“…Water shortages have led to increasing groundwater demand in many parts of the world [15,48]. Groundwater abstraction has also become an important complementary water source in Thailand, and the water table has been found to decrease in several regions of the Younger Aquifer in the Upper Central Plain of the Chao Phraya River of Thailand [49].…”

Droughts grow concurrently in space and time; however, their spatiotemporal propagation is still not fully studied. In this study, drought propagation and spatiotemporal characteristics were studied in northern, northeastern, and central Thailand (NNCT). The NNCT is an important agricultural exporter worldwide, and droughts here can lead to considerable pressure on the food supply. This study investigated meteorological drought and soil drought in northern Thailand and identified 70 meteorological drought events and 44 soil drought events over 1948–2014. Severe droughts (droughts with long trivariate return periods) mainly occurred after 1975 and were centered in northern and northeastern Thailand. Meteorological drought and soil drought that occurred during 1979–1980 had the longest trivariate return periods of 157 years and 179 years, respectively. The drought centers were mainly located in the Chao Phraya River basin and the Mun River basin. The mean propagation ratios of all drought parameters (duration, area, severity) were lower than 1, indicating that the underlying surface can serve as a buffer to alleviate water deficits. Most of the probability distribution coefficients and all drought propagation ratios of the three drought parameters were found to change significantly based on a moving-window method, indicating that the drought parameters and propagation from meteorological drought to soil drought were non-stationary. Significant increasing trends were detected in mean values of most drought parameters, ranging from 2.4%/decade to 16.6%/decade. Significant decreasing trends were detected in coefficients of skewness (Cs) of all drought parameters and coefficients of variation (Cv) of most drought parameters, ranging from −3.3 to −12.4%/decade, and from −5.5 to −19.4%/decade, respectively. The propagation ratios of all drought parameters showed significant increasing trends, indicating that the function of the underlying surface as a buffer has become weaker. The drought propagation ratios were found to be positively related to two climate indices, the phase index (PI) and the climate seasonality index (CSI). These findings will help to develop a better understanding and management of water resources in Thailand.

“…Além disso, devido à grande variação espacial dos dados referentes a água subterrânea, a krigagem destaca-se por ser um método não-determinístico, que, ao modelar também a magnitude ideal efeito pepita (nugget), cria uma superfície de interpolação suavizada com melhor capacidade de previsão dos resultados (MONTÉS, 1994). A krigagem tem sido amplamente utilizada na interpolação de dados de água subterrânea, com resultados satisfatórios, se comparados a outros métodos (GUNDOGDU; GUNEY, 2007;AHMADI e SEGHAMIZ;2008;MOSLEMZADEH et al, 2011;VASCONCELOS et al, 2017).…”

Este artigo tem como objetivo identificar corpos hídricos e poços no Município de São Paulo sob risco relativo à proximi-dade áreas de solos contaminados. Foram traçados raios de segurança entre as áreas contaminadas e os potenciais alvos de contaminação, conforme as características hidrogeológicas dos aquíferos. Assim, foi possível determinar inter-seções com rios e poços, mapeando-os como sob risco de contaminação. Em seguida, produziu-se um mapa de impacto acumulado da poluição na hidrografia, traduzindo a topologia hidrológica levando em consideração os potenciais pontos de contaminação à montante. Também foi mapeada a vulnerabilidade dos lençóis freáticos à contaminação, por meio de um índice de vulnerabilidade de aquíferos que considera a condutividade hidráulica e a profundidade da camada não saturada do aquífero. 49 poços (1,68%) apresentaram potencial de contaminação, sendo que 65,31% deles são declarados como de abastecimento humano, e localizam-se predominantemente em áreas com alta densidade popula-cional e vulnerabilidade extremamente alta de contaminação dos aquíferos. Nesse contexto, contribuiu-se para análise da situação dos recursos hídricos de São Paulo, para que usuários e o poder público possuam ciência dos riscos de contaminação e, assim, priorizar as medidas preventivas quanto a esses riscos.

The Impact of Climate Change on Groundwater Resources System Under Conjunctive Use in the Upper Central Plain

The Upper Central Plain Basin of Thailand has high potential for social and economic development. It is also high-volume source of agricultural products, especially rice. However, in the drought year, water storage in the dams is inadequate to allocate for agriculture, and caused water deficit in many irrigation projects. Farmers need to find extra source of water by pumping the groundwater. This area is also affected from climate change phenomena, which cause significant decrease of the water storage in the dam and may cause further shortage in the future. The objective of this study is to characterize of groundwater system under conjunctive use, to analyze the impact of climate change, and to propose adaptation measures under climate change to alleviate drought in the future. Based on the analysis of groundwater systems in the present period, it was found that significant factors affecting groundwater storage are land recharge and groundwater pumping. The study developed the climate-soil based recharge formula that described the relationship between land recharge and rainfall, climate condition parameters and produced groundwater pumping potential map which classify the study area into 3 zones: low potential, intermediate potential and high potential for future pumping planning. The study of climate change impact concludes that the average demand, surface water supply and groundwater pumping will increase. The conjunctive use ratio in wet season, in near future will be the same as present, while it will decrease 14.29% in the far future. In dry season, the ratio will increase 23.08% and 45.83%, respectively. The conjunctive use ratio in annual, will increase 6.59% and 6.18%, respectively. The two proposed adaptation measures will reduce drought risk under climate change in the near future and far future.
