✦ Synopsis

This Special Issue of Hydrological Processes (herein referred to as HYP-JSI 10) is the tenth volume to be published under the Editorial Board of the Japan Society of Hydrology and Water Resources (JSHWR).

A part of this issue features studies focusing on groundwater resource in the coastal megacity of Bangkok, Thailand, including the topics of groundwater flow system, contamination, anthropogenic change, and interaction between groundwater and sea water. The hydrological processes occur dynamically along with the anthropogenic activities at the interface of fresh water and sea water in the coastal megacities of Asia. The five papers in this special issue show unique and important findings relating to this topic; tracing a confined groundwater flow system under the pressure of excessive groundwater use in the lower central plain, Thailand; anthropogenic changes in a confined groundwater flow system in the Bangkok basin, Thailand; hydrogeological constraint on nitrate and arsenic contamination in Asian metropolitan groundwater; submarine groundwater discharge, and seawater circulation in a subterranean estuarine beneath a tidal flat.

In addition to these, five papers covering various fields of hydrology and water resources are included in this volume such as, comparative assessment of model structural uncertainty using a multi-objective optimisation method; simulation of complicated and diverse water systems accompanied by human intervention in the North China plain; climate change impacts on groundwater temperature change in the Sendai plain; Influence of freshwater input and bay reclamation on long-term changes in seawater residence times in Tokyo bay, Japan; uncertainty in land-cover datasets for global land-surface models derived from 1-km global land-cover datasets; estimation of potential changes in production of cereals under climate change scenarios. The editors believe that all papers show a broad potential in the research of hydrology and water resources issues in Japan.

JSHWR celebrated its 22nd anniversary in 2010. The membership of JSHWR is approximately 1700 and an annual scientific meeting is held during the end of summer. This year's meeting was successfully held at the beginning of September 2010 in Tokyo, with approximately 350 participants. The JSHWR is an interdisciplinary society that covers a broad spectrum of hydrology and water resources issues, aiming to exchange views, information, and new knowledge among these fields. An open-access online letter journal on hydrological scientific issues-Hydrological Research Letters (HRL at http://www.jshwr.org/hrl/) has just celebrated its 3rd anniversary in July 2010. We believe that HRL will provide on-demand topics in Asian Hydrology into Hydrological Processes which features full scientific papers in global coverage through establishment of cross references.
