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.

Longitudinal dispersion in open channel flow with suspended canopies
Suspended canopies can cause flow disturbances such as reducing velocities within the canopy, and increasing flow beneath the canopy. Flow modifications by canopies dramatically affect the fate and transport of sediment, nutrients, contaminants, dissolved oxygen, and fauna in aquatic systems. A three-zone model is presented here to predict the longitudinal dispersion coefficient by simplifying Chikwendu's N-zone model. To validate the model, both flow field and tracer experiments were conducted using a straight...
iSTREEM®: An approach for broad‐scale in‐stream exposure assessment of “down‐the‐drain” chemicals
The iSTREEM® model (“in‐stream exposure model”), a web‐based model made freely available to the public by the American Cleaning Institute, provides a means to estimate concentrations of “down‐the‐drain” chemicals in effluent, receiving waters, and drinking water intakes across national and regional scales under mean annual and low flow conditions. We provide an overview of the evolution and utility of the iSTREEM® model as a screening‐level risk assessment tool relevant for down‐the‐drain products. The spatial...
A methodology for linking 2D overland flow models with the sewer network model SWMM 5.1 based on ...
Pluvial flooding in urban areas is characterized by a gradually varying inundation process caused by surcharge of the sewer manholes. Therefore urban flood models need to simulate the interaction between the sewer network and the overland flow in order to accurately predict the flood inundation extents. In this work we present a methodology for linking 2D overland flow models with the storm sewer model SWMM 5. SWMM 5 is a well-known free open-source code originally developed in 1971. The latest major release saw...
A refined groundwater flow model of the shallow aquifer in Tianjin Municipality, China
The assembly of a groundwater flow model for the shallow aquifer in Tianjin Municipality is outlined in this paper. Tianjin Municipality was selected because of its complicated hydrogeological conditions and rich data, which could be used to test a refined groundwater flow model for the shallow aquifer. When a shallow groundwater flow model is being assembled its recharge and discharge functions need to represent inflows from rainfall, irrigation return flows, seepage from rivers and reservoirs, and lateral...
Analyzing the turbulent flow on steep open channels
In channels with steep slopes, the flow is supercritical and the formation of roll waves is expected. In order to evaluate the flow behaviors in steep open channels, the Azad dam spillway is simulated numerically and its flow characteristics are compared with the physical model tests. In this study, the hydraulic variables including hydraulic depth and water surface profile are studied along the steep open channels. The k-ɛ turbulence model is considered in this study. It is shown that in the conditions in which...
