-shaped container with transparent walls soils sandy clay loam texture, hydraulic conductivities from 2.316 3.945 cm h?1, organic matter contents 1.7 2.8...

Two methods are developed, when solving the related time-independent Schrodinger equation (TISE), to cope with the singular terms of the vibrational kinetic energy operator of a triatomic molecule given in orthogonal internal coordinates. The first method provides a mathematically correct treatment of all singular terms. The vibrational eigenfunctions are approximated by linear combinations of ...

Abstract. Karst trough and valley landforms are prone to flooding, primarily because of the unique hydrogeological features karst landforms, which conducive spread rapid runoff. Hydrological models that represent complicated hydrological processes in regions effective for predicting but their application has been hampered by complex model structures associated parameter set, especially distribu...

In the past few decades, water resources in Tang–Bai River Basin showed a declining trend, due to human–driven alteration of surface and groundwater management. There are potential risks sustainable utilization future response agricultural, industrial, domestic supply. this work, we used allocation regulation model based on SWAT (SWAT–WARM model) quantify characteristics under human activities ...

Abstract Increased sedimentation is the main problem that affects dam efficiency by reducing storage capacity. Planning for construction and maintenance requires design strategies heavily depend on integrated basin models, properly identifying principal sediment origins within watershed qualifying production rate. In this research work, physically-based SWAT model, defined as Soil Water Assessm...
