 note = {There is soil salinity problem in northeastern Thailand. Particularly, in the lower Nam Kam
River which is a branch of the Mekong River, have salinity problem in groundwater. Then, farmers cannot
get agricultural water in the dry season. Because water level in the Mekong River is highly change in the
dry and wet seasons. Royal Irrigation Department(RID) make a plan to set a regulator in the Nam Kam
River to control water level before flowing to the Mekong River and build a reservoir in the lower part of
this river basin. As the results, a reservoir existing in the lower Nam Kam River area through the year,
and infiltration volume in this area will be increased by ponded water in this reservoir. This is caused by
the Nam Kam control gate operation.The authors observed continuously groundwater levels in shallow
aquifer over 7 years. And we have collected land use crop pattern, water levels and climate data in the
Mekong and the Nam Kam River. Moreover, we have observed infiltration capacity 54 points and made
the distribution map of infiltration capacity in this area. Using these data, the authors calculated the
infiltration rate change during these periods. This paper shows those results and estimates the influence
to groundwater level by setting the control gate in the lower Nam Kam River.},
