South Asia combines a low level of regional integration and the presence of relatively high trade barriers. The proportion of trade originating in the region has increased in the last decade but still lags behind many similar regional arrangements. The present study employs an augmented gravity model to examine the impact of a set of macroeconomic and other policy factors on trade flows in the South Asian Association for Regional Cooperation (SAARC) region. The interesting finding is that export between two countries would increase by 152.2%, if there exists a bilateral trade agreement between countries compared to country-pairs without having bilateral trade ties. The empirical analysis reveals that reduction in tariff level is also a better measure to improve trade in the region. Further, the study supports specialisation in the region based on the relative factor endowments and cost advantage as well.

Assessing methods for estimating roughness coefficient in a vegetated marsh area using Delft3D
A Delft3D-FLOW model was used to simulate tidal flow in Davis pond marsh in Louisiana, USA. The study area is a freshwater marsh consisting of one main channel and floodplain. Vegetation-induced flow resistance greatly influences tidal flow dynamics in the marsh. This study evaluated eight approaches to estimate vegetation roughness, including two constant Manning's n values, four empirical relations for calculating n, and two methods for calculating Chezy's C values originally embedded in the Delft3D model....
Modeling effect of cover condition and soil type on rotavirus transport in surface flow
Runoff from animal production facilities contains various microbial pathogens which pose a health hazard to both humans and animals. Rotavirus is a frequently detected pathogen in agricultural runoff and the leading cause of death among children around the world. Diarrheal infection caused by rotavirus causes more than two million hospitalizations and death of more than 500,000 children every year. Very little information is available on the environmental factors governing rotavirus transport in surface runoff....
Determination of Flow Rates in part-filled Applications using the Radar Method
Introduction The radar measurement method plays an increasingly important role in the water and wastewater field. This is particularly reflected by the "Metering outside of the medium" trend. Flow measurement using radar which enables contactless measurements thus becomes a major focal point. It features a wide range of applications and hence is useful as permanent measurement system for many applications with part filled pipes or canals in the water and wastewater field. Flow Rate Determination The determinatio...
Development of two-dimensional groundwater flow simulation model using meshless method based on MLS ...
In recent decades, due to reduction in precipitation, groundwater resource management has become one of the most important issues considered to prevent loss of water. Many solutions are concerned with the investigation of groundwater flow behavior. In this regard, development of meshless methods for solving the groundwater flow system equations in both complex and simple aquifers' geometry make them useful tools for such investigations. The independency of these methods to meshing and remeshing, as well as its...
Verification of CFD tool for simulation of cavitating flows in hydraulic systems
Cavitation is an undesirable phenomenon in hydraulic systems, as it causes erosion and noise. The main difficulty in cavitation prediction when using Fluent software is lack of an openly accessible tool for implementation of a freely chosen homogeneous cavitation model. In this paper the main challenge is to make such a tool, user defined function (UDF). The second challenge is to use a qualitative method in the assessment of the results of verification process. Three cavitation models are verified in Fluent...
