River water salinity is a significant concern in many countries, considering agricultural and drinking usages. Therefore, prediction of amount of salinity is a necessary tool for planning and management of water resources. Since Achechay River Basin in East Azerbaijan province in Iran passes through saline zones, use of the water for irrigation has become problematic. In this regard, prediction...

irrigation with saline water needs to the different managements to reduce the harmful effects of salinity on plants, soil and the environment. simulation models are the useful tool to irrigation management in conditions of soil and water salinity because, they can predict crop yield and soil conditions considering to different climate, plant and management practices. in this study, the saltmed ...

This paper describes the development of a comprehensive flow and salinity monitoring system and application of a decision support system (DSS) to improve management of seasonal wetlands in the San Joaquin Valley of California. The Environmental Protection Agency regulates salinity discharges from non-point sources to the San Joaquin River using a procedure known as the total maximum daily load ...

Salinity is one of the most brutal environmental factors limiting the productivity of crop plants because most of the crop plants are sensitive to salinity caused by high concentrations of salts in the soil, and the area of land affected by it is increasing day by day. For all important crops, average yields are only a fraction - somewhere between 20% and 50% of record yields; these losses are ...

A key issue for agriculture in irrigated arid lands is the control of soil salinity, and this is one of the goals for irrigated districts when changing from flood to sprinkling irrigation. We combined soil sampling, proximal electromagnetic induction, and satellite data to appraise how soil salinity and its distribution along a previously flood-irrigated field evolved after its transformation t...

BACKGROUND Picophytoplankton (i.e. cyanobacteria and pico-eukaryotes) are abundant and ecologically critical components of the autotrophic communities in the pelagic realm. These micro-organisms colonized a variety of extreme environments including high salinity waters. However, the distribution of these organisms along strong salinity gradient has barely been investigated. The abundance and co...

The first model calculates how long changes to deep drainage take to appear as recharge to saline aquifers. The second models the groundwater flows to quantify how much saline groundwater will be delivered to the River Murray over a certain period of time. SIMRAT has influenced salinity policy development, delivered outputs required by policy and continually challenged our understanding of sali...

This paper presents a method for predicting areas at risk from dryland salinity using information derived from multi-temporal Landsat TM satellite images combined with landform data derived from high-quality digital elevation models. The method is applied in the south west agricultural region of Western Australia to predict areas at risk from dryland salinity. This paper presents modifications ...

Hyperspectral remote sensing is widely used for analyzing and estimating the severity of soil salinity in arid and semi-arid regions, throughout the world. The present study is an attempt to map the various soil salinity severity classes using different hyperspectral indices generated using EO-1 Hyperion data and Support Vector Machine (SVM) method, in the Mathura region of Indo-Gangetic plain ...

Salt evaporation ponds have played an important role as habitat for migratory waterbirds across the world, however, efforts to restore and manage these habitats to maximize their conservation value has proven to be challenging. For example, salinity reduction has been a goal for restoring and managing former salt evaporation ponds to support waterbirds in the South Bay Salt Pond Restoration Pro...
