The rapid increase of paddy field acreage has led to widely descending of groundwater table in well irrigation paddy area of low-land in Sanjiang Plain recent years. More and more “hanging pump” and partial over pumping phenomenon have been occurring in well irrigation paddy area of low-land. Therefore, the groundwater resources in Sanjiang Plain need to be recharged urgently. For solving the m...

Relevance Vector Machine (RVM) is a novel kernel method based on Sparse Bayesian, which has many advantages such as its kernel functions without the restriction of Mercer’s conditions, the relevance vectors automatically determined. In this paper, a new RVM model optimized by Particle Swarm Optimization (PSO) is proposed, and it is applied to groundwater level forecasting. The simulation experi...

The Restionaceae species of the Fynbos biome is part of the Cape Floristic Kingdom is threatened by urbanization, agricultural expansion, groundwater extraction, and climate change. Therefore, it is necessary to assess and monitor the Restionaceae species under the impact of climate change. South Africa is a semi-arid environment, and hydrological factors are the main variables in the determina...

abstract level of groundwater is decreased which is mainly because, withdrawal of groundwater is increased, because of lack of right management. economics of rural based farming and farming is dependent of water so decreasing of groundwater effects social welfare. in this study decrease of welfare measure by reason of reduction of groundwater level considered. this study investigated the impact...

Given the societal concern about groundwater pollution from agricultural sources, public programs have been proposed or implemented to change farmer behavior with respect to nutrient use and management. However, few of these programs designed to change farmer behavior have been evaluated due to the lack of detailed data over an appropriate time frame. The Central Platte Natural Resources Distri...

Abstract Drought and water scarcity can significantly impair the sustainable development of groundwater resources, a scenario commonly found in aquifers Mediterranean region. Water management measures to address these drivers depletion are highly relevant, especially considering increasing severity droughts under climate change. This study evaluates potential managed aquifer recharge (MAR) offs...

Climate change and anthropogenic activities are necessitating accurate diagnoses of seawater intrusion (SWI) to ensure the sustainable utilization groundwater resources in coastal areas. Here, vulnerability SWI was assessed by classifying existing GALDIT into static parameters (groundwater occurrence (G), aquifer hydraulic conductivity (A), distance from shore (D)) dynamic (height groundwater-l...
