In Pakistan, many subsurface (SS) drainage projects were launched by the Salinity Control and Reclamation Project (SCARP) to deal with twin problems (waterlogging and salinity). In some cases, sump pumps were installed for the disposal of SS effluent into surface drainage channels. Presently, sump pumps have become dysfunctional due to social and financial constraints. This study evaluates the alternate design of the Paharang drainage system that could permit the discharge of the SS drainage system in the response of gravity. The proposed design was completed after many successive trials in terms of lowering the bed level and decreasing the channel bed slope. Interconnected MS-Excel worksheets were developed to design the L-section and X-section. Design continuity of the drainage system was achieved by ensuring the bed and water levels of the receiving drain were lower than the outfalling drain. The drain cross-section was set within the present row with a few changes on the service roadside. The channel side slope was taken as 1:1.5 and the spoil bank inner and outer slopes were kept as 1:2 for the entire design. The earthwork was calculated in terms of excavation for lowering the bed level and increasing the drain section to place the excavated materials in a specific manner. The study showed that modification in the design of the Paharang drainage system is technically admissible and allows for the continuous discharge of SS drainage effluent from the area.

Soil salinity and alkali pose a major problem for agriculture in West Pakistan. According to one estimate [5, p. 39], out of the gross area of 46.5 million acres of the Indus Plains, 4.8 million acres were strongly saline and 11.1 million acres were partially affected by salinity. Although soil alkali was also recognized as a problem [1], it was generally considered to be of limited extent. Its full significance was realized only after studies in 1962 and 1963 by the Water and Soil Investigation Division of WAPDA and the US Salinity Laboratory in the Salinity Control and Reclamation Project No. 1 (WAPDA 1966). The soil surveys carried out by the Soil Survey Project of Pakistan have subsequently provided further information on saline and alkali soils.

Over the last few decades there has emerged a small, yet influential eco-Buddhism movement in South Korea which, since the turn of the millennium, has seen several S?n (J. Zen) Buddhist clerics engage in high-profile protests and activism campaigns opposing massive development projects which threatened widespread ecological destruction. This article will survey the issues and events surrounding three such protests; the 2003 samboilbae, or ‘threesteps- one-bow’, march led by Venerable Suky?ng against the Saemangeum Reclamation Project, Venerable Jiyul’s Anti-Mt. Ch?ns?ng tunnel hunger-strike campaign between 2002 and 2006, and lastly Venerable Munsu’s self-immolation protesting the Four Rivers Project in 2010. This article will additionally analyze the attempts by these clerics to deploy innovative and distinctively Buddhist forms of protest, the effects of these protests, and how these protests have altered public perceptions of the role of Buddhist clergy in Korean society. This study will additionally highlight issues relevant to the broader discourse regarding the intersection of Buddhism and social activism, such as the appropriation of traditional Buddhist practices as protest tactics and the potential for conflict between social engagement and the pursuit of Buddhist soteriological goals.

AbstractIntegrated renovation projects are important for marine ecological environment protection. Three-dimensional hydrodynamics and water quality models are developed for the Maowei Sea to assess the hydrodynamic environment base on the MIKE3 software with high resolution meshes. The results showed that the flow velocity changed minimally after the project, decreasing by approximately 0.12 m/s in the east of the Maowei Sea area and increasing by approximately 0.01 m/s in the northeast of the Shajing Port. The decrease in tidal prism (~ 2.66 × 106 m3) was attributed to land reclamation, and accounted for just 0.86% of the pre-project level. The water exchange half-life increased by approximately 1 day, implying a slightly reduced water exchange capacity. Siltation occurred mainly in the reclamation and dredging areas, amounting to back-silting of approximately 2 cm/year. Reclamation project is the main factor causing the decrease of tidal volume and weakening the hydrodynamics in Maowei Sea. Adaptive management is necessary for such a comprehensive regulation project. According to the result, we suggest that reclamation works should strictly prohibit and dredging schemes should optimize in the subsequent regulation works.
